This can happen if the NTS switch inputs are not wired or the incorrect number of switches
is specified in parameter 13-176.
Make sure that the NTS switches are wired in and going to correct terminals.
Verify that the number of switches in parameter 13-176 is set correctly for your specific job
(x01 = UT1/DT1, x02 = UT2/DT2, etc).
The fault records two extra bytes of information. The first
extra byte is the floor the car was trying to go to (0 = bottom
landing, 1 = 2
nd
landing, etc.) and the second extra byte is the
floor the car was at when this fault occurred.
The fault occurs when the car has been leveling for more than 15 seconds and has not seen
the destination door zone magnet.
After the fault is asserted, the controller will attempt to send the car on a correction run to
an available floor.
This fault can indicate a bad or missing door zone magnet or it can indicate a bad door zone
sensor. If this fault occurs often and the first extra byte is always the same, it probably
means there is a bad or missing door zone magnet at that floor. If the first extra byte
changes from one F232 to another, it probably means the door zone sensor is bad.
