Contact Closure Input Control WiringThe WC-2M-GC and WC-4M-GC accept Class 2, drycontact closure inputs. The contact closure inputs for thisunit may be either momentary or maintained. The contactclosure type selected using the Options switch #5 (OFF =Momentary, ON = Maintained). Momentary dry contactclosure inputs require a minimum closure time of 0.2seconds.

The contact closure device must be able to switch 2 mAat 30 Vdc. If multiple channels or Group Controllers arewired in parallel to one contact closure, the contactclosure device must be rated for the total current of all thechannels or Group Controllers wired together (totalcurrent = 2 mA times the number of Group Controllers orchannels in parallel). Example, if you connect 4 GroupControllers in parallel, the contact closure device wouldneed to be rated for at least 8 mA, at 30 Vdc.

Configuring the Motor Direction for theOpen and Close FunctionsFor each Channel of the unit, the motor’s direction ofrotation needs to be configured for the Open and Closefunctions so that the AC Motor will move in the properdirection. This is accomplished using the OptionsSwitches, #1 through #4. This step needs to be performedwhether each channel is controlled individually or allchannels are controlled together.

1. Restore power to unit. Once the appropriate linevoltage and motor connections have been made to theunit, replace the cover on the line voltage wiringcompartment. Remove the cover from the Class 2wiring compartment. Turn power back ON.

2. Determine AC motor position. Determine whetherthe AC Motor that is controlled by Channel 1 is openor closed. If it is open, press the Close 1 manualoverride button. If it is closed, press the Open 1manual override button. If the AC Motor moves to thedesired position, the Channel is configured properly.Proceed to Step 4. If the AC Motor does not move tothe desired position, proceed to Step 3.

3. Verify motor movement. If the AC Motor did notmove to the desired position in the prior step, slide theOptions Switch #1 to the opposite position. Press thesame button again that was pressed in Step 2 (Openor Close). If the AC Motor moves to the desiredposition Channel 1 is now configured properly.Proceed to Step 4.

4. Repeat for remaining motors. Repeat Steps 2 and 3for the rest of the Channels that are connected to ACMotors. Options Switch #2 configures Channel 2,Options Switch #3 configures Channel 3*, and OptionsSwitch #4 configures Channel 4*.

Each motor channel has a contact closure input terminalblock. In addition, the unit has a master control contactclosure input terminal block. The master control contactclosure input will operate all four motor channelssimultaneously. See the wiring diagrams on pages 10–11.

The stop function can be achieved either by providing acontact closure input to the stop terminal of the inputterminal block, or by simultaneously providing a closureon the open and close terminals of the input terminalblock. Both stop methods will be addressed in the wiringdiagrams on pages 8–11.

Setting the Contact Closure Input TypeWhen operating from contact closure inputs, the WC-2M-GC and WC-4M-GC can accept either momentary ormaintained contact closure inputs. See Appendix A onpage 13 for a more detailed description

Momentary Inputs: The unit will accept a momentaryclosure input of greater than 0.2 seconds to activate thedesired function, i.e. raise, lower, or stop. The powerrelays will open 2 minutes after either the open or closecontact closure is received, or when another contactclosure is received, whichever comes first. The relays willopen immediately upon receiving the stop contactclosure.

Maintained Inputs: The power relays remain closed aslong as the input closure remains closed. However, themost recent command received will be executed even ifthe previous contact closure is still maintained.

Momentary or maintained inputs are selected usingOptions switch #5. In the ON position, maintained modeis selected. In the OFF position, momentary operation isselected.

Contact Closure Inputs:Maintained Mode OperationIn maintained mode, the Switched Live output for achannel, for instance SW Live 1A, is energized only whilethe contact closure is provided to the input for thatchannel. As soon as the contact closure is removed fromthe input, the Switched Live output is de-energized. Thisgives rise to possible conflicts if a contact closure isprovided during the time another contact closure isprovided. Below are descriptions of how the GroupController addresses these situations.

Inputs on a single channelWhen a contact closure is provided to a single input on anindividual channel, the Group Controller will energize theappropriate Switched Live output. If a contact closure isthen provided to another input on that same channel whilethe first contact closure is provided, the Group Controllerwill recognize this combination as a request to stop. Thiswill happen regardless of how much time elapses betweenthe application of the two contact closure inputs.

For example, if a contact closure is provided to Close 1,the Group Controller will energize the Switched Liveoutput to close the AC motor on Channel 1. If a contactclosure is provided to Open 1 while a contact closure isstill provided to Close 1, the Group Controller will de-energize the Switched Live output on Channel 1, stoppingthe AC motor.

If contact closures are provided to both the Open andClose inputs on a particular channel, the Group Controllerwill de-energize the Switched Live outputs for thatchannel. If one of the contact closures is then released,the Group Controller will NOT recognize that as a requestto move the AC motor to the position indicated by thecontact closure that is still provided. Instead, the GroupController will leave the Switched Live outputs de-energized. In order for the Group Controller to recognize anew input signal, the contact closure must be removedand then provided again.

Note: It is not recommended to connect two or morecontact closure devices on the same channel ifMomentary mode is selected. If this is done, it is possiblefor a channel to become unresponsive to inputs if contactclosures are provided by the two devices at the sametime.

For instance, if one device provides a contact closure tothe Open input, the Group Controller energizes theSwitched Live output that opens the AC motor. If thesecond device then provides a contact closure to theClose input, the Group Controller will then de-energize theSwitched Live output, stopping the AC motor. At this point,both contact closures must be removed before the GroupController will recognize a new request.

If it is desired to connect two or more contact closuredevices on the same channel, use Maintained mode.

Inputs on a single channel and Master ControlWhen a contact closure is provided to a single input on anindividual channel, the Group Controller will energize theappropriate Switched Live output. If a contact closure isthen provided to a Master Control input while the firstcontact closure is still provided, the Group Controller willenergize the Switched Live outputs requested by theMaster function on all channels of the Group Controller.

For example, if a contact closure is provided to Close 1,the Group Controller will energize the Switched Liveoutput to close the AC motor on Channel 1. If a contactclosure is then provided to the Master Open input while acontact closure is still provided to the Close 1 input, theGroup Controller will energize the Switched Live outputsto open the AC motor on all channels.

When a contact closure is provided to a Master Controlinput, the Group Controller will energize the appropriateSwitched Live outputs on all channels of the GroupController. If a contact closure is then provided to a singleinput on an individual channel while the Master Controlcontact closure is still provided, the Group Controller willactivate the Switched Live output requested by theindividual input, while keeping the Switched Live output inthe same state for the other three channels.

For example if a contact closure is provided to the MasterOpen input, the Group Controller will energize theSwitched Live outputs to open the AC motor on allchannels. If a contact closure is then provided to theClose 1 input, the Group Controller will energize theSwitched Live output on Channel 1 to close the AC motoron Channel 1, but continue energizing the Switched Liveoutputs on Channels 2, 3 and 4
