Physical Symptoms-If Wire Cut
1 Red Incline Up 0.0 vdc before started, +1.9
vdc while inclining, 0.0 vdc
while declining. Voltage
constant while inclining/
declining.
2.5 vdc b/f start,
5.0 vdc after start.
3.7 vdc b/f start,
0.0 vdc after start.
Incline motor will go up but not down.
2 Brown Incline Down 0.0 vdc before started, 0.0
vdc while inclining, +1.9
vdc while declining. Voltage
constant while inclining/
declining.
2.5 vdc b/f start,
0.8 vdc after start.
0.0 vdc b/f start,
0.1 vdc after start.
Incline motor will go down but not up.
3 Orange GND n/a ground 0.0 vdc 0.0 vdc
Console will not turn on.
4 Yellow Power
Voltage (to
UCB)
+15 vdc constant range. 0.0 vdc 14.55 vdc Console will not turn on.
5 Green Drive Motor
Relay
+1.6 vdc before started, 0.0
vdc after started.
1.4 vdc b/f start
0.8 vdc after start
0.0 vdc b/f start
1.4 vdc after start
No belt movement.
6 Blue Stop Constantr 0.53 vdc-0.69
vdc 3.6 vdcwhen the safety
key is removed. Will remain
at 3.6 vdc untill Start is
pressed.
5.0 vdc safe off
1.3 vdc safe on
1.7 vdc running
1.9 vdc paused
16.6 vdc safe off
0.0 vdc safe on
and running
No physical symptoms were noticed when
this wire was removed.
7 Purple Incline Pot/
VREF+
+2.5 vdc at 0.0% incline,
+0.5 vdc at max incline.
Voltage changes with each
change in incline.
2.5 vdc 3.7 vdc b/f start,
5.0 vdc after start.
If the incline is changed from 0.0%, the
motor will move constant up untill the in-
cline on the console is returned to 0.0%. it
will then stop in place and NOT go down.
8 Grey Incline VCC/
ELE
+2.5 vdc constant. 3.8 vdc b/f start
4.8 vdc after start
2.5 vdc Incline constant up as soon as start is
pressed. Incline will work in Hardware
test.
9 White RPM When the speed sensor is
aligned to the magnet; short,
0.0vdc. When the speed
sensor is not aligned: open,
+5.0 vdc.
5.0 vdc 0.0 vdc Console will use default PWM value or
auto-cal values. Will not auto-cal, will not
show speed in Hardware Test.
Note: Wire colors are subject to change.
