RS.8D.M1.22 AK2-SC 255 Reference Manual 23
Stop comps on high temp (List box: Yes, No) Whether or not compressors are to
be shut down on high discharge temperature.
Cutout (0.0 to 300.0) The discharge temperature at which
compressors are to be cut out.
Cutin (0.0 to 300.0) After a cut-out on high discharge
temperature, the discharge temperature at which
compressors are to be cut in.
Stop comps on low temp (List box: Yes, No) Whether or not comrpessors are to
be cut out on low discharge temperature.
Lockout (0 to 255) The number of minutes that must elapse
before a lockout on low discharge temperature. (See
note on next field).
below (0 to 300) The temperature that discharge must be
below for the time specified in the preceding field
before lockout on low discharge temperature occurs.
Note: If discharge temperature rises above the
setpoint, the time for lockout will restart from zero.
Disch pressure safety (List box: Yes, No) Whether or not comrpessors are to
be cut out on high discharge pressure.
Cutout (0.0 to 500.0) The discharge pressure at which com-
pressors are to be cut out.
Cutin (0.0 to 500.0) After a cut-out on high discharge
pressure, the discharge pressure at which compressors
are to be cut in.
Unload before cutout (List box: Yes, No) Whether or not comrpessors are to
be unloaded before being cut out.
Neutral Zone
control The next page of compressor configuration deals with neutral zone control. Basically,
neutral zone control acts to bring the current pressure toward target pressure more
quickly the greater the difference between the two. The screen looks like this:
The default settings are as shown in the screen above. It is recommended that the
values not be changed without a thorough understanding of the algorithm. A thorough
explanation of neutral zone control is available as an appendix to this manual.
