Description
Possible reason for error
F.38A
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
F.3A1
Number of trips for safety input
A has reached set limit
• Parameterized, maximum number of safety input trips during a door cycle was exceeded
F.3B1
Number of trips for safety input
B has reached set limit
• Parameterized, maximum number of safety input trips during a door cycle was exceeded
F.3C1
Number of trips for safety input
C has reached set limit
• Parameterized, maximum number of safety input trips during a door cycle was exceeded
F.3F4
2. external safety edge - testing
failed
• Pre-limit switch for safety edge incorrectly set or defective
F.400
Controller hardware reset
detected
• Strong interferences on the supply voltage
• Internal watchdog has triggered
• RAM error
F.401
Watchdog Error
• Internal Watchdog has released
F.409
RFUxK software incompatible
Only the expansion board RFUxK-F with the software version from V1. 11 can be operated in parallel with other
expansion boards on a CAN-bus.
F.40A
Software Exception
• Internal error detected
F.40B
Communication error expansion
board
• The communication between main board and expansion board is disturbed
F.40C
Unknown extension board
(CAN connection)
• Incorrect hardware coding of the extension board
• Control software does not support the expansion card
• Expansion card defective
F.410
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
F.420
Overvoltage in DC-bus Limit 1
• Brake chopper disturbed / defective / missing
• Mains voltage considerably too high
• Motor feeds back too much energy in generator mode. Not enough kinetic energy can be generated for the door.
F.425
Overvoltage line supply
• The supply voltage for the controller is to high
F.426
Undervoltage line supply
• The supply voltage for the controller is to low
F.430
Temperature heat sink outside
of working range Limit 1
• Too high load on the power amplifiers or the brake chopper
• Surrounding temperature too low for operation of the controller
• Clock frequency of the power amplifier too high (Parameter P.160)
F.435
Housing temperature high
• The temperature inside the controller housing is to high
