Actuators for CAV control units make it possible to motorise the setpoint adjustment, which would otherwise have to be carried out manually on the setting scale. The actuator B70, B72 moves the scale adjustment variably between a minimum and a maximum position.
The setpoint adjustment on the scale is controlled by a 2 - 10 V DC voltage signal. In the B70/B72 actuator, this voltage signal is mapped to the entire angle of rotation 0 - 95° of the actuator.
The scale range to be used for the setpoint specification must be set during commissioning of the CAV control unit using mechanical stops. This limits the scale range that can actually be used. The value of the setpoint signal must be adjusted to the mechanically selected angle range.
The 2 - 10 V DC output signal of the CAV actuator is merely a position feedback and not an actual volume flow rate value. The output signal is mapped to the entire rotation angle 0 - 95° of the actuator.
