Electrical connection

The customer needn´t provide a service line since the divece is ope-
rated mains-independent via an integrated lithium battery and the
sensor is hardwired to the display.
Attention! The service line of the magnetic sensor must
not be ripped open or extended since ebery display has
beed configured explicitly to the connected sensor. There-
fore, it can be replaced in our factory only (e. g. because a
cable break or mechanical distruction of the sensor has
occurd.
Interference and distortion
All connections are protected against the effects of interference. The
location should be selected to ensure that no capacitive or inductive
interferences can affect the encoder or the connection lines! Suitable
wiring layout and choice of cable an minimise the effects of interfe-
rence (eg. interference caused by SMPS, motors, cyclic controls and
contactors).
Necessary measures:
The unit should be positioned well away from cables with interfe-
rence; if necessary a protective screen or metal housing must be
provided. The running of wiring parallel to the mains supply
should be avoided.
Contactor coils must be linked with spark suppression.
Power supply
The automatic monitoring of the storage status ensures safe coun-
ting operation for many years even when the LC display is turned off.
The service life depends essentially on the chosen duty cycle of the
LC display. The following standard values apply (at 23°C):

Attention! As soon as the battery voltage falls below a defi-
ned value, this will be signalled by a symbol on the dis-
play. On this stage, the functioning of the electronic
display is ensured for a limited time. However the battery
should be replaced by Optimum as soon as possible.
2.6.1 Operation and operational modes
The operation of the display or the change to other operating modes
is pefored by means of the three membrane keys on the front side.
Depending on the operating mode the keys may have additional
functions. They are actuated individually and time-dependent.

2.7 Absolute measurement
Following start-up, the electronic display is in the "absolute measure"
operating mode. Here the offset position value is displayed (see cal-
culation of the reading).
Calibration of the measuring system is necessary in the following
cases:
After commissioning
After exchanging the backup battery
If the sensor has been brought into a position outside the moun-
ting tolerances.
The device is calibrated by pressing the
position value to the offset (default=0). Depending on the parameter
"Reset Delay", the key responds to a short pressure or delayed.
