Useful additions
A static differential pressure transducer converts the duct pressure into a voltage signal. The differential pressure actual value is available as a voltage signal. The factory setting is such that 10 V DC always corresponds to the nominal differential pressure (Δp nom). The differential pressure setpoint value is either a constant value or it comes from a setpoint adjuster or from switch contacts. The controller compares the differential pressure setpoint value to the actual value and controls the actuator accordingly if there is a difference. Differential pressure parameters and signal voltage range are stored in the control component. Customers can easily make changes using an adjustment device or a notebook with service tool. If the supply voltage is interrupted or a wire breaks, the spring return actuator moves to the safe position OPEN (NO) or CLOSED (NC) as specified in the order code.

Analogue interface 0 – 10 V or 2 – 10 V DC (operating mode V, F)
The analogue interface can be adjusted for the signal voltage range 0 – 10 V DC or 2 – 10 V DC. The assignment of the duct pressure setpoint value or actual value for voltage signals is shown in the characteristic curves.

Variable operation
Constant value mode
Actual value as feedback for monitoring or tracking control
Override control
For special operating situations, the duct pressure controller can be put in a special operating mode (override control). The following modes are possible: control Pmin, control Pmax, damper blade in the OPEN position, damper blade CLOSED.
Under certain conditions the control can also be suspended (control stop).
Override control via signal input Y
Override control CLOSED via control signal Y
