Power Supply Over-
loads at Each Attempt
to Turn kV ON
1. Activate HV ON. Check for
approximately 120VAC
from terminal TB2 #5 to
TB2 chassis ground.
2. In the HV ON condition,
check for 120VAC from
wire #10 to TB2 chassis
ground.
3. In the HV ON condition,
check for 120VAC from
Master Control board J3-
25 or 27 to TB2 chassis
ground.
4. In the HV ON condition,
check for 120VAC from
TB2 #12 to TB2 chassis
ground.
1. Check for approximately
120VAC from TB7(L) to
TB7(N).
2. Check for approximately
120VAC from TB7-F1 to
TB7 - F2.
1. Disconnect the HV cables
from the power supply and
attempt HV ON.
2. Verify that the overload
setting is correct.
3. Reduce the KV setting and
turn HV ON.
1. Check wires and wire connections from the
power supply terminals to the external HV
ON control device. If wiring is OK, check
the output of the control device being used.
2. One of the normally closed contacts that
make up the HV OFF circuit is open. Check
any external equipment connected to wires
#3,35,8A,9 or 10. Also check any pneumatic
signals connected to PS2 and PS3. PS2
should have a 0 psi input and PS3 should
have greater than 30 psi pressure.
3. Replace the Master Control PC Board.
4. Replace the Motor Control Board.
1. Check factory voltage from the external
fused disconnect or constant voltage trans-
former (CVT) if used.
2. Replace Fuse F1 and/or F2.
1. If no overload occurs, inspect and perform
maintenance on the remainder of the sys-
tem.
2. Refer to the "Overload Adjustment Proce-
dures" section of this manual.
3. If no overload occurs, replace the Master
Control Board and repeat HV ON. If the prob-
lem still exists, then there is likely a problem
with the power supply tank. Consult your
Ransburg representative or the Ransburg
Service Department for instructions.
