Possible cause
No speed programmed for
counterclockwise rotation.
Operator releases start trigger
before the controller stops the
tool.
The fastening time exceeds
the standard time of 10 sec-
onds.
Tool exceeds the angle set-
point.
Speed is the same in all
stages.
Disabled by parameter setting. ► Parameterize the work light: In the CLPC100
Battery voltage is too low.
Battery is not fully charged.
High torque is needed during a
fastening sequence, e.g. for
coated fastenings.
Battery is at end of life.
Encoder is defective.
Tool temperature is too high.
Battery voltage is too low.

Measure
► Program the counterclockwise rotation: In the
CLPC100 PC software, set the Rotation to
Reverse in the Forward and Reverse Applica-
tion Settings and parameterize the Speed.
If Forward is selected for
Enabled Direction, the
counterclockwise rotation of the
reverse switch has no function.
► Make sure that the operator keeps the start
trigger pressed throughout the entire se-
quence.
► Increase the fastening time.
► Check the fastening sequence to ensure that
the torque shutoff value and/or angle setpoint
are correct. Adjust as necessary.
► Check whether the fastening joint has
changed significantly.
► Make sure that the speed in the stages is cor-
rect.
PC software, select Bright or Dim for Work
Light.
► Parameterize the status light: In the CLPC100
PC software, select Bright or Dim for Status
Light.
► Use a fully charged battery.
► Use a fully charged battery.
If a high torque is needed for a longer period, e.g.
for several turns, the number of rundowns that can
be achieved with one battery charge will be signifi-
cantly reduces.
After 800 charging cycles, the capacity is reduced
to approx. 60%.
► Use new battery.
► Press start switch. If the status light continues
to flash, send the tool to a Sales & Service
Center for repair.
► Allow the tool to cool down. The current run-
down can be terminated, but a new one can-
not be started.
► Change battery.
► Send the tool to a Sales & Service Center for
maintenance.
