3 ydro Multi-E. Introduction Grundfos ydro Multi-E booster systems are designed for the transfer and ressure boosting of clean water in laces such as blocks of flats hotels industry hositals schools. Grundfos ydro Multi-E booster systems consist of two to four Grundfos CRE, CRIE ums or two or three CME-A, CME-I ums connected in arallel and mounted on a common base frame rovided with all necessary fittings. As standard, the ydro Multi-E is sulied with the following: base frame ums suction and discharge manifolds ressure switch as dry-running rotection one or two discharge-ressure sensors, deending on um size non-return valves, one er um isolating valves, two er um ressure gauge diahragm tank breaker box. On delivery, the Grundfos ydro Multi-E booster system is factory-tested and ready for oeration. ydro Multi-E, 0.7 to. kw The ums incororated in this ydro Multi-E system are fitted with the new-generation MGE motors which are ermanent-magnet motors with a high-efficiency frequency converter. The motors ensure an even higher efficiency than the revious version of the booster system. The MGE motors have a total efficiency which exceeds the IE Suer Premium Efficiency level defined for fixed-seed motors. The ydro Multi-E with ums in this range offers additional functions: multi-master function ie-filling function redefined setoint external setoint influence limit-exceeded function. ydro Multi-E,.0 to 7.5 kw The ydro Multi-E with ums in this range is fitted with MGE motors which are asynchronous motors with built-in frequency converter. These motors are IE-comliant as standard.

4 ydro Multi-E Introduction Benefits Plug-and-um solution The ydro Multi-E is sulied as a comlete reassembled system mounted on a base frame. The only task left is to connect the ies and the ower suly. User-friendliness The ydro Multi-E is a highly intelligent booster system which is caable of controlling two to four seed-controlled ums in cascade. The ydro Multi-E is one of our most simle booster systems to start u and oerate. It has only two buttons for comlete control of the system. Alternatively, you can use Grundfos GO Remote for setu and control. Perfect constant-ressure control The seed-controlled ums are erfectly controlled and adjusted by the PI controller of the ydro Multi-E to deliver the correct ressure at the required flow. Reliability The Grundfos CRE, CRIE and CME ums are known for their reliability and long life. The PI controller is rotected inside the um and this has roven to be a very reliable solution. Multi-master function (0.7 to. kw) All ums that have a discharge-ressure sensor connected are caable of taking control of the entire booster system. This means that the system will continue to oerate as a booster system even if one or more of the ums or sensors are unavailable. Comared to systems with only one sensor, this makes the ydro Multi-E an extremely reliable solution. Redundant sensor (0.7 to. kw) No system is more reliable than the weakest comonent. In connection with booster systems, it is common to rely on only one ressure measurement. owever, that makes the oeration extremely deendent on one single sensor. On the ydro Multi-E, we do not deend on one sensor (single oint of failure) as the booster system is sulied with two discharge-ressure sensors as standard. Tested and ready to use Before delivery, all ydro Multi-E systems are carefully tested to Grundfos standard, i.e. ressure-tested and tested for full functionality. Low energy consumtion The ydro Multi-E ensures low energy consumtion through seed-controlled ums, automatic cascade control of the ums and highly efficient low-flow oeration. The highly efficient motors and ums also contribute to the overall high efficiency of the ydro Multi-E system.

Installation Mechanical installation A ydro Multi-E booster system must be installed in a well-ventilated room to ensure sufficient cooling of the ums. ydro Multi-E is not suitable for outdoor installation. Place the booster system in such a way that there is sufficient clearance around it for the oerator to be able to work freely. Enclosure class: IP5. Insulation class: F. Motor cooling To ensure adequate cooling of motor and electronics, the following must be observed: Place the ydro Multi-E in a well-ventilated room. The temerature of the cooling air must not exceed C. Motor cooling fins, holes in fan cover and fan blades must be ket clean. Electrical installation The electrical connection and rotection should be carried out in accordance with local regulations. The ydro Multi-E must be correctly earthed. Note:.0 to 5.5 kw motors must be connected to esecially reliable/sturdy earth connections due to an earth leakage current above.5 ma. The ums require no external motor rotection. The motors incororate thermal rotection against slow overloading and blocking (IEC -: TP ). When the ums are switched on via the ower suly, they will start after arox. 5 seconds. Note: The number of starts and stos via the ower suly must not exceed four times er hour. If the system is sulied with a breaker box for wall mounting, the cabinet must be mounted in accordance with local regulations. Installation Piework The ies connected to the booster system must be of adequate size. Fit exansion joints in the suction and discharge manifolds to avoid resonance. The ies are to be connected to the suction and discharge manifolds. The booster system should be tightened u rior to startu. We recommend to fit ie suorts both on the suction and the discharge side. The booster system should be ositioned on an even and solid surface, for examle a concrete floor or foundation. If the booster system is not fitted with vibration damers, it must be bolted to the floor or foundation. TM Fig. 8 Piework Pos.

14 5 ydro Multi-E Control of ydro Multi-E Building management system (BMS) Communication with the ydro Multi-E is ossible even though the oerator is not resent near the ydro Multi-E. Communication is enabled by having connected the ydro Multi-E to a building management system allowing the oerator to monitor and change control modes and setoint settings of the ydro Multi-E. The communication interface between the ydro Multi-E system and a central building management system varies, deending on um size. ydro Multi-E, 0.7 to. kw These booster systems can communicate with external systems via a Grundfos communication interface module (CIM) that can be fitted in the ums. This means that no external communication interface is required. ydro Multi-E,.0 to 7.5 kw These booster systems can communicate with external systems via an external Grundfos communication interface unit (CIU). Control modes Constant-ressure mode ydro Multi-E is suitable for alications where you want to control the ressure on the discharge side of the booster system, irresective of the flow. Signals of ressure changes in the iing system are transmitted continuously from the sensor to the ydro Multi-E. The um resonds to the signals by adjusting its erformance u or down to comensate for the ressure difference between the actual and the desired ressures. As this adjustment is a continuous rocess, a constant ressure is maintained in the iing system. In constant-ressure mode, the ydro Multi-E maintains a reset ressure on the discharge side of the booster system, irresective of the flow. Fig. Constant-ressure mode set set Q TM To meet the flow requirements of the system, the ydro Multi-E continuously adjusts the number of running ums.

16 6 ydro Multi-E Functions Descrition of functions Automatic cascade control Cascade control ensures that the erformance of the ydro Multi-E is automatically adated to the consumtion by switching ums on or off. The system thus runs as energy-efficiently as ossible with a constant ressure and only the number of ums required. Dry-running rotection This function is very imortant as dry running may damage bearings and shaft seals. The inlet ressure of the system or the water level in a ossible tank on the inlet side is monitored. If the inlet ressure or the water level becomes too low, all ums will be stoed. Level switches, ressure switches or analog sensors signalling water shortage at a set level can be used. Note: Analog sensors are only available for 0.7 to. kw systems. Pum alternation This function ensures that the oerating hours are distributed evenly on the ums over time. Number of starts er hour This function limits the number of um starts and stos er hour. Each time a um starts or stos, the system will calculate when the next um is allowed to start or sto in order not to exceed the ermissible number of starts er hour. This function always allows ums to be started to meet the requirement, but um stos will be delayed, if necessary, in order not to exceed the ermissible number of starts/stos er hour. Sto function The sto function checks the flow regularly by reducing the seed for a short time, thus checking the change in ressure. If there is no or a small change in ressure, the um will detect a low flow. When the um detects a low flow, the seed will be increased until the sto ressure (actual setoint x Δ) is reached and the um stos. When the ressure has fallen to the start ressure (actual setoint x Δ), the um will restart. Δ indicates the difference between start and sto ressures. Limit exceeded and ydro Multi-E, 0.7 to. kw The limit-exceeded function is used for monitoring one or two values/inuts. The function enables different inuts to activate various oututs and alarms/warnings when the signal inut has exceeded redetermined limits. The urose of this function is to monitor arameters which are central for the alication. This will enable the ums to react to ossible abnormal oerating conditions. The function can for instance be used for monitoring the following: the inlet ressure if an inlet ressure sensor is connected the drinking water temerature if a temerature sensor is connected. Multi-master function ydro Multi-E, 0.7 to. kw All ums that have a discharge-ressure sensor connected can function as master um and control the system. As standard, the ydro Multi-E is sulied with two discharge-ressure sensors. As standard, the um with the lowest number will be the master um. From factory, the master um is marked with number. If the master um is switched off or stoed due to an alarm, one of the other ums will automatically take over the control of the system. Thereby, the reliability is increased and sto of oeration is revented. As an otion, the system can be sulied with only one discharge-ressure sensor. In that case, the system will sto if the um or sensor fails. The system can also be fitted with sensors on all ums for maximum reliability. Sto ressure Δ Start ressure Fig. 5 Start and sto ressures Δ is factory-set to 0 % of actual setoint. Δ can be set within the range from 5 to 0 % of actual setoint. The ydro Multi-E is fitted with a diahragm tank of an aroriate size to accommodate the oeration in low flow. The recharge ressure must be 0.7 x actual setoint. TM

17 ydro Multi-E 6 Pie-filling function ydro Multi-E, 0.7 to. kw This function ensures a soft start of systems with emty iework. The function has two hases:. The iework is slowly filled with water.. When the ressure sensor of the system detects that the iework has been filled with water, the ressure is increased until it reaches the setoint. See fig. 6.. Filling hase. Pressure build-u hase Filling time Fig. 6 Filling and ressure build-u hases The function can be used to revent water hammer in high-rise buildings with unstable ower suly or in irrigation systems. External setoint influence ydro Multi-E, 0.7 to. kw This function is used for influencing the setoint via an external setoint signal. The value of the external setoint signal is used in a formula calculating a "new" setoint, i.e the actual setoint. The function is often used for adjusting the setoint deending on an external inut from a Grundfos VSF flowmeter. Predefined setoint Ram time Time [sec] ydro Multi-E, 0.7 to. kw This function is used for changing between redefined setoints via digital inut signals. This means that the oerator can easily change setoint by ressing a button. Due to the combination of digital inuts, u to three redefined setoints can be configured.

42 9 ydro Multi-E Otional equiment 9. Otional equiment All otional equiment, if required, must be secified when ordering the ydro Multi-E booster system, as it must be fitted from factory rior to delivery. Dry-running rotection ydro Multi-E, 0.7 to. kw As standard, the ydro Multi-E is fitted with a ressure switch as dry-running rotection. The switch is fitted to the suction manifold. Otionally, the system can be sulied with a level switch instead of the ressure switch. This is common if the booster system is sulied from a break tank. As an alternative, the system can be factory-fitted with inlet-ressure sensors for dry-running rotection. The benefit of this otion is that it is easier to adjust the trigger level of a sensor and that the inlet ressure can be monitored with Grundfos GO Remote and via a connected BMS system (CIM module required). To ensure that the system is roerly rotected against dry running, an inlet-ressure sensor must be connected to the ums that can otentially act as master. This means that every um that has a discharge-ressure sensor connected should also have an inlet-ressure sensor connected. The sensors are available from 0 to bar and from 0 to 6 bar. Note: If a sensor is used for dry-running rotection, it requires a Grundfos GO Remote to adjust the trigger level of the sensor. If the system is fitted with two discharge-ressure sensors (standard), the two inlet-ressure sensors are fitted in the suction manifold with a drain valve and a T-iece. The drain valve allows for test of the dry-running function. If the system is configured with more than two discharge-ressure sensors, a secial connecting iece with a built-in air vent is used. The connecting iece is fitted to a drain valve. Fig. Installation of more than two sensors Note: The standard ressure switch normally sulied with the system is removed when the system is fitted with inlet-ressure sensors for dry-running rotection. Emergency oeration ydro Multi-E,.0 to 7.5 kw The emergency oeration feature ensures the suly of water in these cases: sensor fault controller fault (um ). If emergency oeration is required, this must be stated when ordering. Then two or three ressure switches will be fitted to the discharge manifold rior to delivery.

43 ydro Multi-E 9 Non-return valve on suction side For suction-lift oeration, the non-return valve can be moved to the suction side. This is often used in combination with a foot valve if the system is drawing water from a tank. No dry-running rotection The ydro Multi-E can be sulied without dry-running rotection. Note: We always recommend you to rotect your system against dry running. Discharge-ressure sensor on each um ydro Multi-E, 0.7 to. kw As standard, the ydro Multi-E is fitted with two discharge-ressure sensors. If required, the system can be fitted with a sensor on each um. The benefit is that all ums in the system can act as master um and control the system. When more than two discharge-ressure sensors are connected, the sensors are fitted in a secial connecting iece with a built-in air vent in the to. The connecting iece is fitted to a drain valve. No redundant sensor The system can be sulied with only one discharge-ressure sensor. Note: This disables the multi-master function. Wall-mounted breaker box A breaker box for wall-mounting and five metres of flexible cable are sulied with the booster system. With this otion the breaker box does not necessarily have to be installed in the same room as the booster system. The ums are wired with five metres of cable, but not wired into the breaker box. The reason for not connecting the cables in the breaker box is to give the customer the oortunity to adjust the cable length to his need. CIM communication interface modules ydro Multi-E, 0.7 to. kw Fig. Grundfos CIM communication interface module The CIM modules enable communication of oerating data, such as measured values and setoints, between the ydro Multi-E and a building management system. Note: CIM modules must be fitted by authorised ersonnel. The CIM module enables transfer of data such as: oerating mode setoint control mode warnings and alarms ower/energy consumtion. We offer the following CIM modules: Module CIM 0 CIM 0 CIM CIM 00 CIM CIM 70 CIM 00 CIM 0 Aerials for CIM Descrition Aerial for roof Aerial for desk Fieldbus rotocol GENIbus LonWorks PROFIBUS DP Modbus RTU GSM Grundfos Remote Management BACnet MS/TP PROFIBUS I/O / Modbus TCP GrA6 Otional equiment Left-side breaker box As standard, the breaker box is mounted on the right side of the system. As an alternative, the system can be sulied with the breaker box mounted on the left side.
