machine��
Lead/Lag –
When this box is checked the compressor is
operating as a lead machine�� Unchecking the box causes
the machine to run as a lag machine��
Lag Offset –
If the machine is running as a lag
compressor, the lag offset will be subtracted from the
online and offline setpoints��
Range (in PSI): 0 – 45, depending on the online and offline
setpoints�� The Lag Offset will never allow you to exceed
the minimum or maximum values of the online and
offline setpoints��
Mode of Operation – Selections are Online/Offline,
Modulation/ACS, and Modulation only – determines how
the compressor will try to maintain a specific pressure��
Online/Offline – The compressor will load the
machine by energizing a solenoid that opens the inlet
valve and closes the blowdown valve when package
discharge pressure falls below the online pressure
setpoint�� The compressor will unload the machine by
de-energizing the solenoid when pressure rises above
the offline pressure setpoint��
Modulation –
The compressor will still load and
unload as in online/offline, but will energize a different
solenoid valve for modulation�� When the package
discharge pressure is between the online and offline
setpoints the compressor will adjust the inlet valve in
order to achieve a stable output pressure�� The output
pressure target needs to be set by a technician at the
inlet valve in order to provide effective modulation
control�� Modulation can only work when the package
discharge pressure is above 60 psi�� Modulation is an
option and must be enabled in the factory settings tab��
Mod/ACS –
The compressor will initially start out in
online offline mode�� If the compressor goes through 3
load/unload cycles within 3 minutes, it will switch over
into Modulation mode�� It will remain in modulation
until the stop button is pressed or 3 minutes pass
between an unload and load command�� Mod/ACS is an
option and must be enabled in the factory settings tab��
Unloaded Stop Time – Time period that the machine
must run unloaded before the motor is allowed to stop
after a stop command is received��
Range (in seconds): 10 - 30
Starter Time – Time period that the compressor needs
in order to come up to operating speed after a start
command before being able to produce air�� Range (in
seconds): 5 - 30
The parameters on these pages are adjustable any time��
*Note that Mode of Operation can only be adjusted
if the modulation option has been purchased for the
compressor and the Enable Modulation factory setpoint
has been turned ON��

Enable Auto-Restart –
Enabling this will allow the
compressor to stop if it has been running unloaded for a
period of time, and the motor has exceeded its minimum
running time (10 minute in most cases)��
Auto-Restart Time –
The time period the compressor
must run unloaded before stopping in auto-restart�� This
time period begins the moment that package discharge
pressure rises above the offline setpoint�� Both this time
period and the minimum motor run timer (10 minutes)
must be satisfied before the compressor will stop in auto
restart��
Range (in seconds) 2 - 60
