B. Initial
Turn-on
1.0
The ‘Power ON’ LED on the front panel board should be illuminated. If the front
panel shows no lights, check the following:
1.
Check for power on the input power line (208VAC, 3-phase).
2.
Check the fuses on Regulator board 9120010 (see section 8.8 for fuse
details).
2.0
It is normal for the front panel ‘Fault’ LED to blink momentarily when the circuit
breaker is turned on. The ‘Fault’ LED should immediately go out, however if the
light does not extinguish, check if any fault LEDs are illuminated on the rear
panel. If one or more LED is illuminated, verify if the fault condition(s) is
present and correct if possible.
3.0
High Voltage Ready Status
The green ‘Ready’ indicator in the ‘HV ON’ pushbutton should be illuminated
when conditions are clear for HV on. If faults are present, this indicator will not
illuminate.
