9For a complete description of Main Base Board inputs and out-puts and their channel identifications, see Table 3.Compressor Protection Module (CPM) — Thereis one CPM per compressor. See Fig. 9. The device controls thecompressor contactors, oil solenoid, loading/unloading thesolenoid, motor cooling solenoid (30XA080,082 only) and theoil separator heater. The CPM also monitors the compressormotor temperature, high pressure switch, oil level switch, dis-charge gas temperature, oil pressure transducer, motor current,MTA (must trip amps) setting and economizer pressure trans-ducer. The CPM responds to commands from the MBB (MainBase Board) and sends the MBB the results of the channels itmonitors via the LEN (Local Equipment Network). The CPMhas three DIP switch input banks, Switch 1 (S1), Switch 2 (S2),and Switch 3 (S3). The CPM board DIP switch (S1) configuresthe board for the type of starter, the location and type of thecurrent transformers and contactor failure instructions. See Ta-ble 4 for description of DIP switch 1 (S1) inputs. See AppendixD for DIP switch settings.The CPM board DIP switch S2 setting determines the musttrip amps (MTA) setting. See Appendix D for DIP switch set-tings. The MTA setting which is calculated using the settingsS2 must match the MTA setting in the software or an MTAalarm will be generated.See below for CPM board DIP switch S3 address informa-tion. See Table 5 for CPM inputs and outputs.NOTE: The CPM-A and CPM-B DIP switches are for allunits. The CPM-C DIP switches are for 30XA400-500 units.Electronic Expansion Valve (EXV) Board —The 30XA080,082 unit has one EXV board. The 30XA090-500 units have one EXV board per circuit. See Fig. 10. Theboard is responsible for monitoring the suction gas temperatureand economizer gas temperature thermistors. The board alsosignals the main EXV and economizer EXV (ECEXV) motorsto open or close. The electronic expansion valve boardresponds to commands from the MBB and sends the MBB theresults of the channels it monitors via the LEN (Local Equip-ment Network). See below for DIP switch information. SeeTables 6 and 7 for EXV inputs and outputs.CPM-A DIP Switch 1 2 3 4Address: OFF OFF OFF OFFCPM-B DIP Switch 1 2 3 4Address: OFF OFF ON OFFCPM-C DIP Switch 1 2 3 4Address: OFF OFF OFF ONEXV BOARD A(080-500)DIP SWITCH1 2 3 4 5 6 7 8Address: ON ON ON ON ON ON OFF ONEXV BOARD B(090-500)DIP SWITCH1 2 3 4 5 6 7 8Address: OFF ON ON ON ON ON OFF ONEXV BOARD C(400-500)DIP SWITCH1 2 3 4 5 6 7 8Address: ON OFF ON ON ON ON OFF ON221221 221221195195195195195195195CH1 CH2 CH3 CH4CH11 CH12LOCATION OFSERIAL NUMBERCH13 CH14 CH15AJ4ANALOGINPUTSJ3J2CJ2B24 VACJ1A+ G –DISCRETEINPUTSJ5ACH15a11 C16J2ATR1 TR2 TR3 TR4 TR5CH19 CH20 CH21 CH22 CH23 CH24 CH25 CH26J8CH17 CH18J5B J5CTHERMISERS PRESSURESCH5 CH6 CH7 CH8 CH9J7A J7B J7C J7DRELAYOUTPUTSMOV1C41 C42 C43C32 C33 C34 C3512/11 12/11J10LEN+ G -STATUSJ9AK1 K2D15J6CCNCH10+ G –SIO(LEN)J9C J9B+ G –LEN LENCCN J13 J9D+C+CCH16a+CCH16bFig. 8 — Main Base Boarda30-4255
