DISTR.FUSE FAULT
Function: Monitors distribution fuses.
Alarm condition: Digital input for Fuse fault, is open.
Fault causes: 1) Tripped fuse.
2) Unused input Fuse fault is not strapped.
Interlocking: -
EQ.CHARGING BLOCKED
Function: Warns for illegal request for equalizing charging.
Alarm condition: Equalizing charging requested or in progress at the same time as digital input
for blocking of equalizing charging, EQ. Blocked, is open.
Interlocking: Digital input for blocking of equalizing charging E.F. Blocked, is closed. (i.e.
equalizing charging is permitted).
Fault causes: 1) Flow sensor for battery compartment fan indicates a fan fault.
2) Load that is protected against a raised voltage level is connected.
3) Unused input EQ. Blocked is not strapped.
Other: The alarm is usually activated following selected alarm delay. This gives any
flow sensor time to react, however, the raising of voltage is immediately
blocked without delay as long as the digital input for blocking of equalizing
charging is open.
EXTERNAL FAULT
INVERTER FAULT
DC/DC FAULT
ALARM PANEL ALARM
EXTERNAL BLOCKING
Function: 1) Monitors faults in an external unit.
2) Remote control (on/off) of rectifier units.
Alarm condition: Digital input for external faults, Ext. fault, is open.

that the rectifier units are controlled on/off via the digital input. The rectifier
units are switched on by closing the input and are switched off by opening the
input.
INTERNAL FAULT
Function: Monitors internal functions in the monitoring unit.
Alarm condition: See relevant fault type below.
Interlocking: -
Other: Alarm text followed by a fault code. Each fault type has its own alarm
condition. Most internal faults require correcting by qualified service
personnel.
FAULT TYPE 01
Alarm condition: The battery temperature drops below -19°C or exceeds +49°C.
Fault causes: 1) The temperature is really so low/high. Fix the cause of the low/high
temperature.
2) External temperature sensor missing but temperature measurement is still
selected in the Functions menu, see section 5.13.4. Install temperature sensor
or deselect temperature measurement.
