【Check 7】 Checking the operation of the fan motor.
(Fig.7)
◇Checking point
If want to check the start-up of the fan motor directly,
can check by connecting the DC24V directly. (Fig.7)
5. CHECKING POINT & METHOD
Check the resistance at between terminals
brown and black.
Check the voltage at between terminals ORANGE
and BLACK.
Temperature controller is
broken

・Please be careful not to mistake the polarity
of the power supply.
・When connect with DC24V or wrong polarity,
fan motor will fail.
・Please use such as support coupler so as
not to short-circuit power.
