At the end of the (Timer) cycle time, the DULCOMETER
®
D1Cb / D1Cc closes the corre‐
sponding timer relay for the duration of
"t on" (Timer). "Pause" interrupts the timer. If the
clock is visible on the LCD display, then the timer can be reset to the beginning of the
cycle using the enter key. The % specification on the LCD display indicates the remaining
runtime.

The switching times of the relay (solenoid valve) depend on the control value and on the
"minimum time" (smallest permissible switching time of the connected device). The con‐
trol value determines the ratio ton/cycle and thus also the switching times.
