Overview
1.1 Outlook
The OT2106A electronic engine governor speed controller(controller for short) is made of metal and
consists of circuit boards inside. All the adjustable potentiometer of circuit boards are on the panel and marked
with printed label, the terminals are arranged at the front end of the controller. The real pictures were shown in
figure 1-1.

1.2 Description
Rated Speed
Potentiometer: This is used for setting rated speed. At rated speed condition, it can make sure
that the engine speed is equal to the set value. When adjusting clockwise, speed increase; when
adjusting anti-clockwise, the speed reduced.
Start-up oil quantity
potentiometer: for engine starting enrich. This feature is automatically enabled in the
engine startup process, when the startup is over, this function will be automatically replaced by
speed control function. Adjustment range: 25% to 100% of the controller output signal, turn
clockwise will increases the start-up oil quantity.
Stable
potentiometer;
Gain
potentiometer;
Compensation
potentiometer: these three potentiometers are used
to adjust and correct the control characteristics of the amplifier circuit, so that the controller can adapt different
types of engine. Stable potentiometer is used to adjust the recovery time of dynamic process; Gain
potentiometer can adjust the biggest speed amplitude when the load has a sudden change; Compensation
potentiometer is used to adjust the response of actuators and the engine. All these three potentiometer increase
with clockwise adjustment,
decrease with c
ounter-clockwise adjust.
Rising time
potentiometer: used to adjust the speed up time when the engine runs from the idle speed to the
rated speed. Adjusting range: 5 seconds ~ 35 seconds, it will increase with clockwise adjustment.
Idle Speed
potentiometer: used to set the idle speed. In idle condition, it can make sure that the engine speed is
