count input for contact or edge triggering. The following versions are
available:

0 731 721
Tachometer (1/min):
0 731 202
0 731 722
Time counter (HHHH:MM:SS):
0 731 203
0 731 723

0 731 725
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.
NOTE:
The counter leaves the factory with the default value HI PNP
(f
max
7,5 kHz and positive edge triggered) and unlocked key.
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.
