The elevator control received signals from the hoistway
information system which aren't signals of the expected
hoistway information system type.
C1:Wiring to hoistway end position sensor is faulty.
A1:Check KSE
Measure:
--Check if the magnets are still correctly installed
» Distance between magnet switch and magnet must be 8 to
12 mm
--Check magnet polarity, uppermost KSE-U (uppermost
stop) north polarity, bottom south polarity
--Check connections on magnet switch
--Check KSE connections on the SDIC printed circuit board
--Measure on KSE plug
» Measure pin 2 KSE D against ground
» Measure pin 4 KSE U against ground
Car at the lowermost floor:
» KSE D=0 and KSE U =1
Car at the uppermost stop:
» KSE D=1 and KSE U =0
Car at every other stop:
» KSE D=1 and KSE U =1

C2:Wiring to hoistway end position sensor is faulty.
A2:Check wiring and correct connection of the
corresponding sensor (KSE, KSE_U, KSE_D).
