• The shield connection to the equipotential
bonding should be as short as possible and
with a contact area as large as possible
(low-impedance).
• Only connect the shields to the control panel, if
the latter is also earthed.
• Install the device as far away as possible from
noise-containing cables.
• Avoid routing signal or control cables parallel
to power lines.
2.4 Cleaning and maintenance
The front side of the unit should only be cleaned
using a soft damp (water!) cloth. Cleaning of the
embedded rear side is not planned and is the
responsibility of the service personnel or of the
installer. In normal operation, this device is main-
tenance-free. Should the device nevertheless
not operate properly, it must be sent back to the
manufacturer or to the supplier. Opening and re-
pairing the device by the user is not allowed and
can adversely affect the original protection level.
2.5 Start-up
The following points must be checked before
starting up the device:
1. Does the available supply voltage match the
supply voltage of the device?
2. Is the supply voltage connected to the good
terminals of the device?
3. For DC-powered devices, does the supply
voltage respect the polarity?
4. Is the device set and programmed correctly
(function; for counters, max. counting
frequency)?
2.6 Failure possibilities and causes
No display:
• No power supply.
Keys cannot be operated:
• Key lock input is activated
Counter does not count:
• Wrong or reversed wiring of the
counting input
• Setting of an input signal not matching the
pulse generator
• Polarity (NPN/PNP) reversed
• Gate input is active
• No ground connection between the pulse gen-
erator and the counter
• Maximum counting frequency exceeded
• Signal levels do not reach the switching thresh-
old of the counter
• Factor too small
If, despite all, your device still does not operate,
contact your local representative or call us di-
rectly for technical support.
When sending your device back, please attach
a short description of the failure, of the program-
ming and of the connection diagram, in order to
allow us to reproduce a possibly existing defect
and to repair your device as quickly as possible.
3. Setting of the operating pa ra me ters
a. Press both front side keys keys and switch on
the supply voltage or, if the supply voltage is
already on, press both keys simultaneously
during 5 s.
b. The display shows
c. After releasing the keys, the display shows
c1. Hold the left key pressed and press the right
key to leave the programming operation.
c2. Press the right key to switch to
d. Hold the left key pressed and press the right
key to switch to the first parameter.
e. After releasing the keys, the display alternates
between the menu title and the current menu
item setting. After pressing any key, only the
menu item setting is displayed.
f. Pressing the right key, the menu item setting
will be switched to the next value. If figures
are to be input (e.g. when setting the scaling
factor), select first the decade using the left
key, and then set the value using the right key.
