Body Up Input The body up signal is critical to proper payload meter operation. The payload meter starts a new haul cycle when the body comes down from dumping the last load. If the payload meter cannot sense the body up and down, it will not begin recording haul cycles. Confirm that the dashboard indicator for body-up is working properly. If not, check the connections at the body up switch. This switch is a magnetic reed switch. The switch may fail or the plate that triggers the switch may be mis- aligned. Refer to the appropriate shop manual for the proper procedure for adjusting the switches. NOTE:
The input to the payload meter is ’live’ and can be checked by raising and lowering the body or using a large washer to trigger the switch. M20007.2 3/02 Payload Meter II™ Troubleshooting M20-49
