OT2106A Electronic Engine Governor Speed Controller
9
(1) The rated speed potentiometer: Set the rated speed potentiometer at minimum (ten turns
potentiometer, counterclockwise to the end).
(2) Stability potentiometer: Set the stability potentiometer in the middle position (one turn potentiometer).
(3) Gain potentiometer: Set it in the middle position (one turn potentiometer).
(4) Rising time potentiometer: Set at minimum (one turn potentiometer, counterclockwise to the end).
(5) Idle speed potentiometer: Set at minimum (one turn potentiometer, counterclockwise to the end).
(6) Start-up fuel quantity potentiometer: Set at maximum (one turn potentiometer, clockwise to the end).
(7) Compensating potentiometers (one turn potentiometer): Set in the scale 2 position;
(8) Speed trim potentiometer: If an external speed trim potentiometer is used, set it in the middle position.
(9) droop potentiometer: If an external speed droop potentiometer is used, set it to the minimum value
(one turn potentiometer, counterclockwise to the end).
Make sure that the actuator has been connected with the terminal 9 (+) and terminal 10 (-).
4.2 Start adjustment
Before starting the engine, make sure the installation, connection, and the pre-set are correct.
Note: Make sure the controller speed set range is within the actual needs of the engine work. Emergency
stop devices should be prepared to prevent overspeed or personal property damage when starting the engine.
(1) Stability adjustment:
If the engine is in a steady state, skip this step and directly adjust the rated speed.
If the engine is seriously unstable, then slowly lower the gain (gain potentiometer,
counter-clockwise) until the engine is stable. Adjusting the gain potentiometer will change the
speed immediately, so the adjusting process should be slow.
If the engine is slightly unstable, increase the value of stability setting (stability potentiometer,
clockwise) until the engine is stable. If increasing the value of stability potentiometer setting can
not make the engine stable, you need make the following adjustments at the same time:
Slowly lower the gain (gain potentiometer, counter-clockwise);
Slowly lower gain and increase compensating potentiometers (clockwise rotation compensation
potentiometer).
(2) Rated speed adjustment:
when the engine is running in a steady state, (if an external speed trim potentiometer is used, turn
it in the middle position), adjust the rated speed potentiometer slowly, the speed will increase
