Service
Warning signal
Expiry of the time remaining until service is signaled.
Warning service
DC-link
For linking to frequency inverter functions.
50 -
For output via a digital output. Select the signal source for one of the
parameters 531, 532, 533, or 554.
See chapter 7.6.5 "Digital outputs".
Operation Mode Service Interval DC-link 1534 must be set to "2 - Warning".
Time remaining until next service
1530 Service Interval DC-link
Parameter
Service Interval DC-link 1530 indicates the service interval remaining until next service in
percent. If a value of 0% is displayed, service is recommended. It should also be checked if the com-
ponent must be replaced.
High ambient temperature and frequency inverter is not in operation:
Even with the frequency inverter switched off, the electrolyte capacitors may age due
to high ambient temperatures. The times at which the frequency inverter is switched
off are not considered in the calculation of the time remaining until next service. As
service interval until next service may be too long.
The remaining service interval until service is an estimated value.
The remaining service interval until service (parameter Service Interval DC-link 1530) can be set to
100% if setting "1 - DC-link" is selected for parameter
Reset Service Intervals 1539.
10.3.2 Fan
Signalling when service is required
The service interval remaining until service of the fan largely depends on the wear and tear of the
bearing components. For this reason, the service interval remaining until service depends on the
speed and operating time of the fan. The service interval remaining until service is calculated from
these two values.
1535 Operation Mode Service Interval Fan
Via parameter
Operation Mode Service Interval Fan 1535, you can set how the warning is to occur
when the remaining service interval until service has expired. The information can be indicated in a
parameter or a service message can be output.
