Further special functions
Connection to the PC software
The lock has an additional mini
-
USB interface on the input unit.
The lock can be programmed via this interface using the PC soft-
ware available as an accessory. The following functions are avai-
lable when using the additional PC software: a) Reading out au-
dit b) Programming the lock settings using software For further
details on this refer to the operating instructions of the PC soft-
ware.
Additional functions via the signal input
The lock has an option which allows implementing one of the
additional functions via the signal input according to 10.8. The
assignment of the signal inputs is described in the installation
manual of the lock. The functions can only be activated with the
optional PC software. The operating behaviour of the lock with
different input signals active is.
Additional functions via the signal outputs
The lock has 2 signal outputs: Details on assignment of the out-
puts are given in the installation manual. The following outputs
are available:
a) Silent alarm.
b) Microswitch for bolt monitoring, no additional programming
possible.

Battery replacement
Do not apply force and avoid touching
electronic components! You could destroy the lock. For battery
replacement the rotary handle of the lock must be dismounted.
Since the rotary handle can be inserted in steps of 90 ° , first,
always note the position of the rotary handle for the assembly
later (e.g. using an adhesive tape on the input unit to mark the
position of the mark on the rotary handle). Insert the enclosed
Allen wrench up to the stop into the hole on the lateral wall of
the input unit as shown in Fig. 6.1. Pull out the rotary handle to
the front from the input unit (see fig. 6.2) and remove the Allen
wrench. Then unscrew the screw in the handle recess (see fig.
6.3). After that the top part of the input unit can be moved as
shown in fig. 6.4 and then it can be removed to the front (see
fig. 6.5). The 2 batteries are located on the base part of the in-
put unit and can be replaced now as shown in fig. 6.6. Only
batteries of type AAA can be used. It is highly recommended to
use high
-
quality brand batteries and replace them as a precauti-
on every 24 months at the latest. After the battery replacement
mount the input unit on the base part from the front in the or-
der reverse to the one described above and move it laterally
until it engages and the red LED turns off. Then attach the screw
to secure the top part. Now attach the rotary handle in the posi-
tion in which it has been mounted before dismounting (to do so,
use the marking mentioned above). If the mounting is correct,
the rotary handle can no longer be removed. Remove the mar-
king (in this way). Finally, the take
-
off contact message must be
neutralised (see chapter 9.6). It can be performed only by the
master. Battery replacement (example above: the input unit
keyboard is located to the right of the rotary handle. For other
mounting positions proceed correspondingly):
Undervoltage indication w and the battery must be replaced
promptly. As soon as the undervoltage indication is displayed,
the lock can still be opened, but no reprogramming is possible
until after the battery replacement. Furthermore, an audit entry
is performed. As soon as the battery is almost completely ex-
hausted, no opening can be performed and every key stroke is
acknowledged with an undervoltage signal.
Permanent power supply If necessary, along with the battery power supply the lock can also be supplied with voltage permanently. The
following options are available for this purpose: a) Power supply via the intruder detection system and the alarm box (art. no.
3001001550) b) Power supply via the alarm box (see above) for connection to the signalling equipment without power supply option via
the additional 12V power supply unit at the alarm box (see above) art. no. 3002501230 c) If the lock is used without any signalling
equipment: 9V power supply unit can be connected directly at the lock, art. no. 3002501220 Even with the permanent power supply the
batteries must still be inserted into the input unit because otherwise the lock cannot be opened by means of the code entry in case of
power failure or a fault of the permanent power supply. The undervoltage indication is displayed in case of the permanent power sup-
ply failure and exhausted battery. The batteries and the permanent power supply should be checked as soon as possible in this case.
