HI LPB SERIES LOAD POINT ASSEMBLY

Remedy:
Step 1. Tie together the load sensor excitation (2),
signal (2) and ground (1) wires.
NOTE: Be careful NOT to include the two C2 wires.
Step 2. Use a megohmmeter and measure the
resistance between all five wires tied
together and the load cell metal body. The
measured value should be 5,000 megohms
or more.
WARNING WHEN USING A MEGGER DO NOT EXCEED
50 VOLT RANGE.
Step 3. If the sensor fails this test remove the
ground wire and test with only the four
live leads.
Step 4. If the sensor passes the test an insulation
problem in the cable is most likely.
Step 5. Replace the load cell if the cell fails both
tests.
