Contact Closure Outputs - GRX-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 GRX-CCO-8 terminal blocks will accept #16–#22 AWG wire. Use the appropriate wire gauge
for your application. Connect the GRX-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 GRX-CCO-8 according to how the OPTIONS switches are set (see
Set Options - Zone
Control
).
4.
Replace the cover when wiring is complete.
Contact Closure Outputs - GRX-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 GRX-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 GRX-CCO-8 terminal blocks will accept #16–#22 AWG wire. Use the appropriate wire gauge
for your application. Connect the GRX-CCO-8 and the MWT Controllers as shown in the diagram
at right.
Note:
The Common terminals must be tied together as shown.

Set Options
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 Control Method (Zone vs. Scene)
The GRX-CCO-8 may operate in one of two ways: Zone Control or Scene Control. In Zone Control,
the outputs of the GRX-CCO-8 are controlled by zones on a GRX Control Unit. Also, the outputs
may be set as MWT channels or individual outputs. See
Set Options – Zone Control
for further
description.
In Scene Control, a single output on the GRX-CCO-8 will be closed based on which scene is
selected on the GRX Control Unit. See
Set Options – Scene Control
for further description.
To operate in Zone Control, set Address Switch #5 to OFF. Proceed to
Set Number of MWT Groups
.
To operate the GRX-CCO-8 in Scene Control, set Address Switch #5 to ON. Proceed to
Set Options
– Scene Control
.
