16. TROUBLESHOOTING (5) For releasing “data FULL” described in (1) to (3) , see the separate manual for PLM II (Card-type payload meter) of “8.3 OPERATOR CHECK MODE, 8. OPERATION OF SWITCH”. Once “data FULL” in (4) is displayed, it can not be cleared until automatically cleared to zero. Always clear data before “data FULL” appears. For operation, see the separate manual for PLM II (Card-type payload meter) of “8.2 FORCED DISPLAY OF TOTAL PAYLOAD AND OVERALL NUMBER OF CYCLES, 8. SWITCH OPERATION”. (6) There is no priority among (1) to (4). If two or more “data FULL” occur at the same time, they are displayed one after another except when loading.
(*2)Incorrect cycle data of loading The payload-meter detects the payload based on the pressure sensing signal from the suspension. This detection functions all the time. However, during loading or immediately after loading, the detected data becomes slightly uncertain due to the dynamic friction of the suspension. To assure accuracy, the payload-meter is designed to detect and store the payload when it is free from the dynamic friction of the suspension: after traveling with load and just before dozing.
(This payload is stored as part of the cycle data.) If the operator operates dozing (handling of the dump lever) before the body vibration (pitching) settles down, the payload stored in the payload-meter could be inaccuracy. The stored payload could be also inaccuracy, if the machine stops suddenly or climbs a chocks, or if it bumps obstacles. Thus, if dozing is done before the vibration of the body settles down, the payload-meter sends a warning to the operator, displaying “Incorrect payload data “ shown in the abnormality/warning chart. In this case, the detected payload is stored.
WARNING When parking the machine in a disposal area, avoid braking abruptly, climbing chocks and rocks, or bumping obstacles. Carry out dozing by the dump lever, after the machine parked safely in the disposal area and the vibration settled down. (Operation of the dump lever should be done after 3 seconds or longer elapsed.) Make the disposal area as flat as possible and the road surface as level as possible. 2-128
