FC HEARTBEAT
The drive node has recognized a lost of communication to the elevator main
control. Note that this error mainly occurs together with other errors. Please
check message log first for other reported errors.
C1:Drive node disconnected (for example, CAN bus)
A1:Reconnect node
C2:Data transmission faulty (for example, CAN bus)
A2:Check general data line connection.Check for correct data line
termination (jumpers and switches, if present) of all devices (PCBs)
connected to the data bus.Check shielding of data line (if present).Check
for EMC disturbances.
C3:No or bad power supply of elevator main control
A3:Check power supply
C4:Elevator main control defective
A4:Replace corresponding hardware

FC OUTPUT CONTACTORS SUPERVISOR PERSISTENT
One or more drive main contactor does not operate as expected.
C1:The contactor feedback signal is faulty
A1:Check on the service interface menu (for example, 723 or 30623) for
the state of the contactor feedback signal.Check general wiring of
contactor feedback signal (for example, to DIN1 and DIN2 of drive)
Perform a manual reset respectively perform the persistent fatal error
reset procedure to set the elevator back in operation.
C2:A contactor is defective (for example, contacts stuck together)
A2:Replace defective contactor (for example, SFx, SHx, SB). Perform a
manual reset respectively perform the persistent fatal error reset
procedure to set the elevator back in operation.
C3:The contactor control electronics is defective
A3:Replace defective electronics (PCB, for example, MCCE). Perform a
manual reset respectively perform the persistent fatal error reset
procedure to set the elevator back in operation.
C4:Some drive types do not have a dedicated logical input (HW)
reflecting the state of the safety circuit which is used to determine a
failure at one of the drive main contactors. These drives are informed by
a data telegram (for example, CAN) from the elevator main control about
the state of the safety circuit. The safety circuit has opened but the
mentioned telegram was not transferred.
A4:Check general data line connection.Check for correct data line
termination (if present) of all devices connected to the data bus.Check
shielding of data line (if present).Perform a manual reset respectively
perform the persistent fatal error reset procedure to set the elevator back
in operation.
