WIRING

Master – Only pins 1, 5, 6, 7, 12 are required for a system that

Dim – Apply positive voltage (+VIGN) to Pin 4 to dim the
display.

PRESSURE TRANSDUCER MOUNTING

Mount the pressure transducer (sensor) vertically to insure an
accurate reading and to reduce the possibility of sensor port
contamination.

MAGNETIC SWITCH ACTIVATION

A magnet is required to activate
the magnetic switches in order to
enter passwords.

Each magnetic switch activation
must occur within 2 seconds of
the last or the password will be
reset.

The left column of LEDs will light
when the LEFT (L) magnetic
switch is activated.

The right column of LEDs will light
when the RIGHT (R) magnetic
switch is activated.

Activate a magnetic switch by using an in-and-out motion starting
from approximately two inches away from the bezel.

Do not use a swiping action.

1 POINT CALIBRATION (FULL)

1.

FILL the tank. Enter the password RLLR LRRL to store the
calibration. Unit flashes top row of LEDs, then displays FULL
(all LEDs on). Calibration complete.

2 POINT CALIBRATION (EMPTY, FULL)

1.

Enter the password RLLR LLRL to enter 2 point calibration
configuration mode. Unit flashes the two center rows of LEDs
twice. Unit indicates EMPTY (cascading the LEDs).

2.

Ensure the tank is EMPTY. Activate the RIGHT switch to
store this point. Unit flashes top row of LEDs, then displays
FULL (all LEDs lit).

3.

FILL the tank. Activate the RIGHT switch. Unit flashes top
row of LEDs, lights the two center rows of LEDs, then displays
FULL (all LEDs lit). Calibration complete.


Make certain that the FULL point used for tank calibration is
approximately 1 inch [2.54 cm] to 2 inches [5.08 cm] from the
physical top of the tank.

Do not calibrate the FULL point with the water level up into the fill
tower.

OPERATION

During power up the display will individually cycle on each LED
starting with the bottom LED. The unit will then show the custom
scroll text and then show the current tank level information.
