INITIAL SETUP OF PAYLOAD METER There are several things that must be checked and programmed when a payload meter is first installed. 1. Check the switch settings on the side of the meter. 2. Check the Operator Check Mode settings 3. Check the Service Check Mode settings 4. Calibrate the clean truck. The next few pages show the steps required to perform these checks. Only after all of these steps have been performed can the payload meter be released for service. Switch Settings 930E-2 trucks are equipped with 53/80R63 series tires and require small changes to the switch set- tings of the PLM ΙΙ . The tires have a larger rolling radius than the PLM ΙΙ assumes.
This causes the PLM to underestimate distances by 1%. The Speed Regulation and Distance Regulation switches should be switched to position 6. This is contrary to what the label may say. Additionally, the payload gain on 930E- trucks also needs to be adjusted. The front suspensions are larger than the original 930E suspension, and there- fore, data programmed into the payload meter is not completely accurate. The gain must be increased by 1%. There are two methods for changing this gain; changing the UP factor using the buttons on the front panel, or using the gain adjustment potentiometer on the side of the meter. The preferred method is using the potentiometer.
Refer to "Adjusting the Gain". Figure 20-6. There are nine switches located behind the panel on the left side of the payload meter. Figure 20-6 shows the switch numbers. The following switch positions should be confirmed before the meter is installed. * Set switch 4 for the appropriate model.
