Section 6Electrical System6. HARVESTThe harvest valve(s) and HPRsolenoid valve remain open, allowingrefrigerant gas to warm theevaporator. This causes the cubes toslide, as a sheet, off the evaporatorand into the storage bin.The sliding sheet of cubes swings thewater curtain out, opening the binswitch. This momentary opening andclosing of the bin switch terminatesthe Harvest Cycle and returns the icemachine to the Freeze Cycle (steps3-4).TB35L1HIGH PRESCUTOUTTB32ICE THICKNESS PROBEWATER LEVEL PROBENOT USED(55)(62)24135TRANS.1CFUSE (7A)1F1G LOW D.C.VOLTAGEPLUG(20)(61)(60)(77)HARVEST (80)SOLENOID(76)(75)DUMP(81)(57)SOLENOIDTB31 (98)(99)WATERPUMP(58)TB37 (59) (83)(82)LIQUID LINESOLENOID(73) (74)CONTACTOR(56) COILCLEAN LIGHTWATER LEVELBIN SWITCH LIGHTSEE SERIAL PLATE FOR VOLTAGE(21)HPRSOLENOID(78)(22)WATERVALVE(79)L2 (N)TB30TB30TB30TB30(64)(66)(63)BIN SWITCH (65)(67)(66)(68) ICE(69)OFF(62) CLEANHARVEST LIGHT/SAFETY LIMIT CODE LIGHTTOGGLE SWITCH VIEW FOR WIRING68INTERNAL WORKINGVIEW66676269(49)TB35(42)CONTACTORCONTACTSL1TB33(51)(52)*OVERLOAD(48)RCTERMINATES ATPIN CONNECTIONCOMPRESSORS(53)(47)TB34RUN CAPACITORR R(46)(45)PTCR(50)TB30(F1)(F2)TB30REMOTEFAN MOTORRUN CAPACITORREMOTE CONDENSERSV1648-6Table 6-13.
