Test procedure
1. The drive power section is switched off.
2. The auxiliary voltages are switched on.
3. The auxiliary voltages are checked.
Result
The test is passed if all of the auxiliary voltages are available.
3.2.4
Temperature monitoring in the control cabinet
Fundamentals
The control cabinet is equipped with temperature sensors to monitor the internal cabinet
temperature. The switching threshold of the temperature monitoring is checked. The selected
switching threshold is stated in the circuit diagram. The temperature is monitored on the test
station computer.
Test procedure
1. The auxiliary voltage is present.
2. The temperature sensor is heated up to the switching threshold T
1
.
A message is displayed on the test station computer.
Result
The test is passed if the drive responds as described when it reaches the switching threshold.
The tolerance range is ±5 K.
3.2.5
Redundant 230 V or 24 V auxiliary voltage supply
Fundamentals
The 230 V or 24 V auxiliary voltage supply of the control cabinet is redundant and has separate
fuse protection.
Test procedure
1. The drive power section is switched off.
2. The auxiliary voltage is present.
3. A miniature circuit breaker of the auxiliary power supply is opened.
The auxiliary power supply continues.
An alarm is displayed on the test station computer.
