Parameters
7.8.1.1.1 Valve output
Options:
This parameter defines the type of valve that is connected to the output. The control values re-
ceived (from the internal controller or via the bus) at the valve are converted to the correct output
signal depending on the valve type selected. The dependent group objects Status byte valve A,
Status Control value and Fault: valve output are displayed as long as the output is not deactivated.
In addition, the parameter defines whether the valve outputs for A and B are parameterized sepa-
rately or together. If Thermoelectric (PWM) or Open/Close signal is selected, A and B are two sep-
arate channels. If the Motor-driven (3-point) option is selected, the channels for the actuation of the
valve are combined and parameterized in channel A.
The control value is assigned to the valve in the Application – Application parameters parameter
window. Here it is defined which control value from the controller is to be output on which valve
output.
The FCC/S 1.4.1.1 does not have a second valve output and therefore does not have the Motor-
driven (3-point) option.
• Thermoelectric (PWM): If the Thermoelectric (PWM) option is selected, the output is used for
the connection of thermoelectric valves with PWM actuation. For this purpose the control value
received is converted into a PWM signal. The parameter for setting the PWM cycle time is dis-
played.
• Motor-driven (3-point): If this option is selected, valve outputs A and B are combined to make it
possible to actuate a motor-driven valve drive. Here output A is used to output the opening sig-
nal and output B to output the closing signal.
• Open/Close signal: With this selection, the continuous control value is converted into an OPEN
or CLOSE signal from a parameterized value. The parameter for entering the threshold value is
displayed.
• Deactivated: The output is deactivated.
If a control value has been assigned to the valve in the Application – Application parameters pa-
rameter window, this control value is not output if the output is deactivated.
