Liquid level monitoring system

Product catalog summary

Installation Instructions:
- Do not seal the wire way with silicone as it will cause the PTS-XX to malfunction.
- Avoid over-tightening the PTS-XX to the tank; tighten finger tight and then an additional ¼ turn.
- Do not expose the sender to vacuum to prevent damage.

Normal Operation:
- The PTS-XX measures tank level continuously, but the display activates only when the switch is pressed.
- To check the tank level, press the corresponding switch on the LLM-2. LEDs will indicate the current tank level.

Troubleshooting:
- If the empty LED flashes, verify all connections between the PTS-XX and the LLM-2.
- If connections are correct, remove power for 20 seconds and reapply.
- If the gauge reads correctly initially but drops, the sender may have a leak and needs repair.
- If the gauge reads full constantly, recalibrate using the instructions provided. If unresolved, the transducer may be damaged.
- Ensure no plugged vents are causing a vacuum, which can damage the sender.
- For persistent issues, contact technical service at 1-866-350-9500.

System Parameters:
- Operating Voltage: 10.8V to 16V
- Max Pressure: 10 psi
- Media: Waste/Fresh Water
- Max Sender Length: 36” (1.2 psi H2O)

Optional Field Calibration Method:
- The PTS-XX can be shortened and recalibrated if necessary.
- Follow the steps to connect wires, submerge the sender, and calibrate the display for empty and full levels.
- After calibration, trim the exposed green and white wires to prevent accidental recalibration.

Determining Sender Length:
- Calculate sender length as (Height of Tank) – (1.5”).
- The 1.5” is subtracted to prevent the sender from bottoming out in the tank.

Notes on Field Calibration:
- The display lights will indicate when the liquid level rises above or drops below the calibrated empty and full points.

PTS/PFS Installation Instructions Do not silicone the wire way. Completely sealing the top of the PTS-XX will cause it to stop working. Do not over-tighten PTS-XX to tank. Thread in finger tight and then turn an additional V* turn. Do not expose the sender to vacuum. Prolonged exposure to vacuum will damage the sender. Figure 1 Wiring Schematic Field Calibration Wires .- PTS-XX must-be connected to the^Aite wire not the green wire. Normal Operation: The PTS-XX is constantly measuring tank level but to conserve power the display is only active when the To check tank level press the corresponding...

Optional Field Calibration Method If required the PTS-XX can be cut shorter and re-calibrated. (Note units are shipped 1. Connect the sender to display as shown in the figure below 2. Remove the pre-stripped sheathing from the green and white wires and connect them together. 3. Submerge the sender to the level you want the display to read empty. 4. Connect the red and black wires from the display to a 12V source. 6. Submerge the sender to the level you want the display to read full (Factory Setting is 2" from top 7. Disconnect the green and white wires. 9. Remove power and the unit is now calibrated...
