UG Dial Governor
Auxiliary Equipment
A number of optional auxiliary features and devices are available for use with the
UG Dial Governor. These devices permit the governor to perform other
secondary functions such as fuel limiting, low lube oil pressure shutdown, or
effect a shutdown through an electrical solenoid. Auxiliary equipment should be
supplied as original equipment on the governor. It Is recommended that the
customer contact Woodward if field installations are desired.
The following paragraphs provide a brief description of the auxiliary equipment
available and list the manuals where detailed information may be obtained.

Synchronizer Motor and Solenoid Shutdown

Early models of the synchronizer (speed setting) motor use an ac-dc Bodine
motor, externally mounted, and available in any of the following voltages: 12, 24,
32, 48, 64, 115, 125, 230, and 250. Late models use a PM (permanent magnet)
motor using a 115 Vac, or 24 and 32 Vdc, internally mounted.
Figure 7-1 shows a UG cover equipped with solenoid shutdown. It also shows
the synchronizer (speed setting) motor as used on the UG Dial governor.

Figure 7-1. UG Cover with Bodine Motor and Shutdown Solenoid

Two models of the shutdown solenoid are available. One provides shutdown
when energized, and the other when de-energized. Each can be equipped with
or without latch. See manual 03013 for set-up procedures and parts breakdown.
Be prepared to make an emergency shutdown when starting the
engine, turbine, or other type of prime mover, to protect against
runaway or overspeed with possible personal injury, loss of life, or
property damage.
