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.

Press and hold both switches for two (2) seconds. Both LED's will illuminate.
Release both switches. Both LED's will Flash at the same time.
Press the switch for the calibration you will perform first. (Full or Empty) You can start with either, this example will use FULL.
The FULL LED will start to flash rapidly. The EMPTY LED should turn off.
With the tank filled, press the FULL calibration switch for 1/2 second.
The FULL LED will turn on steady for 1/2 second and then turn off. The EMPTY LED will start flashing at a rate of once per second.
Press the EMPTY switch. The flash rate will increase.
Empty the tank and then press the EMPTY switch again.
The EMPTY LED will come on steady for 1/2 second and then both LED's will turn on steady and then turn off. The outputs will indicate the current tank level. Level Calibration is complete.

Press and hold both calibration switches for two (2)
seconds. Both calibration LED’ s will illuminate .
Release both switches. Both calibration LED’ s will
flash as well as the Full output and the 1/4 tank output.
With the tank either empty or full, press the switch associated with the condition of the tank (empty or full) that you are calibrating. The LED, Output and the COM LED will come on for 1/2 second and then go out. The opposite calibration LED , output and the COM LED will flash at a rate of once per second.
Press the switch associated with the flashing cali­bration LED . The flash r ate will increase.
Either empty or fill the tank as appropriate. Allow the water level to stabilize and then press the calibration switch under the flashing LED. (hold for 1/2 second) Both calibration LED’ s will come on steady , The outputs will indi­cate the current tank level and the COM LED will return to a steady green.

Press and hold both switches for two sec­onds. Both LED’s will illuminate.
Release both switches. Both LED’s will be on steady. Ensure that the tank is full.
Press the full switch and hold until the EMPTY LED turns OFF . You can start with either an empty or a full tank. This ex­ample uses the a full tank to start with. The FULL value has been stored
The FULL LED will be flashing rapidly. Drain the tank to the 3/4 full mark Press and hold the FULL switch until the EMPTY LED turns ON. The 3/4 value has been stored.
Both LED’s are now flashing slo wly. Drain the tank to the 1/2 full level. Press and hold both switches until the FULL LED turns OFF . The 1/2 tank value has been stored.
The empty LED will be slowly flashing. Drain the tank to the 1/4 level. Press and hold the EMPTY switch until the FULL LED turns ON. The 1/4 tank value has been stored.
The EMPTY LED will be flashing rapidly. Press the EMPTY switch until the LED stops flashing. The calibration procedure is complete. Both LED’s should be OFF.
The COM LED will turn off.
The COM LED wll flash. The Full and !/4 outputs will be steady ON.
The COM LED will be flashing rapidly. The first volume point is now stored. The output for the 3/4 calibration point will turn ON.
The current tank level is stored and associated with 3/4 full level.
The 1/2 tank output will turn on and the COM LED will flash slowly. The current tank level is stored and associated with half tank volume.
The output for the 1/4 tank calibration point will tur n on and the COM LED will continue flashing at the slow rate. The 1/4 tank value is stored.
The COM LED will flash quickly. Empty the tank the 1/4 output will be flashing rapidly. Press and hold the switch under the EMPTY LED until it remains steady. The cur­rent transducer value is stored and associated with empty . Outputs will now indicate the current tank level and the COM LED will be steady.
