01058 rev. C VERNIER THROTTLE SYSTEM for CUMMINS CELECT and CELECT PLUS ENGINES Class1 607 NW 27 Ave. Ocala, FL 34475 Ph: (352) 629-5020 Fax: (352) 629-2902 DOC 101058C_c:\manuals\throttles\cummins\cumthrot.
Overview Throttle Interface Control Module System Overview The Class1 Vernier Throttle Interface is designed to allow industry standard vernier style controls (such as the Felsted Electronic Vernier II Control) and other potentiometer controls to be used with electronically controlled engines. This unit will work with electronically controlled Cummins Engines (Celect and Celect Plus) using the J-1922 control data bus to send control signals to the Engine Control Module (ECM).
Interlocks Class1 provides a variety of engine controls that are used in a broad range of applications, therefore it is impossible for Class1 to determine the suitability of a particular control for any specific application. The flexibility of our products allows them to be used in a limitless number of custom applications. Class1 can advise you of the features that are available on a given product so that you can determine what product will meet your needs.
Error Codes Error Codes The Class1 Vernier Throttle Interface continuously checks for several errors. Errors are displayed on the green diagnostic LED. When an error is detected, the error number is flashed on the LED. Example: If the data link is not detected, (error 2) the LED will flash twice, pause two seconds and repeat while the error is present. Defined Errors ERROR 1 Thottle Error This error occurs when the controller does not detect an idle throttle position.

Operation When the throttle interface module is powered up by the safety (interlock) system the throttle module will perform a self check and the LED on the module will turn on and then turn off after the self check if everything passes. (approx. 4 secs) After the self check, the interface will verify that the throttle is fully closed. If the throttle is not fully closed, the LED on the interface module will flash once every 2 seconds until the zero position is detected.
