Cybex International LT-14464-4 Rev H, 710T manual Measure Motor Voltage at Max Speed, No Load

Cybex 710T Treadmill Owner’s Manual

displayed should not exceed 10.9 for a 115V unit, and 9.1 for a 220V unit. With a user of any weight, the current should not exceed 17.9 for a 115V unit and

15.4for a 220V unit. If higher current values are shown, the next higher mileage service interval should be performed.

Measure Motor Voltage at Max Speed, No Load

A qualified Cybex service technician should perform this test. It involves opening up the front cover, gaining access to the electronic control board, and measuring the voltage on the motor leads. Measure this at 10 mph (16 km/h) with nobody on the treadmill. The measured voltage is an indication of the health of the motor. Motor voltage should not be below 83 volts DC for the 115V unit and 168 volts for the 220V unit. If below these minimums, the motor must be replaced.

Tools Required

•Phillips head screwdriver

•Flat head screwdriver

•3/16" Allen wrench

•Voltage meter

1.Measure current draw.

A.Stand on the side rails and press the START/ENTER key and enter Manual Mode.

B.Enter Diagnostic Test Mode, by pressing and holding SHIFT, then press -.

C.Press START to scroll to d3. Press SHIFT if you need to scroll backward.

D.With the belt moving at 1 mph (1.6 kph), you will see a number displayed which represents motor current in DC current.

E.Without standing on the belt, press the + key to bring the speed of the treadmill up to 3 mph (4.8 kph). At 3 mph (4.8 kph) average current draw should be between 2.00 and 3.00 without anyone on the running belt.

F.Now, have a user walk on the belt at 3 mph (4.8 kph). The maximum current draw with a 160 lb. user should not exceed 17.9 for a 115V unit and 15.4 for a 220V. Even with a heavier user, the current should not be more than 15.4/17.9 respectively.

G.Press STOP to exit Test Mode.

2.Turn the power off.

A.Turn the main power switch in the front panel to the off (O) position.

B.Unplug the treadmill from the power outlet.
