4.6 ELECTRICAL SYSTEM (Continued)

By use of an optional built-in Star-Delta type starter,
the compressor motor can be started and accelerated
using a greatly reduced “inrush” electric current. The
starter is completely automatic and controlled by the
Intellisys controller. Refer to the electrical schematic,
Section 8.0 schematic 8.2.

Options such as remote start/stop or power outage
restart with remote start/stop can be added by
installing a plug-in module in the controller.

4.7 CAPACITY CONTROL

The SE compressor is supplied with on-off line
control equipment.

Optional modulation control enables the compressor
to function with three operator selectable capacity
control systems, each designed for different plant air
requirements.

- Mod/ACS (modulation/automatic control sector)
- Modulation
- On-Off Line

The desired control is selected at the Intellisys
control panel (See Section 3.0).

Automatic Unloaded Start

The compressor will always start in the unload
mode. When unloaded, the inlet valve is nearly
closed, the blowdown solenoid valve is open (tank
vented), and the compressor is operating at
minimum power. The Intellisys will open the inlet
valve slightly to maintain the proper sump pressure
to insure positive oil flow and smooth, quiet
operation.

The minimum pressure check valve will prevent any
backflow of air from the plant air system during
unloaded operation.

On-Off Line Control

For those plants which have a widely varying air
demand, on-off line control will deliver air at full
capacity (compressor maximum efficiency condition)
or will operate at zero capacity (compressor minimum
power condition). The compressor is controlled by the
Intellisys, responding to changes in plant air pressure.
The Intellisys opens the inlet valve and closes the
blowdown valve (3SV) whenever plant air pressure
drops below the on-line pressure set point. The
compressor will then operate to deliver full capacity air
to the plant system. If the plant air system pressure
rises to the off-line set point of the Intellisys, the inlet
valve closes and the blowdown solenoid valve opens
the receiver vent line, allowing receiver pressure to
drop. The compressor will continue to run with
minimum power draw.

Automatic Start-Stop

Many plant air systems have widely varying air
demands or large air storage capacity which allows for
automatic standby air capacity control.

During periods of low air demand, if the line pressure
rises to the offline set point, the Intellisys begins to time
out. If the line pressure remains above the online set
point for as long as the set time, the compressor will
stop. At the same time the Automatic Restart light on
the display panel will be lit to indicate the compressor
has shut down automatically and will restart
automatically, and the display will show “AUTO
RESTART”. An automatic restart will occur when the
line pressure drops to the online set point.

The offline and online set points and shut down delay
time are set on the Intellisys control panel.
