Description The GP200 ACM (auxiliary control module) is used in ATS melter systemsthat include a GP200 metering pump. Figure 2 shows the key parts of theGP200 ACM.

An ACM is a distributed control module that is used in ATS melter systemsin either or both of the following situations:

� when the system needs additional temperature control zones to heatexternal components, such as applicators or hoses

� when the system has metering applicators and/or metering stationsthat require motor control (such as the GP200 metering pump)

This distributed control philosophy allows standardization of the ATS melterwhile also allowing the flexibility to add additional temperature control zonesand motor controls to a melter system. The GP200 ACM is connected to theATS melter via a standard Allen-Bradley network cable.

Prevent Electrical Noise To ensure that the equipment will operate as intended, follow theseguidelines when routing cables, cordsets, and wiring:

� Verify that all equipment is properly grounded.

� Keep all wire-runs and cabling as short as possible.

� Avoid running wires parallel to conductors that carry high current,especially in the same conduit or wire trough.

� Avoid routing wiring and cables close to brush-type motors.

Connect the Temperature Control Zones Connecting temperature control zones typically involves the following:

� connecting hose cordsets to the ACM via extension cables orthrough a junction box

� connecting pressure-fed applicator cordsets to the ACM viaextension cables or through a junction box

� connecting the GP200 metering pump heater and sensor cables tothe ACM

An ATS melter system is typically shipped with many of the cables you willneed to make these connections.

Because ACMs are configurable, the way temperature control zones can beconnected to them varies greatly. Accordingly, this section providesinformation that applies only to the most typical installations. Contact yourNordson representative as needed for assistance in installing your ACMsuch that your individual needs are met. In general, the way temperaturecontrol zones are connected to an ACM depends on the following:

� the type of connectors on the ACM� whether a junction box will be used

The connectors on the ACM may be exactly like the electrical connectors onthe ATS melter, in which case the heater and sensor control are combinedinto one cordset or splitter/extension cable, or the ACM may have individualconnectors for heater and sensor control. The most important thing aboutconnecting temperature control zones is ensuring that heater and sensorwiring is connected to the correct termination points in the junction box (ifused) and ACM. Figure 6 shows a typical ATS melter/GP200 ACMinstallation configuration. Please note that your installation configurationmay differ significantly depending on the configuration of your ACM and thespecifics of your application.

Connect the Temperature Control Zones (contd)

Follow this general procedure to connect temperature control zones to theACM. Contact your Nordson representative for assistance as needed.

1. Ensure that the total wattage to be connected to the ACM will notexceed 16,000 W.

NOTE: Each ACM temperature control zone can supply 2,000 W, butthe total wattage supplied is limited to 16,000 W in order to keep theswitchgear sizes the same.

2. If your ACM has hose/applicator electrical connectors (like the ones onthe ATS melter) that combine heater and sensor wiring into one cable,connect your additional temperature control zones directly to the ACMvia splitter and/or extension cables. Refer to the melter and applicatormanuals for the part numbers of splitter and extension cables that canbe used with hose and applicator cordsets.

3. If you are connecting temperature control zones for a metering pumpthat requires a junction box, follow these steps:

a. Connect the heater and sensor wiring from the metering pump to thejunction box. Refer to the metering pump manual as needed.

b. Connect the ACM heater and sensor cables to the junction box.

c. Connect the ACM heater and sensor cables to the heater andsensor connectors on the ACM.

NOTE: The heater and sensor connectors are located on thebottom of the junction box. The heater connector is usually labeledCONTROL and the sensor connector is usually labeled RTD.

4. Refer to Record of ACM Zones at the end of this section to record thenumbers and names of the ACM temperature control zones youconnected.

Setup When a hot melt system includes an ACM, the operator interface on themelter includes additional menus and screens for the setup and operation ofthe ACM. These menus and screens are very similar to the menus andscreens for the melter in the way they look and work. For example, a melterwith an ACM will have an ACM Temperature Control screen in addition to amelter Temperature Control screen. The primary difference between the twoscreens is that the melter Temperature Control screen is used to set melterzone temperatures while the ACM Temperature Control screen is used toset the temperatures of the zones connected to the ACM. With theexception that the zone names are different, all of the ACM screens andmenus are nearly identical to the corresponding melter screens and menus.

This section explains how to set up the melter control system prior tooperation of the ACM and how to change the settings at any time. It isorganized as follows:

� Common Procedures� Setup of the Temperature Control System� Setup of the GP200 Metering Pumps

For information about how to operate the ACM, refer to the next section,Operation.

NOTE: Nordson gives you the option of two different operator interfaces:PanelMate or PanelView. In most of the screen illustrations, sample screensfrom a system with the PanelMate interface are used, but the PanelViewscreens are similar in appearance and function. If your melter has anoperator interface other than PanelMate or PanelView, contact yourNordson representative as needed for assistance in setting up the controlsystem.

GP200 ACM 31


Entering a Temperature Offset Follow this procedure if you want to enter a temperature offset for one ormore temperature zones in your system.

Explanation

In some temperature zones, the temperature of the adhesive (or, in somecases, of the air) may rise or fall significantly between the point wheretemperature is sensed and the point where the material is applied. Thetemperature offset feature gives you a way to compensate for thisdifference. For example, if want an application temperature of 200 �C (392�F) and you are losing 5 �C (9 �F) between the point of sensing and thepoint of application, you can enter a minus 5 �C (minus 9 �F) for the offset.The system subtracts this number of degrees from the temperaturefeedback from the sensor, causing the zone to be heated approximately5 �C (9 �F) higher than the setpoint temperature of 200 �C (392 �F). As aresult, the air will exit at the application point close to the desired applicationtemperature of 200 �C (392 �F).

Procedure 1. Determine the name or number of each air temperature zone you want

to enter a temperature offset for. Refer to Determining Zone Names andNumbers earlier in this section.

2. Determine the setting you want for each zone. Refer to Table 7 for thedefault setting and the range of settings.

Setting Up Temperature Setback Follow this procedure to set up the temperature setback feature. Tomanually enter or exit the setback mode, refer to Entering and Exiting theSetback Mode in the operation section of the melter manual.

Explanation

The temperature setback feature is designed to prevent char formation andto conserve energy during breaks in production. When the system entersthe setback mode, it drops the temperature of each enabled zone by thesetback amount (the number of degrees previously entered) and then keepseach zone at the reduced temperature. Setback can be applied to all zonesor just to selected individual zones.

The system can be placed in the setback mode in two different ways: eitherthrough immediate setback or through automatic setback. Immediatesetback occurs when an operator manually places the system in thesetback mode through the Startup and Setback Control screen. Automaticsetback occurs when the pumps have remained inactive for theuser-specified amount of time and the system activates the setback mode.

The system can also exit the setback mode in different ways. When thesystem is in immediate setback, an operator can remove the system fromthe setback mode, or the system can automatically exit setback mode afterthe pumps have remained inactive for the user-specified amount of time.When the system is in automatic setback, an operator must always removethe system from the setback mode through the Startup and Setback Controlscreen.

If the system is in the setback mode when automatic startup occurs, it willautomatically exit the setback mode and return the zones to their normaloperating setpoints.

Procedure 1. Determine the name or number of each zone you want to enter setback

values for. Refer to Determining Zone Names and Numbers earlier inthis section.

2. Determine the setback settings you want to enter. Refer to Table 10 forthe default settings and the range of settings.

Setting PID Values Follow this procedure to set PID (proportional/integral/derivative) values forACM zones. To set PID values for melter zones, refer to Setting PID Valuesin the setup section of the melter manual.

Explanation

The melter is shipped with default PID values that will work well for most, ifnot all, temperature zones. Nordson recommends that you do not changethe PID values unless you encounter a temperature control problem for oneor more zones. If you have experience in PID tuning, you can use thisprocedure to change the values.

The following procedure assumes that you already know the PID values youwant to enter.

Procedure 1. Determine the name or number of each zone you want to enter new PID

values for. Refer to Determining Zone Names and Numbers earlier inthis section.

Setup of the GP200 Metering Pumps Follow this procedure to set up the GP200 metering pumps, which includessetting the pump speeds and setting up the pumps for key-to-line control. Toset up the melter pumps, refer to the melter manual.

Explanation This explanation and procedure describe one of several ways to set up thepumps. In this method, you enter the pump speed that provides the desiredamount of adhesive output when your production line is running at yourmaximum line speed setting. To calculate this pump speed, you need thefollowing information:

� the desired pump output in grams/minute (based upon the add-onweight for the application)

� the density of the adhesive

� the pump rating in cc/revolution/stream (where the number ofstreams is one or two)

EXAMPLE: Suppose that you are using an adhesive with a specific gravityof 0.96 g/cc and you want an output of 200 g/min using a single-streampump with a capacity of 2.4 cc/rev. You would use the following equation tofind the required pump rpm:

rpm = desired output x specific gravity ÷ pump capacity

rpm = 200 g/min x 0.96 g/cc ÷ 2.4 cc/rev

rpm = 80 rpm

The output you calculate is referred to as the Maximum RPM setting for thepump. This setting, together with the Minimum RPM setting, determines thepump curve for your system. Figure 21 shows a typical pump curve with aMaximum RPM setting of 80 rpm and a Minimum RPM setting of 0 rpm.Figure 21 also shows how you can change the pump speed by changing theAuto Ratio setting.

If you want a pump to turn slowly when the line stops or jogs at a reducedspeed, you must enter a Minimum Speed greater than 0 and keep the runcommand active. If you do this, the pump curve changes. How it changesdepends upon the type of system you have. Figure 22 shows the twodifferent pump curves when a Minimum Speed setting greater than 0 isentered. Your system has the standard pump curve (shown on the left)unless you requested the optional pump curve (shown on the right).

CAUTION: If your GP200 metering pump does not have mechanicalpressure relief functionality, do not run the system with a minimum pumpspeed setting above 0 RPM.

NOTE: GP200 metering pumps should not be operated unless thedispensing modules on the corresponding applicator are open.

GP200 ACM 45


An alternate method of setting up the pumps is to just enter the maximumpossible pump speed and then adjust the pump speed using the Auto Ratiobutton on the Motor Control screen to obtain the desired output. In thismethod you rely on estimation, observation, and measurement of output todetermine the ratio percentage that gives you the desired output.

7. Press the appropriate Minimum RPM button and enter the desiredpump speed as the production line slows down to a stop (or runs at agreatly reduced speed). If you want the pump to stop when the linestops, make sure that the setting is 0 rpm. The button display updates toshow the new entry.

NOTE: If your melter is equipped with a PanelView touchscreen, enteran rpm that is 10 times the desired minimum rpm. For example, if youwant a minimum pump speed of 10 rpm, enter 100.

8. Repeat steps 5 through 7 for each pump in your melter.

9. Press Maximum Line Speed or Line Speed at 10 VDC, whicheverappears on your screen.

10. Enter the appropriate information for line-speed reference.

Button You Pressedin Step 9 Procedure

Maximum line speed(digital input)

Enter the maximum reference thatcorresponds to your production rate when theline is running at its maximum operatingspeed.

EXAMPLES: If your production rate is 250products per minute when operating at amaximum line speed of 300 meters perminute, you would enter 250 if your referenceis provided in products per minute or 300 if it isprovided in meters per minute.

Line speed at 10 VDC(analog input)

Enter the percentage of your operating linespeed that it would take to produce a 10 VDCsignal.

EXAMPLE: If your line-speed reference deviceprovides a 5 VDC signal when your line isrunning at its maximum operating speed(100%), the line would have to run at 200% ofthe maximum to speed to cause the device toproduce a 10 VDC signal, so you would enter200.

Setup of the Melter Pump Pressure The adhesive output to the GP200 metering pump must be at a particularpressure regardless of flow, so one pump of the ATS melter will bededicated to supplying the metering pump with adhesive. Follow thisprocedure to enter a pressure setpoint for this pump.

Explanation When in the automatic mode, the ATS melter pump (hereafter referred to aspump x) dedicated to supplying the GP200 metering pump at a particularpressure operates in a closed-loop pressure-feedback mode, which meansit will not follow the line-speed reference signal. The pressure transducerthat provides the pressure feedback is located on the GP200 meteringpump and is factory-configured for each individual ATS melter system.

When pump x is running in the closed-loop pressure-feedback mode, thecontrol system will generate alarms to warn the operator if the pressure istoo low. When the motor is at 100% of rated speed for 2 minutes, a warningappears on the Last 10 Alarms screen. If this warning is not acknowledgedwithin 10 minutes, all melter motors and any auxiliary equipment will shutdown. The warning text is as follows:

ATS Motor 1 PID LaggingATS Motor 2 PID LaggingATS Motor 3 PID LaggingATS Motor 4 PID Lagging

If necessary, the pump pressure PID settings can be adjusted. However,these settings are not accessible from the operator touchscreen�anychanges to the pump pressure PID values must be made while online to thePLC.

When in the manual mode, pump x uses the manual mode rpm setting, thusoperating like the other melter pumps.

NOTE: When all heating zones are near their setpoint temperatures,the Heat Status will change from �Not Ready� to �System Ready�(except when a startup delay is set). When the system reaches theready state, the pumps can be started.

NOTE: The temperatures of all zones must be above the setpointoperating temperature minus the low-fault-delta setting before thesystem will enter the ready state.

NOTE: If your system is set up to use the startup delay feature, theHeat Status will not change to �Ready� as the zones are nearing theirsetpoint temperatures. The system delays entering the ready state untila user-specified period of time has passed. This additional heating timegives the adhesive in the system sufficient time to melt before you startthe pumps. For information on setting up this feature, refer to Setting UpStartup Delay in the Setup section of the melter manual.
