3.3 USER ADJUSTABLE CONTROL PARAMETERS
Listed below are descriptions of the parameter that can be adjusted at the WS Controller:
Unload Pressure
- Set point (psi, bar, or kpa) at which the system pressure will begin
unloading. For example if this parameter is set to 110 psi (7.6 bar) the machine will
unload when the line pressure is above 110 psi (7.6 bar).
Load Delta Pressure
- The pressure differential (psi, bar, or kpa) below the unload
pressure at which the machine will begin loading. For example if the unload pressure
is set to 110 psi (7.6 bar) and the load differential is set to 10 psid (0.7 bar), the
machine will load when the line pressure goes below 100 psi (6.9 bar).
VSD Setpoint Pressure
- (VSD packages only) The targeted pressure (psi, bar, or
kpa) for the variable speed controls. This is normally adjusted near the bottom of the
load/unload band above. The speed will be adjusted to maintain this pressure. Refer
to Section 7 for additional details.
Unload Minutes
- Set time that the machine will run unloaded in Auto mode before
shutting off. If the time is set less than 15 minutes (for example 5), there may be times
when the machine will run unloaded for more than 15 minutes. This is because there is
another timer that keeps the machine from being started more than four times an hour.
This secondary timer is disabled when a machine is configured for VSD motor control.
Drain Interval Mins.
- Set interval in minutes between activation of the drain cycle for
machines equipped with an electric solenoid drain. This does not apply to the Sullair
SCD zero loss drain, which is not controlled or monitored by the WS Controller.
Drain Time Seconds
- Set time in seconds that the drain remains energized.
Wye Delta Seconds
- Set time for wye to delta starter transition. Also used to control
the closed inlet start valve. Disable by setting to zero (0), standard for full voltage start.
Requires approximately 4-6 seconds for wye-delta or solid state starting.
Modulate -
Manner in which the machine is set to regulate compressor flow. Default
state is “YES” for proportional control. Select “NO” for Load/No Load operation.
Operating Mode
- The mode set for controlling the compressor motor operation
(Manual / Automatic).
Language
- The choice of language for text that will appear on the display screen
(English, French, Spanish, German, Italian, Chinese).
The Diagram of Figure 3.1 shows the flow of the screens that appear on the WS
Controller display screen. This diagram illustrates how adjustment parameters are
accessed.
If during the adjustment process, the START or STOP pad is
pressed prior to pressing the ENTER pad, the display will return to the
NORMAL view and the parameter value will not be changed.
