(2) Any LED indicator other than RDY and 60 Hz is lit or flashing
If any LED indicator other than the RDY and 60 Hz LED indicators (e.g. ALM or ERR LED
indicator) is lit or flashing, an alarm or error has been detected. An input circuit may be
incorrectly connected, or the self-diagnosis function may have detected an internal error.
Follow the steps below to locate the cause.
- All loops with no sensor connected should be disabled using the controller mode
registers.
- For a loop configured for thermocouple or DC voltage input, no signal connection
must be made to its NC terminals, as shown in Section A4.3.2, "Terminal Wiring
Diagram." Otherwise an AD converter error may be detected.
- Check that register preset values are appropriate. See the table below.
