Control unit assy assembly   (55)   are   mounted   with   brackets attached  with  heat  sink  (57)  onto  mounting plate (78). (5)  Reactor  assembly  (46)  is  mounted directly to mounting plate (78). Section III.  GOVERNOR CONTROLLER 4-11.    GENERAL.    The  governor  controller  A106  (56, figure  4-1)  is  the  electronic  portion  of  the  load  sharing and   speed   control   unit   which   is   part   of   the   electric hydraulic governing system. The governor controller has two major functions, speed control and load sharing.  It measures   engine   speed   via   a   magnetic   pickup   and compares   it   to   a   speed   reference.      It   then   feeds corrections  to  the  hydraulic  actuator  governor  on  the engine.  It also has a speed sensing fail safe circuit, and a    time    ramp    circuit    (deceleration    to    idle    speed    - acceleration to rated speed). 4-12.    INSPECTION.    Inspect  the  governor  controller front panel by removing the access cover (7, figure 4-1), paragraph   4-2.      Inspect   the   connections   on   terminal boards  for  loose  wires,  inspect  the  potentiometers  for signs  of  damage,  and  the  control  panel  for  scratches, dents or other damage. 4-13.        ADJUSTMENTS.        The    controller    has    eight adjustment controls located on the front cover.  Perform the following adjustments whenever the unit is replaced. NOTE Do  not  adjust  the  DE-DROOP,  RAMP TIME, and LOW IDLE SPEED adjustments  on  the  unit.    These  pots are factory set on each controller. a. Disconnect   F-   and   F+   leads   on   voltage regulator. b. Set   RATED   SPEED   (10T)   potentiometer fully  counterclockwise,  then  rotate  4  turns clockwise. c. Set   the   STABILITY,   GAIN,   LOAD   GAIN, and   DROOP   potentiometer   to   mid-range positions. d. Toggle the FREQUENCY SELECTOR switch  on  the  AC-DC  Control  Panel  to  the 50 Hz position. e. Start the generator set. f. Adjust the RATED SPEED (10T) potentiometer  to  obtain  50  Hz.  Monitor  the FREQUENCY meter on the Control Cubicle. g. Toggle the FREQUENCY SELECTOR 4-9
