Set Number of MWT Channels (Zone Control Only)
If the Control Method is set to Scene Control, refer to
Set Options – Scene Control
.
The number of MWT channels may be set from 0 to 4. If the GRX-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).
Set Options – Zone Control
■
Set the OPTIONS switches to select the operating mode that is appropriate for your application.
■
The outputs may be set to either all momentary or all maintained.
■
The MWT channel(s) may be set to have Open and Close outputs, or Open, Stop and Close out-
puts. Refer to the manufacturer’s MWT Controller Installation Guide to determine how many out-
puts per MWT channel are appropriate.
■
Set the appropriate Stop function. Refer to the manufacturer’s MWT Controller Installation Guide.
■
Outputs not used as MWT channels may be controlled as individual outputs (e.g., if the GRX-
CCO-8 is set to have 2 channels of MWT controllers, and each channel has 2 outputs, then
there will be 4 outputs left over to act as individual outputs). The output will be closed when the
GRX Control Unit zone to which it is assigned has an intensity greater than zero.
* Please refer to
Warning
at the beginning of
Set Options
section.
Note:
If channels are configured to have three outputs per MWT channel, then the maximum
number of MWT channels is two.
Set Options – Scene Control
■
Set the OPTIONS switches to select the GRX Control Unit scene range that is appropriate for
your application. See the chart on the next page.
■
Set which scene applies which outputs. Only one output may be closed at any given time.
