Removing 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.

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 pack is
receiving DMX512 input.
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.
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.
