DCA-220SSJ/SSJU — DIAGNOSTIC DISPLAY

Figure 6. Diagnostic Display Panel

The diagnostic display panel located inside the control box on the generator (Figure 6) is designed to meet the needs for instrumentation and control of electronically controlled engine communication using the SAEJ1939 Controller Area Network (CAN). This diagnostic display is a multifunction tool that enables equipment operators to view many different engine parameters and service codes.

The keypad on the diagnostic display panel is a capacitive touch sensing system.There are no mechanical switches to wear or stick. This keypad (display unit) will operate in extreme hot or cold weather conditions.

Other components in the system are microprocessor-based components for displaying critical engine data broadcast by an electronic engine or transmission’s Engine Control Unit (ECU): engine RPM, oil pressure, coolant temperature, system voltage, etc., and a combination audible alarm and relay unit for warning and shutdown annunciation.

The Engine Control Unit (ECU) used with this generator diagnosis engine faults that arise with the the engine control system and the engine itself. Engine faults can be determined by viewing the DiagnosticTrouble Codes (Active Fault Codes) which are displayed on the Diagnostic Display Panel. See the John Deere Engine Operator’s Manual for a complete listing of active fault codes and countermeasures.

The following definitions describe the controls and functions of the Diagnostic Display Panel (Figure 6).

1.Menu Button – Press this button to enter or exit menu screens.

2.Left Arrow Button– Press this button to scroll through the screen either moving the parameter selection toward the left or upward.

3.Right Arrow Button – Press this button to scroll through the screen either moving the parameter selection toward the right or downward.

4.Enter Key Button – Press this button to select the parameter that is highlighted on the screen.

5.Emergency Stop LED – When lit (RED) indicates a major fault has occured. This condition will shudown the generator.

6.Warning LED – When lit (AMBER), indicates a engine parameter has exceeded its limits (minor fault). The generator will still run in this condition.

7.Display Screen – Graphical backlight LCD screen. Back lighting is controlled via menu or external dimmer potentiometer. The display can show either a single parameter or a quadrant display showing four parameters simultaneously.

8.Diagnostic Switch – When placed in the ON position, will activate the diagnostic display panel.

9.CAN Diagnostic Connector – Controller Area Network connector. This connector outputs diagnostic error codes. Connect a scanner or similar device into this connector to read error codes.
