Controlling the Product Using Contact Signals
●
LIN OVERHEAT (overheat alarm)
This status signal is transmitted when the product’s internal overheat protection function is
activated. It is used to control external devices.
• REMOTE/LOCAL: This status signal indicates that the product is operating in remote
mode.
Example of contact signal control
The figure below shows a connection example for contact signal control. Isolate the contact
signal control circuit from the internal circuit of this product with a photocoupler. The coil cur-
rent of this product’s impedance selection relay is 100 mA or less.
Example of a contact signal control device (reference)
To perform contact signal control, we recommend that you use the DIO-0808LY-USB Isolated
Digital I/O Terminal for USB2.0 (hereafter abbreviated as DIO) made by CONTEC. The DIO
connectors CN1 and CN2 are used for this purpose.
Connect the product’s CONTROL INPUT terminal to CN1 and the STATUS OUTPUT terminal
to CN2. Connect the interface connector to a PC’s USB port.
For details on the DIO connectors, see the Isolated Digital I/O Terminal for USB2.0 DIO-
0808LY-USB User’s Guide.
• If the PCR CONTROL terminal is connected properly to the AC power supplies, the AC
power supply output will be turned off when the overheat protection of this product is acti-
vated.
