Warning description
D
Warning D
Not used
E
HW-warning
This warning can be caused by the following reasons:
•
Current offset too high (too far from zero)
•
Pt100 measurements are wrong, measured value cannot be
trusted
•
DI 10, 11 or 12 is high when not in manual operation mode (and
manual mode is enabled).
F
BALLAST
The ballast resistor load is over 50% the configured maximum
value.
12.2.1 Charger (option) warnings
If the built-in charger option is mounted in the IMD, the following warnings can be read from the
charger warnings register:
Warning
bit no.
Warning text
Description
0
BATTEMP
The battery temperature is more than 10ºC outside charging
temperature limits (-20ºC to 50ºC). Lead acid only.
1
TEMPCHANNEL
The defined temperature sensor channel is not valid.
2
VinLOW
The input voltage from the DC-link is below 270 V DC.
3
Vin-VseLOW
The input voltage from the DC-link is not at least 15 V DC higher
than the SE voltage.
4
LOWCURR.
The output current is too low compared to setpoint.
12.3
Errors log
The IMD has an error log containing up to 20 entries. The log is a rolling log using “First In First Out”
principle, which means that it always contain the latest 20 errors generated by the IMD, with the latest
error at the top. The log entries are available in the IMD Manager and through CAN/CANopen. Each
entry contains the following parameter values at the time the error occurred (see description of the
register in the Integration manual for details):
