Appendix C: Troubleshooting the
Load Disc System
This section describes an output check and some common
problems. For each problem, one or more possible explana-
tions are listed. For each explanation, suggested solutions
are provided.
1. Mesure the output of the load cell using procedure from
page 2-2.
2. Verify the output to be between 0mV and +/- 1mV, stable.
3. Repeat Steps 1 and 2 for each LD3xi.
4. If the load cells are installed under the vessel, verify
stability of each load cell.
Note: The “no-load”
condition is when the
Load Disc stands
alone without any
weight applied.
Functional Check: Measuring Output
(while wired to Signal Processor)
The following will be true between 0 °F and 100 °F:
1. Measure between the disconnected excitation wires and verify the
resistance to be 700 ohms +/- 15 ohms, with a stable reading.
2. Measure between the disconnected output wires and verify the
resistance to be 700 ohms +/- 15 ohms, with a stable reading.
Functional Check:Measuring Resistance
Note: When using the 61-6036-01 trim
box, and a sensor fails, the sensor must
be replaced. When the sensor wires are
removed from the junction box, the
jumper must be soldered back in place.
