Maintenance and repair
Changing the battery of the Compact
System
When switched off, the installed battery has
a service life of approximately four years from
the date of production. The service life in-
creases accordingly when under operation. It
is only subject to self-discharge when under
operation. If the battery has run down, an er-
ror message is generated.
The tightening controller has a built-in bat-
tery-buffered RAM for storing the tightening
results. The data is saved in the RAM due to
the battery if the power fails. The system
clock is also supplied by the battery. The
above mentioned data, as well as date and
time, will be lost if the battery is discharged.
Proceed as follows to exchange the battery:
• Carry out data storage (when the battery is
exchanged, all data stored in the memory
module is lost).
• Open and remove the front cover.
• Remove the four bolts on the display unit.
Hold the display unit and swivel it to the
left. Do not let the ribbon cable tighten or
come loose!

DANGER
Electrical voltages!
Electrocution
Only perform maintenance work on
the tightening channel if the Compact
System has been switched off and
the power plug disconnected. Protect
the system against being switched
on.
Wait until the discharging time (at
least 90 seconds) has elapsed.
CAUTION
Risk of damage to persons and prop-
erty!
To protect the assembly and the sys-
tem components, measures against
damage caused by electrostatic dis-
charge (ESD protection) must be
taken for this assembly work.
