The DULCOMETER
®
D1C does not switch for a certain number of cycles until the sum of the theoretical
switching times exceeds the “min. time“. Then the DULCOMETER
®
D1C switches for the duration of this
total time.
Complete Operating Menu / Description
The switching time of the DULCOMETER
®
D1C (solenoid valve) depends on the actuating variable and the
“min. time“ (smallest permitted operating factor of the connected device).
The actuating variable determines the ratio t
on
/cycle and thus the switching times (see fig. above).
The “min. time“ influences the switching times in two situations:
b) theoretical switching time > (cycle - min. time) and calculated switching time < cycle

The DULCOMETER
