Service codes for push-pull calibration
Safety
Err | Eto
Cause: Incorrect measurement during push-pull calibration
Remedy: Repeat push-pull calibration
St1 | E 1
Cause: At minimum wire feed speed, the wire-feed unit motor does not deliver any
actual rotational speed value.
Remedy: Repeat the push-pull calibration. If the error message re-appears: check
the actual-value pick-up and the cable connections to and from it
St1 | E 2
Cause: At maximum wirefeed speed, the wire-feed unit motor does not deliver any
actual rotational speed value.
Remedy: Repeat the push-pull calibration. If the error message re-appears: check
the actual-value pick-up and the cable connections to and from it
St1 | E 3
Cause: At minimum wire feed speed, the wire-feed unit motor does not deliver any
actual rotational speed value.
Remedy: Repeat the push-pull calibration. If the error message re-appears: check
the actual-value pick-up and the cable connections to and from it
St1 | E 4
Cause: At minimum wirefeed speed, the motor of the push-pull unit does not
deliver any actual rotational speed value.
Remedy: Repeat the push-pull calibration. If the error message re-appears: check
the actual-value pick-up and the cable connections to and from it
WARNING! An electric shock can be fatal. Before opening up the machine
- Move the mains switch to the “O” position
- Unplug machine from the mains
- Ensure that electrically charged components (e.g. capacitors) have been
discharged

Checking actual-
value pick-up
The actual-value pick-up is checked by measuring the direct voltage on the actual-value
pick-up leads.
Motor not activated:
- the voltage on the actual-value pick-up cable connections is approx. 13 V.
Motor activated:
- The motor speed is conveyed in the form of impulses on the actual-value pick-up
cable connections.
- The voltage sinks to approx. 11 V.
