Error message
Description
Lift controller reaction
communication faults
follows.
If the data transfer is again without
errors, then there is a return to
normal operation.
At a CAN failure of a TSE or ESE-
assembly, the lift remains in
operation; there will be no
emergency stop.
129/65 CANB bus off
Automatic shutdown of the
CAN bus B (shaft bus) due to
many communication faults
Lift keeps in operation; internal test
of data transfer.
129/81 ESE err.branch x
CAN bus errors on shaft bus,
branch x.
Check CAN bus (wiring,
termination resistor, ...).
Possible reason may be switch
off/on of a single lift inside a group.
129/82 Branch off
Automatic shutdown of the
CAN bus (branch x of the shaft
bus) due to many
communication faults.
See above
129/83 Error local ESE
CAN bus errors on shaft bus to
an ESE, plugged directly on the
HSE.
See above
129/96 No control bus
Data transmission on the CAN
bus (control bus) is not
possible.
Possible reasons:
- No CAN bus cable connected
- No other bus module
connected
- PCB defective
Emergency stop , thereafter
internal test of the data
transmission.
If the data transfer funktions again,
then the system returns to normal
operation.
129/97 CAN TX Overr.
CAN transmit buffer overflow
on control bus
Possible reasons:
- Bus load too high
- Frequently switching inputs
- Errors in the controller
software
Emergency stop.
Check signal connection to
controller inputs.
Contact lift controller manufacturer.
129/98 No shaft bus
Data transmission on the CAN
bus B (shaft bus) is not
possible.
Possible reasons:
- No CAN bus cable connected
- No other bus module
connected
- PCB defective
Lift continues operation.
Internal test of data transmission
129/99
CANB TX Overr.
CAN transmit buffer overflow
on shaft bus
Possible reasons:
- Bus load too high
Lift continues operation.
Check signal connection to
controller inputs.
Contact lift controller manufacturer.
