value. If during a change the ESC key is pushed,
editing is terminated and the original value is reset.
The left and right arrow keys can be used to move
to other digits or letters in a value. For example to
change a value from 100 to 500, the left arrow key
can be used to position the cursor to the 1 digit in
the 100, and the up arrow key used to increment
the digit to 5.
Text fields can also be edited in the same manner.
Push the enter key to start the edit, use the left and
right arrow keys to move to the letter to be changed,
then use the up and down arrow to change the let-
ter. Push the enter key to complete the edit.
The following are detailed descriptions of the vari-
ous displays.

5.4 STATUS - CURRENT PRESSURES, TEMPERA -

TURES, 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 T5 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 time 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

5.5 CONTROL PARAMETERS - PRESSURE, TEM-

PERATURE 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
(7.6bar) and the load differential is set to 10 psid
(0.7 bar), the machine will load when the line pres-
sure goes below 100 psi (6.9 bar).

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 exam-
ple 5), there may be times when the machine will
run unloaded for more than 5 minutes. This is
because there is another timer that keeps the
machine from being started more than four times an
hour.

Drain Interval -

If the machine has an optional elec-

tric 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 mon-
itored by the Supervisor.

Drain Time -

Length of time that drain is energized.

Restart time -

Enabling this function also enables automatic
restart after power recovery. Be sure to depress
the Emergency Stop button to defeat this func-
tion when automatic start is to be prevented.

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 dis-
abled parameter is zero, the machine will not auto-
matically 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
Restart Time is set to 10 seconds, then the machine
will be enabled to start after 10 seconds.

Wye to delta transition timer -

Also used to con-

trol the closed inlet start valve. Disable by setting to
zero (0)-full voltage start (standard for full voltage
start). Requires approximately 4-6 seconds for wye-
delta or solid state starting.

Modulate -

If set to “No” the spiral valve and inlet

valve modulation control are disabled, and the
