The differential pressure gridin the flow volume control unit allows a differential pressureto be tapped off (∆p w ). The differential pressure is convertedin a transducer with square-root extraction to a linearactual flow volume signal of 0 to 1 bar.The measuring range is adapted to the unit size during theset-up in the factory so that 1.0 bar always corresponds tomax .The actual flow volume can be displayed using a low-capacityindicator unit or a cut-off relay (customer supply) forcontrol of the exhaust air.The flow volume set value is given by the 0.2 to 1.0 barcommand signal from the room temperature controller.The RLP 100 F003 determines the required flow volumeaccording to the characteristic curve shown opposite withinthe limits min and max and compares that with the currentactual value. The damper actuator is controlled correspondingto the control deviation. The flow volume control hasan integral behaviour. The flow volume controllers are usedtogether with Trox actuators.Position dependenceBecause of the membrane’s own weight, the positioning ofthe RLP 100 F003 has an influence on the measurementsignal. The RLP 100 F003 is adjusted for vertical positioningof the membrane. Observe any instructions on the unitlabel referring to fitting position.(20%)0.2 Command signal p 6 1.0 bar3

With theroom pressure controller, the differential pressure betweenthe room pressure and that of a reference room ismeasured and controlled. The flow volume set value ofthe sequence controller is influenced within a limited rangealso by the room pressure controller in addition to themaster controllerFunction descriptionRoom pressure controllerThe measurement of the room pressure 1) is made usingthe static differential pressure principle. One measuringpoint for static pressure is installed in the room to be controlledand one in the reference room. If several roomsare connected together in a pressure cascade, the use ofa neutral reference pressure is recommended, e.g. a corridorthat is free from influence of wind and other pressurefluctuations. These pressures (room pressure differences)are measured using a diaphragm pressure transmitter.The actual value of the room pressure can be tapped offas a pneumatic signal P M . The room pressure set value isadjusted or supplied by an external command signal. Thecontroller compares the required room pressure with thecurrent actual value. This volume variation then effects achange on the flow volume controller.Function of the cascade controlThe flow volume set value is supplied by the room temperaturecontroller and limited to min and max . The setvalue is further offset within certain limits through thesecond command signal input (for room pressurecontroller).The damper actuator is controlled corresponding to thevolume variation. The flow volume controllers are usedtogether with Trox actuators. The adaptation of the controllerto the damper actuator direction of control action(NZ/NO) is made in the factory.1) The room pressure difference is simplified in this documentto room pressure13

The measuringpoints in the room and reference room must be freefrom turbulence (no influence from room flow, no dynamiccomponent p d ).NOTE:If groups of rooms are arranged such that each successiveroom is at a different pressure level, then all transmittersshould function with a common reference pressure, e.g.atmospheric pressure.ReferenceroomRoomRoom pressure controlPrecondition for a room pressure control is that the room possessesthe required air tightness so that the desired roompressure can be obtained from the given flow volume differencebetween supply air and exhaust air. The level of roompressure that results from changes in disturbance variables aswell as the required correction time are dependent on, amongother things, the duct pressures in the supply and exhaust airsystems, the air tightness of the room and theair change rate (flow volume/volume).Room pressure settingThe desired room pressure is set using the ∆p knob.The setting range is from -20 to +20 Pa and -50 to +50 Parespectively.14
