OM6005 11/01 Optional Equipment - Section 6 Payload Meter II Page 6-29 SUSPENSION PRESSURE SENSOR The pressure sensors are mounted on top of each suspension cylinder. The sensors produce a voltage signal from 1 - 5 volts output. The pressure sensor is mounted to the suspension cylinder using a Schrader Valve assembly, adapter and sensor. The sensor can be replaced without releasing the pressure in the suspension by remov- ing the sensor with the adapter. Removal FIGURE 3-10. BATTERY CONNECTION After Replacing the Battery While replacing the battery, the backup power source for the memory inside the payload meter is momen- tarily disconnected.
This can allow unwanted data (garbage) to enter the memory and affect the meter's recognition procedures. The following will remove this unwanted data. 1. Turn the keyswitch to the ON position. may flash. 2. Using the Operator Check Mode, set the speed limit option code, time and date. (These were erased from memory when the battery was dis- connected). 3. Without turning the keyswitch to the OFF posi- tion advance to the start position. With the engine running, the display: may flash. 4. Perform the calibration procedure. Refer to "Calibrating a Truck". 5. Load the truck to the rated payload, or close to it. Dump the load. 6.
Move the truck to a safe area, wait at least 5 seconds after dumping the load, then shut the truck down. 7. Turn the keyswitch back to the ON position but do not start the engine. 8. Perform the Data All Clear in the Operator Check mode. 9. Forcibly clear the data for the total payload and overall number of cycles. With this operation performed, all the unwanted data inside the payload meter is cleared. Except for the calibra- tion data, all the data recorded in the previous steps is also erased. 10. After this procedure has been performed the system is ready for normal function. Ensure togethe comple result i suspen 1. Di Note: T prevent sensor assemb recharg 2. Ho re 3.
