1.5 Mounting instructions
– Remove the mounting clip from the device.
– Insert the device from the front into the panel
cut-out, ensuring the front-panel gasket is cor-
rectly seated.
– Slide the fixing clip from the rear onto the hous-
ing, until the spring clamps are under tension
and the upper and lower latching lugs
1.6 Electrical Installation
This device is powered by the mains
!
voltage! It must be disconnected from
the power supply, before any installa-
tion or maintenance work is carried out.
AC-powered devices must only be con-
nected to the low-voltage network via a
switch or circuit breaker. Installation or
maintenance work must only be carried
out by qualified personnel.
– Correct operation of the device requires the
mandatory use of the appropriate external
safety fuse. Advice concerning the recom-
mended fuse protection can be found in the rel-
evant instruction manual.
In order to respect the fire protection regula-
tions, 8 A/150 VA shall not be exceeded on the
counter in case of a defect!
– Do not wire the terminals of the device that are
not used.
– The pin assignment of the connectors, as well
as the maximum admissible values, must obliga-
torily be observed.
– During installation, make sure that the supply
voltage and the wiring of the output contacts (if
any) are powered by the same mains phase, in
order not to exceed the max. voltage of 250 V!
The indications of the Instructions manual must
obligatorily be adhered to!
– If the device is equipped with a PE connection,
the latter must obligatorily be connected with a
low impedance.
– An EMC-compliant installation is a prerequisite
to reach EC conformity.
1.7 Advice on noise immunity
All connections are protected against external
sources of interference. The installation location
should be chosen so that inductive or capacitive
interference does not affect the device or its con-
necting lines! Interference (e.g. from switch-mode
power supplies, motors, clocked controllers or
contactors) can be reduced by means of appropri-
ate cable routing and wiring.

1.8 Measures to be taken:
– Use only shielded cable for signal and control
lines.
– Connect cable shield at both ends.
– The conductor cross-section of the cables
should be a minimum of 0.14 mm².
– The shield connection to the equipotential bond-
ing should be as short as possible and with a
contact area as large as possible (low-imped-
ance).
– Only connect the shields to the control panel, if
the latter is also earthed.
– In case of problems due to ground loops, the
shield is to be connected to the reference
ground, on the reception side, with low imped-
ance and, on the emission side, via a capacitor
of approximately 100nF.
– Install the device as far away as possible from
noise-containing cables.
– Avoid routing signal or control cables parallel to
power lines.
– Cables and their insulation should be in accor-
dance with the intended temperature, voltage
and power ranges. The standards of the respec-
tive countries apply.
1.9 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 fre-
quency)?
1.10 Failure possibilities and causes
No display:
- No power supply.
Impossible to use the keys:
- Key lock input 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 active
- No ground connection between the pulse gener-
ator and the counter
