4. Check voltage at measuring points M1 and M2 on
the power module (see sec. 5.6).
 Voltage must be 230 V.
 If the voltage differs or is not present, the device
fuse is defective.
5. Replace power module if the voltage differs or is not
present.

Faults during charging

"Fault no.: 200"
Possible cause:
Maximum ampere-hour value exceeded
(> 120% rated capacity)
Remedy:
1. Check charging parameters and correct if necessary.
2. Check battery.
3. Charge only lead-acid batteries and lithium iron
phosphate batteries with a rated voltage of 12 V or
24 V.
"Fault no.: 210"
Possible cause:
Maximum charging time in charging phase 0 exceeded.
Remedy:
1. Check charging parameters and correct if necessary.
2. Check battery.
3. Charge only lead-acid batteries and lithium iron
phosphate batteries with a rated voltage of 12 V or
24 V.
"Fault no.: 220"
Possible cause:
Maximum charging time in charging phase 1 (constant
current) exceeded.
Remedy:
1. Check charging parameters and correct if necessary.
2. Check battery.
3. Charge only lead-acid batteries and lithium iron
phosphate batteries with a rated voltage of 12 V or
24 V.

Hardware faults

"Fault no.: 300"
Possible cause:
Voltage above maximum value.
Remedy:
1. Check battery voltage. (12 V or 24 V).
2. Replace battery if battery voltage differs.
DANGER - Risk of electric shock from live
parts. Observe the electrical engineering safety
regulations.
3. Check the voltage at the measuring points U
and GNDA on the power module using the correct
battery voltage from a battery with 12 V (see sec.
5.6).
 The voltage must be 0.85 V +/- 0.007 V.
4. Check the voltage at the measuring points U
and GNDA on the power module using the correct
battery voltage from a battery with 24 V (see sec.
5.6).
 The voltage must be 1.7 V +/- 0.007 V.
5. Replace power module if U
