MCB LED Indication
Note:
Use a multi-meter to
test the power socket.
210v ~ 250v
Note:
For PCB (Upper-
board)
When we designed the lower control board (MCB) for our
treadmills we placed status lights (LEDs) on it to aid in field
diagnosis and repair. The following is an overview of what these
indicator lights mean and what can be checked with them in the
field.
Light
- When lit, this indicates that
the MCB has power applied. If this
LED is off, check connections, power switch position, fuses and
circuit breakers. If the AC light is not lit, the MCB will not
operate.
Light-
when lit, this indicates the presence of
the regulated 12-volt direct current supply
necessary for the operation of the PCB. If dim the supply voltage
may be marginal and if out not present or inadequate. If the light
is not lit, the console will not operate. If the AC light is lit and
the +12V light is not, check for shorted cabling or a defective
upper console.
