14. TROUBLESHOOTING GUIDE
15. ERROR HANDLING
- In case of a malfunction, check if the correct barrier was selected (paragraph 5)
- Dual ashing of the cover lights. Indicates that scheduled maintenance is required. Check the parameters -2ND level,
-2ND level, -2ND level.
- Leakage current to ground problem: the Inverter type 1 have a built-in high-attenuation noise lter and are grounded via a capacitor.
Switch a pulled to reduce the leakage current to ground. The reduced load get the inverter not compliance with the EMC
standard operate on switch with power o .
In memory up to 10 di erent errors, with its own occurrence limited to 10, are stored for each event.
In case of blocking error, the restart of the board is possible by keep pressed both the keys “+” and “-“ for 5 seconds or by switch o
and on the power supply. Restarting by keys, a memory check is performed with an automatic recovery of parameters out of range to
default factory values.
At level 4, by parameter “
”, the list of events and error stored in memory may be shown. It’s shown alternatively the error code xx
and the occurrence; use “+” e “-“ for scroll the list. At the end is shown the exit code: quitting (by pressing “F”) with
the error list is
preserved, quitting with
the history is clear.
Particular events not dangerous for properly execution are stored in memory, without block the automation.
Following the list of error and events with the indication of blocking or not property.
FAULT AND EVENTS TABLE:
Par Description LOCKING
Internal error on memory access. NO
Out of range memory address. YES
CRC on incorrect memory YES
Fuse F3 or F4 blow. YES
During the operation a STOP occurred, changing the normal automation.(*) NO
During the operation a FRAC occurred, changing the normal automation.(*) NO
Obstacle detected during operation. NO
Time-out elapsed in opening operation . NO
Time-out elapsed in closing operation. NO
Interruption on Ulink communication. NO
Programmed maintenance cycles reached. NO
Loss of communication with INVERTER NO
No. of ENCODER pulses out of range NO
Limit switch not working NO
Interruption on inverter communication, check the connection cable. NO
Inverter parameters password protected, must insert the password on the inverter. NO
Baud rate on incorrect communication YES
Modbus parity parameter error. Internal error. YES
(*) Events occurrence that change the normally automation (such as stopping, change of the direction operation, not operation star-
ting) are stored.
For example if a STOP signal turn on and o during a static status, the event is not saved; but if its presence prevents a command actua-
tion, or when stops a started operation, it is stored.
