Dimmer modules

Each SP6 contains one electronics module and either six

standard or three double-height dimmer modules. Each SP12

contains one electronics module and either twelve standard or

six double-height dimmer modules. Sensor packs support

15A, 20A, 50A, or 100A dimmer modules in various combina-

tions. (Custom dimmer configurations are available by special

order.)

Except for 15A and 20A modules, which are interchangeable,

module slots are designed to accept only the size module

specified for that space. Do not attempt to insert a module

into a slot configured for a different size module.

❶

Dimmer module circuit breakers

On the left end of a dimmer module’s front panel are either

one or two circuit breakers (depending on whether the

module is single or dual). If the breaker switch is to the right,

the circuit is off or tripped. If the breaker switch is to the left,

the circuit is on.

❷

LEDs

All modules have an LED marked Signal on the right end of

the front panel. The Signal LED is on whenever the dimmer is

receiving control signal.

Sensor AF (Advanced Features) dimmer modules also have an

LED marked Output which is on whenever the dimmer has

an output voltage. Dual modules have two sets of LEDs.

Removing dimmer modules

To remove dimmer modules, open the door, then grasp the

center part of the face panel with both hands and pull.

To replace the module, insert it firmly until you feel it seat

securely. When the module is correctly seated, it should be

flush with the other dimmer modules.

Warning: Do not touch the AC power bus. If more than one

adjacent modules are removed, the AC bus is exposed.
