If the units are used to control/monitor machines or processes with
which, as the result of a failure/malfunction or incorrect operation
of the units
– a life-threatening danger,
– health risks or
– a danger of property or environmental damage
could result, then appropriate safety precautions
must be taken!
Do not open the housing of the units or make any
changes to it!
Tampering with the units can have a negative affect on their
operating safety, resulting in dangers!
Do not make repairs on the units! Return defective units to the
manufacturer!
1.3 Installation/commissioning
In case of changes (including in the operating behavior) that
impair safety, shut-down the units immediately.
Installation may only be carried out in accordance with the
procedure described in Chapter 3 "Connecting".
During installation work on the units, the power supply must
always be disconnected. Installation work may only be carried out
by appropriately trained experts.
Max. voltage 250 V terminal - terminal, ground - terminal.
Following proper assembly and installation, the units are ready for
operation. Following commissioning, familiarize yourself with the
use of the units in Chapter 4 "Operator Level".
1.4 Maintenance/repairs

Main counter systems: (PTB-approved)
1 up/down preset counter with totalizer.
Batch counter systems: 1 preset counter, adding.
A key provided at the counter enables switching the display to the
respective counters of the main respectively batch counting
system.
Counter function
Applications
The counter is administrating the inputs of both counting systems
and will react by the programmed output action upon achieving the
set presets respectively limit values.
Thanks to various programming options the device is capable of
many machine monitoring and controlling tasks. Running values and
the set parameters remain even after power failure.
The serial interface allows printout of counter values.
● Interior use for monitoring and control of production machines
and systems.
● In any branches of industry where length measurement is
subject to calibration.
The device must not be used in: explosive areas, medical appliances
as well as in applications explicitly mentioned in the standards of
VDE 0411 part 100.

Litz contact only by means of connector sleeves with insulating
enclosures for reasons of shock protection according to VDE 0411
part 100. Do not otherwise assign contacts that have been left
unassigned ex factory. We recommend to screen all encoder
terminal leads and to ground the shield on one side. Shields on
both sides are recommended in case of RF interference or in case
of equipotential bonding over long distances. The encoder leads
should not be in the same phase winding as the MAINS supply and
the output contact leads.

3.1 Connecting the power supply
For power supply following voltage ranges are available:
AC 115/230 VAC (50/60 Hz)
DC 24 VDC ±10%
Voltage supply Recommended external fuse
115/230 VAC M 125 mA
24 VDC M 400 mA
➜ Assign voltage supply to terminals 2 and 3 according to
diagramm.
DC-voltage 24 VDC:
Connect voltage supply that is free from any interference. Do not utilize the voltage supply for parallel supply of drives, shields, magnetic
valves, etc. Supplying lines must be separated from lines providing
load current.
Fire protection: Operate the instrument using the recommended
external fusing indicated in the terminal diagram. EN 61010 specifies
that 8 A/150 VA (W) must never be exceeded in the event of a fault.
3.2 Assignment signal output „relay contact“
Terminals 4, 5, 6 and 7, 8, 9 are no-potential changeover contacts.
Terminals 10 and 11 are configured as NC or NO contacts in accordance with the purchase order specification. The signal outputs
can be assigned in accordance with the adjoining wiring diagram.
Implementation as a pulse or continuous signal, together with the
pulse time, is effected in the programming mode (lines 31, 32, 33).

➜ Assign terminals 4, 5, 6; 7, 8, 9; and 10, 11 (relay contactoutputs)
accordingly.

3.3 Assignment the signal inputs
Terminals 12 to 17 are AC optocoupler inputs. Terminals 12 (track A)
and 13 (track B) are pulse inputs for the main counter (XP) counting
function.
Terminal 14 is an external reset input for the main counter.
Depending on what is set in the programming mode (line 40),
terminal 15 serves as a starting input for the operating hours counter.
Terminal 16 (track B1) is the pulse input for the secondary counter
(XB). Terminal 17 is the input for resetting the secodary counter.
Programming input logic
Terminal Input Starting current Abschaltstrom
resistance
12 1,65 Kohm > 9 mA, < 16 mA < 0,5 mA
13 1,65 Kohm > 9 mA, < 16 mA < 0,5 mA
14 3,3 Kohm > 5 mA, < 8 mA < 0,5 mA
15 3,3 Kohm > 5 mA, < 8 mA < 0,5 mA
16 1,65 Kohm > 9 mA, < 16 mA < 0,5 mA
17 3,3 Kohm > 5 mA, < 8 mA < 0,5 mA
The main counter (XP) is reset by pplying an external signal (signal
width ≥ 30 ms) at terminal 14; the secondary counter (XP) at terminal
17. While an external signal is present, no counter take place. The
method of resetting is set in the programming mode (lines 29, 30).
Assign terminals 12 to 17 accordingly. The maximum counter
frequency is selected in the programming mode (line 26).
The signal input logic can be programmed by means of a bridge between terminals 18, 19 and 20, in accordance with the table below.
