TC-4 – Tech Data

Power-Up.

The TC-4 should be plugged into a regular 110v single phase receptacle outlet, using the supplied surge protector.

When the TC-4 is plugged in, it will automatically boot to the Master Home screen. (image 1.1) There will be a green light visible on the lower left corner of the screen bezel.

During the boot sequence, the TC4 will establish its address on the network and display the IP address and the MAC Addresses for the TC-4 and its PLC in the lower left corner of the Master Home Screen. Once boot is complete, the unit should display "Running" next to a blinking green light below the network addresses.

Com Error.

If you see a red light next to the words "Com Error" below the green light, unplug and reboot the TC-4 in an attempt to reconnect with the network. If the red light reappears, this would indicate a communication error for the PLC, and a call to Seneca Service is required to have a technician replace the PLC.
