Interconnect Cables: There are five interconnect cables in the power supply chassis that make
connection between the circuit boards and the circuit boards and the jacks on the rear panel.
Make sure they are in place and making connection.
There are two shield ribbon cables connecting between the power supply chassis and the control.
Make sure the connections are in place and bolted in position.
There are three cables that connect to each transformer module. Make sure the cables are screwed
tight and make a secure connection.
5.2 Turn On
(A) With house power present at TB-1 on the rear panel of the power supply, turn on all circuit
breakers.
The PWR OK light on the power supply chassis should be illuminated. If not illuminated,
check the following:
CHECK:
Rear Panel Circuit Breakers
Fuses on the 24V Control Supply Assembly
Fuse on the regulator circuit board
The power supply cooling fan should be ON. The 24 volt
control power should be present throughout the system.
(B) High Voltage Control Panel (If Used):
The power light should be illuminated
The 24V control power should be present
Check item (A) and interconnect between the power supply and control assembly ribbon
cables.
The DOORS light will be illuminated with interlock chain closed.
CHECK:
Turn On key switch
Temperature switch below 170oF
External Interlock J110 Pins C-D Jumpered
Emergency OFF push-button active "Rotate"
Transformer Module cover closed
The green light in the HV OFF switch should be illuminated
HV READY FOR TURN ON
(C) H.V. ON (Using the optional Control Panel):
The high voltage ON function requires the ready light in the HV OFF switch to be
illuminated. Check the items in (B) for a High Voltage Ready.
The HV ON function is a multi-sequence turn ON. Pressing the ON push-button energizes a
relay on the power card that slowly charges the rail capacitors. If the capacitors do not
charge in approximately 50 ms to energize the main contactor, check the following:
Fuses F-1 and F-2 on the power board C-6-1895-49 the fault will be seen as a step-start fault
and LED CR-56 on the front panel circuit board the HV regulator will be illuminated.
(D) Gun Ready (Using the optional Control Panel):
