Position Qty. Description 1 Control MPC-S 2x37 SD Product No.: 961876 Note! Product picture may differ from actual product Product description Control MPC-S is a multi-pump controller designed for control and monitoring of up to six identical Grundfos mains-operated pumps. Control MPC-S is used for control of pumps in booster systems or circulation systems for heating, cooling and air-conditioning. Control MPC-S ensures optimum adaptation of the performance to the demand by closed-loop control of these parameters: - pressure - differential pressure - flow rate - temperature - differential temperature. Control MPC-S can also control pumps running in open-loop control. Control MPC-S incorporates a control cabinet with a CU 351 multi-pump controller, IO 351 A/B module(s), a main switch and all the necessary components and wiring. The control cabinet is designed for floor-mounting. At the first start-up, Control MPC-S will show a start-up wizard which helps you commission your system according to your specific installation. When the start-up wizard is completed, the Control MPC-S will operate according to your special requirements. Functions Control MPC-S incorporates the setting/monitoring of the following functions: - Setpoint - Warnings and alarms - Alarm log (storage of up to 24 warnings and alarms) - PI controller adjustment - Alternative setpoints (setting of up to six alternative setpoints) - External setpoint influence (letting measured parameters influence the setpoint) - Primary sensor setup (selection of the control parameter of the system) - Clock program (setting of setpoints and time and day for their activation) 3/13
Position Qty. Description - Proportional pressure (setting of proportional pressure operation) - S-system configuration (normal or inverse control of mains-operated pumps) - Min. time between start/stop of pumps (setting a delay between the starting/stopping of one pump) - Max. number of starts/hour (limitation of the number of starts/stops per hour) - Standby pump allocation (selection of one or more pumps as standby pumps) - Forced pump changeover (setting of pump changeover so that pumps run for the same number of operating hours) - Pump test run (prevents pumps from seizing up and liquid from decaying in pumps, and removes trapped air) - Pilot pump (control of pilot-pump operation in low-flow situations) - option - Pump stop attempt (automatic stop attempts, self-learning or at fixed intervals) - Pump start and stop speeds (control of start and stop speeds of pumps) - Compensation for pump start-up time (compensation for the time it take a mains-operated pump to reach full performance) - Stop function (stop of the last pump in operation during low-flow situations) - Soft pressure build-up (ensures smooth start-up of systems with empty pipes) - Emergency run (pumps keep running regardless of warnings and alarms) - Setting of digital inputs - Setting of analog inputs - Setting of digital outputs - Pump curve data (entering of data describing the performance curves) - Control source (control from CU 351 or via bus connection) - Fixed inlet pressure (setting of fixed inlet pressure) - Flow estimation (optimisation of operation according to performance curves) - Dry-running protection (with pressure/level switch, pressure transmitter or level transmitter) - Min. pressure (monitoring of minimum pressure) - Max. pressure (monitoring of maximum pressure) - External fault (monitoring of external fault) - Limit exceeded 1 and 2 (monitoring of a set limit 1 (warning limit) and limit 2 (alarm limit) - Pumps outside duty range (indication of whether pumps fall outside duty range) - Pressure relief function (monitoring of maximum system pressure) - option - Display language (selection of display language) - Display units (SI or US units) - Date and time (setting of day and time) - Passwords (setting of password for menu?operation? and/or?settings?) - Ethernet connection (controlling the system from a remote PC) - GENIbus number (allocation of GENIbus number) - Software status (status of software version). Control MPC was designed according to these directives: - Machinery Directive (98/37/EC) Standards used: EN 89 [2] and EN 624-1 [26]. - EMC Directive (24/18/EC) Electrical data: Power (P2) main pump: 37 kw Mains frequency: 5 Hz Rated voltage: 3 x 38-415 V, 5-6 Hz, PE Rated voltage main pump: 3 x 38-415 V Starting main: SD Rated current of system: 144 A Current range main pump: 64.1.. 72 A Enclosure class (IEC 34-5): IP54 Mains cable size: 4x7-95 mm2 Radio interference supression: EMC Certificate - Control MPC 1 [27] 4/13
