Woodward 131
Control Test and Calibration
General
Do the following checks on the 2301E control. Then verify the functioning of set
points and adjustments.
1. Connect a computer to the communication port. Start the Control Assistant
Software or the 2301E Toolkit Service Tool in accordance with the
instructions in Chapter 4. Verify that correct voltage and polarity are applied
to the control.
2. Select the 1st Dynamics Menu. Verify that all set points are as recorded
during installation. Repeat for the other menus. If any differences are found,
change the set point(s) to the correct value. Click the “SAVE VALUES” icon
on the Tool bar. Remove power from the control for at least 10 seconds.
Verify correct values were retained during power down. Failure indicates the
control has failed and should be replaced.
Discrete Inputs
Do the following test to verify the function of the discrete inputs. Do NOT do this
test with the engine running.
1) Repeat this step for all discrete inputs. Close the appropriate input. The
status in DISPLAY DIGITAL I/O should switch from OPEN to CLOSED. If the
value does not change when the contact is closed, the control has failed and
should be replaced.
Discrete Outputs
To Verify operation of the Discrete Outputs, go to the Service: S**RELAY AND
ANOUT TESTS** menu. With the engine shut down, enable the manual driver
test. From this menu, each discrete output may be activated and its operation
verified. If the output is activated, the same voltage as applied at terminal 42 and
43 should be measured between terminal 42 and the appropriate output terminal
(44
–47). Testing of the internal CB Aux relay may be done by observing the
green LED near terminal 9 and 10. The manual relay test must be disabled
(status “test off”) or the control will hold the actuator current to minimum.
