OPERATION

PAGE C − 3

b) USr CAL... User calibrate mode, i.e.,

user wants to calibrate unit.

c) SEt a.oF...

A OFF setpoint, units of lev-
el.

d) SEt a.on... A ON setpoint, units of level.

e) SEt b.oF...

B OFF setpoint, units of lev-
el.

f) SEt b.on... B ON setpoint, units of level.

g) Hrn dLy...

Horn on, A output delay
time, 5−30 seconds, in
5-second increments.

h) LO BAT...

Indicator, shows battery
voltage level is below
12VDC.

i) Lo tpt...

Shows status of Low Tem-
perature Thermostat con-
tacts.

2. LEDs:

a) When the green LED is lighted, the unit is

showing level on the LCD display.

b) When the A output LED is lighted, the A

output relay is closed.

c) When the B output LED is lighted, the B

output relay is closed

NOTE

LED’s and all segments of the display are lighted
upon connection of power as a lamp test feature.
However, no relay outputs are closed during test.

3. Switches:

a) The

switch functions as a round rob-

in" type switch. Pressing this switch will
cause the unit to show the next selection
in the order listed above.

b) The

switch functions to decrease the

selection showing. This switch can be
used to decrease the smallest digit by

bumping" the switch, or to continuously

decrease the digit by pressing and hold-
ing for at least one second and releasing
when desired setting is reached.

c. The

switch functions to increase the

selection showing. This switch can be

used to increase the smallest digit by

bumping" the switch, or to continuously

increase the digit by pressing and hold-
ing for at least one second and releasing
when desired setting is reached.

Liquid level adjustment of the Electronic Pressure
Switch is accomplished using the three buttons on
the control. For EPS functions and level adjust-
ment, refer to the following instructions.

EPS Functions

Actual functions of the control occur as follows:

Power is applied to the unit.

Unit performs display test for approximately 4
seconds.

When the pressure level showing is equal to or
greater than the A.on" setpoint, the Horn out-
put contacts will close in approximately 1 sec-
ond and a delay, equal to the Hrn dLy" time,
will occur before the A output contacts close.

When the level showing is equal to or greater
than the B.on" setpoint, the B output contacts
will close in approximately 1 second.

When the pressure decreases to a level equal
to or less than the B.of" setpoint, B output
contacts will open in approximately one sec-
ond.

When the pressure decreases to a level equal
to or less than the A.of" setpoint, A output con-
tacts will open in approximately one second.

If an optional Low Temperature Thermostat is
connected to the unit and the thermostat con-
tacts close, the unit displays lo tpt" on the dis-
play. In approximately 1 second, the Horn out-
put contacts close, then after the Hrn dLy"
time, A output contacts close. A output con-
tacts will remain closed as long as Low Tem-
perature Thermostat contacts are closed.

When the Low Temperature Contacts open, A
output contact will open only if the level is
equal to or less than the A.off" setpoint.

As long a the Low Temperature Thermostat
contacts are closed, the display will show lo

tpt" unless

switch is pressed to display

some other information. Level is not viewable
until the Low Temperature Thermostat con-
tacts open.
