High Sump Pressure
Xe Software Logic for R & RS machines:
W: If the compressor is running loaded, has been
loaded for at least 8 seconds and the sump pressure is
more than 25 psi (1.72 Bar) above the rated pressure
for the compressor. If this warning occurs, the online
and offline pressures will be reduced (PAC logic ID
11439). This condition must exist for 3 seconds before
the warning is issued.
A: This will occur if the compressor is running loaded
for at least 8 seconds, and any one of the 3 following
conditions exist: (1) the sump pressure is above the
rated pressure by 35 psi (2.41 Bar). (2) The separator
pressure drop is measured to be more than 25 psi
(1.72 Bar) and the package discharge pressure at least
equal to the minimum online set point value. (3) The
sump pressure is above 165 psi (11.38 Bar) if the rated
pressure is less than 190 psi (13.1 Bar) or the sump
pressure is above 220 psi (15.17 Bar) if the rated
pressure is 190 psi (13.1 Bar).
