Each table is organized around a set of operational symptoms that should be easily identifiable to
the operator. For functional descriptions of the HVPS front panel LEDs, see section 5.2. For
descriptions of the LEDs on the FPS, see section 3.3. The Ishikawa diagrams in section 5.3
provide additional information about the faults covered in many of the
troubleshooting tables.
Symptoms
TCS displays PSU1_RDY_ALM ( = Power Supply Control Not Ready Timeout Alarm).
•
HVPS Front Panel: No LEDs are lit, and displays are dark.
•
For additional information about this fault mode, see Ishikawa Diagram #1.
Possible Causes
1. Loss of main line power
2. Power supply's front breakers are
tripped.

Table 5-1 No Input Power Indicated

1. Check to see whether input line voltages a HVPS rear panel terminals L1, L2,
and L3 are within specifications for your facility. If so, proceed to next step. If
not, check circuit protection devices (i.e., either circuit breakers or fuses) on
the facility input power circuit to ensure they are not tripped or blown.
2. Reset front breakers and attempt to power up the unit. If breakers trip again,
proceed to next step.
