FC MECHANICAL BRAKE KBKB1 PERSISTENT FATAL
Too many brake failures (KB and KB1) have occurred within a certain limit of
trips (typically > 3 failures/100 trips). The elevator is blocked.
C1:Brake power is missing
A1:Check general wiring of brake power circuit
C2:The brake position feedback signals KB and KB1 are faulty
A2:Check on the service interface menu (for example, 724 or 30624) the
states of the brake position feedback signals.Check brake contacts KB
and KB1 for dirt.Check general wiring KB and KB1.
C3:Brake opens only partially
A3:Check brake supply voltage
C4:The brake is mechanically bad adjusted
A4:Replace brake

FC MECHANICAL BRAKE KB PERSISTENT FATAL
Too many brake failures (KB) have occurred within a certain limit of trips
(typically > 3 failures/100 trips). The elevator is blocked.
C1..C4: See error 1572 (applied for KB)
A1..A4: See error 1572 (applied for KB)

FC MECHANICAL BRAKE KB1 PERSISTENT FATAL
Too many brake failures (KB1) have occurred within a certain limit of trips
(typically > 3 failures/100 trips). The elevator is blocked.
C1..C4: See error 1572 (applied for KB1)
A1..A4: See error 1572 (applied for KB1)

FC WRONG PHNRx SEQUENCE
The drive frequency converter received a inconsistent relevel zone signal
sequence from the shaft information system (for example, two times rising
edge from PHNR_U or PHNR_D).
C1:Bad alignment of the PHNR_U/PHNR_D sensors
A1:Check positions of the PHNR_U/PHNR_D sensors
C2:Dirt on vanes
A2:Clean the vanes in the hoistway
C3:Bad signals through external light source
A3:Check proper shielding from sunlight (glass shaft)
C4:Communication problem, EMC
A4:Check communication on CAN bus (SDIC7x, SCIC)

FC RELEVELING DISTANCE EXCEEDED
The drive frequency converter (FC) wasn't able to level the car on the floor
because the maximum relevel distance was exceeded.
C1:Parameter 'max releveling distance' is set wrong
A1:Check parameter 'max releveling distance' at drive frequency
converter. The value should be 1.3 to 1.5 times bigger than the maximum
allowed rope elongation at the specific installation.
C2:Bad alignment/position of the PHNR_U/PHNR_D sensors
A2:Check positions of the PHNR_U/PHNR_D sensors. Check that the
displacement of the releveling sensors (PHNR_U/PHNR_D) is according
to the schematics. They should be inactive when the car is about 15 mm
below or above floor level.
