Caterpillar Monitoring System (Speedometer module is not present on the AP-1055D/BG-2455D machines) (1) Speedometer module. (2) Main display module. (3) Odometer units. (4) Speed readout. (5) Speedometer units. (6) Display area. (7) Six digit display area. | |
Note: The AP-1000D, AP-1055D, BG-260D, and BG-2455D machines are not equipped with a speedometer module. Any reference to the speedometer components applies to the AP- 655C/BG2255C machines only.
The units mode is mode 5. The units mode is used to toggle the displays of the monitoring system between US and Metric units of measure. When the main display module enters units mode, six digit display area (7) shows the current setting. The display reads "US" when the mode is set to US units. The display reads "SI" when the mode is set to Metric units.
When the units mode is set to US units, the speed readout (4) on the speedometer (1) will be in feet per minute or "MPH" (depending on the speed that the machine is moving). When the units mode is set to Metric units, the speed readout on the speedometer will be in meters per minute or "km/h" (depending on speed that the machine is moving).
In order to toggle the units, ground the clear input while the service input is open. The units continuously toggle when the clear input is grounded. Opening both of the inputs will set the main display module to the currently displayed setting.
