2/6 Sach-Nr. 2 731 020; Version 1210699WBI
The tico 731.1 is a battery powered LCD-counter with programmable
count input for contact or edge triggering. The following versions are
available:
standard special
Totalizer: 0 731 101 0 731 711
Tachometer (1/min): 0 731 102 0 731 712
Time counter (HHHH:MM:SS): 0 731 103 0 731 713
Time counter (HHHHHH.HH): 0 731 104 0 731 714
or with plug in screw terminal e. g. 0 731 101 S
Energy-save mode:
In order to save energy during delivery and stock, the counter is fac-
tory programmed to low-energy mode and the display shows
„SLEEPING“. To wake up the counter, just press the front button.
Remark: low energy mode cannot be reactivated.
1. Programming of the COUNT-Input
In order to match your application, the COUNT-Input can be program-
med for high speed (7,5 kHz) or low speed counting (30 Hz attenua-
ted). Positive or negative edge is programmable as well.
NOTE:
The counter leaves the factory with the default value LO NPN
(f
max
30 Hz and negative edge triggered).
To change the count input configuration:
2. Totalizer version (0 731 101)
Terminal 4 „RESET or Tacho-HOLD“ is defined as the Reset-Input.
3. Tachometer version (0 731 102)
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 fro-
zen).
4. Time counters version (0 731 103 and 104)
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 the Reset-Input.
