Table 29 — Cooling Configuration
If (rate after) is less than (rate prior minus 1.25), alarm
A140 is generated. This alarm will disable mechanical cooling
and will require a manual reset.
It is important to note that in Service Test mode reverse ro-
tation is checked on every compressor start.
Once it has been verified that power to the unit and com-
pressors has been applied correctly and the compressors start
up normally, this configuration can be set to YES to disable the
reverse rotation check.
