2 GENERATOR CONDITION AFTER FAILURE EVENT
ENF1 and/or ENF2 and/or ENF3 tripped.
Mains fuses might have additionally tripped.
2.1 SPECIAL CASE
ENF3 tripped, possibly in combination with ENF2 and ENF1 and mains fuses:
Problem most likely caused by rotor control unit EY (high speed) or EYA (low speed).
Solutions for rotor control problems are not part of this document.
2.2 ALL OTHER CASES
The generator has to be kept in this condition to discover the cause of the problem.
A non-qualified person (e.g. hospital technician not familiar with Optimus) should not be asked to just turn the
fuses back on to prevent further damage.
A qualified person like a Philips field engineer (trained on Optimus) must visit the site.
2.3 PREREQUISITES BEFORE CHECKING THE GENERATOR
CAUTION
Do not remove PCB kV-power from the IGBT transistors.
Electrostatic discharge and mobile phone waves can damage and destroy IGBTs
when gate connections are open.
WARNING
The generator must be switched OFF and must be completely cut from mains (e.g.
room mains switch or earth leakage current breaker).
All following checks must be made without mains power
