Speed Sensor Fault Isolation – FVX, TMX No Control
1. Verify sensor is connected at FG302, J2; connect if necessary.
2. Verify speed sensor distance is no greater than1/8” from magnet; adjust as necessary
3. Stop run belt, measure DC voltage at FG302, J2, pin 1 to pin 2. Move belt motor flywheel
slowly by hand and verify voltage drop of 5 VDC as magnet passes sensor. If voltage is not
observed, replace speed sensor.
Perform Incorrect Belt Speed Fault Isolation
1. Determine if the speed unit required by stress system, mph or Km/h
2. Use belt rpm table to determine if the running belt speed is correct.
3. Verify correct settings at Leeson Speedmaster, use Leeson Speedmaster
4. Perform speed calibration to change speed units or calibrate belt circuit as required.
5. If treadmill will not calibrate or change speed, measure DC voltage input to Leeson
Speedmaster pin 5 (PWM) to pin 2 (DC GND). Voltage should vary from 0 VDC at minimum
speed to approximately 7.4 VDC at maximum speed.
6. If voltage does not vary, measure the voltage at FG 302 motor control output J3 pin 2
(PWM) and 5 (DC GND). Voltage should vary from 0 VDC at minimum speed to
approximately 7.4 VDC at maximum speed. Repair and or replace inverter cable as
necessary.
7. if voltage is not present at FG302, J3, replace FG 302 PCB
Speed Sensor Fault Isolation – FVX__C or FVX__CP, TMX__C or TMX__CP
1. Verify sensor is connected at FG309, J2; connect if necessary.
2. Verify speed sensor distance is no greater than1/8” from magnet; adjust as necessary
3. Stop run belt, measure DC voltage at FG309, J2, pin 1 to pin 2. Move belt motor flywheel
slowly by hand and verify voltage drop of 5 VDC as magnet passes sensor. If voltage is not
observed, replace speed sensor.
Interior interface Cable Fault isolation – FVX, TMX No Control
1. Turn treadmill power switch to the off position (0)
2. Unplug treadmill power cord from wall receptacle
3. Use Ohm Meter to verify continuity from FG302 U6 to Treadmill 9 pin input; repair and or
replace cable as necessary.
