PS A FAULT 3
PHASE 350 V DC BUS OVERVOLT ERROR
This error is reported when a given Phase DC internal bus experiences an 350V
threshold voltage condition. This error is a run-time recoverable error. From the front
panel press the ENTER key. Through SCPI, send the *RST command.
PS A FAULT 4
PHASE 380 V DC BUS OVERVOLT ERROR
This error is reported when a given Phase DC internal bus experiences a 380V
threshold over voltage condition. This error is not a run-time recoverable error. The TW
power should be cycled. If this error appears excessively, consult the Elgar technical
support staff.
SELF TEST FAULT
This error will occur if:
1.
The amplifier installed quantity is incorrect in the Menu system. Perform section
3.10.20. CONFIG/INSTALLED should be set to:
•
1 if the TW has one amplifier installed (1750)
•
2 if the TW has two amplifiers installed (3500)
•
3 if the TW has 3 amplifiers installed (5250)
2. On rare occasions th TW will fail power on self test due to erroneous data
transmitted to the microprocessor. To correct this condition simply turn off power,
wait 30 seconds and re-power the TW.
3. The TW has failed and will require service if this fault cannot be cleared by cycling
the power
