Payload Meter III - Section 60 08/06 OM6008 Page 60-10 OPERATOR’S DISPLAY AND SWITCH Using the Operator ID The current operator ID number is recorded with each haul cycle. The number can be between 0 and 9999. Reading the Speedometer The top window of the speedometer/display gauge is the speedometer section. The display shows the speed indicated by the frequency being received by the gauge. This can be adjusted using the potentiom- eter on the back of the gauge. In addition, the units for the display can be changed. Terminal #4 controls the displayed units. If #4 is grounded, the display will be metric. If terminal #4 is left open, the display will be in English units.
To set the Operator ID: 1. Press the SELECT switch until Id= is displayed. 2. Hold the SET button until 0000 is displayed. The first digit will be flashing. 3. Press the SET button again to change the digit. 4. Press the SELECT button once to adjust the second digit. Reading the Load Display The lower display on the speedometer/display gauge is used for payload information. The SELECT posi- tion on the operator switch allows the user to scroll through a number of useful displays. The order for the displays is as follows: 5. Use the SET button again to change the digit. 6. Press the SELECT button once to adjust the third digit. 7. Use the SET button again to change the digit. 8.
Press the SELECT button once to adjust the fourth digit. PL = Payload 9. Use the SET button again to change the digit Id = Operator ID 10. Press the SELECT button one more time to enter the ID. tL = Total Shift Tons If no buttons are pressed for 30 seconds, the display will return to normal operation. The number being entered will be lost and the ID number returns to the previous ID number. LC = Shift Load Counter LF = Left Front Suspension Pressure Using the Load and Ton Counter rF = Right Front Suspension Pressure PLM III allows the truck operator to monitor and track the total tons hauled and the number of haul cycles during the shift.
This display can be cleared at the beginning of each shift to allow the operator to record how many loads and tons have been hauled during the shift. Lr = Left Rear Suspension Pressure rr = Right Rear Suspension Pressure In = Inclinometer Total Ton Counter The display holds the displayed information until the SELECT switch is pressed again. The suspension pressures, inclinometer, and payload displays are based on current sensor inputs. The total ton counter records the number of tons hauled since the last time it was cleared. This display is in 100’s of tons. For example, if the display shows 432 , the total tons is 43,200.
This display can be cleared at the beginning of each shift to allow the operator to record how many tons have been hauled during the shift. The units are selected using the PC software. Communications to the display use the same serial link as the download connection. Whenever another computer is connected to serial port #1 to download or configure the system, the lower display will blank. This is not the same connection used by mine dis- patch systems. To view the total ton count, press and release the SELECT switch until tL = is displayed on the gauge.
