OM6008 02/03 Optional Equipment - Section 6 Payload Meter III Page 6-19 There are also many configuration and download options available from this screen. The Connection Menu is updated only when the connection is first made. It does not update automatically. To view changes made while connected, the user must close the window and reconnect to the payload meter. Setting the Date and Time The time shown on the form is the time transmitted from the payload when the connection was first established. The connection menu is displayed after a serial connection has been established and the PC software has connected to the payload meter.
Connecting to the Payload Meter Communications to the PLMIII requires a laptop computer running the PDM software. The software connects to the payload meter through the meter's serial port #1. This is the same port used by the speedometer/display gauge. When the laptop is using the serial port, the lower display on the operator gauge on the dashboard will be blank. This does not affect the operation of the speedometer. The date and time are maintained by a special chip on the PLMIII circuit board. The memory for this chip is maintained by a very large capacitor when the power is removed from the payload meter. This will maintain the date and time settings for approximately 30 days.
After this time, it is possible for the payload meter to lose the date and time setting. It is recommended that the system be powered every 20 days to maintain the date and time. If the date and time is lost, simply reset the information using this procedure. It takes approximately 90 minutes to recharge the capacitor. Connect the laptop to the system using the EF9160 communications harness. The download connector is typically located on the housing mounted in the cab to the back wall. The PLMIII system uses the same connection as the Payload Meter 2 system. Configure the Payload Meter Configuration of the payload meter requires a serial connection to the PLMIII system.
Clicking the "Configure Payload Meter" button will bring up the Truck Configuration screen and menu. This screen displays the latest configuration information stored on the payload meter. Changing the date and time will affect the haul cycle in progress and may produce unexpected results in the statistical information for that one haul cycle. When changes are made to the configuration, the "Save Changes" button must be pressed to save the changes into the payload meter. To confirm the changes, exit to the main menu and re-connect to the payload meter. To change the time: 1. Click on the digit that needs to be changed. 2. Use the up/down arrows to change or type in the correct value. 3.
Press the "Save Changes" button to save the new time in the payload meter. To change the date: 1. Click on the digit that needs to be changed. 2. Type in the correct value or use the pull-down calendar to select a date. 3. Press the "Save Changes" button to save the new time in the payload meter.
