Section 3:
Programming the Circuit Selector
Before proceeding, you must have one or more of the following: preassigned setup, knowledge of how the system
is to operate, plans and specifications from owner's representative on how the system is to be set up, or owner or
owner's representative present.
Circuit Selector Functions
There is a circuit selector in every lighting control panel. It is used to
communicate with GRX-4000 Series control unit(s) or DMX512 stageboards
– and then to tell the dimmers their intensity levels. It is also used to select
Values for each circuit:
• Circuit Level - allows a way to view the intensity being sent to the dimmer
or manually take over control of the dimmer's output. See description in the
Troubleshooting section.
• Load Type - to be changed to match the load to the Load Type value. Non-
Dim 4 must be used if the Load is not dimmable.
• Control and Zone Assigned - allows two ways of assigning a control and
zone to a specific circuit.
1. ' w/ Circuit Schedule' allows a Control and Zone (such as 'A2','3') to be
directly entered into the Circuit Selector.
2. ' w/ Zone Capture' allows a Control and Zone to be 'captured' by the
Circuit Selector by doing the following:
A.
P ress and hold buttons 1 and 5 until the Select Value LED lights.
B.
P ress button 5 repeatedly until the Zone Capture LED lights. The
circuit will now flash.
C.
U se buttons 1 and 2 to choose the correct circuit to be assigned.
D.
G o to the GRX-4000 Series control unit to be assigned to this

E.

F.
I dentify the zone to be assigned to this circuit.
G.
P ress the zone 6 button until all zone LEDs are off.
H.
P ress the zone 5 button until the load starts tracking the zone
intensity LEDs.
I.
P ress the zone 6 button until all zone LEDs are off.
(Steps H. and I. must take less than 15 seconds or the circuit
selector will not lock on the captured zone.)
J.
G o back to the Circuit Selector and the proper control and zone
should be displayed. Repeat this process for any other circuits.
K.
P ress and hold buttons 1 and 5 until the VIEW VALUE LED lights.
• Low and High End trims - allows the circuit's range limits to be adjusted.
• The Value window will display the software revision level of the circuit
selector 20 minutes after the last button press.
Set Normal/Emergency Switch
Note: This step is only performed if there are any panels with Emergency
(Essential) lighting circuits on the job. Panels are shipped with switch 6
(located at the base of each circuit selector) in the center position for normal
operation (without any Emergency/Essential lighting circuits). When switch 6
is in its center position (as shipped), terminal 5 has no affect on the circuit
selector operation.
1. Identify a panel supplied with Normal (Non-Essential) power. Move its switch 6
to the left position.
2. For all the Emergency (Essential) lighting panels, move switch 6 to the right
position.
In this arrangement, the Emergency (Essential) Lighting panel will "sense" the
Normal (Non-Essential) panel's power. When Normal (Non-Essential) power
is removed, the Emergency (Essential) lighting will go to 'ord' override levels
(factory set to 100%).
Notes
• If there is no Normal panel, contact Lutron Technical Support.
• Override ('ord') Level is factory set to full output (100). If less than full output is needed, contact Lutron.
• Loss of Normal (Non-Essential) power can be simulated by turning off all connected Normal (Non-Essential) panel's
control breaker.
