following are detailed descriptions of the various
displays.
2.4 STATUS—CURRENT
PRESSURES,
TEMPERATURES, INPUTS
AND OUTPUTS
All inputs and outputs are displayed showing both the
designator and the description (eg. T1- Discharge)
along with the selected temperature (C or F) or
pressure (psi, bar, kPa) units. Digital inputs and
outputs are shown either as a ‘0’ (zero) or ‘1’ (one).
Zero is off and one is on. This is a view only display.
The order of display is :
Temperatures —T1 through T4 depending on model.
Pressures —P1 through P4 depending on model.
Delta pressures —dp1 through dp3 depending on
model.
Load Hours —Hours machine has run loaded.
Run Hours —Hours machine has run loaded or
unloaded.
Load Cycles— Number of load/unload cycles.
Starts —Number of times machine has started.
E-Stop String —E-Stop push button.
Aux E-Stop —Auxiliary E-Stop, wired by customer.
Digital Inputs —D1 through D10, depending on
model.
Relay Outputs —K1 through K8, depending on
model.
2.5 CONTROL PARAMETERS—
PRESSURE, TEMPERATURE
AND TIMER SETTINGS
Parameters that control the operation of the machine
are viewed and set using this display. These
parameters may vary by machine model.
The Control Parameters are :
Unload pressure —The pressure where the machine
is unloaded. 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 —The pressure differential below the
unload pressure where the machine is loaded. 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).
Setpoint —(VSD packages only) The targeted
pressure 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 6 for additional
details.
Unload Time —If the machine is running in AUTO
mode, this parameter specifies the amount of time
that the machine will run unloaded 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 —If the machine has an electric
solenoid drain, this parameter and the following
parameter (Drain Time) are used to turn on the drain.
The interval is the time between activations of the
drain and the Drain Time is the length of the time
energized. This does not apply to the Sullair SCD
zero loss drain, which is not controlled or monitored
by the Supervisor.
Drain Time— Length of time that drain is energized.
Restart time—
Time to wait after power up before starting machine.
This parameter is used to keep several machines
from starting at the same time after power up, or to
delay start until other equipment is started. If
disabled parameter is zero, the machine will not
automatically start after power up. If this parameter is
a number larger than zero, the machine restarts after
a delay defined by this time. For example, if the
WARNING
Enabling this function also enables auto-
matic restart after power recovery. Be sure
to depress the Emergency Stop button to
defeat this function when automatic start is
to be prevented.
