Control signals can be in the range of 2 to 10 VDC (0 to 20 V phasecut also possible). Override control can be achieved by external switches. Several controllers may be connected to one room temperature controller. Supply air/extract air slave circuits are also possible. Static Measuring Principle The volume flow is measured using a membrane pressure transducer. Therefore the VRP is suitable for the control of extract air with contaminants and/or which is dust-loden. Terminal units with painted finish or made of plastic should be considered in such situations. IMPORTANT In critical cases, a material test should be carried out on the terminal unit and membrane pressure transducer, to prove suitability for chemicals and concentrations concerned. Description of Function The volume flow is measured on the static differential pressure principle. The differential pressure sensor in the terminal unit measures the effective pressure (�pe ). This causes a membrane in the pressure transducer to deflect, the movement is detected and converted into a linear pressure voltage signal. The linearisation of the volume flow is carried out in the VRP. The measurement range is set to suit the unit size during factory calibration, so that 10 VDC always corresponds to the unit nominal volume flow rate (‡ nom). The actual volume flow is available as a 2 to 10 VDC signal (U5). The required volume flow is set by the room temperature controller via the control signal within the limits of ‡ min and ‡ max. The VRP determines the required volume flow in accordance with the characteristic shown and compares this with the actual value. The damper actuator is controlled according to the deviation. The Belimo VRP can only operate with the matched Belimo actuators which are optimized for volume flow control. It is not possible to connect other 3-point or 0 to 10 VDC actuators. Gravity Dependency Because of the weight of the membrane the positioning of the VFP affects the measured signal. The VFP is normally calibrated for a vertical position of the membrane, i.e. pressure tube connections above or below horizontal plane. Other installation positions must be specified on order.
