Stopped to Starting

The following diagram shows the timing from a
stopped mode to energizing the first compressor. The
shortest allowable time would be under the following
conditions:

•

No motor restart inhibit time left from subsequent
starts

•

Evaporator Water flow occurs quickly with pump on
command

•

Need to cool (differential to start) already exists

•

The above conditions would allow a compressor to
start in about 20 seconds.
