Section IV - Operating Procedures
MENU:
Press this button to access the setup
menus for the compressor. There are
8 menus in this section. These
include the service intervals, sensor
calibration etc. Press MENU, then
p
or
q
to scroll through the menus. To change
the values on any of these menus, press
ENTER, then
p
or
q
to set the value, then
ENTER again.
There are three operating modes available:
auto-dual, continuous run and network
mode. Select zero (0) for auto-dual mode,
one () for continuous run mode, or two (2)
for network mode.
Service hours are preset to default values
but can be changed here, if desired.
These are count down timers and are used
as service reminders. A message will be
displayed on the main running menu when
any of these timers reaches zero.
The pressure transducer range is 0 to 300
psi. To calibrate the pressure transducer,
disconnect the pressure line to the sensor,
and vent to atmosphere to zero (the
number on the screen has no effect on the
calibration; it is just a dummy value. Press
ENTER to set the zero).
The standard temperature scale is 0 to
300°F.
To calibrate the temperature, press ENTER,
then
p
or
q
to match the temperature at
the probe.
Shutdown temperature is a preset value.
During start-up, the compressor will
automatically raise this setting to 250° for 2
minutes to handle overshoots.
The shutdown temperature can be altered
at this menu, however, this should only be
done as a last resort.
The Y/D time is the time (in seconds) that
the motor remains in reduced voltage start
mode before transitioning to run mode.
Too large a value can cause the motor to
bog-down on start. A correct value, will
give a fairly smooth transition to run mode.
Each compressor in the network must have
a compressor ID (a unique letter of ‘A’ to
‘F’) to run in network mode.
The HP setting, along with other
compressor data, is transmitted to other
compressors on the network.
