FunctionsMAGNA, UPEAdditional control and operatingmodesMax. or min. curve dutyThe pump can be set to operate according to the max.or min. curve, like an uncontrolled pump.HThe functions available depend on the pump type andthe expansion module chosen, see overview offunctions on page 9.Max.Constant-pressure controlMin.The pump head is kept constant, independent of thewater requirement.QTM00 5547 4596Grundfos offers additional control and operating modesto meet specific demands.Fig. 10 Max. or min. curvesHThe max. curve mode can be used in periods in whicha maximum flow is required. This operating mode is forinstance suitable for hot-water priority.QTM00 4489 0995HsetThe min. curve mode can be used in periods in whicha minimum flow is required. This operating mode is forinstance suitable for manual night-time duty.Automatic night-time dutyWhen automatic night-time duty has been selected, thepump will change automatically between normal dutyand night-time duty. Changeover between normal dutyand night-time duty takes place as a result of the flowpipe temperature measured by an integratedtemperature sensor.Fig. 8 Constant-pressure controlThe constant-pressure control is recommended insystems with relatively small head losses.Constant-curve dutyRequires the use of an R100 remote control.The pump can be set to operate according to a constantcurve like an uncontrolled pump.If an external controller is installed, the pump is able tochange from one constant curve to another, dependingon the value of the external signal.The automatic changeover to night-time duty takesplace when the temperature sensor registers a flowpipe temperature drop of more than 10-15 C withinapprox. 2 hours. The required temperature drop is aminimum of 0.1 C/min.Changeover to normal duty takes place without a timelag when the temperature has increased by approx.10 C.HAdditional operating modes of twin-headpumpsMin.Fig. 9 Constant-curve dutyQTM03 0551 0205Max.The following operating modes are available for twinhead pumps:Alternating operationPump operation alternates every 24 hours. If the dutypump stops due to a fault, the other pump will start.Standby operationOne pump is operating continuously. In order to preventseizing-up, the other pump will start at a fixed frequency(every 24 hours) and run for a short period. If the dutypump stops due to a fault, the other pump will start.11

ConstructionThe MAGNA/UPE is of the canned-rotor type, i.e. pumpand motor form an integral unit without shaft seal andwith only two gaskets for sealing. The bearings arelubricated by the pumped liquid.The pump is characterised by controller integrated in the terminal box control panel on the terminal box terminal box prepared for optional modules differential-pressure and temperature detection cast-iron, stainless-steel or bronze or pump housing twin-head versions air separator pump housing, types UPE 25-40 A andUPE 25-60 A no external motor protection required.Motor and electronic controllerThe single-phase MAGNA motor is a 4- or 8-pole,synchronous, permanent-magnet motor (PM motor).This motor type is characterised by higher efficiencythan a conventional asynchronous squirrel-cage motor.Pump speed is controlled by an integrated frequencyconverter.The single-phase UPE motor is a 2-pole,asynchronous squirrel-cage motor with radio noise filterto VDE 0875. The terminal box and the motor-pumpunit have been tested in accordance with VDE 0700.The terminal box incorporates a controller. The pumpspeed is calculated via a built-in induction coil on thestator winding.The three-phase UPE motor is a 2-pole, asynchronoussquirrel-cage motor with integrated frequencyconverter.A differential-pressure and temperature sensor formsan integral unit. The sensor is located inside the pumphousing in a channel between suction and dischargesides. Twin-head pumps have two sensors.Pump connectionsThreaded pump connections to ISO 228/1.Flange dimensions to ISO 7005-2/BS4504.Surface treatmentThe pumps are wet-varnished.Colour: NCS40-50R.16MAGNA, UPE

InstallationMechanical installationElectrical connectionMAGNA/UPE is for indoor installation. The pump mustbe installed with horizontal motor shaft.The electrical connection and protection should becarried out in accordance with local regulations.The pump may be installed in horizontal as well asvertical pipes. The pump must be connected to an external mainsswitch.Arrows on the pump housing indicate the liquid flowdirection through the pump. The liquid flow directioncan be horizontal or vertical, depending on the terminalbox position. The pump must always be correctly earthed.The terminal box can be turned to various positions,depending on pump type. This is described in theinstallation and operating instructions.The pump must be installed in such a way that strainfrom the pipework is not transferred to the pumphousing.The pump may be suspended direct in the pipes,provided the pipework can support the pump. If not, thepump must be installed on a mounting bracket or baseplate.To ensure cooling of motor and electronics, thefollowing must be observed: Place the pump in such a way that sufficient coolingis ensured. The temperature of the cooling air must not exceed40 C.18MAGNA, UPE The pump requires no external motor protection.The motor incorporates thermal protection againstslow overloading and blocking (IEC 34-11: TP 211). When the pump is switched on via the mains, thepump will start after approx. 5 seconds.Note: The number of starts and stops via the mainssupply must not exceed 4 times per hour.The pump mains connection must be made as shown inthe diagrams on the following pages.CablesUse screened cables (0.25-1.5 mm2) for external on/offswitch, digital input, sensor and setpoint signals. All cables used must be heat-resistant up to at least 85 C. All cables used must be installed in accordance withEN 60204-1.
