Installation Check-out Procedure
With the installation completed as described in this section, perform the following
check-out procedure before beginning the start-up adjustments in 0.
Visual Inspection
1. Check the linkage between the actuator and the prime mover for looseness
or binding. Refer to the appropriate actuator manual and to manual 25070,
Electric Governor Installation Guide
, for additional information on the linkage.
The actuator lever should be near but not at the minimum position
when the fuel or steam rack is at the minimum position. If the
actuator lever gets to its minimum position before completely
shutting off fuel or steam, the control may not be able to shut down
the prime mover, causing damage to equipment or injury or death.
2. Check for correct wiring in accordance with the plant wiring diagram, Figure
1-2.
3. Check for broken terminals and loose terminal screws.
4. Check the speed sensor for visible damage. Check the clearance of the
magnetic pickup between the gear and the sensor, and adjust if necessary.
Clearance should be between 0.25 and 1.0 mm (0.010 and 0.040 inch) at the
closest point. Make sure the gear has less than 0.5 mm (0.020 inch)
diametric runout. See manual 82510, Magnetic Pickups and Proximity
Switches for Electric Governors.
