Eaton Cutler-Hammer LMR Instructions Manual

IM05805001K 1Effective November 2003INSTALLATION & MAINTENANCEMANUAL FOR LMR ELECTRICFIRE PUMP CONTROLLERSIn order to familiarize yourself with the LMR Electric Controllers, please read the instruction manual thoroughly and carefully.The parts of this manual that refer to the Run Period Timer (RPT) do not apply to the FDF - Foam Pump Controller. FDM -Medium Voltage controller information is available in section 16.0 of this manual. Additional medium voltage informationcan be found in Instruction Bulletin: I.B. 48022.1. Installation and Mountingof LMR ControllerCarefully unpack the controller and inspect thoroughly.The controller should be located as close as is practical tothe motor it controls and shall be within sight of the electricmotor, preferably ten feet or less.The LMR controller is designed for either wall or floormounting. Note that the controller is not free standing andmust be mounted with feet or bolted securely to a wall. Fordimensional and weight data please refer to the respectivedata sheets for the various types of Fire Pump Controllers.2. System Pressure ConnectionThe LMR is equipped with a Pressure Transducer. Thecontroller is provided with a ¼" NPT female systempressure connection located on the bottom, external sideof the enclosure. The connection should be installed asper NFPA, pamphlet No. 20.NOTE: Water lines to the pressure switch must be freefrom dirt and contamination.The actual pressure is displayed on the bottom left handcorner of the LCD Display. Precise start and stop pressureset points can be programmed into the controller. Refer toSection 6 for programming instructions. A print-out ofpressure readings is provided during alarm situations orpressure deviations.The pressure transducer and internal plumbing componentsare rated for a maximum of 600 PSI.3. Electrical ConnectionsNOTE: Do not drill or install incoming cables above thecontroller card.*OTHERWISE WARRANTY IS VOID*All electrical connections should meet national and localelectrical codes and standards.The controller should be located or so protected that theywill not be damaged by water escaping from pumps or pumpconnections. Current carrying parts of controllers shall be aminimum of 12 inches (305 mm) above the floor level.• Prior to starting, verify all data on the nameplate suchas, catalog number, AC line voltage, horsepower andfrequency. Also check all wiring connections andsystem pressure.• Inspect all electrical connections, components andwiring for any visible damage and correct as necessary.Ensure that all electrical connections are tightenedbefore energization.• Refer to the appropriate wiring schematic drawingincluded in this manual (page 15), and/or affixed tothe enclosure door, for all wiring information pertainingto the incoming AC power supply and motor wiring.• Install necessary conduit using proper methodsand tools.• Incoming AC line voltage is clearly marked L1, L2,L3 and ground, located at the top of the enclosure.3.1 Wire Sizes• For control wiring, use #14 AWG wire for allelectrical connections.• For power wiring sizes refer to TABLE 1, on page 16.3.2 Electrical Checkout InstructionsWARNING: The following procedures should be carriedout by a qualified electrician familiar with the electricalsafety procedures associated with this product and itsassociated equipment.3.2.1 To ensure the pump does not start upon energizingthe controller, make sure that the pressure at thetransducer (main controller sensing line) is 5 PSIor greater – or – hold the STOP button whileenergizing. The LMR’s START PRESSURE isfactory set at ‘0’ PSI. Once the controller isenergized the system pressure can be viewed onthe LCD display. Refer to Section 4.3. Placing ajumper between terminals 37 & 49 will lock thecontroller out ensuring that the pump will not startunexpected. After it is determined that the pump willnot start this jumper should be removed. (For FoamPump controllers, the controller can be started bymanual means as well.)3.2.2 Phase Sequence Check: The LMR controller isdesigned to be phase sensitive. L1, L2 & L3 shouldbe connected to A, B & C phases respectively.Energize the controller by closing the IsolationSwitch (MIS) and Circuit Breaker (CB). If the phasesare connected incorrectly, the “Phase Reversal”LED on the alarm display will be lit. To correct thiscondition, refer to Section 3.5 to correct the DP2switch setting. Re-energize the controller.
