3 Product features Principle of operation he actuator is comprised of three components: characterised control valve (CCV), measuring pipe with volumetric flow sensor and the actuator itself. he adjusted 1%). he actuator control can be either communicative or analogue. he medium is detected by the sensor in the measuring pipe and is applied as the flow value. he measured value is balanced with the setpoint. he actuator corrects the deviation by pressure through the final controlling element (see volumetric flow curves). With the supply voltage the integrated condensors will be charged. Interrupting the supply voltage causes the valve to be moved to the selected emergency setting position (POP) by means of stored electrical energy. Flow rate curves Δp3 Δp1 < Δp2 < Δp3 Δp2 Δp1 α Pre-charging time (start up) he capacitor actuators require a pre-charging time. his time is used for charging the capacitors up to a usable voltage level. his ensures that, in the event of an electricity interruption, the actuator can move at any time from its current position into the preset emergency setting position (POP). he duration of the pre-charging time depends mainly on following factors: Duration of the electricity interruption PF delay time (bridging time) ypical pre-charging time 3 [s] 25 PF [s] 1 s 3 [s] s 2s s [d] 12 [d] = Electricity interruption in days [s] = Pre-charging time in seconds PF[s] = Bridging time Calculation example: Given an electricity interruption of 3 days and a bridging time (PF) set at 5 s, the actuator requires a pre-charging time of 14 s after the electricity has been reconnected (see graphic). elivery condition (capacitors) PF [s] [d] [s] he actuator is completely discharged after delivery from the factory, which is why the actuator requires approximately 2 s pre-charging time before initial commissioning in order to bring the capacitors up to the required voltage level. 67 3

4 Product features Emergency setting position (PP) rotary knob he «Emergency setting position» rotary knob can be used to adjust the desired emergency setting position (POP) between and 1% in 1% increments. he rotary knob allways refers to the adapted angle of rotation range. In the event of an electricity interruption, the actuator will move into the selected emergency setting position (POP). Settings: he rotary knob must be set to the «ool» position for retroactive settings of the emergency setting position (POP) with the BELIMO service tool MF-P. Once the rotary knob is set back to the range 1%, the manually set value will have positioning authority ridging time Electricity interruptions can be bridged up to a maximum of 1 s. In the event of an electricity interruption, the actuator will remain stationary in accordance with the set bridging time. If the electricity interruption is greater than the set bridging time, then the actuator will move into the selected emergency setting position (POP). he bridging time set ex-works is 2 s. his can be modified on site in operation with the use of the BELIMO service tool MF-P. Settings: he rotary knob must not be set to the «ool» position! Only the values need to be entered for retroactive adjustments of the bridging time with the BELIMO service tool MF-P. ransmission behaviour HE Heat exchanger transmission behaviour Depending on the construction, temperature spread, medium and hydraulic circuit, classical type of temperature control, an attempt is made to maintain the control signal proportional to the power Q (Curve 2). his is achieved by means of an equalpercentage valve characteristic curve (Curve 3)

5 Product features Control characteristics he velocity of the medium is measured in the measuring component (sensor electronics) and converted to a flow rate signal. he positioning signal corresponds to the power Q via the exchanger, the volumetric flow is regulated in the EPIV. he control signal is converted into an reference variable w. he momentary control deviation forms the positioning signal 1 for the actuator. he specially configured control parameters in connection with the precise flow rate sensor ensure a stable quality of control. hey are however not suitable for rapid control processes, i.e. for domestic water control. 5 displays the measured volumetric flow as voltage (factory setting). As an alternative, 5 can be used for displaying the valve opening angle. It is always in = 5 V. 1.

Opening valve he valve remains closed until the volumetric flow required by the positioning signal after this value has been exceeded. Closing valve he control along the valve characteristic curve is active up to the required flow rate of variable, then the valve will close. [m 3 /h] 1% Converter for sensors Parameterisable actuators Positioning signal inversion Hydraulic balancing Manual override High functional reliability [V].5% 1% 1% Connection option for a sensor (active sensor or switching contact). he MP actuator serves as an analogue/digital converter for the transmission of the sensor signal via MP-Bus to the higher level system. he factory settings cover the most common applications. Input and output signals and other parameters can be altered with the PC-ool MF-P or with the Service tool ZH. his can be inverted in cases of control with an analogue positioning signal. he inversion causes the reversal of the standard behaviour, i.e. at a positioning signal of With the Belimo-ools, the maximum flow rate (equivalent to 1% requirement) can be adjusted on-site, simply and reliably, in a few steps. If the device is integrated in the management system, then the balancing can be handled directly by the management system. Manual control with push-button possible - temporary. he gear is disengaged and the actuator decoupled for as long as the button is pressed. he actuator is overload protected, requires no limit switches and automatically stops when the end stop is reached. 6 67

7 Product features Home position he first time the supply voltage is switched on, i.e. at the time of commissioning, the actuator carries out an adaption, which is when the operating range and position feedback adjust themselves to the mechanical setting range. After this process the actuator moves into the required position in order to ensure the flow rate defined by the positioning signal. ccessories escription ype Gateways Gateway MP for BACnet MS/P, AC/DC 24 V K24BAC Gateway MP to Modbus R, AC/DC 24 V K24MOD Gateway MP for LonWorks, AC/DC 24 V, LonMark-certified K24LON Gateway MP to KNX/EIB, AC/DC 24 V, EIBA certified K24EIB escription ype Electrical accessories Connecting cable 5 m, A+B: RJ12 6/6, o ZH/ZIP-SB-MP ZK1-GEN Connection cable 5 m, A: RJ11 6/4, B: Free wire end, o ZH/ZIP- ZK2-GEN SB-MP MP-Bus power supply for MP actuators, AC 23/24V for local power ZN23-24MP supply Connecting board MP bus suitable for wiring boxes EX-WR-FP..-MP ZFP2-MP ervice ools escription Service ool, for MF/MP/Modbus/LonWorks actuators and VAV- Controller Belimo PC-ool, software for adjustments and diagnostics Adapter to Service-ool ZH ZIP-SB-MP interface ype ZH MF-P MF-C ZIP-SB-MP Electrical installation! otes Wiring diagrams AC/DC 24 V, modulating + Operation on the MP-Bus + DC ()2 1 V DC 2 1 V Sensor MP Cable colours 1 = black 2 = red 3 = white 5 = orange Cable colours 1 = black 2 = red 3 = white 5 = orange 67 7

10 Installation notes Recommended installation positions he ball valve can be installed upright to horizontal. he ball valve may not be installed in a hanging position, i.e. with the stem pointing downwards. 9 9 Mounting position in the return Water quality requirements Maintenance Installation in the return is recommended. he water quality requirements specified in VDI 235 must be adhered to. Belimo valves are regulating devices. For the valves to function correctly in the long term, they must be kept free from particle debris (e.g. welding beads during installation work). he installation of suitable strainer is recommended. Ball valves, rotary actuators and sensors are maintenance-free. Before any kind of service work is carried out on the actuator, it is essential to isolate the rotary actuator from the power supply (by unplugging the electrical cable). Any pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow everything to cool down first if necessary and reduce the system pressure to ambient pressure level). he system must not be returned to service until the ball valve and the rotary actuator have been properly reassembled in accordance with the instructions and the pipeline has been refilled in the proper manner. low direction Inlet section he direction of flow, specified by an arrow on the housing, is to be complied with, since otherwise the flow rate will be measured incorrectly. In order to achieve the specified measuring accuracy, a flow-calming section or inflow section in the direction of the flow is to be provided upstream from the measuring pipe flange. Its dimensions should be at least 5x DN. DN L min x 15 mm = 75 mm 2 5 x 2 mm = 1 mm 25 5 x 25 mm = 125 mm 32 5 x 32 mm = 16 mm 4 5 x 4 mm = 2 mm 5 5 x 5 mm = 25 mm L 5 x DN 1 67
