INSTALLATION CHECKOUT
Carefully complete the following checkout procedure before operating the
hydraulic system. If you find a problem during the checkout, refer to the diag-
nostics and troubleshooting section (Section 5) for further information.
e installation checkout is typically conducted with the handheld pro-
grammer. Otherwise, if you have connected an external Status LED to Pin
J1-6, you can observe this LED for fault codes; the codes are listed in Section 5.
Before starting the procedure, check that the hydraulic hoses are secure,
and the system primed with oil.
Drive the vehicle to a location that will provide enough
room for all the hydraulic functions to be tested; if indoors,
be sure the ceiling height is adequate.
Do not stand, or allow anyone else to stand, directly in front
of or beside the vehicle during the checkout.
Make sure the keyswitch is o, the throttles are in neutral,
and all the hydraulic system switches (Lift, Lower, Reach,
Tilt, Shift, Rotate, etc.) are open.
Wear safety glasses and use well-insulated tools.
1. If a programmer is available, connect it to the programmer connector.
2. Turn the keyswitch on. e controller should power up, the program-
mer should present an initial display, and the Status LED should begin
blinking a single ash.
If not, check for continuity in the keyswitch circuit and controller
ground.
3. If you are using a programmer, scroll to the Faults Menu. e display
should indicate “No Known Faults.” Close the interlock switch (if one
is used in your application). e Status LED should continue blinking
a single ash and the programmer should continue to indicate no faults.
If there is a problem, the LED will flash a fault code and the pro-
grammer will display a fault message. If you are conducting the checkout
without a programmer, look up the LED fault code in Section 5.
When the problem has been corrected, it may be necessary to cycle
the keyswitch in order to clear the fault.
4. If you are using a programmer, scroll to the Monitor Menu. Scroll down
to observe the status of the interlock and four speed select switches
