For protection against shock hazards as specified in VDE 0411 part
100, stranded conductors may only be connected using wire end
ferrules with insulating caps. Terminals which are not assigned in
the factory must not be otherwise assigned by the user. We
recommend shielding all encoder connecting leads and earthing
the shield at one end. Earthing at both ends is recommend to avoid
RF interference or if equipotential bonding conductors are installed
over long distances. Encoder connecting leads should not be laid in
the same trunking as the mains power supply cable and output
contact leads.
3.1 Connecting the power supply
AC voltage connection It is possible to switch between two different alternating voltage
ratings (see adjoining table) by means of the voltage selector switch
at the side of the unit. The higher of the two alternating voltage
ratings (48V or 230V) is preset by the factory.
➜Set the required alternating
voltage with the voltage
selector switch.
➜Connect the alternating
voltage supply to terminals 2
and 3 in accordance with the
counter wiring diagram.
DC voltage connection Connect an interference-free power supply, i.e. do not use it for the
parallel connection of drive systems, contactors, solenoid valves, etc.
➜Connect the DC voltage in accordance with the counter wiring
diagram.
Fire protection: Operate the instrument using the recommended
external fusing indicated in the terminal diagram. VDE 0411
specifies that 8A/150 VA(W) must never be exceeded in the event
of a fault.
3.2 Assignment signal output „relay contact“
Terminals 4, 5 and 6 form a no-potential changeover contact, which
can be assigned as a pulse or continuous contact in accordance with
the adjoining wiring diagram.
Implementation as a pulse or continuous signal is effected via DIP-
switch 2 and in the programming mode, line 12 (see 3.6). The pulse
time is programmed in the programming mode, line 2.

The user is responsible for ensuring that a switching load of
8A/150 VA (W) is not exceeded in the event of a fault. Internal spark
suppression by means of two zinc oxide varistors (275 V). The
output relays of the instrument (1 relay or several) may only be
disengaged in total 5 x per minute at the most. Admissible clicks
according to interference suppression standard EN 55011 EN
50081-2 for the industrial sector. In case of a higher switching rate,
the operator must take care of interference suppression on the spot
and under his own responsibility by observing the load to be
switched.
➜Assign terminals 4, 5 and 6 (relay contact outputs) accordingly.
3.3 Assignment electronic output
The electronic output (terminal 10) is pre-programmed by the factory
as an NPN or PNP switching transistor (open collector) in accordance
with the purchase order specification. The output is coded as a pulse
or continuous signal at DIP-switch 2.
The electronic output is not short-circuit proof.
➜Assign terminal 10 accordingly.
3.4 Assignment signal input
Terminals 7, 8 and 9 are AC optocoupler inputs. Terminals 7 (track A)
and 8 (track B) are pulse inputs for the counting function.
Terminal 9 is the external reset input.
The counter is reset by applying an external signal (signal width
≥30 ms) at terminal 9 (see part 5, programming line 7).
➜Assign terminals 7, 8 and 9 accordingly.
The maximum counting frequency is set via DIP-switch 3
(see 3.6). For suitable pulse generators, see the encoder Catalogue.

3.6 Establishing basic settings (DIP-switches)
The basic settings are established by means of DIP-switches, the
positions and effects of which are described below. The DIP-
switches are located on one side of the counter housing, together
with a setting diagram.
➜Set DIP-switches as required before installing the unit.
●All switches are set to OFF by the factory before delivery.
3.6.1 Setting operating modes (DIP-switch 1)
Adding mode
DIP-switch 1 OFF The counter adds from zero to the preselected number. An external,
manual or automatic reset causes the counter to revert to zero or to
the programmed start count value.
Subtracting mode
DIP-switch 1 ON The counter subtracts from a preselected number to zero or to the
programmed start count value. An external, manual or automatic
reset causes the counter to revert to the preselected number.
For details of totalizing, up/down and differential counting, see 5.1.
