1. preface
Please read this instruction manual carefully before installation
and start-up. Please observe all warnings and advice, both for
your own safety and for general plant safety. If the device is not
used in accordance with this instruction manual, then the intended
protection can be impaired.
2. Safety instructions and warnings
Please use the device only if its technical condition is perfect. It
should be used only for its intended purpose. Please bear in mind
safety aspects and potential dangers and adhere to the operating
instructions at all times.
2.1 Use according to the intended purpose
The preset counter detects and measures pulses, times and
frequencies up to max. 60 kHz and offers a wide variety of
different operating modes. At the same time, the preset counter
processes programmed presets. Use for any purpose over and
beyond this will be deemed as not in accordance with its intended
purpose and thus not complying with the requirements.
The application area for this device lies in industrial processes
and controls, in the fields of manufacturing lines for the metal,
wood, plastics, paper, glass, textile and other like industries.
Over-voltages at the terminals of the device must be kept within
the limits of overvoltage Category II.
The device must only be operated when mounted in a panel in the
correct way and in accordance with the section
Technical Data
.
Correct operation of the device requires the mandatory use
of the appropriate external safety fuse. Advice concerning the
recommended fuse-protection can be found under
Technical Data
.
The device is not suitable for use in hazardous areas and for areas
excluded in EN 61010 Part 1.
If the device is used to monitor machines or processes in which,
in the event of a failure of the device or an error made by the
operator, there might be the risk of damaging the machine or
causing an accident to the operators, then it is your responsibility
to take the appropriate safety measures.

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 connecting lines! Interference (e.g. from switch-mode
power supplies, motors, clocked controllers or contactors) can be
reduced by means of appropriate cable routing and wiring.
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 0.4 mm²
•
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.
•
Cables and their insulation should be in accordance with the
intended temperature and voltage ranges
