4. UPPER DISPLAY BOARD:
The upper board is powered by DC voltage. DC voltage is supplied from the relay board. Confirm
the upper display board is getting DC voltage delivered to it. You can measure across the black and
green wires from the upper wire harness. If the display board is getting the proper DC voltage
supplied to it and it does not light, then perform a membrane bypass test for ET & CT Models (see
page 46). If it’s a PT then hit the START button manually to see if it turns on.
5. FACEPLATE:
Pro Trainer (PT) models utilize a faceplate. This part has no mechanical or electrical components
that can fail. However, if you press a key and it fails to respond check for proper display board
spacing. The faceplate is designed as a passive panel. When the user presses a key (pushes thru the
faceplate) they activate a switch mounted on the upper display board. If the display board to
faceplate distance is too great, the display board switch will not be fully activated and result in a
dead response.
6. MEMBRANE PANEL:
The membrane panel has small micro switches laminated inside that transmit the user’s commands
into treadmill functions. Enter “Diagnostic Mode” to confirm proper operation of the membrane
panel. In this test mode you will be able to check each key on the membrane panel by pressing a
key. What will happen is that you will hear an audible beep and also see a numeric code appear in
the main display window. There is a numeric code assigned to each key on the panel (except the
STOP key). For a complete list of these codes see the cart on page. If you do not hear a “BEEP” or
see the proper code appear, then the key is bad and the membrane panel must be replaced. The next
page will give you a listing of all the button feedback numbers for each machine.
