Contact Closure Outputs - OMX-CCO-8 to A/V Equipment
1.
Refer to the A/V equipment installation guide to determine which contact to wire, normally open
(NO) or normally closed (NC). The diagram below shows wiring with normally open contacts.
2.
The OMX-CCO-8 terminal blocks will accept #16–#22 AWG wire. Use the appropriate wire
gauge for your application. Connect the OMX-CCO-8 and the A/V Equipment as shown in the
diagram below.
3.
After wiring, use the manual override buttons to verify proper system operation. Press the but-
ton associated with the desired output to close the relay. The manual override buttons operate
the OMX-CCO-8 according to how the OPTIONS switches are set (see
Set Operation of MWT
Channel(s) or Individual Outputs).
4.
Replace the cover when wiring is complete.
Contact Closure Outputs - OMX-CCO-8 to MWT Controllers
Note:
The number of MWT channels and the number of outputs per MWT channel must be set.
This will affect how the OMX-CCO-8 is wired. Refer to
Set Options
for more information.
1.
Refer to the manufacturer’s MWT Controller installation guide to determine which contacts to
wire, normally open (NO) or normally closed (NC). The diagram at right shows wiring with nor-
mally open (NO) contacts.
2.
The OMX-CCO-8 terminal blocks will accept #16–#22 AWG wire. Use the appropriate wire
gauge for your application. Connect the OMX-CCO-8 and the MWT Controllers as shown in the
diagram at right. This diagram shows an MWT with two relays per channel.
Note:
The Common terminals must be tied together as shown.
3.
After wiring, use the manual override buttons to verify proper system operation. Press the but-
ton associated with the desired output to close the relay. The manual override buttons operate
the OMX-CCO-8 according to how the OPTIONS switches are set (see

Warning!
When controlling MWTs, the GRX-CCO-8 can be set up to have both OPEN and
CLOSE outputs closed simultaneously. Some MWT controllers cannot have both OPEN and
CLOSE inputs closed simultaneously, as this will damage the motor. Refer to your MWT
controller’s installation guide to make certain that the GRX-CCO-8 is set up properly for
your MWT controller.
Set Number of MWT Channels
The number of MWT channels may be set from 0 to 4. If the OMX-CCO-8 will not be controlling
any MWTs, set the number of channels to 0.
Set the number of channels using switches 1, 2, and 3 on the OPTIONS switch (see diagram
below).
