RING-PISTON 1W9460 - Caterpillar

Do the following checks on the control. Then verify the functioning of set points and adjustments.
Connect the programmer, Control View, or Watch Window to the control in accordance with the instructions in this Service Manual, "Standard Menu Items". Verify that correct voltage and polarity are applied to the control. Verify that the programmer does the self test while the programmer is powering up. Failure to do this test will indicate that there has been a failure with the control or the programmer. If failure occurs, try this step with another programmer. If the test still fails, replace the control. If the test passes with the second programmer, replace the programmer.
Verify the controller "ID" on the Control View by clicking on help then about. Verify the "ID" of the controller on the programmer by pressing the "ID" key. Verify the "ID" of the controller in Watch Window by right clicking the tab for viewing and then click on the "properties". The message "5414-514" and the revision number should appear for the "Application ID". A failure indicates either the control or the programmer has failed. If a failure occurs try this step with another programmer. If the test still fails, replace the control. If the test passes with the second programmer, replace the first programmer.
Select the "1st Dynamics Menu". Verify that all set points are still correct from installation. Repeat for the other menus. If any differences are found, change the set point(s) to the correct value. Press the "SAVE" key on the programmer or save the settings by using the Control View or the Watch Window. The programmer should display the message "Saving Changes". Remove power from the control for at least 10 seconds. Verify that the values that were retained are correct with the values before powering down. A failure will indicate that the control has failed and the control needs to be replaced.Discrete Inputs
Do the following test. This will verify the function of the discrete inputs. Do these tests when the engine is not running.
Close the "Open to Run" contact. Verify that the LED is illuminated at terminal 36 on the control. If the LED is not illuminated and the correct voltage is verified, the control has failed and the control should be replaced. Select item "H - Close to Stop" on the "Display I/O" menu. The status should be in the "TRUE" state. Open and close the contact, if the value does not change from the "TRUE" state to the "FALSE" state. If this occurs, the control has failed and the control should be replaced.
Repeat step 1 for all the discrete inputs. Verify that the terminal has the proper voltage. Verify that the proper LED is illuminated. Verify that the correct status appears in the "Display I/O" menu.Lube Oil Pressure Input
The following tests verify the function of the "Lube Oil Pressure Input". This is Signal Input 1.
Connect a power source of 4 to 20 mA or 1 to 5 VDC to terminals "42+" and "43-". For
