Engine Control
Overview
Many electronically controlled engines can be remotely operated by using an Analog throttle control
signal. Some engine software must be configured for remote operation, check the engine application
manuals for details. This programming should be accomplished whenever required for installing a
remote throttle device.
Operation
Class1 offers Vernier throttle controls and interfaces for specific engine applications and pressure
governor control systems that utilize the remote throttle input of the engine ECM.
Variable Throttle Control When the remote throttle is enabled, variable engine control is available
to the operator using the remote throttle input. Some engines perform an idle validation, if the remote
throttle is open when the throttle is enabled, the engine ECM will maintain the engine at idle RPM until
the throttle is closed and then re-opened. This feature prevents sudden unexpected increases in
engine speed when the unit is initially activated. See the appropriate engine manual for application
specific information. Other engines do not validate idle. If the throttle is left open and the remote throttle
is turned on, the engine will respond by increasing RPM to the remote throttle setting. Caution should
be exercised whenever enabling this type of throttle.
High Idle Control A High Idle signal can be used to bring the engine speed to a pre-determined
engine RPM (High Idle) from a remotely mounted switch or load management device. This speed can
be set by an external potentiometer, a resistor network or a switch input and is an integral function of
the Class1 Pressure Governors.
Wiring Interface wiring is straight forward and can consist of 2 to 5 wires dependent on the
engine application. Refer to the diagrams in this manual for wiring examples.
Refer to the engine manufacturer’s Electronic Application & Installation Guides for detailed information
on engine electrical interfacing.
