Input Over-voltage (after three incidents)
Possible Cause
Action
Source AC too high for power controller
Check AC voltage at isolation transformer
primary; ensure that transformer primary is wired
to match voltage available at site.
Check voltage at transformer secondary with
multi-meter, confirm that it is less than 660 VAC
+10%.
Improper transformer design or construction
See transformer design requirements in
Appendix A.
Input Under-voltage or Damaged Unit
Possible Cause
Action
Low or no AC voltage at input to DC power
controller
Check AC voltage at isolation transformer
secondary with multi-meter, confirm that it is
greater than 220 VAC -10%.
Low or no AC voltage at input to isolation
transformer
Check AC voltage at transformer primary with
multi-meter, confirm that it meets transformer
specification.
Over-temperature
Possible Cause
Action
Fans on G2 controller board not functioning with
correct AC voltage at G2 board input
Visually inspect to see if both fans operational
–
if not board requires repair.
Inadequate cooling of enclosure
Check temperature inside enclosure during
operation, ensure is less than 50°C.
Fan-cooling insufficient
Check fan sizing, ambient temperature; possible
need for air conditioning or vortex cooling.
