or with plug in screw terminal e. g. 0 731 201 S
1. Programming of the COUNT-Input (all versions)
In order to match your application, the COUNT-Input can be
programmed for high speed (7,5 kHz) or low speed counting (30 Hz
attenuated). Positive or negative edge is programmable as well.

To change the count input configuration:
2. Totalizer version (0 731 201)
Terminal 4 „RESET or Tacho-HOLD" is defined as the Reset-Input.
3. Tachometer version (0 731 202)
The tachometer operates via the gate measuring method. Within the
measuring time of 6 sec, the incoming pulses are counted and recal-
culated in order to display 1/min.
The Terminal 4 „RESET or Tacho-HOLD" is defined as the HOLD-Input
(as long as this Input is active, the actual value in the display is
frozen).
4. Time counters versions (0 731 203 and 204)
The time counters will count as long as the Count-Input (3) is active
(this can be a low or a high signal according to programming in
Chapter 1).
Terminal 4 „RESET or Tacho-HOLD" is defined as Reset-Input.
