Model OC1135 is a 5 digit Counter with programmable functions for Quadrature Counter, Up-Down Counter and
Frequency Counter-Tachometer. The instrument is designed for industrial applications for connection to
incremental resolvers, inductive and optical sensors and other electric signals. With three keys a5t the
front the menu can be opened. The menu contains Scaling, Preset, Filter, Sampling Time, Reset Time,
Password and two Set Points. The Counter function can be set for Quadrature Counter, Up-Down
Counter or Tachometer.
Quadrature Counter requires two 90°phase shifted Signals A and B from linear or revolving
incremental resolvers. The counting direction is automatically recognized from the phase of the input
signals. The counter is designed for measuring and positioning applications. The display increments all
edges of the input signals.
Up-Down Counter is designed for bidirectional counting applications. The input pulses are connected to
the input A, the logic level at the input B determines the counting direction.
Additional mode is programmable, in which the counter counts up when the pulses are applied to the
input A and counts down when they are connected to the input B.
Tachometer – Frequency Counter is suitable for measurements of revolutions, speed and other
dynamic frequency based applications. The display can be scaled in required process units. By using
two signal inputs from incremental resolvers, the display can measure bidirectional speed or revolutions.
The measuring time can be set from 0.3 sec to 160 sec. The reset time determines the measurement of
the lowest possible frequency. This time can be set up to 360 seconds, which determines the lowest
frequency of 0.003Hz.
Floating Point Arithmetic permits practically unlimited display capacity. The pre-programmed decimal
point is automatically positioned when the maximum display capacity is achieved. When during the
counting period the display arrives at its full capacity with the decimal point after the last significant digit,
the display shows the overload by UnDEF.
Preset of full 5 digits with decimal point and sign can be selected and entered into the display. The
display starts counting at the Preset.
Scale of the display can be achieved with multiplication and division. The multiplicative constant can be
programmed in full 5 digits with decimal point and sign. The dividing constant is programmable from :1 to
:99999. The scale permits the readings in required process units such as mm, inches, LPM, m/sec etc.

Averaging Filter has programmable constants from 1 to 99. It can be used for noisy signals, disturbed
environments or when the resolver delivers noisy signal due to vibrations.
Last Display Reading remains memorized when the power is switched-off. The display starts to count at
the memorized last reading when the power is switched-on again.
OC1135 is supplied from DC voltage and enclosed in DIN 24 x 48mm cabinet. The connections are with pluggable
screw terminals.
1 FRONT PANEL
The key MENU opens the program menu. The required parameter will be confirmed with ACK. The
parameter magnitude will be set with ACK or SET.
The flashing digit - Cursor – can be positioned with ACK. The Sign and the Decimal Point can de set first
after the cursor is positioned out of the display range and no digit is flashing. With the SET the decimal
point and the sign will be set. The programming is terminated with the key SET and the display return to
the measuring mode.
2 MODES OF OPERATION
The counter permits three mode of operation:
Quadrature Counter (Menu Steps QUAd and Udic)
The instrument permits connection to resolvers or measuring lineals with two 90º phase shifted signals
A, B and zero reset. The display counts with each edge of the signals A an B, thus multiplying the
resolution by 4. The display increments or decrements within the entire range -99999 … 99999. The Up
or Down counting is automatically determined by the phase shift of pulses A and B.
UP-DOWN Counter (Menu Steps Udic and Count)
The pulses to be counted are at the input A whereas the logic level at the input B determines the
counting direction.
UP: B = 0 or open
DOWN: B = 1 (5V … 28V)
Frequency Counter – Tachometer (Menu Steps Udic and tAcho)
The counting pulses are at the input A. The display shows the frequency. By using the scaling facilities,
the display can be used for tachometry, showing RPM, speed or other frequency depending function.
The logic level at the input B determines the sign:
Positive Sign: B = 0 or open
Negative Sign: B = 1 (5V … 28V)

MENU Filt Filter Constant: OFF, FIL 1, FIL 2, … FIL 99.
MENU SPASS Setting of the Password from 20 possible combinations memorized.
MENU StArt Start of the measuring mode.
The key SET terminates the programming mode and starts the measurement. If pressed during the
measuring mode, the display will reset to zero or will be set to the value programmed in the menu step
PrESE.
By selecting the Tachometer tAcho the display shows additional menu steps:
MENU FbASE Tachometer Time Base (Measuring Time in Seconds)
Select with ACK and SET: OFF, 0.22, 0.45, 0.90, 1.8, 3.6, 7.2, 15, 30, 60, 120
The selection OFF is the maximum speed determined by the microcontroller.
MENU ObASE Tachometer-Reset Time (in Seconds)
Select with ACK and SET: OFF, 0.22, 0.45, 0.90, 1.8, 3.6, 7.2, 15, 30, 60, 120
ObASE determines the Reset Time after which the display will set to zero with no pulses
at the input. This has to be considered at low frequency measurements where the ObASE
value has to be set accordingly.
IMPORTANT: The reset time ObASE has always be set at least one step higher than the selected
measuring time FbASE. Measurements of low frequencies require the ObASE value
enough long to prevent the counter not to be reset between two consecutive pulses.

4 SCALE and dSCALE
The input frequency can be scaled to the required reading at the display by the multiplying and the
dividing free programmable constants:
SCALE Multiplicative constant
dSCALE Dividing constant of the SCALE.
4.1 EXAMPLE – QUADRATURE COUNTER
Task: A resolver with 14400 pulses/revolution is used. The display has to show 2.000 after one
revolution.
Solution: Set quAd in the menu.
SCALE Calculation: 2.000 : 14400 = 0.000138888 = 1.38888 : 10000
SCALE Selection: 1.3888 adjust in Menu Step SCALE
SCALE Division: Select 10000 in Menu Step dSCALE
Decimal Point: Select CC.ddd in Menu Step OrdEr
Terminate with the key SET.
5 H-TEST and CALIBRATION
Service and calibration Submenu is available. To enter it, press the key MENU during power-on and hold
it pressed until the display shows HtESt.
The key MENU advances the test. The display segments will be tested, the Set Points SP1 and SP2
activated and the frequency calibrating constant CL can be set. The HtESt can be terminated only by
switching-off the supply.
Calibrating Constant CL: This is a correction constant selectable from -99 to 99. The number at the
display increases as long as the key MENU is kept pressed. When at the same time also the key ACK is
pressed, the number starts decrementing. The CL value of 10 corresponds approx. to 2 increments of
the least significant display digit.
