Paging down, you will find a page for each compressor in the suction group. These
subsequent screens will have only questions pertaining to the individual compressors,
not the rack questions found at the top of the screen for compressor number one.
After basic operating data has been entered for all compressors, paging down will
produce this screen:
The fields and their contents are as follows:

(List box: Yes, No) Whether or not oil control is
implemented.
(List box:)
Sensor Input: An analog input (sensor input) is used
to monitor oil pressure.
On/Off: A digital input (on-off input) is used to monitor
an oil pressure switch.
Copeland: A Copeland oil monitor is used.
(List box: Yes, No) Whether or not compressors will
be locked out when an oil failure is detected.
(0 to 50) The oil pressure differential, when an analog
sensor input is used, that will cause compressor
shutdown.
(0 to 255) When an analog sensor is used, the number
of seconds after oil failure is detected before compres-
sors are reset.
(0 to 10) After oil failure is detected, the number of
reset attempts before compressors are locked out.
(0 to 60) After a reset (whether successful or not) the
number of minutes that must elapse before another
reset attempt.
discharge temperature is monitored.
