Envelope Protect: When set to “Yes” (default) the compressor envelope
protection alarm is enabled. The envelope logic will change the compressor’s
speed to bring it into the normal operating zone. However, if compressor continues
to run outside the envelope, the compressor will shut down for its Minimum Off
Time. Notice: since the envelope function protects the compressor, it should not be
disabled unless directed by a factory technician.
Start-Up Delay: This delay blocks the out of envelope alarm when the compressor
starts. Range of adjustment is 15-180 seconds with a default setting of 100
seconds.
Run Outside Delay: This delay bocks the out of envelope alarm when the
compressor leaves from an operational zone. Range of adjustment is 0-99
seconds with a default setting of 1 second.
Max Number Alarms: The maximum number of envelope alarms that can occur in
1 to 7 days before the compressor will be locked out and require a manual reset.
Range of adjustment is 1 to 10 times with a default setting of 3. The time interval
has a range for selection of 1 to 7 days with a default of 1 day.
Log Abnormal Zones: Records when compressor operates within abnormal
zones (2-5) in the alarm log. Default selection is No.
