Xcm25D Electronic Controller - Programming; Programming The Local Display; Figure 9: Local Display - Emerson Copeland EazyCool ZXDI Series Application Manuallines

The unit will be turned on for the minimum run time when the low-pressure input is closed.
If the pressure drops below the cut-out value or the low-pressure input opens, the unit should
continue to run for the remaining minimum on time (C14/LAS) or until a satisfactory condenser
pressure is reached (C13/LAd).
If a suction pressure transducer is present and the suction pressure falls below a given value
(C15/LAT) during the minimum on time (C14/LAS), then disregard the timer and shut the
compressor off to protect against vacuum operation.
NOTE: For additional features please contact your local Application Engineering
representative.

CAUTION
Low refrigerant charge! Compressor damage! Never energize the

malfunction of the controller in deep vacuum operation which can cause
compressor damage.
