Section 2: Quick User GuideInstallationThe MiniPurge® System must be installed by a competent engineer, in accordance with relevant standards,such as IEC / EN 60079-14 and any local codes or practice.

• Mount the purge system in accordance with the hook-up drawing.

• Ensure the system is installed according to the full instructions in the “Installation of the System” section of this manual.

• All pipings must be clean and free of dirt, condensation and debris prior to connection to the purge system or pressurized enclosure.

• It is strongly recommended that a local isolation valve is installed on the air supply upstream of the purge system.

Note: Most faults are due to restricted air supply, inadequate supply pipe work or drop in air supply pressure during the purge process.

Operation of the SystemOnce the system is installed correctly, turn on the air supply. Refer to Commissioning section.

The purge system commences the purge cycle:

• The purge air will enter the enclosure.

• The pressurized enclosure will obtain a positive pressure.

• The Purge Outlet Valve will open within the Relief Valve Unit.

• The air will then exit the Relief Valve Unit housing via the spark arrestor.

Open the Purge Flow Restrictor Valve until the air flow reaches the required rate; the system will initiate the timed purge cycle. Start a stopwatch when the purging indicator flashes yellow

On completion of an uninterrupted purge cycle of the required length, the system will indicate purge complete. Stop the stopwatch when the purging indicator stops flashing.

Indicator Colour Status

Alarm / Pressurized Red Low pressure alarm (enclosure pressure too low)

Purging Black Purge flow too low or not in purge mode


Alarm / Pressurized Green Pressurized (minimum enclosure pressure achieved)

Purging Black Purge flow too low


Alarm / Pressurized Green Pressurized

Purging Sequential flashing Yellow

Purge flow rate above minimum


Alarm / Pressurized Green Pressurized and in leakage compensation mode

ML511 | v12 Page4




Check stopwatch timing to verify that the actual purge time is equal to or greater than the required purge time.

Note: The recorded purge time must never be less than the required purge time.The system is now operating correctly in leakage compensation mode.

If the system has not performed as expected, check the installation thoroughly and ensure it has been carried out according to the instructions.

If an obvious problem has not been highlighted and corrected, follow the procedures in the Fault Finding section.

If all checks have been carried out and the system still does not perform as expected, contact your local distributor or Expo Technologies.

Section 3: Application SuitabilityMiniPurge® systems are certified for use in hazardous locations, where the hazardous location is non-mining (above ground) and the hazard is caused by flammable gasses, vapours or dust. Depending on the model the systems may be used in IECEx and ATEX Zone 1 and/or Zone 2 - Categories 2 and 3 respectively.

MiniPurge® systems may be used for hazards of any gas group. Apparatus associated with the MiniPurge® system, such as intrinsically safe signalling circuits and flameproof enclosures containing switching devices may be limited in their gas group. The certification documentation supplied with any such devices must be checked to ensure their suitability.

This system is primarily designed for use with compressed air. Where other inert compressed gasses are used (Nitrogen, for example) the user must take suitable precautions so that the build up of the inert gas does not present a hazard to health. Consult the Control of Substances Hazardous to Health (COSHH) data sheet for the gas used. Where a risk of asphyxiation exists, a warning label must be fitted to the pressurized enclosure.

The following materials are used in the construction of MiniPurge® systems. If substances that will adversely affect any of these materials are present in the surrounding environment, please consult Expo Technologies for further guidance.

Section 4: Description and Principle of OperationThe MiniPurge® system is pneumatic in operation, with electrical interfaces.

Purge and pressurization is a method of protection used in Zone 1 (21) and/or Zone 2 (22) hazardous locations to ensure that the interior of an enclosure is free of flammable gas. Addition of a MiniPurge® system allows the electrical equipment within the enclosure to be used safely in a hazardous location.

The principle of purge and pressurization is as follows:

• Clean compressed air or inert gas is drawn from a non-hazardous location.

• The interior of the pressurized enclosure is flushed to remove any hazardous gas or dust.

• This is introduced into the pressurized enclosure to keep the internal pressure at least 0.5 mbarg abovethe external pressure.

• Whilst pressurized, flammable gas cannot enter the enclosure from the environment.

Prior to switching on the power to the electrical equipment, the enclosure must be purged to remove any flammable gas that might have entered the enclosure before pressurization. Purging is the process of removal contaminated air and replacement with air (or inert gas) known to be free from flammable gas. The duration of this purge process is normally ascertained by performing a purge test.

At the end of the purge cycle the system automatically switches to leakage compensation mode. The Purge Outlet Valve is closed and the airflow is reduced but remains high enough to compensate for the leakage of air from the enclosure whilst maintaining the minimum over pressure state.

In the event of pressure failure within the pressurized enclosure the system will raise an alarm in the form of visual indicators and a volt free contact depending on the specification of the system. The default action on loss of pressurization is alarm and automatic disconnect of power (A&T - Alarm and Trip). This can be changed by the customer to Alarm Only (/AO), please refer to section titled Main Components.

The MiniPurge® system incorporates a Closed Loop Automatic Pressurization System (CLAPS). This allows the system to detect a rise or fall of the enclosure’s internal pressure and adjust the leakage compensation rate accordingly. Pressure variations are more likely during sudden start up of large rotating electrical machines but can also be caused by changes in running temperature. This system has been specifically designed to maintain a stable internal pressure within the enclosure.

ML511 | v12 Page6




Pressure characteristics during purge and pressurization of a pressurized enclosure using a MiniPurge® system that incorporates a CLAPS system:

Section 5: Main ComponentsAir Supply Filter / RegulatorThe unit is provided with a 40 μm liquid / dust filter element as a precaution. The user of the MiniPurge® system must ensure that air supply is to the quality stated in Air Supply Quality paragraph found in the Installation of the System section. The regulator is factory set to 4 barg (60 psig) and regulates the pressure of an air supply between 4 and 8 barg (60 to 120 psig). A pressure gauge is fitted down stream of the filter; this should indicate no less than 4 barg (60 psig). During the purge cycle a pressure drop will be indicated on the gauge.

Logic Air Supply RegulatorThis device provides the system with a stable air supply pressure to the logic system and allows consistent operation. The pressure level is factory set to 2.5 barg (36 psig) and can be verified by means of the integral pressure gauge.

Minimum Pressure SensorThis monitors the pressure inside the pressurized enclosure. When the pressure is below the minimum required for safe operation, the pressure sensor causes the system to reset and the Alarm / Pressurized indicator turns Red . The sensor is factory calibrated and set to operate in falling pressure at or above the minimum specified pressure.

Purge Flow SensorThe Purge Flow Sensor monitors flow through the Purge Outlet Valve. At correct purge flow rates, above the minimum specified for purging, the sensor sends a signal that activates the purge timer. This sensor is factory calibrated to operate on falling flow rate at or above the minimum specified purge flow rate.

Intermediate SensorThis sensor monitors the pressure inside the pressurized enclosure. It senses when the pressure is drops and provides early warning before the low pressure sensor trips the system. The setting on this is user selectable.

Electronic Purge TimerWhen both the enclosure pressure and the purge flow rate are correct, the Purge Flow Sensor activates the timer and the electronic timer starts. The timing period is selected using switches mounted on the timer module.

Note: Setting the timer to 00 minutes will cause infinite purging; the cycle will never complete.During timing, the percentage of the purge cycle is indicated by four LEDs which flashes sequentially while the timer is running.

The Electronic Timer contains an intrinsically safe battery pack that needs regular replacement. See Commissioning section.

Purge Complete ValveThis valve receives a signal from the purge timer that indicates the completion of the purge cycle and verifies that the pressurization signal is still present. If both conditions are satisfied a signal is sent to indicate that the purge is complete. This performs two functions: to turn on the electrical supply to the pressurized enclosure and to reduce the high purge flow rate to leakage compensation mode. It also provides a hold-on signal that maintains the leakage compensation mode with the power switch on, even when the purge timer has reset ready for the next purge cycle.

OR GateThis device provides the Purge Complete Valve with the hold-on function referred to previously. When either the timed-out signal or the purge complete signal is present it allows the pilot signal to be sent to the purge complete valve.

Alarm Only Circuit (/AO)If the pressure in the pressurized enclosure is too low the system will normally cut off electrical power to it. In certain circumstances, where local codes of practice allow, the system can be altered to provide a hold-on circuit that will maintain the electrical power supply to the pressurized enclosure while also providing a pressure failure alarm. The user must respond to the alarm and either restore the pressure to the pressurized enclosure or otherwise make the installation safe; for example, cut off the electrical supply. The decision to use the Alarm Only facility, and the allowable length of time for non-pressurized operation, is the responsibility of the user.

Warning: It is potentially dangerous to energise the pressurized enclosure in an non-pressurized condition when it is known that there is potentially explosive gas or dust in the hazardous location.

Visual IndicatorsVisual indicators are fitted to provide status information to the operator.

* The Green / Black combination indicates normal operation of the pressurized enclosure after the initial purging cycle has been completed.

Power Interlock SwitchThis flameproof power switch is activated by the signal from the Purge Complete Valve. This activation can be used to turn on the electrical supply to the pressurized enclosure. The cable from the switch is terminated in the /PA terminal box.

Alarm / Pressurized SwitchThis flameproof switch is operated by the pressurized signal. It allows a remote electrical system status indicator to show either pressurized or a pressure failure alarm. The cable from the switch is terminated in the /PA terminal box.

System Purging Switch (Optional)This switch is operated by the purge flow signal that allows a remote electrical system status indicator to signal that the system is purging; sometimes referred to as purge in progress. The cable from the switch is terminated in the /PA terminal box.

Purge ValveThis changeover valve selects between purge air flow or leakage compensation. It is sized to allow sufficient air into the enclosure during purging based on: the specified air supply pressure range, the minimum specified purging outlet flow rate +10% and the expected leakage rate from the pressurized enclosure. At the end of the purge cycle, the purge valve closes in response to the “Purge Complete” signal; it remains in the closed position until the next purge cycle is initiated.

Purge Flow RestrictorThis valve restricts the purge flow to the minimum required flow rate. The Purge Flow Restrictor must be readjusted during commissioning.

CLAPS SensorThis sensor monitors the pressure within the pressurized enclosure and sends a control signal to the CLAPS Regulator. The normal running pressure must be determined prior to system start-up so that the CLAPS Sensor may be set to the level required to control the CLAPS Regulator.

CLAPS Regulator This is the regulator that controls the leakage compensation air flow into the enclosure after the purging is complete. It either increases or decreases the air flow into the enclosure as appropriate to maintain a stable running pressure. The CLAPS Regulator must be set at the time of commissioning.

Relief Valve UnitThe Relief Valve Unit allows the purge air to exit the enclosure safely via a built-in spark arrestor. This spark arrestor is designed to prevent the emission of arcs, sparks and incandescent particles produced within the pressurized enclosure.

Purge air passes through the Relief Valve Unit; the preset pressure differential across the appropriate orifice ensures that the purge flow sensor is activated once the selected purge flow has been attained.

During the purge cycle a pneumatic cylinder operates the Purge Outlet Valve that lets the air from inside the enclosure exhaust through the Relief Valve Unit. When the system changes to leakage compensation mode, the Purge Outlet Valve is closed and the enclosure sealed.

The Relief Valve Unit has an in-built relief valve. This is sized to ensure that, if the air supply pressure rises up from the specified maximum, the internal enclosure pressure will not exceed the specified maximum working pressure of the pressurized enclosure.

/PA Terminal BoxThe Terminal Box is increased safety (Ex e) certified and incorporates the terminal connection points for the alarm and interlock switches. All contacts provided are volt free (dry).

Cable entry methods (for example conduit or cable glands) must be certified to IECEx, ATEX or INMETRO standards. The main requirement is that IP66 (or better) ingress protection must be provided by use of seals or washers.

Section 6: Installation of the SystemThe MiniPurge® is designed for use under normal industrial conditions of ambient temperature, humidity and vibration. Please consult Expo before installing this equipment in conditions that may cause stresses beyond normal industrial conditions.The MiniPurge® system must be installed by a competent person in accordance with relevant standards, such as IEC / EN 60079-14, and any local codes of practice.

The MiniPurge® control unit should be installed either directly on, or close to the pressurized enclosure. It should be installed such that the system indicators and certification labels are in view.

All parts of the system carry a common serial number. If installing more than one system, ensure that this commonality is maintained within each system installed.

Relief Valve UnitTo achieve effective purging, the points where air enters and exits the pressurized enclosure should normally be at opposite ends of the enclosure. The RLV unit must be mounted vertically and there should be a minimum clearance of 300 mm (12") around the spark arrestor (purge outlet).

It is important that the interior and exterior of the spark arrestor is kept clean and debris is not allowed to accumulate; this might affect the calibration of the device. In particular the exterior of the spark arrestor should not be painted or blocked in any way.

Air Supply QualityThe MiniPurge® system should be connected to a protective gas supply, which is suitable for purging and pressurization.

The supply pipe connection to the MiniPurge® must be appropriate for the maximum input flow rate for the application.

The air supply must be regulated at a pressure less than the maximum stated inlet pressure.

ML511 | v12 Page10




The air supply must be: clean, non-flammable and from a non-hazardous location. The air should be of Instrument Air Quality. Although the purge control system will operate with lower air quality, its operational life will be adversely affected. The equipment that is being protected by the MiniPurge® may also suffer because of poor air quality.

With reference to BS ISO 8573-1: 2010, Instrument Air is typically specified as:

Particle Class 1

In each cubic metre of compressed air, the particulate count should not exceed 20,000 particles in the 0.1 to 0.5 micron size range, 400 particles in the 0.5 to 1 micron size range and 10 particles in the 1 to 5 micron size range.

Humidity or pressure dew point

The dew point, at line pressure, shall be at least 10 °C below the minimum local recorded ambient temperature at the plant site. In no case, should the dew point at line pressure exceed +3 °C.

Oil Class 2

In each cubic metre of compressed air, not more than 0.1mg of oil is allowed. This is a total level for liquid oil, oil aerosol and oil vapour.

When an inert gas is being used to supply the purge system, risk of asphyxiation exists. Refer to Application Suitability section.

Before connection of the air supply to the purge system, the supply pipe work should be flushed through with instrument quality air to remove any debris that may remain in the pipes. This must be carried out for at least 10 seconds for every meter of supply pipe.

Unless a supply shut-off valve has been fitted to the MiniPurge® system, an external shut-off valve with the same, or larger, thread size as the Control Unit inlet fitting should be fitted by the installer to prevent any restriction of purge flow.

The purge air from the MiniPurge® Control Unit should be piped within the pressurized enclosure to ensure purging of potential dead air spots.

The purge system is fitted with an internal regulator factory set to 3 bar feeding the logic.

Pipe WorkIf the MiniPurge® is not connected directly to the pressurized enclosure, pipe work and fittings used to connect the Control Unit to the pressurized enclosure should be either metallic or appropriate to the environment into which the system is installed. No valve may be fitted in any signal pipe connecting the Control Unit to the pressurized enclosure. This pipe work must be fitted in accordance with local codes of practice where relevant.

Multiple EnclosuresThis system is suitable for the purge and pressurization of the primary pressurized enclosure and its associated terminal boxes.

Provision and Installation of Alarm DevicesWhen the pressure inside the pressurized enclosure is above the minimum, the Minimum Pressure Sensor returns a positive (pressurized) signal causing the alarm indicator on the control unit to change from red to green.

Page11




E:[email protected]



When the pressure falls below the minimum permissible the positive (pressurized) signal is removed. This absence of signal indicates a low pressure alarm condition and causes the alarm indicator on the control unit to go from green to red.

There are volt free (dry) contacts available within the terminal box for remote usage.

The user must make use of this alarm facility in accordance with the local code of practice for Action on Pres-sure or Flow Failure. Most codes include the following recommendations:

• Zone 1 Installations: Alarm and Automatic Trip of Power.

• Zone 2 Installations: Alarm Only on pressure or flow failure with power being removed manually.

Power Supplies and their IsolationAll power entering the pressurized enclosure should have a means of isolation. This requirement also applies to any external power sources that are connected to the equipment such as volt-free (dry) contacts within the pressurized enclosure. This is commonly achieved using the Power Interlock Switch.

Power Interlock SwitchThis switch is a Double Pole Normally Open, double-break switch: it provides two independent contacts that should be connected in series and used to isolate the power. This can be achieved using switchgear or other suitable switching device. These contacts are terminated and accessible to the user in the Ex e terminal box.

It is the responsibility of the user to ensure that the switch is only operated within appropriate technical limits.

The switch must be replaced after any short circuit that occurs within the main circuit; the switch is a piece of encapsulated equipment and as such it is not possible to check the state of the contacts. Technical modifications to the switch are not permitted.

Prior to commissioning, check that the Ex e terminal box is clean, the connections have been made properly, the cables laid correctly and all screws in the terminals are secure.

In all cases the application and isolation of power must be controlled by the MiniPurge® system using the power interlock signal.

No switches are permitted between the power switch and the MiniPurge® system other than an authorized manual override circuit.

The safe use of this switch is the responsibility of the user, all electrical installations must conform to local codes of practice.

ExceptionPower to apparatus that is already suitable for use in hazardous locations need not be isolated by the MiniPurge® system.

Section 7: CommissioningCommissioning the SystemNote: The steps 11 and 15 to 21 represent detailed commissioning testsThe following equipment is needed for this process:• Continuity meter• Gauge manometer (0 to 200 mbarg)• Differential manometerIf, after commissioning, the system does not perform as expected, refer to the Fault Finding Section.Follow the steps as outlined:1. Check all connections and that the Relief Valve Unit is fitted correctly with an unobstructed path to the

purge exhaust.2. Close the Purge Flow Restrictor Valve.3. Fully open external supply shut-off valve where fitted.4. Check that the internal logic pressure gauge reads 2.5 barg / 36 psi / 250 kPag.5. Check that the pressure gauge on main air supply reads 4 barg / 60 psi / 400 kPag.6. Check that the Pressure Relief Valve is correctly set by disconnecting the minimum pressure sensing pipe

at the bulkhead fitting on the input to the MiniPurge®. This will disable all of the pressure sensors.• Using a 4 mm nylon tube, connect a manometer to the bulkhead fitting from which the minimum pressure sensing pipe was removed.• Open the Purge Flow Restrictor Valve very slowly, until the Pressure Relief Valve opens • Check the opening pressure is within calibration limits. • This test can be carried out several times to ensure repeatability and compliance.Refer to the Maintenance of the System section if the Relief Valve needs recalibrating.

7. Close the Purge Flow Restrictor Valve.8. Remove the manometer and reconnect the minimum pressure sensing pipe to the bulkhead fitting.9. Remove red plug from the top of the Minimum Pressure Sensor and connect a gauge manometer.10.Connect a differential manometer to the test points on the flow sensor.11.To check sensor calibration

• The internal pressure in the pressurized enclosure must be below Relief Valve lift off pressure and above the CLAPS pressure• At this time the pressurized indicator should be green.• gradually open Purge Flow Restrictor Valve until purging indicator flashes yellow.Note: For large volumes it may take a long time for the purge flow to start.• very slowly close Purge Flow Restrictor Valve until the purging indicator stops flashing yellow.• Take a reading from pressure gauge.

12.To set the purge flow rate:

• Turn on the compressed air to the MiniPurge®.• Gradually open the Purge Flow Restrictor Valve until the black / yellow indicator changes to yellow (flashing). • The flashing yellow indicator confirms the correct flow rate.• The differential pressure should be greater than 6.4 mbarg.

• The relief valve is supplied with different orifice plates for the specified flow rate. This orifice plate is held in position by two M3 screws and can easily be changed by removing the large cover plate from over the outlet valve assembly and screws.

Warning: When opening the Purge Flow Restrictor Valve, ensure the over pressure within the pres-surized enclosure does not exceed the pressure relief valve setting.13.The purge timer will start as soon as the Purging Indicator flashes yellow. Check that the time delay

between the indicator turning to yellow (flashing) and returning to black is not less than the minimum time required for complete purging of the pressurized enclosure. Times in excess of minimum are permitted.

14.After the purge has been completed, the Purge Valve will close and the air flow into the pressurized enclosure will be controlled by the CLAPS Regulator. The initial setting may be too high or too low.

15.Gradually turn the CLAPS Regulator anti-clockwise to reduce enclosure pressure.16.Reduce regulator until intermediate sensor causes contacts to open.17.Check the manometer on the minimum pressure sensor.18.Continue to reduce the CLAPS Regulator to test the minimum pressure sensor.19.To check operation of Minimum Pressure Sensor, check readings on manometer as system will

automatically re-purge when it reaches minimum pressure.20.While the system re-purges, return the CLAPS Regulator to the initial setting. 21.If minimum pressure is below the set point, refer to the Recalibration section22.If the setting is too high, continual rising and falling of the enclosure pressure will be seen as the CLAPS

Regulator automatically shuts off and reinstates the flow. The CLAPS Regulator should be adjusted to reduce the flow into the pressurized enclosure by turning the adjuster screw anti-clockwise.

23.If the initial setting is too low the CLAPS Regulator may not provide enough air flow causing a gradual decline in enclosure pressure. To increase the flow into the pressurized enclosure, adjust the CLAPS Regulator Relief Valve unit by turning the adjuster screw clockwise.

24.To test the CLAPS settings, create a leak in the system by removing a bolt or losening a gland plate in order to create a 15mm hole. Remember to replace bolt or retighten gland plate after testing.

25.The setting of the CLAPS Sensor is factory calibrated to the normal working pressure expected in the pressurized enclosure, typically 10 mbarg. The pressure in the pressurized enclosure should be stabilized as close as possible to this figure. This can be checked by a manometer attached to the minimum pressure sensor.

26.Remove the air supply to the system, remove all test equipment and replace all plugs.Normal OperationFor normal operation of the system, after commissioning has been carried out it is possible to turn the air supply valve on or off to start or stop the system. After this, the purge and pressurization sequence is automatic.

Section 8: Maintenance of the SystemGeneral maintenanceThe maintenance of the system outlined in this manual should be supplemented with any additional requirements set out in appropriate local codes of practice.The following checks should be carried out every 6 – 36 months dependent on environment according to IEC / EN 60079-17 • Tests outlined in the Detailed Commissioning section.• Ensure that the Relief Valve Unit is free from contamination prior to making any adjustment. To do this:

• Remove large cover plate using a 8 mm spanner (wrench).• Check that the interior and all components are clean and free from contamination.• Replace large cover plate.

• Check the condition of the air supply filter element. Clean or replace as necessary.Additional maintenance checksThe following additional checks are recommended at least every 3 years:Check that:• Apparatus is suitable for use in the hazardous location.• There are no unauthorised modifications.• The air supply is uncontaminated.• The interlocks and alarms function correctly.• Approval labels are legible and undamaged.• Adequate spares are carried.• The action on pressure failure is correct.

Maintenance of Electronic Timer

This should be carried out every 3 years.

• The intrinsically safe battery pack associated with the electronic timer should be replaced and the commissioning tests repeated.

• After the timing phase has elapsed, the battery may be hot-swapped in the hazardous location without affecting the operation of the MiniPurge® system

Re-calibration of the Relief Valve Unit

Warning

Incorrect adjustment of the Relief Valve Unit can lead to significant over pressure and result in damage to the enclosure.If maximum pressure setting is reached, stop adjustment and reduce the pressure.To perform the following adjustments, an 8 mm spanner (wrench) and a 2.5 mm hex key will be required.Ensure that the Relief Valve Unit is free from contamination prior to making any adjustment. To do this: • Remove large cover plate using a 8 mm spanner (wrench).• Check that the interior and all components are clean and free from contamination.• Replace large cover plateTo adjust the lift off pressure of the Relief Valve:• Attach test equipment as described in the Commissioning Section.

• Remove small cover plate.• Whilst holding the central adjustment screw in position using the hex key, loosen the retaining nut.• Adjust the hex key clockwise to increase, or anti-clockwise to reduce the lift off pressure.• Before testing, retighten the locking nut whilst holding the adjustment screw in place.• Carry out the commissioning tests to check the correct setting of the relief valve after adjustment.

• The adjustment is sensitive and it is recommended that a 1/4 turn (maximum) adjustments are applied between tests.

Re-calibration of the Pressure SensorsThe brass nozzle on the sensor is sealed into position using Loctite thread sealant. If the thread has seized up, remove to a safe area and heat slightly to soften prior to making any adjustment. This prevents potential damage to the brass of the nozzle.• Disconnect pipe work from the sensor, including pipe located below the sensor.• Remove sensor by unscrewing anti-clockwise.• The nozzle is located under the sensor.

• The adjustment is sensitive, turn the nozzle in 1/8 of a turn steps.• Turn clockwise to reduce the pressure setting and anti-clockwise to increase.• Replace sensor, screwing clockwise.• Reconnect all pipe work.

Section 9: Fault FindingGeneral InformationIf you are having problems that cannot be corrected using one of the methods described, please call Expo oryour supplier for further assistance. If the system is less than 12 months old, parts under warranty should bereturned to Expo for investigation. A full report of the fault and the system serial number should accompanythe parts.It is common for problems with the MiniPurge® system to be caused by contamination of the air supply withoil, water or dirt. To prevent these problems, the air supply must contain a dust filter and a water filter. Thiswill ensure that the air is instrument quality and protect both the purge system and the equipment beingpurged. This filtration system is not provided by Expo and must be sourced separately.Contamination can enter the system from a number of sources. To prevent this, it is essential that theprocedures described in the Installation section are carried out prior to first use of the system. Theseprocedures should also be carried out following any disconnection and re-connection of the pipe work. Failureto perform these procedures may cause damage to the system that will not be covered by the warranty.The system has been designed for ease of fault finding and many of the components fitted are plug-in orchassis mounted. Check components by substitution only after establishing that such action is necessary.Before carrying out the fault finding procedures, ensure that:• Both the main air pressure to the system and for Motor Purge Systems, the regulated pressure to the logic

manifold are as specified on the settings sheet.• Air pressure does not drop below the minimum supply pressure during purging; the majority of faults

reported are due to insufficient air supply during the purge cycle.

System purges correctly but trips and auto re-purges at the end of the purge time.This is a result of the pressure within the pressurized enclosure being below the minimum pressure sensor setting. The pressure can be checked using a manometer. The most common causes of this problem are outlined below.Fault Location Cause SolutionPressurized Enclosure There is debris on the face of the

Relief Valve disk held in place by the magnet.

• Remove debris and ensure RLV disk is clean.

Enclosure leaking excessively. • Ensure all doors and covers are closed and that all conduit and cable glands are properly sealed.

• Seal any other leaks.Pressure sensing tube damaged. • Replace tubing.

CLAPS Regulator The CLAPS Regulator setting is too low.

• Increase the setting of the CLAPS regulator to raise the pressure in the pressurized enclosure after purging.

• To do this, turn clockwise.MiniPurge® Control Unit the Minimum Pressure Sensor

setting has drifted above the CLAPS setting

The Minimum Pressure Sensor needs re-calibrating.

• Refer to Re-calibration of PressureSensors in the Maintenancesection

Relief Valve opens (continuously or intermittently)

System enters purging but purge indication does not occur

System begins purging but cycles fail to complete

Fault Location Cause SolutionPressurized Enclosure Enclosure pressure is too high

due to CLAPS Regulator being open to far.

Adjust the CLAPS Regulator.

Relief Valve Unit Debris on the Relief Valve disk allowing air to leak from the valve.

Remove Relief Valve cover and clean the valve disk.

Fault Location Cause SolutionAir Supply Insufficient flow rate due to

inadequate air supply pressure. Often due to pressure drop in the supply pipe.

Static pressure of 5 barg must bemaintained during purge• Check air supply pressure at the

inlet to the control unit. • Ensure that the supply pipe bore is

suitable for the flow ratePressurized Enclosure Excessive leakage from the

pressurized enclosure.• Check around the enclosure while

purging is taking place. • Total leakage at purge outlet valve

should not exceed 10% of purge flow sensor setting.

• Check for leakage down cables and conduit.

Pipe Work Tubing from Relief Valve flow sensing point not air tight.

• Ensure fitting nuts are tightened.• Check for tube damage.• Repair as necessary.

Relief Valve Unit Relief Valve opening during purge • Check enclosure pressure on start up is less than Relief Valve lift off pressure.

MiniPurge Control Unit Flow sensor setting incorrect • Check the pressure is correct on the flow sensor.

Fault Location Cause SolutionElectronic Timer Time set to 00 • Reset timer to correct purge

time.The intrinsically safe battery pack is discharged

• Replace as necessary .
