By selecting the input type, the way the device counts with the signals from the input channels is selected.
There are 9 different counting options. How they work is described below.
In order to select counter type, pressed to prg button at operation mode. Found to Cnt_typ menu with up-
down button and pressed to prg button then bottom row choice flashes. Make the selection with up-down
button and saved value by prg button. Then return with rst button to operating mode.

Provides accurate display of sensors with different resolutions by entering the multiplier value.
By way of example, 0,025 constant value is entered to Const Menu for the 25 micron-sensor or 0,005
constant value for 5 micron-sensor. So when sensor moves 100mm, value of 100 is displayed on the
screen.
In order to set to Conts Menu, pressed to prg button while operating mode and ound to Const Menu with
using up-down button. When pressed to prg button (While being cons menu), the right-hand digit of

bottom row flashes. Set to wanted value with up-down button. Digit moves to the left while pressed to prg
button. Then pressed to prg button again, this digit flashes. Digit position is set with up-down button. You
press again prg button, the digit is continuously flashing. Therefore the constant value is entered in. If you
want to exit without saving, you can back to operating mode with rst button.
Resolution of the value shown on the display is set here. This change is done by changing position of the
point on the screen. In order to changed position of the point, pressed to prg button at operating mode
and found point menu with up-down button. The point is flashing when pressed to prg button; you can set
position of the point with up-down button. Then you can save them with prg button. Return to operating
mode with rst button.
The input frequency can be filtered to prevent undesired interference. Above frequencies of the value
selected in the in_freg menu are not detected by the counter.
In operation mode, press prg button to select input frequency. The in_freg menu is located with the up and
down keys. When the prg button is pressed, the selection in the bottom row flashes. The desired selection
is set with the up-down button and saved with the prg button. Return to operating mode with Rst button.

The value entered is in seconds after the point. If the value is zero, the display shows hold. In this case, the
relays remain drawn as long as they exceed the set value.
Tout menus allow role output times according to entered times. If entered to time as zero, writes hold on
the screen. Thus situated, relays will be active during the set value is exceeded. In order to entered output
time, if you press to prg button, found tout1 or tout2 menus with up-down button. When press prg button,
the right-digit of bottom row flashes. Its value is set with up-down button. Each press of the button moves
to the left in a digit. Then you can save them. Therefore point is fixed.
Out1 and out2 menus allow positions of the relays. The relay is inactive at Nclose option, active while
reached set point. And also the relay is active at Nopen option, it will be inactive while reached set point.
While hold input is active, value on the screen is fixed when coming the signal of hold input. If signal of
hold input isn't cut, counting can not to be continued. While you select the hold input, also select the edge
you will make reset on. You can select one of Rising and falling edges. If you want to hold off Input, select
to off option. In order to select to Hold Input, pressed to prg button at operating mode and found hold

The used sensor type can be select from this menu. The sensor output signal is selectable as NPN or PNP.
In order to selected sensor type, pressed to prg button at operating mode and fount S.typ menu with up-
down button. When prg button is pressed, options will flash and made the selection with up-down button.
Then save it by prg button and return with rst button to operating mode.
Factory menu enables to return the first fabrication settings of device. At this situated, all device setting
will change and for this reason important settings should be saved previously. Device will require the
password for returning to factory defaults and this password is 454. In order to return to factory defaults,
pressed to prg button at operating mode and found to factory menu with up-down button. When prg
button is pressed at menu screen, The right-digit of bottom row is flashing and changed value with up-
down button. When pressing to prg button, moves to the left in a digit and you can set it as 454 and press
to prg button. So device will return to factory defaults..
Password security enables that unauthorized persons is prevented to change the parameters of the menu.
If Code-in menu is on position, you can enter to device’s menu and password is required for any setting
changes. If the password is wrong, you cannot change anything. While Code_in menu is off, the password
protection is not active. If Code_in menu is on, recode is added to menu titles. In order to turn on Code-in
menu, pressed to prg button at operating mode and found Secu Menu with up-down button. Then save it
