※
1. The input cable (P3 cord) of the overflow sensor is connected to the terminal block [in2
Input].
※
2.
When the overflow sensor is not connected, set as “Parameter No. 07=Lo.”
※
3. The power outlet of the Controller is of 24VDC, 160mA. Watch out for the total
consumption current of the overflow sensor, solenoid valve, etc. to ensure that it will not
exceed the power outlet capacity.
5) External signal [in1 Input] connection
Connect the external signal to operate/stop the feeder in addition to the overflow sensor.
When the external signal is used, set parameter
as “Parameter No. 06 =
h
i.”
※
1. To connect the external signal, the operation panel should be removed.
Confirm that the power supply is in the OFF status. Then, detach the operation panel.
After the connection is completed, attach the operation panel, and then turn ON the power
supply.
The operation panel is connected to the main unit of the controller with a connecting wire.
When attaching/detaching the operation panel, carefully watch out for disconnection or
pinching.
To operate the start/stop of the controller according to external control signal, either method
of non-voltage contact signal or voltage signal (24VDC) can be used.
Make connection to the external control terminal block by using the method

while watching out for the signal to be used and the connection method. When wiring, be careful
not to make mistake about the polarity.
The current of 24VDC and 10mA or less flows between [+S] and [-S]. Carefully select the
connection device (e.g., minute current relay).
