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.
