LED LIGHTS ON PWM

The PWM lower board is designed with two diagnostic LED lights. The LED’s are color coded according to their specific function.

LED 1 (red) – This indicates a high current draw similar to the C.LIM LED on our SCR lower control board. LED 1 will only light if there is high current being used due to a possible worn out treadbelt and deck system or it can also light if the IR pot is out of adjustment. The IR pot controls how the PWM board reacts to varying loads (users’ weights). If the IR pot is out of adjustment you will notice the treadbelt will surge and the red LED 1 will flash in unison with the belt surge.

LED 2 (green) – This indicates proper line voltage is being supplied to the PWM board. This line voltage is delivered to the PWM via the belt relay located on the relay board. When the belt relay energizes 110VAC or 220VAC is sent to the input terminals (L1 & L2) on the PWM board and LED 1 illuminates.
