4.8.4.2 Error messages during operation
Error messages during operation are signaled with the Error and RUN LEDs.
The RUN and TOR relays are switched off when this happens (OFF).
The following error messages may be issued during operation (RUN, TOR):
Table 22: Error messages during operation
Phase faults can only be detected while the start ramp (t-Start) is active.
Once the start ramp is no longer active (TOR), it will no longer be possible to
detect a phase failure.
Message (PNU)
Errors
Possible causes
Remedy
Heat sink
overtemperature/
undertemperature
(860.16)
Heat sink temperature
≦
0 °C or
≧
+80 °C
Device still overheated from
last start/stop
Wait for cool-down time to elapse; use fan
(DS7-FAN-032) if necessary
Excessively high control
cabinet temperature; fan filter
soiled
Monitor the temperature in the control panel
Undertemperature; ambient
air temperature is too cold
Heat up the room or control panel and monitor the
temperature
Specifications for
connection to supply
voltage faulty
(860.19)
Excessively low voltage for
regulator supply (U
s
< 20 V DC)
Overload of the external
power supply unit
Check dimensioning and overload of the power supply
unit
Supply voltage not available
Check control signals for switching the supply voltage;
install interlocks for start command if necessary
→
The mains frequency is not monitored during operation.
This makes it possible to ensure reliable operating behavior
even under adverse conditions, such as those that are prevalent
when there is an unstable generator (mains supply voltage).
Proper operation can only be ensured within the permissible
limits of 50/60 Hz ± 5 %.
