The built in safeties shut down the unit and have alarms as follows:

1 beep every 3 sec. = High Evaporator Temperature >127 ° F.

Check for defrost problem (stuck HGV or relay), hot water entering unit, stuck headmaster, or shorted thermistor.

2 beeps every 3 sec. = Defrost Back Up Timer. Defrost >20 minutes. Orange LED marked 20 MIN energizes.

Check for open thermistor, HGV not opening, TXV leaking by, low charge, or inefficient com- pressor.

3 beeps every 3 sec. = Freeze Back Up Timer. Freeze > 60 minutes. Yellow LED marked 60 MIN energizes.

Check for F/S stuck closed (up), WV leaking by, HGV leaking by, TXV not feeding properly, low charge, or inefficient compressor.

To manually reset the above safeties, depress white alarm reset button with the power supply ON.

6 beeps every 3 sec. = Low Voltage. Voltage is 92 Vac or less.

7 beeps every 3 sec. = High Voltage. Control voltage > 147Vac ±5%. The red LED will de-energize if voltage protection operates.

The voltage safety automatically resets when voltage is corrected.

The Output Test switch “S3” provides a relay sequence test. With power OFF, place S3 ON and switch power to ICE. The correct lighting sequence should be none, 2, 3, 4, 1, & 4, normal sequence every 5 seconds. S3 should remain in the “OFF” position for normal operation.

The application switch located between relay X3 & X4 must be set to match the original board application. Place this switch in the ALP position if there is no white wire supplied to the K1 connector. If there is a white wire, place the switch in the C position. If this switch is placed in the wrong position either the compressor contactor will remain energized with the control switch OFF or the unit will not start.
