Hardware faults

"Fault no.: 300"
Possible cause:
Voltage above maximum value.
Remedy:
1. Check battery voltage (12 V or 24 V).
DANGER – Risk of electric shock from live
parts. Observe the electrical engineering safety
regulations.
2. If the voltage of a 12 V battery is correct, check the
voltage at power module 1 and power module 2 at
measuring points U
actual
 The voltage must be 0.85 V +/- 0.007 V.
3. If the voltage of a 24 V battery is correct, check the
voltage at power module 1 and power module 2 at
measuring points U
actual
 The voltage must be 1.7 V +/- 0.007 V.
4. Replace power module 1 or power module 2 if U
is too high.
"Fault no.: 310"
Possible cause:
Voltage below minimum value.
Remedy:
1. Check battery voltage (12 V or 24 V).
DANGER – Risk of electric shock from live
parts. Observe the electrical engineering safety
regulations.

 The voltage must be 1.7 V +/- 0.007 V.
4. Replace power module 1 or power module 2 if U
is too low.
"Fault no.: 320"
Possible cause:
Voltage at output is unstable.
Remedy:
1. Check battery voltage (12 V or 24 V).
DANGER – Risk of electric shock from live
parts. Observe the electrical engineering safety
regulations.

 The voltage must be 1.7 V +/- 0.007 V.
4. Replace power module 1 or power module 2 if U
is unstable.
"Fault no.: 330"
Possible cause:
Current above allowed maximum value.
Remedy:
DANGER – Risk of electric shock from live
parts. Observe the electrical engineering safety
regulations.
¶
Open BAT 690 and ensure that all connecting cables
are in perfect condition, and are connected up
correctly (see sec. 6).
¶
Check battery.
¶
Check charging cables.
If the fault persists - check power module 1:
1. Remove connecting cable between power module 1
and power module 2 (Fig. 17, item 13).
2. Remove battery connection cables from power
module 2. (Fig. 17, item 5)
3. Only connect battery connection cables with power
module 1 (Fig. 17, item 4).
4. Connect circuit board M1 to power module 1.
5. Switch on BAT 690 and set up back-up mode.
6. Connect charging cables to the battery.
7. Start back-up mode.
 The current value appears on the display.
 If the current value matches the set value (max.
30 amps), power module 1 functions.
 If the current value exceeds the set value (max.
30 amps), power module 1 is defective.
8. Replace power module 1 if the current value
exceeds the set value.
If the fault persists - check power module 2:
1. Remove battery connection cables from power
module 1. (Fig. 17, item 4)
2. Only connect battery connection cables with power
module 2 (Fig. 17, item 5).
3. Connect circuit board M1 to power module 2.
4. Switch on BAT 690 and set up back-up mode.
5. Set the parameter voltage to the maximum value.
6. Connect charging cables to the battery.
7. Start back-up mode.
 The current value appears on the display.
 If the current value matches the set value (max.
30 amps), power module 2 functions.
 If the current value exceeds the set value (max.
30 amps), power module 2 is defective.
8. Replace power module 2 if the current value
exceeds the set value.
