User manual

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 it is in
perfect technical condition. 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 560 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 Over-voltage 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”.
DANGER
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.
2.2 Mounting in a control panel
CAUTION
Mount the device away from heat
sources and avoid direct contact with
corrosive liquids, hot steam or similar.
M
ounting instructions
1. Remove the mounting clip from the device.
2. Insert the device from the front into the panel cut-
out, ensuring the front-panel gasket is correctly
seated.
3. Slide the fixing clip from the rear onto the
housing, until the spring clamps are under
tension and the upper and lower latching lugs
have snapped into place.
2.3 Electrical Installation
DANGER
The device must be disconnected from
the power supply, before any
installation or maintenance work is
carried out. AC-powered devices must
only be connected to the low-voltage
network via a switch or circuit breaker.
Installation or maintenance work must
only be carried out by qualified
personnel.
 In order to comply with fire regulations, the limits of
8A/150VA on the counter must not be exceeded if
a fault occurs.
 During installation, please make certain that the
supply voltage and the output contact wiring is fed
from the same phase of the mains, so as to ensure
that the maximum permitted voltage of 250V is not
exceeded.
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 and control lines. Connect
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 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.
