Monitoring the supply voltage (eliminated from DPLC V8.3 onwards)
Eliminated from:
EPL-10200 (Drive PLC) from V8.3 onwards
Behaviour of the new version
If the monitoring function for the 24 V supply voltage detects that the voltage is between 15 V and 17.5 V while the Drive PLC is running, the system error message U15 (C0168/1=1070) is triggered and 'message' is indicated. The system error message is not triggered when the Drive PLC is switched on or off.
What happens?
Although the monitoring function for the 24 V supply voltage included in the Drive PLC detects that the voltage is below 15 V the system error message U15 (C0168/1=70: undervoltage of internal 15 V supply voltage) is not triggered.
When does the problem occur?
The response described before occurs sporadically.
Which products are affected?
EPL-10200 (Drive PLC) V8.2 and lower
Possible diagnostics?
None.
Short-term measures/recommendations?
None.
Evaluation:
The function restriction has been eliminated from firmware version V8.3 onwards.
