Optional Payload Meter (Plm Ii) Check-Out Procedure - Komatsu 830E Shop Manual

9.0 OPTIONAL PAYLOAD METER (PLM II) CHECK-OUT PROCEDURE

9.1 Check The Deck Mounted Lights
Turn the payload meter system on by switching the truck key switch to the On position. The payload
meter automatically runs a 10 second self test. During the self test the deck mounted lights are On. If
they are not all lit, check connections, wiring and bulbs. After successful completion of the self test,
the time of day or "O" will be displayed depending on whether the brake lock switch is Off or On
respectively.
9.2 Check Pressure Sensors
Turn the payload meter On. Allow the payload meter to run through its self test. Disconnect one pres-
sure sensor at the suspension cylinder. An error code ( refer to table) will be displayed on the pay-
load meter after five seconds. Check the error code and re-connect the pressure sensor. Clear the
error by pushing the "Cal" button on the payload meter. Complete checking all four pressure sensors
with the same procedure.
NOTE: In some earlier units on 685E, 630E, 510E, 445E model trucks the rear compo-
nent harness has 39FA & 39FD reversed. To correct this reverse the circuits of the rear
component harness at terminal board TB5C in the 24 volt junction box. Be sure to rela-
bel circuits. Reference the payload meter kit installation drawing of the particular model
truck.
9.3 Check Operation of Data Storage Trigger Module
Drive to a loading area, stop the truck, switch the brake lock On and put a load in the body of the
truck. Do not exceed the load limit. When finished loading, the payload meter display should indicate
the tons of material loaded into the truck. Switch the brake lock Off. The display should change to O
for one second then change to the time of day. Switch the brake lock On. The display should change
back to the tons loaded without indicating O for one second.
9.4 Zero The Angle Sensor
Park the loaded truck on a 0% grade. Refer to the Options section of this service manual for opera-
tion of the payload meter system diagnostics. Put the payload meter into the check mode and call up
the slope on the display. Loosen the three angle sensor mounting nuts and rotate the angle sensor
until 0.0 is indicated on the display. Then re-tighten the mounting nuts.
9.5 Check Body Up Switch Function
Drive the loaded truck to the unloading area. Dump the load. The payload meter display should indi-
cate 0 when the body is off the pads.
