•

An overspeed shutdown device, independent of the governor system, should be used to prevent loss of

engine control which may cause personal injury or equipment damage.

•

Do not rely exclusively on the governor system electric actuator to prevent overspeed. A secondary shutoff

device, such as a fuel solenoid must be used.

When wiring eSD5500-II Series controllers:

Use shielded cable for all external connections to the eSD controller.

One end of each shield, including the speed sensor shield, should be grounded to a single point on the ESD case.

Terminal A, B, E,and F should be 16 AWG or larger. Long cables require increased wire size to minimize voltage drops.

Magnetic speed sensors Terminals C and D must be twisted and or shielded for the entire length.

The gap between the speed sensor and the ring gear teeth should be smaller than 0.02 in [0.5 mm] usually backing out 3/4 turn after

touching ring gear teeth. Speed sensor voltage should be at lease 1 V AC RMS during cranking.

Terminal P is used to supply +10 V DC regulated supply to accessories. No more than 20 mA of current can be drawn from this supply.

Ground reference is Terminal G. A short circuit in this terminal can damage the speed control unit.

Do not over-tighten terminals. Torque to no greater than 9.0 in-lb ±2.5 [1.01 ±0.28 N∙m].
