Possible reason for error
Safety input incorrectly parametrized
• A safety edge is connected but deactivated
• With FUZ2: Safety input Jumper incorrectly set (as digital input jumpered but
as safety edge set)
Redundancy error of the 8K2 slip door switch on the
second internal safety edge evaluation unit
• One of the contacts of the redundant 8k2 slip door switch is defective
• The slip door was not fully opened or closed
Number of trips for safety input A has reached set
limit
• Parameterized, maximum number of safety input trips during a door cycle
was exceeded
Number of trips for safety input B has reached set
limit
• Parameterized, maximum number of safety input trips during a door cycle
was exceeded
Number of trips for safety input C has reached set
limit
• Parameterized, maximum number of safety input trips during a door cycle
was exceeded
2nd external safety edge - testing failed
• Pre-limit switch for safety edge incorrectly set or defective
• Processing module defective
• Safety edge defective
Controller hardware reset detected
• Strong interferences on the supply voltage
• Internal watchdog has triggered
• RAM error
• Internal Watchdog has released
RFUxK software incompatible
Only the expansion board RFUxK-F with the software version from V1. 11 can
be operated in parallel with other xpansion boards on a CAN-bus.
- The software version of the expansion board RFUxK-A/E is less than V1. 11
- the expansion boards are connected to different CAN interfaces (e.g. RFUxK-
A/E to CAN1 or CAN2 and RFUxK-F to CAN2 or CAN1)
unplanned software reset of the processor
Communication error expansion board
• The communication between main board and expansion board is disturbed
Unknown extension board (CAN connection)
• Incorrect hardware coding of the extension board
• Control software does not support the expansion card
• Expansion card defective
Over-current (motor current or DC-bus)
• Wrong motor data set (P.100 – P.103)
• Non-adjusted voltage increase / boost set (P.140 or P.145)
• Motor not properly dimensioned for door
• Door sticks
The brake chopper under heavy load
The brake chopper has to withstand heavy loads. The trip is interrupted to give
the chopper an opportunity to cool down. The fault resets itself after cooling.
