E
HW-ERROR
No
Hardware component failure. Multiple reasons can
cause this error. For example:
•
An internal supply voltage has failed
•
Internal communication to power-module has
timed out
•
The controller has detected a power-module
error-condition
•
The internal current measurement has failed
Determination of the precise reason can only be
done by experts, possibly also using the errors log.
F
BALLAST
Yes
This error can be caused by two reasons:
•
Ballast resistor overload. The ballast resistor
load has exceeded the configured value (Ballast-
P). This error can be reset after a timeout has
elapsed.
•
Hardware failure in the ballast circuit or resistor
12.1.1 Charger (option) errors
If the built-in charger option is mounted in the IMD, the following errors can be read from the charger
warnings register:
Error
bit no.

Error description
0
OPENCIRCUIT
The charger detected open circuit. No safe energy source is
connected, or a wire is broken.
1
SHORTCIRCUIT
The SE output is short-circuited.
For lead acid this error is raised when the SE voltage is less than
20% of nominal while charging.
2
CHARGERTEMP
The internal temperature of the charger is too high.
