Conducting a membrane bypass test can also test the functionality of a membrane panel.
Membrane Panel Bypass Test
When a treadmill with a membrane experiences a loss in power to the upper display, such as when a
customer presses the START button and nothing happens, a possible cause of this is a bad membrane
panel. A membrane panel bypass test can verify this. A membrane panel bypass test is conducted by
literally taking the membrane and bypassing its functions. The membrane panel has small micro switches
laminated inside that transmit the user’s commands into treadmill functions. These functions can be
simulated by means of a membrane bypass:
1. Disconnect the silver foil ribbon cable from the membrane panel.
2. Remove the membrane panel completely from the upper display board.
3. Use a
DRY
towel or a terry-cloth to wrap over the open area of the control panel frame. Place the
upper display board with wire harness still attached on top of the towel to prevent it from touching any
metal.
4. Look at the pins where the silver membrane ribbon cable connected to the display board. You should
note that printed on the green circuit board behind each pin is it’s specific function.
5. Using a jumper (i.e. a jumper wire with two copper ends, a paper clip, or a voltmeter set to continuity)
bypass the start button by touching one end of the jumper to the pin labeled
GND
or
GROUND
, and the
other end of the jumper to the pin labeled
START
or
ON
. (Note on page 2 where to locate these pins
on various Landice display boards) If the membrane is bad the treadmill will turn on and read
“SAFE.”
6. If it is necessary, replace the damaged membrane panel.
