7.8.1.1.1.1
Selection of Thermoelectric (PWM)
7.8.1.1.1.1.1
—
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:
Closed
Open
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.
7.8.1.1.1.1.2
—
Dependent Parameter
PWM cycle time
Options:
10…180…900
For setting the cycle time for the pulse width modulation.
7.8.1.1.1.1.3
—
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:
10…60…900
With this parameter, a time is set in seconds that the connected valve requires to move from posi-
tion 0 % (valve closed) to position 100 % (valve fully open), or the valve requires to move from
100 % to 0 %.
Note
The time should be taken from the technical data of the valve, and it corresponds with the total
runtime.
