Section IV - Operating Procedures
S.S. RAMP time is for Solid State / Soft
Starts to match the ‘up to speed’ intervals.
The Y/D delay sets the transition time for
reduced voltage starts.
The Capacity display requires the addition
of a vacuum sensor and analog module to
add a capacity gauge on the main running
screen. The display will approximate the
load conditions for the compressor, based
on the inlet conditions. NOTE: the reading
is only approximate, as it is also affected
by the fi lter conditions. See Appendix A for
installation.
The D.P. Switch is an option for those
compressors that have a fi lter monitoring
switch. Those switches monitor the fl uid
fi lter and separator condition, and will
provide an indication of blockage when
tripped.
This is where information specifi c to the
compressor’s physical parameters is setup.
Select the 3 starter types (ACL, Y/D and
Solid state) by pressing the bar to rotate
the selection.
CONFIG:
This menu is to restore runtime hours to a
compressor that had it’s PLC replaced.
SETUP HOURS: (Sub Menu of CONFIG).
