DRIVE_TIMEOUTERROR
Description:
Time out in communication with power electronics.
Possible cause:
• Power electronics is not switched on by the PCB
• EMV-Disorder
• Hardwarefailure, faulty wiring
Rectification:
1. Check the wirings power electronics to PCB
2. Replace the PCB (Pos. 198)
3. Replace the power electronics (Pos 212)
Interruption
Current process is
interrupted. Tool is in
standby mode again.
E33
DRIVE_OVER
TEMPERATURE
Description:
Over-temperatur of power electronic.
Possible cause:
• End-phase-temperatur above 105°C
• End-phase-temperatur sensor defective
Rectification:
1. Let tool cool down
2. Replace the power electronics (Pos 212)
Interruption
Current process is
interrupted. Tool is in
standby mode again.
E34
DRIVE_UNDERVOLTAGE
Description:
Under-voltage at drive end-phase
This error code is bypassed to E23
Possible cause:
• Temporary voltage drop (<8.5V) caused by high
current consumption
• Empty battery during operation
Rectification:
1. See failure code E23
Interruption
Current process is
interrupted. Tool is in
standby mode again.
E35
DRIVE_OVERVOLTAGE
Description:
Over-voltage at drive end-phase
Possible cause:
• Batterie-voltage to high >24.5V
• Voltage peaks
• Voltage measurement on end-phase defective
Rectification:
1. Replace Battery
2.
Replace the power electronics (Pos 212)
Interruption
Current process is
interrupted. Tool is in
standby mode again.
E36
DRIVE_COMTIMEOUT
Description:
Communication time-out with Controller (PCB).
Possible cause:
• Wiring faulty
• Hardware defective
Rectification:
1. Check the wirings power electronics to PCB
2. Replace the PCB (Pos. 198)
Interruption
Current process is
interrupted. Tool is in
standby mode again.
E37
DRIVE_CURRENTLIMIT
Description:
Short circuit (Overcurrent) during welding
Possible cause:
• Tool is blocked during welding
• Current measurement on on the power electronic is
faulty.
Rectification:
1. Clean the tool, remove blockade
2. Replace the power electronics (Pos 212)
Interruption
Current process is
interrupted. Tool is in
standby mode again.
