Circuit Breakers
Mains Supply Circuit Breaker
The Mains Supply is protected by a thermally operated circuit breaker, which can be
manually reset. This circuit breaker is located in a metal enclosure together with the main
supply switch.
Should this device trip, firstly ascertain the cause of the fault and rectify. To reset the
device, simply depress the yellow centre back into the body of the circuit breaker.
Motor Fuse
The Motor fuse is located on the motor control PCB (located within top sign No.1 – see
‘Access section’). This fuse is designed to protect the motor control circuitry and must only
be replaced with an identical item. Failure of this fuse would normally indicate a motor
fault.

Power Supplies
For each set of back-to-back player sections, there is a power supply unit (PSU) and
Dichroic lighting transformer. These both have circuit breakers fitted in the low voltage
sides of the circuits. These circuit breakers are physically mounted within the metal
enclosures of these units, and the reset buttons are easily accessible without opening the
units.

The circuit breakers provide protection for the circuit cabling etc. In most instances of a
fault condition occurring, the switch-mode power supply will fold-back within a fraction of a
second to near zero. Removal of the fault allows the supplies to re-establish. Should a
circuit breaker trip, reset is achieved by pressing the protruding white button back into the
device body.
