An explosion-proof housing (UL listed) is also available for use in hazardous
areas. The housing is equipped with a 24 Vdc permanent magnet motor and, as
an option, a 24 Vdc shutdown solenoid (energize-to-shutdown type only).
Low Lube Oil Pressure Shutdown
Figure 7-6 shows a low lube oil pressure shutdown. This device stops the prime
mover when engine oil pressure falls below a safe level. There is no additional
external linkage required.
For more information and parts illustration, see manual 03016.

Any failure that would cause the governor to be inoperative would
also cause the shutdown solenoid to be inoperative.
Magnetic Speed Pickup
The magnetic speed pickup monitors governor speed without having to provide
an additional drive pad on the engine. Figure 7-7 shows the assembly on a UG
governor.
For more information, see manual 36052.
