Cause
The supply unit was not ready
(ie. the main contactor/breaker
could not be closed) within
expected time.
Selected signal has fallen
below the user underload
curve.
Selected signal has exceeded
the user overload curve.
An analog signal is outside the
limits specified for the analog
input.
Fault generated by the signal
supervision 1 function.
Fault generated by the signal
supervision 2 function.
Fault generated by the signal
supervision 3 function.
Fault in external device 1.

Fault in external device 2.

What to do
Check that communication to the supply
unit has been activated by
options word
1.
Check setting of parameter
max charging
time.
Check that the supply unit is enabled,
allowed to start, and can be controlled by
the inverter unit (eg. not in local control
mode).
See
A8BF ULC underload warning
509).
See
A8BE ULC overload warning
508).
Check the auxiliary code (format XXXX
XYZZ). "Y" specifies the location of the
input (0: Control unit, 1: I/O extension
module 1, 2: I/O extension module 2, 3:
I/O extension module 3). "ZZ" specifies
the limit (01: AI1 under minimum, 02: AI1
above maximum, 03: AI2 under
minimum, 04: AI2 above maximum).
Check signal level at the analog input.
Check the wiring connected to the input.
Check the minimum and maximum limits
of the input in parameter group
Standard
AI.
Check the source of the fault (parameter
32.07 Supervision 1
signal).
Check the source of the fault (parameter
32.17 Supervision 2
signal).
Check the source of the fault (parameter
32.27 Supervision 3
signal).
Check the external device.
Check setting of parameter
External event 1
source.
Check the external device.
Check setting of parameter
External event 2
source.
