Payload Meter III - Section 60 OM6009 9/08 Page 60-8 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 potentiometer 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 should be flashing. 3. Press the “SET” button again to change the digit. Reading the Load Display 4. Press the “SELECT” button once to adjust the second digit. The lower display on the speedometer/display gauge is used for payload information.

Use the “SET” button again to change the digit PL = Payload Id = Operator ID tL = Total Shift Tons LC = Shift Load Counter LF = Left Front Suspension Pressure rF = Right Front Suspension Pressure Lr = Left Rear Suspension Pressure rr = Right Rear Suspension Pressure In = Inclinometer 10. Press the “SELECT” button one more time to enter the ID. 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.
Using the Load and Ton Counter PLMIII 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. 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. 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 dispatch systems. Total Ton Counter 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. To view the total ton counter press and release the “SELECT” switch until tL = is displayed on the gauge.
