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. 

Interlocking: - 
Fault causes: 

1)  External unit indicates faults (for alarm text options 1-4). 

 

2)  The rectifier has been shut down by remote control (for alarm text option 

5). 

 3) 

Unused 

input 

Ext. fault

 is not strapped. 

Other: The 

Functions

 menu, section 

 

5.13.10, can be used to select one of the above 

alarm texts to be displayed for an alarm. Function option no. 1 applies to the 
first four text options. 
Function option no. 2 applies to the 

External blocking

 text option. This means 

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 e49°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.
