Voltage Checks - Horizon Fitness EX-22 Service Manual

C o nso le C a bl e Voltage Check
(All Mo dels Ex cept 1. 2E)
Note 1: All voltages measured loaded, with functioning console and resistance motor.
Note 2: All grounds same point once plugged into console with or without power on.
Note 3: If measured White (+) to Green (-) when resistance increasing = -7.7vdc, if decreasing = +7.7 vdc.
The new style servo motor voltage measurements are: (Ex22-Ex44/CSE3.5 & 4.5/EG5)
Orange =3.0 vdc if resistance at lowest,0.2 vdc if resistance at any position other than lowest.
Brown +3.0 vdc if optic sensor open. 0.2 vdc as wheel passes through optic sensor.
The above measurements for the Orange and Brown wires were using the ori-
gional serve motor. (2.2E, 3.2E, 4.2E)
