Manual 26659 ProAct P-Series FL Position Controller
Woodward 19
Active Closed: (default)
Active closed can be used for situations where it is safer to make the function
inactive if the wire is broken or disconnected.
Active Open:
Active open contact can be used for situations where it is safer to make the
function active if the wire is broken or disconnected.
The fuse shown in the diagram can be the same fuse that is used for the power
supply of the actuator—there is no need for an additional fuse.
Run Input
The Run Input is a configurable discrete input that causes the actuator to run
normally when active and will force the actuator current to zero (actuator goes
limp) when not active. The low power mode provides for minimal power
consumption of the device.
The Run Input can be configured as ‘Not Used’, which sets the software to
always run. With a ‘Not Used’ configuration, the Run Input wiring is not needed. If
configured for use, the Run Input must be active to run the actuator.
CAN ID Inputs
The CAN ID inputs are used to select which CAN identifiers will be used on the
CANbus. With no programming tools, the customer can select from the four pre-
programmed CAN IDs through a hard-wired code in the engine harness. This is
especially important where more than one ProAct P-Series FL is used on an
engine. If one ProAct P-Series FL actuator is replaced with another, the new
actuator will read the correct ID number from the engine harness connector upon
power-up.
Up to four ProAct P-Series FL actuators with the same configuration can be on the
same CANbus, however, each must have a different device address. The CAN
device source address is determined by using the CAN ID HI and LO discrete inputs
upon power-up of the actuator (see Table 2-1). The TRUE/FALSE state is based on
the actuator’s configuration settings (see Table 2-2).

The CAN address high and low discrete inputs must be wired prior to
power-up to be registered.
