Set Up Set Up • • • • • Do not install or service this equipment unless you are trained and qualified. Installing and servicing this equipment requires access to parts which may cause fire, explosion, and serious injury if work is not performed properly. Read warnings, page 2. There are 8 Network ID's and 8 Transceiver ID's possible by changing the position of the dipswitches. The eight positions are identified as 1, 2, 3, 4, 5, 6, 7 and 8. See FIG. 2 and FIG. 3 on pages 4 and 5.
Set Up 7. Install two, 9-volt alkaline batteries (1). Be sure that the batteries fully engage the mounting clips by pushing on the bottom of each battery with your thumb. It will take about 30 seconds for the monitor to display information after pressing the Display button on the initial power-up. This time will decrease thereafter to a few seconds 9. Replace cover (7) and secure it with the four screws (3).
Set Up Dipswitch Setting for Network ID and Transceiver ID See FIG. 3 for dipswitch setting configurations. b The batteries must be disconnected and removed before changing dipswitch settings or the TLM will not be able to communicate with the PC software.
Set Up Registering the TLM Graco recommends registering TLM prior to installation. See FIG. 4 for display messages you will see during Registration Mode. The TLM operating parameters are controlled by the Matrix PC Software and setup by the System Administrator. See the Matrix 3 Software instruction manual for the PC setup instructions. To register the TLM: 1. Set TLM to correct NETWORK ID and TRANSCEIVER ID (see Dipswitch Settings, page 5). 2. Press and hold the Display button (A, FIG.
TLM Display TLM Display (See FIG. 6, page 8) TLM ID - Unique number assigned to the TLM to distinguish it from other TLM’s in the system. Battery Life - Remaining life of the unit’s batteries. System Administrator on Matrix PC Software determines when Low Battery Warning message is generated. Battery life is dependent on the number of readings taken per day. Network ID and Transceiver ID - Shows the Network ID and Transceiver ID TLM is using (also see page 3).

If button is not pushed, the TLM will automatically read correctly at the next scheduled tank reading. Daylight Saving Time (DST) Change B A FIG. 8 Press and release the Display button (A).
Troubleshooting Troubleshooting Problem Cause Solution Brand new monitor’s display is very dim. Unit is shipped with protective coating over display. Remove protective coating. Monitor displays “Invalid Reading”. The TLM reading is outside of the programmed size parameters. Verify the programmed parameters and re-program the TLM if necessary. Monitor will not register. Transceiver is not powered-up. Verify transceiver is powered-up Attempt to program while red lights on transceiver are lit.
Troubleshooting Problem Monitor readings are inaccurate. Cause Solution Tank geometry incorrectly defined. See Tank Level Monitor Software Guide or PC Software Guide for details. Tank Level Monitor has not been updated with latest adjustments made within The profile ID on the PC. Manually push DISPLAY button on TLM Two TLMs are programmed to the same address. Verify that each TLM is correctly programmed to a unique address.
Service Service Once the Tank Level Monitor has been installed, no additional maintenance or service is necessary, with the exception of replacing batteries. Replacing Batteries Always replace both batteries with two new 9-volt alkaline batteries whenever you change batteries in the TLM. Sparking can occur when changing batteries. Only replace the battery in a non-hazardous location, away from flammable fluids or fumes. 1. Remove the four cover screws (3) and cover (7). 2.
