This document addresses the

Class1

Tank Le vel Gauge with four outputs and the installation,

calibration and operation of this unit.
The module has four (4) positive (12 VDC) outputs capable of sourcing 7.5 Amperes each.
Output indications with tank level decreasing:

Full Light 3/4 Light 1/2 Light 1/4 Light

Full to 7/8 tank ON ON ON ON
13/16 to 3/4 tank Flash ON ON ON
3/4 to 5/8 tank OFF ON ON ON
9/16 to 1/2 tank OFF Flash ON ON
1/2 to 3/8 tank OFF OFF ON ON
5/16 to 1/4 tank OFF OFF Flash ON
1/4 and below OFF OFF OFF Flash

Output indications with tank level increasing:

Full Light 3/4 Light 1/2 Light 1/4 Light

1/8 and below OFF OFF OFF Flash
3/8 to 1/4 tank OFF OFF Flash ON
1/2 to 3/8 tank OFF OFF ON ON
5/8 to 1/2 tank OFF Flash ON ON
3/4 to 5/8 tank OFF ON ON ON
7/8 to 3/4 tank Flash ON ON ON
Full to 7/8 tank ON ON ON ON

Fault Indications:
1/4 and Full lights alternately flashing and COM LED flashing

Invalid calibration (recalibrate system)

1/4 and 1/2 lights rapidly counter flashing and COM LED flashing

Transducer Fault (check wiring and transducer)

3/4 and Full lights rapidly counter flashing and COM LED flashing

Transducer shorted to 5 volts (check wiring and transducer)

1/2 and 3/4 lights rapidly counter flashing and COM LED flashing

System Fault (repo wer system, if prob lem repeats , recalibrate unit and if
the error is not resolved, replace display)

FLUID TANK

3/4 NPT Elbow (OEM)

The transducer must be mounted vertically as depicted to insure an accurate and reliable reading.
This will also prevent damage to the transducer from freezing.
Harnesses are supplied with a cable to connect the transducer.
Loose wires with appropriate terminals for the outputs and ground are including to facilitate installation.

Pressure Transducer
1/4 NPT

Adapter 3/4-1/4 NPT Bushing (OEM)
Foam adapter is supplied when a
foam level system is ordered.

The transducer measures the column of water in the tank above the opening of the elbow.
When calibrating for a full tank it is important that the tank not be overfilled. If the fill opening or
tank vent is above the transducer, care should be taken not to have water in this area when
calibrating the tank level gauge. The transducer should never be mounted in the sump area
because of sludge and potential inaccuracies in calibration.

Mount a 3/4 NPT elbow just off the bottom of the tank, enough to keep sediment out of the
elbow and transducer (PN 102162). Attach a 3/4 to 1/4 NPT adapter (supplied for foam) to the
elbow and mount the transducer to that. The elbow and adapter need to be installed so that
the transducer is mounted vertically.
