7.9.1.1

Selection of Thermoelectric (PWM)

7.9.1.1.1 —
Dependent parameter
Valve drive operating principle, de-energized
This parameter is visible if, in the Valve output parameter, the Thermoelectric (PWM) or Open/Close signal
option has been selected.
Options:
This parameter determines the function of the valve drive.
•
Closed: If no current flows in the valve drive, the valve is closed. If current flows in the valve drive,
the valve opens.
•
Open: If no current flows in the valve drive, the valve opens. If current flows in the valve drive,
the valve then closes.
7.9.1.1.2 —
Dependent parameter
PWM cycle time
Options:
For setting the cycle time for the pulse width modulation.
7.9.1.1.3 —
Dependent parameter
Valve drive opening/closing time
This parameter is visible if, in the Valve output parameter, the Thermoelectric (PWM) or Open/Close signal
option has been selected.
Options:
With this parameter, a time is set in seconds that the connected valve requires to move from position 0 %
(valve closed) to position 100 % (valve fully open), or the valve requires to move from 100 % to 0 %.
The time should be taken from the technical data of the valve, and it corresponds with the total runtime.
