923456781The Emotron DCM is a control unit that remotely controlssubmersible pump equipment. Level sensors are not neededto initiate start and stop. The pump stops automaticallywhen it begins to snore (draw air), when the pit has beenpumped free from water. During a pumping operation, theEmotron DCM measures the length of the run period anduses this to determine the length of the rest period. Thelonger the run period, the shorter the rest period. As a resultthe run and the rest periods are continuously adapted to therate of flow.Two Emotron DCMs can be connected in parallel to controltwo submersible pumps and allow independent operationand display of monitored values. The “dual-pump DCMsystem” must not be installed in a pit of extremely smalldiameter or width. This will result from time to time in theDCMs failing to detect the stop/minimum level.*)Terminal covers optional.Fig. 1Emotron DCM and current transformer (CT), both for mounting on standard DIN rail 35mm.L1L2L3NExceeding 100 AmpsNumber of primary and secondary windings see Table 2L1CTM 010Max. 10 ASS StandardtransformerAutosetMax 240VACAUpto 100 AmpResetAlarmNumber of primary windings see Table 1L1High levelStopK1K1CTM xxxF1Alternativ anslutningS1 S2 Dig SGND Temp Allarm C PumpDCML1L2L31113F1UVWThermistor PTC-+MASelection, see Manual:Digital Input connectionDig and SGND, term. 3 and 4.ThermocontactFig. 2Connection exampleNOTE: Make sure that the DCM voltage range e.g. 3x380-500 VAC matches the connected pump motor/line voltage, e.g.3x 400 V.1 CG Drives & Automation 01-5964-01r0
