Once the node address has been set, the actuator may be powered up.
Actuator Node Address Table:
3.2.4 Power/ Communications LED
Each actuator has a green Power/ Communications LED. The LED can assume one of three states:
OFF - check that 24 VDC power is present. The LED is also OFF when pressing either the CCW or CW red
pushbutton.
ON Solid - power present but no commands received from PLC. ON Solid is the normal state for an actuator
not required by the PLC at the time - such as the Fuel 2 Actuator when the Fuel Selector is in the Fuel 1
position.
Rapid Flickering - actuator is responding to PLC commands and sending position data.
Figure 3-8. Modbus Actuator
Power must be cycled to the actuator before a new node address setting will be accepted by the actuator.
