MAGNA3 3 Product range Pump selection Frequently, pumps are selected based on a maximum flow and pressure loss in a system as well as peak efficiency of the pump. For circulators in variable demand systems such as a heating system where the heat load varies with the season and time of day it is more optimal to select a pump for this varying demand rather than one specific duty point. The MAGNA3 has been optimized for variable demand systems.
MAGNA3 3 System application Recommended for most heating systems, especially in systems with relatively large pressure losses in the distribution pipes. See description under proportional pressure. In replacement situations where the proportional-pressure duty point is unknown. The duty point has to be within the AUTOADAPT operating range. During operation, the pump automatically makes the necessary adjustment to the actual system characteristic.
MAGNA3 3 Product range System application If an external controller is installed, the pump is able to change from one constant curve to another, depending on the value of the external signal. The pump can also be set to operate according to the max. or min. curve, like an uncontrolled pump: • The max. curve mode can be used in periods in which a maximum flow is required. This operating mode is for instance suitable for hot-water priority. • The min.
MAGNA3 3 Operating modes Recommended for most heating systems. During operation, the pump automatically makes the necessary adjustment to the actual system characteristic. This setting ensures minimum energy consumption and noise level from valves, which reduces operating costs and increases comfort. Min. Q TM05 2446 5111 Max. H Normal: The pump runs according to the selected control mode. Note: The control mode and setpoint can be selected even if the pump is not running in "Normal" mode.
MAGNA3 3 Product range FLOWADAPT Proportional pressure The typical pump selection is based on required flow and calculated pressure losses. Pumps are often oversized. To adjust for "oversized" pumps, valves are typically used to increase the resistance and thus reduce the flow. The FLOWADAPT function reduces the need for a pump throttling valve. Note: This function cannot eliminate the need for balancing valves in heating systems.
MAGNA3 Constant temperature Differential Temperature In heating systems with a fixed system characteristic, for example domestic hot-water systems, the control of the pump according to a constant return-pipe temperature is relevant. This control mode ensures a constant differential temperature drop across a heating system. The pump should be installed in the flow pipe so the built-in sensor measures the fluid temperature going out to the load.
MAGNA3 3 The pump can be set to operate according to a constant curve, like an uncontrolled pump. See fig. 18. The desired speed can be set in % of maximum speed in the range from 25 to 100 %.

MAGNA3 3 Product range Additional operating modes for multi-pump setup Multi-pump function The multi-pump function enables the control of single-head pumps connected in parallel and twin-head pumps without the use of external controllers. The pumps in a multi-pump system communicate with each other via the wireless GENIair connection. A multi-pump system is set up via a selected pump, i.e. the master pump (first selected pump). The multi-pump functions are described in the following sections.
MAGNA3 Factory setting "Status" menu The pumps have been factory-set to AUTOADAPT without Automatic Night Setback. This menu shows the status of the pump and system as well as warnings and alarms. Note: No settings can be made in this menu. This menu offers the following: • Operating status • Pump performance • Power and energy consumption • Warning and alarm • Heat energy meter • Work log • Fitted modules • Date and time • Pump identification • Multi-pump system.
MAGNA3 3 Heat energy meter The "Assist" menu guides the user through the setting of the pump. In each submenu, the user is presented with a guide that assists throughout the setting. This menu offers the following: • Step-by-step instructions in how to set up the pump. • A short description of the six control modes and recommended applications. • Assistance in fault correction.
MAGNA3 Grundfos Eye Communication The Grundfos Eye at the top of the control panel is a pump status indicator light providing information about the pump operating status. The indicator light will flash in different sequences and provide information about the following: • power on/off • pump warnings • pump alarms • remote control. The function of the Grundfos Eye is described in detail in the installation and operating instructions.
MAGNA3 3 Product range Wireless GENIair The pump is designed for multi-pump connection via the wireless GENIair connection. The built-in wireless GENIair module enables communication between pumps and with the Grundfos GO Remote without the use of add-on modules. • Multi-pump function. See section Multi-pump function. • Grundfos GO Remote. See section Grundfos GO Remote.

MAGNA3 3 Module Fieldbus protocol Description Functions GENIbus The CIM 050 is a Grundfos communication interface module used for communication with a GENIbus network. The CIM 050 has terminals for the GENIbus connection. The CIM 100 is a Grundfos communication interface module used for communication with a LonWorks network. The CIM 100 has terminals for the LonWorks connection. Two LEDs are used to indicate the actual status of the CIM 100 communication.
MAGNA3 4 Operating conditions 4.
MAGNA3 4 The MAGNA3 incorporates a differential-pressure and temperature sensor. The sensor is located in the pump housing in a channel between the suction and discharge ports. The sensors of twin-head pumps are connected to the same channel and the pumps therefore register the same differential pressure and temperature. Via a cable, the sensor sends an electrical signal for the differential pressure across the pump and for the liquid temperature to the controller in the control box.
MAGNA3 5 Construction 5. Construction The MAGNA3 is of the canned-rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid.

MAGNA3 6 Installation 6. Installation Mechanical installation Insulating shells The MAGNA3 is designed for indoor installation. The pump must be installed with horizontal motor shaft. The pump may be installed in horizontal as well as vertical pipes. The insulating shells supplied with single-head MAGNA3 pumps are for heating systems and should be fitted as part of the installation. Insulating shells for air-conditioning and cooling systems are available as an accessory.
MAGNA3 6 If the pump is connected to an electric installation where an earth leakage circuit breaker (ELCB) is used as an additional protection, this circuit breaker must trip when earth fault currents with DC content (pulsating DC) occur.
MAGNA3 6 Installation Digital inputs Min. curve The digital input can be used for external control of start/stop or forced max. or min. curve. Note: If no external on/off switch is connected, the jumper between terminals Start/Stop (S/S) and frame ( ) should be maintained. This connection is the factory setting. H Normal duty Q H Min. curve M A M I S/S Q TM05 3343 1212 Relay outputs The pump has two signal relays with a potential-free changeover contact for external fault indication.
MAGNA3 6 1 24V IN Vcc Signal 2 TM05 2947 1212 The analog input can be used for the connection of an external sensor for measuring temperature, pressure, flow or other parameter. The analog input can also be used for an external signal for the control from a BMS system or similar control system. The electrical signal for the input can be 0-10 VDC or 4-20 mA. The selection of electrical signal (0-10 V or 4-20 mA) can be changed on the control panel or with the Grundfos GO Remote.
MAGNA3 7 Accessories 7. Accessories Insulating for air-conditioning and cooling systems Location of CIM module For cooling applications, if the supplied insulation shell is to be used then a silicon sealant must be liberally applied to the inside of the insulation shell to ensure all air gaps are eliminated between the shell and pump housing to prevent condensation inside the shell. The CIM module is fitted behind the front cover. See fig. 45.
