3.2.5 Moving The Actuator
The actuator can be moved clockwise or counterclockwise by pressing either one of two red buttons
located
on the actuator (Figure 3-9). One red button moves the actuator shaft clockwise, and the other moves
the
actuator shaft counter-clockwise. The servo will automatically stop when it reaches the end of its
travel.
Moving of actuators manually should only be done when the main fuel valve is closed. Moving the actuators
manually while the main fuel valve is open will generate a fault.
Releasing the manual pushbutton will allow the PLC to automatically command the actuators to position;
therefore the buttons should not be used during commissioning, but only as a troubleshooting tool.
