This controlling device is intended to be put into service only upon incorporation into an engine prime mover system that itself has met the requirements of the above Directive and bears the CE mark.

Speed and Phase Matching with an SPM-A Synchronizer 

Connect the SPM-A (optional equipment) wires to terminals 15 (+/–) and 16 

(com). Use shielded wire and connect the shield to the ground. 

Auxiliary Input 

Terminals 17 (–) and 15 (+) are used for auxiliary input from a load sensor. Use 

of the load sensor and parallel lines allow the 2301A Speed Control to be used in 

isochronous load-sharing circuits. If the load sensor is not used, droop must be 

used to share load. (An exception is a multiple engine installation in which one 

engine is operated isochronously and all other engines are operated in droop.) 

Speed Sensor 

Connect a speed-sensing device (a magnetic pickup (MPU) is normally used) to 

terminals 8 and 7. No polarity is observed. Use shielded wire and connect the shield 

only at the 2301A control. The shield must have continuity the entire distance to the 

MPU. The shield is to be insulated from all other conductors and from the MPU. 

Installation Check-Out Procedure 

When the installation is completed perform the following check-out procedure 

before beginning the start-up adjustments in Chapter 3. 

1. Visual Inspection: 

 a. Check the linkage between the actuator and the prime mover for 

looseness or binding. Refer to the appropriate actuator manual, and 

Woodward manual 25070, Electronic Control Installation Guide, for 

additional information on linkage. 

The actuator lever should be near, but not at, the minimum position 

when the fuel or steam rack is at the minimum position. This could 

avoid a dangerous condition caused by an engine which will not shut 

down. 

 b. Check for correct wiring according the plant wiring diagram. 

 c. Check for broken terminals and loose terminal screws. Make sure all 

terminal lugs are carefully and correctly installed. (Incorrectly installed 

crimp-on terminals can cause governor failure.) 

 d. Check the speed sensor (MPU) for visible damage. Check the 

clearance between the gear and the sensor, and adjust if necessary. 

See Woodward manual 82510, Magnetic Pickups and Proximity 

Switches for Electronic Controls. 

2. Check for Grounds. 

 With the power off, check for grounds by measuring the resistance between 

each terminal and the grounding bolt located below terminal 9. Terminals 1 

and 2 are power-input terminals. Either of these terminals may be grounded 

in accordance with local codes or through other equipment powered from 

the same supply. If either is grounded, a high resistance to ground will be 

evident at terminals 1 through 5 on low voltage models and terminals 1 

through 4 on high voltage models. grounds present on these terminals will 

not normally affect operation, unless they interfere with the input power or 

switching logic. Grounds on terminals 7 through 17, detected by readings 

other than infinity, should be located and removed.
