2-1 Troubleshooting Entry
Note1: If cable 2109186 emergency safety loop is not
connected to XJ10 on 200PL2 but instead cable from
autotransformer is connected, autotransformer thermo
switch 120°C can switch off the system in case of overload.
See block diagram Generator power up sequence no. 1,
then wait between 1 hour and 2 hours for the recovery
console button "OFF" to be lit.
Note2: If cable 2109186 emergency safety loop is not
connected to XJ10 on 200PL2 but instead cable from
autotransformer is connected, 200PL1 main distribution
board TR2 thermo switch 120°C can switch off the system
in case of overload. See block diagram Generator power up
sequence no. 1, then wait 30 minutes for the recovery
console button "OFF" to be lit.
Failure: If the 200PL1 X1 relay does not engage,
200PL2 DE2 and 200PL1 DE5 both blink.
Failure: If K1 does not engage.
Check the X-ray Console ON button is functioning cor-
rectly.
If the problem persists, check TP5 on 200PL2 is at
12 V when the X-ray Console ON button is pressed.
If TP5 is at 12 V, check the thermal switch status on
XJ10 200PL2.
If TP5 is not at 12 V check, the LED status of DE4,
DE5, DE6, and DE7 on 200PL1. If the problem per-
sists, see
Power-Up Sequence on page 1071
Failure: If K1 does not stay engaged see Power-Up
Sequence on page 1071 .
Failure state present if "Power_Supply_Present" is not
detected. In this case, the:
• Console display is blank and beeps at 1 second
intervals, and the button on console is lit
• 200PL1 DE6 and 200PL2 DE1 are lit
See
Main Power Contact K1 Engaged but Console
Beeps at 1 s Intervals on page 1079 to resolve.
Probable cause is that 400PL2 board TP27 is stuck at
"0", or that the 400PL3 board +5 V is out of tolarence.
Failure state present if "INV_SUPPLY_OK" is not
detected. In this case, the:
• button on console is lit
• Error message "E08 Generator: time out on signal
INV_SUPPLY_OK (going "low" or "high") 071/082"
on console display
See E08: 071/082 Error on the Console Display on
page 1081 to resolve.
