SeeFig. 5. In addition, a 24-v time delay relay and contactor is usedto deenergize the entire control power of the chiller as part ofthe protection scheme. See Fig. 6. The reverse rotation boardhas two LEDs (light-emitting diodes) and two adjustable dialsettings. Under normal conditions, the upper LED will light upgreen. The lower LED is red and will flash (phase reversal) orturn on solid (phase loss and under-voltage) according to theconditions sensed.DIAL SETTINGS — The reverse rotation board has two dials.See Fig. 5. The upper dial should be set to match the incomingthree-phase voltage to the chiller with no compressorsrunning. This dial must be adjusted for 208/230-v chillers operatingon 208-v power supply. The dial should be adjusted to200-v minimum setting for this case. The lower dial is used fortrip delay and should be set fully counterclockwise to the minimum0.1 second setting. The time delay relay in the 24-v circuithas a delay setting as well and it should be set fully clockwiseto the maximum 1.0 second setting. See Fig. 6.PHASE REVERSAL PROTECTION — The control monitorsthe three-phase power sequence supplied at terminals L1,L2, and L3. If the control senses an incorrect phase relationship,the relay contacts (11/14) on the board will open. The relaycontacts will automatically reset when the correct phase sequenceis applied.PHASE LOSS AND UNDER-VOLTAGE PROTEC-TION — If the reverse rotation board senses that any one ofthe three phase inputs has no AC voltage or that any one phasehas dropped more than 20% below the voltage dial setting, therelay contacts (11/14) on the board will open. In addition,board relay contacts (21/24) will also open. If the contacts donot close within one second (time delay relay dial setting), the24-v control power to the chiller will be removed and all motoroutputs will be turned off. Control power will be restored automaticallywhen all three phases are present, in the correct sequenceand are within the limits of the voltage dial setting.LED STATUS<strong>Up</strong>per (green) LED on continuouslyLower (red) LED blinkingLower (red) LED on continuously<strong>Up</strong>per (green) LED offFUNCTIONRelay contacts closed (normaloperation)Relay contacts open (phase reversalhas occurred)Relay contacts open (phase lossor under-voltage has occurred)Power not present at L1, L2, L3(off)NOTE: Normal operation of the reverse rotation board (forexample, no faults are detected) results in a closed contactbeing applied to the MBB (plug J5A, channel 16B) through theclosed 11/14 relay contact.11
