Asphalt Pavers Conveyor Electronic Control System Caterpillar

Accessing Calibration Submodes

The following table lists the availble calibration submodes for the conveyor Conveyor Electronic Control System. The submodes are accessed when the ECM is in calibration mode 2.

Note: Submodes c13 thru c18 require that the paving status is ON. THE CONVEYORS AND AUGERS WILL OPERATE DURING THESE CALIBRATIONS. The following machine conditions are required:

• The engine speed at high idle.

• The parking brake is ON.

• The propel switch in the PAVE position (LOW position for the AP1000B and BG260C).

• The propel lever in the FORWARD position.

• The conveyor, auger and feeder mode switches in AUTO.

Note: The calibration submodes are used to perform actual tests and adjustments. Only enter these submodes when performing the procedures as described.

The calibration submodes can be accessed by using the service switches (1, 2). Calibration mode 2 must be entered first. Then the calibration submodes are accessible. The ECM provides normal operation until calibration mode 2 is entered.

Entering Calibration Mode 2

1. Press and hold the ECM mode switch (1) in the SCROLL position.

2. Release the switch when "- 2 -" is showing in the display area.

The ECM now enters the calibration mode. Submode c01 will automatically be shown on the ECM display.

Entering a Submode

In order to enter a submode, first enter the calibration mode 2. The system automaticaly enters the first submode c01. The number showing on the ECM display is the submode that is currently entered. Refer to Table 1 calibration submode chart for a list of the availble submodes.

The submodes are used to perform calibration procedures. Perform the following steps in order to access the submodes.

1. Press and hold the display mode switch (2) in the INCREMENT position.

2. Release the display switch when the display is showing the desired submode number.

Each submode is associated with a specific calibration procedure for a component in the conveyor control system.

Storing A Value Within A Submode

During calibration procedures, it is necessary for the ECM to determine whether a new calibration value is acceptable. The ECM uses two indicators to inform service personnel whether or not the new calibration value is acceptable. When attempting to store a new calibration value, either the red indicator (not accept) (4) or the amber indicator (accept) (5) will flash.

In order to store a value in a submode, perform the following steps.

1. Press and hold the display mode switch in the CLEAR/STORE position. At this time, the red indicator (4) or the amber indicator (5) will flash. If the amber indicator is flashing, the calibration has been accepted. The new value is stored. If the red indicator is flashing, the calibration has not been accepted. The new value is not stored. When the new value has not been accepted, the old value for the calibration remains in memory.

2. Release the display mode switch (2). The amber indicator (5) must have flashed in order for the ECM to store and use the new value.

Return To Normal Mode

This procedure will return the ECM to normal mode 0.

1. Press and hold the ECM mode switch (1) in the SCROLL position.

2. Release the ECM mode switch when "- 0 -" is showing on the ECM display.
