2.5 Adjustments and Setup Procedures
Warning: The following procedures will require engine operation. Be sure to
follow all safety guidelines and wiring procedures.
The rear of the ES52 controller contains 4 adjustable pots, and 9 DIP switches.
Potentiometer (Pot) Adjustment
“Potentiometer” is abbreviated as “pot” throughout. To increase a pot’s setting, turn it
clockwise. To decrease it, turn it counter-clockwise. On board Pots are 20 turns nominal,
therefore turn pots fully 20 turns to ensure that you are at either the minimum or maximum
setting.
Potentiometers are shown below as they appear on the rear of the ES52 series units
1. Crank Disconnect
2. Over-Speed
3. Crank/Rest
4. Timer
It takes approximately 20 turns to go to the minimum or maximum value. Turning the pot
counterclockwise decreases the setting. Turning the pot clockwise increases the setting.
Each pot has a clutch to protect from overturning and thus potentially requires one to two turns to
overcome this clutch if the pot is at the minimum or maximum position before the value actually
starts changing.
