Service Menus
To access the Service menus, press the
T
key at the master screen (“
WOODWARD GOVERNOR,
721 DIGITAL CONTROL
”). To move between menus, and to move through set points within
menus, follow the instructions as for the Configure menus. Also to return to the menu
header, or to leave Service, follow the Configure instructions.
Adjusting Set Points
To adjust a set point, use the “Turtle Up” or the “Rabbit Up” keys to increase the value, and
the “Turtle Down” or “Rabbit Down” keys to decrease the value. The “Rabbit Up” and “Rabbit
Down” keys will make the rate of change faster than the “Turtle Up” and “Turtle Down”
keys. This is useful during initial set
- up where a value may need to be changed significantly.
Where necessary, to select TRUE, use either the “Turtle Up” or the “Rabbit Up” keys, and to
select FALSE, use the “Turtle Down” or “Rabbit Down” keys.
To obtain an exact value, press the = key. Key in the required figure and press ENTER.
NOTE
This may be done only if the figure is within 10% of the existing value.
To save set points at any time, use the SAVE key. This will transfer all new set point values
into the EEPROM memory. The EEPROM retains all set points when power is removed from
the control.
CAUTION
To prevent possible damage to the engine resulting from improper control
settings, make sure you save the set points before removing power from
the control. Failure to save the set points before removing power from the
control causes them to revert to the previously saved settings.
