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 30 Hz and negative edge triggered).

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).
