Common pin. By closing the contact between pin 1 and any of the other pins ( 2, 3, 4, 5) to
start the function you need. This pin is connected to 0VDC and to the ground.
Remote start. Clockwise. Torque control.
Reverse remote start. Counterclockwise. Torque control.
Stop motor. “STOP MOTOR ON” screen. Motor stops and starts again after the contact has
opened.
Torque reached signal. Signal is 24VDC.
Lever signal: when lever is pressed or when the start is remote. No signal during unscrewing
cycle. It resets after their release. Signal is 24VDC.
Error signal: it activates every time an error occurs.
Error signal resets when the torque is reached or after releasing the lever or of the remote start.
Signal is 24VDC.
Common pin for any output. Signals must be taken between this pin ( 0VDC common) and the

The brushless motor and control unit are maintenance free, which means they are not subjected to
wear and tear. Kolver suggests greasing the gears after half a million cycles.
Should you have any problems or doubts, please contact the nearest Kolver technical centre.
We kindly remind you to switch the control unit off when not in use.
NOTE
The sound level generated by Kolver electric screwdrivers is always lower than 70dB(A).
The vibrations transmitted to operator’s hand are lower than 2.5m/s². In particular the exposition to
vibrations is lower than 1m/s² for operators who make up to 4200 screwing cycles per day.
IMPORTANT: For each second of operation the motor needs 3 seconds of rest, as indicated on the
tool label (1s/3s). Failure to do so may result in motor overheating and eventually damage and will
be considered as a misuse. Our warranty will not apply.
