become blocked.

Stops shall be provided to limit the angle of movement of the

the gates shall be readily accessible for inspection, adjustment and

repair. The gate shifting ring shall be of east steel or welded plate

The actuator cabinet will be located on the generator floor,

and shall be totally enclosed. m of the necessary valves to controlthe oil for the actuating mechanism shall be of the hydraulically

operated type, incorporated as an integral part of the actuator unit and

shall be controlled by a ms.nuall;v operated pilot valve aomted on the

hydraulic control of the oil preaeure to the gate servo-motors and the

blade servo-motor shall be included. The relay valve for gate control

(and blade control) shall be of the oil pilot operated type.

All electrical control wiring within the actuator shall ter-

minate in suitable terminal blocks, located within the actuator housing

and readily accessible by steel doors in the housing. They shall be

grouped on one side or the actuator and autticient space shall be pro-

vided below these terminal blocks and within the housing to accommodate

all incoming conduit. All cmtrol wiring within the actuator shall be

color coded. It shall be neatly and properly supported and protected

from abrasion where such may occur.

The relq operated oil pilot valve shall be connected in such

sew that the operation of the overspecd trip on the main shaft will

(10) Si Drooa. A device for controlling the speed

droop oi‘ the turbine, which can be operated manually at the actuator.

The mount oi‘ speed droop shall be adjustable from sero to S percent.

The design oi’ the speed-droop control mechanism shell be such that it

will be possible to adjust it so as to secure the sost etficimt divi-

lion otloadbetlreen this turbineandthesimilar turbines tobe 'installed in the future, and between thie and interconnected poser

plants according to their individual characteristics and the load

requirements of the system.

(ll) if Switches. Five independent amdliary

switches operated from the turbine-gate notion. Each switch shall be

adjusted to close or open its contacts at any point from sero to three-

tenths gate opening, as deaired. The contacts shall be ungroundsd and

suitable for interrupting 1.5 amperes at 250 volts, direct current.

(12) Air Valve. A combination automatic ~and hand»-

operated air valve for controlling the operating of the generator brains.

The air valve shall be arranged so that the brakes cannot be applied

until the turbine gates are fully closed and the generator disocnnected

Ira the line. When operated automatically tho brake application shall

in addition be deterred until the unit speed has decreased to approxi-

mately 20 revolutions per minute. The operations of the automatic air

valve shall be initiated by means of a control switch on the actuator

be adequate for operating the valve when the solenoid for the automatic

operation is anerflsed and shall be provided with a spring-loaded, hand-

grip release to break the electrical circuit.

(13) Pressure Switch. A pressure switch with an adjustable

1.5-ampere, 250 volt, direct-current, xmgrounded contact to close an

alarm circuit when the governor oil pressure drops to a predetermined

value. Tim alarm will be furnished by the Purchaser.

(Ila) Pressure Witch. A pressure switch with m adjustable

l.5-capers, 250 volt, direct-current, ungrounded contact to open on

extruely low governor oil pressure, for use as a starting interlock.
