Resetting parameters to factory defaults
It is possible to reset all parameters to the factory default settings. The fieldbus address is not affected from the reset command.
Also the different maintenance counters are not affected but must be resetted manually at the UMC100-PAN.
The reset command can be activated via:
• UMC100-PAN
Resetting the password
The password can always be set or disabled using the UMC100 DTM (PBDTM) or using the UMC100-PAN.
Reading, setting and resetting maintenance counters
Preventive maintenance is the best way to ensure the long service life of any equipment.
The UMC provides several counters which help to better plan maintenance activities or to track down an existing problem.
• Number of motor starts can help to identify worn-out power contacts or to determine on contactor wear
• Number of protection trips
• Motor operation hours can help to assess the bearing status and its lubrication
The maintenance counters are available at the UMC100-PAN and in the PBDTM.
