1 - General Description

These Float Operated switches use reed switches, where the electrical SPST contacts are contained within a hermetically sealed glass envelope. They are designed to be operated with the float moving vertically up and down. The encapsulated internal reed switch is operated by the movement of the float and cannot be serviced by the user. Should a failure occur the float switch should be returned to Cynergy3 Components for replacement or repair; no repairs should be carried out by the user.

Switching voltage max: 200Vac / 120Vdc

Please contact Cynergy3 Components for advice if your circuit is inductive or capacitive.

The figures shown are the maximum values, for a purely resistive load.

Switching current max: 0.4A

Reed switches are extremely reliable components, when used within their specified electrical rating, so please note the maximum electrical ratings:- Switching power max: 10VA

Minimum fluid SG: 0.80

These hazardous area switches are identified by typical part numbers FLPVAXXBXXX & FLPSAXXBXXX etc.

The electrical connections are made via a 300cm long cable at the top of the device.

All external surfaces of the device are manufactured from stainless steel grade 316L. The central stem contains the fully insulated wiring and reed switch(es), which is supported by silicone rubber within the stem.

These switches are designed for use in Zones 1 & 2

The unit is designed in accordance with the ATEX directive; for the relevant BS:EN standards, see the Declaration of Conformity supplied with the device. It is intended that the device will be fitted to the top or side of the tank being sensed.

Cynergy3 recommends that all TAV brand level switches, used for high level alarm and fitted with either SPST reed switches, are wired to break on rising level.

Installation

Appropriate devices are available to identify both short and open circuit conditions in the external wiring to the switch. Any assessment of the use and application of such devices should always be undertaken by a competent individual.

It is essential that any installation or maintenance work is carried out by a competent individual.

No adjustment can be made to these devices themselves. The cable gland/nut must not be opened/removed.

The user should ensure that no static build up occurs during installation, including in non metallic parts.

The device should be installed using a suitable gasket, which is compatible with the application fluids. Check that there are no leaks, following installation.

The switch should be checked, prior to any installation or adjustment, for any damage to the following items: float, switch stem and cable.

All installation and maintenance work should be assessed by a suitably competent individual with regard to the specific hazards presented by the local environment, to the relevant national codes of practice and the application of the Cynergy3 device.

There are no known hazardous materials contained within Cynergy3 float switches, when used as directed. Please request document WI-202 for details of materials used.

IMPORTANT SAFETY NOTES

WARNING - DO NOT CARRY OUT ANY WORK WITH THE DEVICE ENERGISED.

Hazardous Materials

WARNING - The user should not carry out any modification or fit any non approved parts, as this will invalidate the ATEX certification.

Devices that will be subjected to heavy vibration should be supported within the tank. Do not use these devices, where the vibration levels could exceed 3g horizontal, without consulting Cynergy3 Components.

Corrosion

These devices may only be used in pressure applications of up to 10barg which must not be exceeded. Do not carry out any modifications to the device.

Pressure Applications

These wetted parts of these devices are manufactured from stainless steel 316L. Ensure that the materials are compatible with the fluid(s) being measured. Contact Cynergy3 Components if in doubt about this.

Vibration

The end user must protect the system against overpressure and, before opening any pressure retaining joint, the pressure must be reduced to atmospheric. The fitting of flange mounted devices requires suitable pressure retaining bolting, with sufficient torque to meet the flange standard being used. The torque required for screwed entry devices will depend on the gaskets and sealant used, therefore enough torque should be applied to prevent system leakage. Please contact Cynergy3 Components, if in doubt about this.

No adjustment can be made to these devices themselves.

Cynergy3 recommends that the electrical connection, the switch action, the switch operating levels etc., should be checked and verified in writing by a competent individual.

If the device is to be transferred to another application, where the liquid density is lower than the one for which the switch was originally supplied, Cynergy3 recommends that the switch is tested for bouyancy, if necessary.

Setting or Re-setting

Cleaning and maintenance

Check that the float or floats are able to move freely on the stem, that the device is generally clean and the top and bottom stops are secure. If the cleaning material is hazardous, take all necessary precautions.

Please refer to sections 2 and 3, before starting any cleaning, inspection or maintenance.

Check the operating level of the device by mounting it safely with the stem vertical, connect a suitably safe multi-meter and immerse the stem in a container containing the a fluid of the same density as in the application, taking all necessary precautions. The float should move up the stem to the top stop, by which point the switch should have operated; if the switch fails to operate, the device must be returned to Cynergy3 for inspection and resetting or repair.

It is recommended that, every 3 years, the device is isolated from the supply and, after ensuring there is no pressure inside the tank, that the device is removed from the tank for cleaning and checking.

The user should ensure that no static build up occurs in the installation. Care should be taken, when cleaning non-metallic parts, if necessary wash in warm soapy water, rinse and allow to dry; .DO NOT RUB WITH A CLOTH

No other servicing or overhauls should be necessary during the life of the device.The device should be returned to Cynergy3 Components, if it is found to have failed to operate correctly.

13 DESCRIPTION OF EQUIPMENT

The FLPV and FLPS Float Switches are reed switch operated devices, the electrical SPST (single pole, single throw) contacts being contained within a hermetically sealed glass envelope. The reed switches are insulated with heat shrink sleeving and fully encapsulated within a tubular stem using silicone rubber.

The encapsulated reed switch is operated by a magnet carried within a float assembly that moves up and down the stem.

Maximum length of product is limited to 500 mm so no switching level may exceed this.

The equipment comprises reed switches operated by external floating magnet closing contacts, intended for use with voltages of up to 200 V AC/120 V DC, no greater than 0.4 A and a maximum permitted power value of 10 VA.

This product range is intended for use with any liquids that are not corrosive to stainless steel 316L, that have a minimum specific gravity of 0.80, a process temperature range of -20oC to +79oC and a maximum pressure of 10 barg.

This product range orporates an integral cable arrangement; it is supplied fully assembled and does not require the end user to open the enclosure during the life of the product.
