Digital input
If the input signal is activated with a logical signal (15 to 30 V DC) and the Polarity is set to
Active high level, the meter carries out an activity selected in the menu Input function:
● Zero point adjustment
– Starts the automatic zero point adjustment. This function employs the existing
configurations and presumes that the process conditions are prepared for the zero
point adjustment routine
● Reset totalizer
– Resets one of the internal totalizers 1, 2 or 3 (depending on configuration)
● Reset all totalizers simultaneously
● Freeze process values
– Freezes all currently measured values in the display and outputs
● Force process values
– Forces all outputs to adopt the value selected in the menu. If the value 100% is
selected, the current output will show 20 mA and the frequency output will show
10.000 kHz when the external output is activated
Note
Changing polarity
Changing the polarity triggers the signal input to exec
ute the set functionality.
