Test procedure
1. The auxiliary voltage is present.
2. An operating time of 100 s is entered on the test station computer.
3. The drive is switched on.
Result
The test is passed if the fans switch over after the specified time.
3.2.24 Overtemperature, output reactor or sine-wave filter
Fundamentals
The temperature monitoring of the output reactor and/or the sine-wave filter is checked.
Test procedure
1. The drive is switched on.
2. The signal cable for "Alarm" is interrupted.
The drive remains switched on. The following message is displayed on the test station
computer.
"Reactor OT Alarm" (= overtemperature alarm)
3. The signal cable for "Fault" is interrupted.
The drive remains switched on. The following message is displayed on the test station
computer.
"Reactor OT Trip Alarm" (= fault announcement, overtemperature)
4. The inverter is switched off if the fault announcement is uninterrupted for 60 s.
The following message is displayed on the test station computer:
"Reactor OT Trip" (= overtemperature fault)
Result
The test is passed if the appropriate messages are displayed on the test station computer.
3.2.25 Bypass
Fundamentals
The appropriate bypass contactor must energize if a power semiconductor module fails. The
failure is simulated by withdrawing the fiber-optic cable connector from the gating module of a
power semiconductor module. This interrupts the control.
