the factory; however, they should be
checked during start-up and adjusted,
if necessary. Some applications may
require a slightly different setting than
those provided by the factory. Refer
to the Service Adjustment Section VIII.
Never increase air pressure settings
beyond factory specifications.
•
Water-cooled units -

water temperature regulating valve
to maintain 80°F discharge air

Control Panel Operation
Drive Status
The ‘Drive Status’ informational screen is
accessed from the Start-up Screen (figure
4-) and is not a password protected
screen. This screen shows the current
operating conditions on the motor
including supplied voltage(s), current
draw, computed torque and resultant
horsepower.
The Max CFM and Min CFM are taken from
the model data sheets and show the rated
delivery at 0 psig.
notiCe!
Other pressure settings will alter these
numbers and will not be shown here.
The %CAP is a rough indication of the
current delivery of the compressor. This
value is taken from the speed of the motor.
Touch ‘View Events’ to display a list of the
last eight logged drive events.
Each logged drive event is listed with an
associated date stamp. The date stamp is
stored in the drive as the internal time in
days and hours from the drive setup time.
The most recent event will be at the top of
the list.
