Alarm signal connection
The motor cooler is equipped with a stall alarm output function (electronic
alarm type). An alarm signal (H level) is output when the fan stops while
operating. Connection example is shown below. GND is common.

Note
The alarm output signal momentarily becomes H level
when starting the motor cooler since the stall alarm circuit
is not equipped with an alarm delay-start function.
Therefore, an external delay circuit is required to prevent
alarm detection when starting. The delay time should be at
least 1 second.
Overheat protection
The motor cooler is equipped with a built-in overheat protection circuit.
When a locked condition of the fan blades is detected, this function
automatically controls the current flow to the motor cooler, thus preventing it
from overheating. The motor cooler resumes operation automatically as soon
as it is released from the locked condition. Be sure to turn off the power
before making an inspection.
Note
The built-in overheat protection circuit will not prevent the
cooled motor from overheating.
