Physical Symptoms-If Wire Cut
1 Purple Ground from
RPM sensor
n/a ground Normal: No speed/ rpm readings.Eng1 No rpm
readings.
2 Black Ground from
motor
n/a ground Normal: After pressing start and resistance+
motor continues to rotate upward during
pressing resistance- motor stops and does not
zero. Eng1:Motor operates but no change in
motor count.
3 Or-
ange
Zero switch
sensor
If zero switch engaged
(lowest resistance level)
+5.0vdc, open. Any other
resistance position: 0.0vdc,
short.
Normal: After pressing start and resistance+
motor continues to rotate upward during
pressing resistance- motor stops and does not
zero. Eng1: Motor operates but no change in
motor count.
4 Brown Optic count
from motor
+5.0vdc. Ifslot in optic disk
aligned with sensor, 0.0vdc
Normal: After pressing start and resistance+
motor continues to rotate upward during
pressing resistance- motor zeros itself. Eng1:
Motor operates but no change in motor count.
5 Green Power to
resistance
up
+0.0 to 0.4vdc if motor idle.
+8.5vdc if resistance
increasing. +0.6 to 2.0vdc if
resistance increasing.
Normal: After pressing start and resistance up
value is displayed and there is no motor
movement.Eng1: No motor movement and
motor count does not change.
6 White power to
resistance
down
+0.0 to 0.4vdc if motoridle.
+8.5vdc if resistance
decreasing +0.6 to 2.0vdc if
resistance increasing.
Normal: After pressing start and resistance up
value is displayed and there is no motor
movement.Eng1: No motor movement and
motor count does not change.
7 Yellow RPM sensor If magnet aligned with rpm
sensor: 0.0vdc, short. If
magnet not aligned withrpm
sensor: 5.0vdc, open.
Normal: No speed/ rpm readings.Eng1 No rpm
readings.
8 Grey Power to
console from
power sup-
ply
Dependent upon power
supply.
No power to console
9 Blue Ground from
power sup-
ply
n/a ground No power to console
10 Red Power to
DC motor
i.c.board
+5.0vdc Normal: After pressing start and resistance+
motor continues to rotate upward during
pressing resistance- motor stops, but does not
zero itself. Eng1:Motor operates but no change
in motor count.
Note: Wire colors are subject to change.
