ProMinent DULCOMETER - Functional Description of [Pulse Length (PWM)]

CAUTION!
The [Cycle] is reset when there is no supply voltage
Possible consequence: slight or minor injuries. Material damage.
– Configure the power supply so that it cannot be interrupted
– With critical processes, practically address the possible failure of the timer when
designing your application

Fig. 95: Timer relay
At the end of the (Timer) cycle time, the controller closes the assigned timer relay for a
period of [t on] . [Pause] interrupts the timer. If the clock is visible in the LCD display, then
the OK key can be used to reset the
[Cycle] to the beginning of the cycle. The % figure in
the LCD display indicates the remaining runtime.

Functional description of
[Pulse length (PWM)]
If the output relays are configured as
[Pulse length (PWM)] , then these output
relays emit the pulse length determined by
the controller, to control an actuator (e.g.
motor-driven metering pump, solenoid
valve).
