Interlocks / Relay Board
Drawing No: CSP1000-5002 - Section 3
The mains input for the high voltage charger is routed via a contactor controlled from the relay
board located under the left side panel. A small mains transformer and rectifier provide 12VDC to
operate the contactor relay.
Mains to the transformer is connected via a micro switch situated on the left side panel. The micro
switch disconnects power to the transformer when the top cover is removed. With the cover off,
the charger has no mains power connected.
TO ENSURE CORRECT OPERATION OF THE POWER SUPPLY, THE TOP COVER MUST BE
SECURED IN PLACE. A special 20mm hex screw is provided to operate the micro switch, THE
20MM SCREW NEEDS TO BE PLACED IN THE FRONT POSITION ON THE TOP LEFT HAND
SIDE OF THE UNIT.
FAILURE TO SECURE THE COVER USING THE 20MM SCREW WILL RESULT IN A FAULT
CONDITION ON THE FRONT PANEL OF THE POWER SUPPLY!
The 12VDC output from the rectifier is connected to the relay via an interlock on the high voltage
socket. With the high voltage connector removed or disconnected, the relay is de-energised,
disconnecting mains power to the charger.
FOR CORRECT OPERATION OF THE POWER SUPPLY, THE HIGH VOLTAGE CONNECTOR
MUST BE FITTED AND TOP COVER SCREWED DOWN.
If the top cover or high voltage connector is left off, the FAULT and INTERLOCK LEDs will
illuminate on the CSP front panel, resetting the system.
A second contactor relay will disconnect mains power to the high voltage charger, if a problem
occurs in the 12VDC logic supply to the control and front panel boards.
