or screw-type terminals.
It is not allowed to contact the encoder to a direct
current line voltage without protective circuit for
EMC. For cable lengths > 30 m a protective circuit
is always necessary!
When programming the input level to TTL an addi-
tional protective circuit is necessary.
We recommend the installation in an metallic
environment.
Setup and Operation
Only valid for DC-Versions:
When switching on the device in PNP-Mode, a short signal is applied to inputs
A,B,C and the application input.
To suppress the pulse in TTL-Mode each input has to be connected to a resis-
tor of 10 kOhm/0,125W against 0V.
When switching on the device a short signal is applied to the application out-
put.
This pulse, if needed, is possible to suppress by connecting a resistor of 10
kOhm / 0,225 W against 0 V to the application-output.
3.3 Display
After switching on, all segments and characters are illuminated for approx. 2
seconds; then the display changes over to the Display or Programming Mode.
The display is available in five different versions:
Reflectiv: black figures on bright reflecting background
Transflective positive: black figures on back lighted ground

3.6 Programming the Standard Function
The device described here is a multifunctional counter, which can be program-
med for a variety of functions, i.e. pulse counter, tachometer, timer, shift
counter or batch counter functions. The first step is to set the standard func-
tion (the factory setting of the device is the “pulse counter” setting).
Now continue with the programming of the function codes (Chapters 5-9) or

In the function code Programming Mode, the first row shows the name of the
function code in the form of text (7-segment display). The second row shows
the selectable option in a text form, too. By simultaneously pressing the Up
and Down buttons, the display in the first row changes to a numerical display;
after pressing these buttons once again, the display in the second row also
changes to a numerical display. Pressing these buttons for a third time reverts
both rows to the text display again.
Setup and Operation
Attention: With each change among text and
numeric display, the currently activated function
code will return to the factory setting and may
have to be readjusted.
The factory setting is designated with an asterix *.
3.8 Programming the Preset Values
By simultaneously pressing the E + Up, E + Down or E + Shift key you can
change to the Preset programming mode:
Use the shift key in the programming mode to change a setting position. The
selected position will start to flash. Use the shift key again to move by one po-
sition to the right. Then use the UP or Down key to increment or decrement
the position by 1.
Rule for the 6th position: The change from 9 to 0 or 0 to 9 is indicated by a
changing prefix.
Use the E key to leave the programming mode and return to the display mode.
Your entries will be saved.
On leaving the programming mode, the presets are tested for attainability and
recalculated, if necessary, because not all the values may be attained at a
prescaler value of >1. The presetting is then rounded to the next attainable
value.
If no key is pressed for more than 16 seconds in the programming mode, the
counter will automatically return to the display mode. In this case, however,
no entries will be saved except the last value saved with the E-key.
Set the preset value to 0 by pressing Up and Down keys simultaneously.

3.9 Prescaler programming
By pressing the Up + Shift keys simultaneously you can change to the Presca-
ler Programming Mode.
In the Programming mode, the position to be changed is selected by means of
the shift key. The selected position will start flashing. Use the shift key again
to move by one position to the right. Then use the UP or Down key to incre-
ment or decrement the position by 1. It is not possible to save a value of
00,0000. In this case the system will save 01,0000.
Use the E key to leave the programming mode and return to the display mode.
Your entries will be saved.
On leaving the programming mode, all the presets are recalculated because
not all the values may be attained with a prescaler value of >1. Therefore, the
presets have to be checked and corrected as necessary after saving the presca-
ler.
If no key is pressed for more than 16 seconds in the programming mode, the
counter will automatically return to the display mode. In this case, however,
no entries will be saved except the last value saved with the E-key.
Press the Up and Down keys simultaneously to set the prescaler to 01,0000.

General description of multifunctional counter
4 General description of multifunctional counter
The following description is applicable for all standard settings. Special de-
scriptions can be found in the appropriate chapters of this manual.
Factory setting
(Defaults)
Sets all the function codes to the factory settings, i.e. all codes designated
with *.
Prescaler (pulse metering factor):
The “Prescaler” is a multiplier. Each input pulse is multiplied by the adjusted
factor. The display shows integers only. After a reset the counter is completely
reset to 0; this also includes the non-visible value of < 1.
At a prescaler of >1 not all the values are selectable. If invalid Preset values
are selected, the counter will round them up to the next possible value.
Example: PSC 5 cannot select (reach) Preset value 7. In this case, the counter
automatically changes the Preset value to 10).
If the Prescaler is changed, this may also affect the Preset values, which may
have to be changed accordingly.
Adjusting range 0,0001 to 99,9999
The Prescaler is used, for example, to convert counter pulses into meaningful
units, to adapt the units of measurements (e.g. cm-pulses to inch-pulses), or
to compensate for worn out measuring wheels.
Formula: PSC = Desired/nominal display / number of pulses
Example: Flowmeter 173 pulses per 100 liters; display in liters
PSC = 100 / 173 = 0,5780
Example: 1 pulse per cm; display in inch
PSC = 1 / 2,54 = 0,3937

General description of multifunctional counter
Attention: This is only valid for counters and tachometers.
For timers please refer to the special Timer Description.
Display 2. row:
The display of the 2nd row can be programmed as follows:
P 2, P 1, P 0, Prescaler, Batch counter, totalizer or partial sums
(shift counter)
Counter and control inputs:
The counter is fitted with 3 counter and control inputs and, in addition, with
an application input (see below). These inputs are assigned various counter or
control functions by means of function code settings
Input logic:
The input logic can be programmed to NPN or PNP, each at the 8V-level or TTL
level; see Technical Data for the switching threshold.
Reset/Set:
Manual setting via keys (lockable)
Electronic setting via control input (and/or application input)
Automatic programming after reaching the main Preselection
Programmable Power-On Reset
Depending on the function code the counter is:
1.) Reset: reset to 0
P 2 is the main Preset (preselect) value
During unidirectional counting the counter will add up.
or
2.) Set: reset to P 2
Signal 2 at 0
During unidirectional counting the counter will subtract.
For time counting, batch counting or shift counting, it is possible to reset par-
tial sums or the total sum, batch counter or 2nd totalizer individually or at the
same time via the application input.
Independently the counter can be reset to Preset value 0 via the application
input (see below).
Exception: Tachometers do not have a reset/set function
Static/dynamic reset:
Static reset: Reset over the entire pulse width of the reset pulse
Dynamic reset: Reset via the active edge; thereafter, counter operation is
possible independently of the pulse width of the reset pulse.
Exception: Tachometers do not have a reset/set function
Teach input:
Using the Teach Input (application input) the counter status is imported in
Preset 2.
Decimal Point:
The decimal point is only an optical reading assistence on the display and does
not change the value. For example, for a value of 1 pulse per cm, the setting
0,00 makes it easier to read the value in m and cm.
Exception: This does not apply to tachometers and timers.
Please refer to the detailed Tachometer and Timer descriptions.
Input damping
(Attenuation)
The inputs A and B are limited to 60 kHz.
The Application Input is limited to 6 kHz.
Following maximum input frequencies are not to be exceeded:
Phasediscriminator single evaluation: A and B each 30 kHz (TTL 15 kHz)
Phasediscriminator double evaluation: A and B each 30 kHz (TTL 15 kHz)
Phasediscriminator quadruple evaluation: A and B each 15 kHz (TTL 15 kHz)
Unidirectional counting and directional input: Input A 60 kHz (TTL 15 kHz)
Differential counting, summation (totalizing): Input A + B 60 kHz (TTL 15 kHz)
General description of multifunctional counter

36 37
When the application input is used as an additional count input, the above
mentioned input frequencies have to be reduced by the frequency of the ap-
plication input:
If mechanical contacts are triggered (i.e. relays, switches, Reed contacts, etc.),
the input frequency has to be damped (attenuated) to 30 Hz, so as to filter out
bounce pulses.
If damping to 30 Hz is selected, all inputs can be used at 30 Hz.
To reach these values the amplitude thresholds are to be hold.
(See technical data - chapter 10)
Signal
P 1 and P 2 are available as relay changeover contacts and electronic output
signals (PNP).
P 0 is available as an electronic output signal across the application output
(PNP).
If a signal is active, this will be shown on the LCD display.
Optionally, the multifunctional counter can be set to have the display flash if
one or all the preset values are acive.
This is also valid for Preset 0 (if no output has been assigned)
Signaltime:
1.) bistable: Cleared by electronic or manual reset.
P 0 + P 1= bistable – additionally cleared by signal 2
Attention: Signal 2 must not be bistable for automatic reset.
2.) monostable: Up to 9 fixed signal times are available between 0,02s and
10s. In addition, user times can be programmed between 0,01s to 599,99s.
3.) Range signals: active as long as the counter reading is within the adjusted
range.
Signals active on/off
During normal operation the relay is energized if the signal is active.
This behavior can also be inverted (also applicable to the transistor outputs).
General description of multifunctional counter General description of multifunctional counter
Application input/output:
Depending on the standard function, up to 11 (eleven) functions can be assig-
ned to the application input/output. Note, however, that only one of these
functions can be selected.
Further details are given in the Function Code Chapter.
Application – Set to preset 0
Programs the application input to act as a Set Input. The counter is set to Pre-
set 0, independently of the reset via input C or the keyboard.
This function is not available for tachometers.
Application keylock:
All keyboard functions can be locked (latched) individually
(Reset, P 0, P 1, P 2, Prescaler)
Lock mode: release after 10s, complete keylock or
keylock depending on keylock input (application input)
Our advice! After setting up the system, lock
(latch) all the keyboard functions that are not
allowed to be changed by the user.

5 Pulse Counter
5.1 Description of the Pulse Counter
(Supplementing the General Description in Chapter 4)
Counter mode:
The following counter modes can be selected:
Unidirectional counting, adding or subtracting;
Unidirectional counting with directional input;
Differential counting, summation (totalizing) or
phase discriminator (quad) with single, double or quadruple evaluation.
Output signals mode of operation:
1.) coincidence signal: The counter operates in the coincidence mode, i.e.
output signals are activated after reaching the Preset value for the programmed
period of time.
2.) Trail: P 2 and P 0 are under coincidence operation; they operate as descri-
bed in item A.
P 1 is the trail. P 1 is not absolute to 0, but relative to P 2.
If the setting is F8=1, the following will apply:
Signal 1 is returned at P 2 – P 1
Example: P 2=1000, P 1=200, Signal 1 at 800;
If P 1 is negative: P 2=1000, P 1=(-200), Signal 1 at 1200
If the setting is F8=2, the following will be applicable:
Signal 1 is returned at P 2 + und – P 1
(Example: P 2=1000, P 1=200, Signal 1 at 800 or/and 1200)
3.) range signal: VW 1 and 2 are range signals:
Signal 1 is active at a counter reading < P 1 and
Signal 2 is active at a counter reading > P 2
Intermediate cut:
Depending on the application it may become necessary to isolate the main si-
gnal during the reset, e.g. when the first material lengths or certain lengths
showing material defects have to be cut on length-cutting systems.
Pulse counter
Additional totalizer (summation counter)
The additional totalizer sums up all values, even if the main counter is conti-
nually reset. The shift key can be used to switch between the counter reading
and the total sum. The totalizer can only be reset manually.
To do this, select the total sum from the first row; then press the reset keys.
Prescaler Output PSC-out:
The prescaler output is an application output.
With each increase of the counter reading the number of output pulses corre-
sponds to the respective number of increments.
The pulse length of the prescaler output corresponds to a frequency of 500 Hz.
When using the prescaler output the max. count frequency is:
F max = 500 / PSC.
So it is possible that the maximum input frequency can not be reached.
Application counter input add / sub
The application input may be assigned to the Count Up or Count Down func-
tion.
This is a counter input, which is available in addition to the counter mode ad-
justed with F1.
Application Latch/Reset
Latch/Reset is an application input. If the counter is reset via the application
input, the counter reading is held constant. The counter continues to remain
fully functional and operates in the background mode. During the next reset
the current (updated) value will be shown on the display.
