1. Connecting

1.1. Connecting to the indicator

The following describes how to connect the indicator to the load cell.

Follow the procedure below for the indicator connection.

1. Connect the load cell cable to the “LOAD CELL” terminal (Fig. 2), the indicator’s power cable to the “AC IN” terminal

(Fig. 3), both located on the rear panel of the indicator. (Refer to “3.4. Connecting Load Cell Cables” and “3.5.

Connecting Power Lines” in the instruction manual.)

2. When using the photo eye sensor, connect it to the “I/F” terminal on the rear panel of the indicator. (Refer to

“Connection of Photo eye Sensor” of “11. Interface” in the instruction manual.)

* Optional OP-02 Relay output and OP-05 parallel I/O can be installed in the indicator for a total of up to two units.

However, corresponding numbers for the DI/DO vary depending on the slot installed to.

Installing the OP-02 Relay output into optional slot 1 allows use of DO12 to DO20. Installing the OP-02 Relay output into optional slot 2 allows use of DO28 to DO36. (Refer to “11.5. OP - 02 Relay output” in the instruction manual for details.)
