Diagnosis

Overview

The LED panel is used to indicate the basic module status, the state of 16-channel discrete input, and the state of the time code synchronization.

The 4 LEDs RUN, ERR, I/O, and T are on the top of the panel.

LED Indicators

The following figure shows the LED indicators of the BMXERT1604T/H module.

The 00...15 LED indicate the input states of 16-channel discrete input. The T LED indicates the status of time code input. The T LED and the RUN LED indicate the downloading state during the firmware downloading phase.

Description of Indication Pattern

The following table describes the LED indicators:

RUN	ERR	IO	T	00...15	Meaning
OFF					The module is not receiving power or inoperable
OFF	ON	OFF			The module is not operational
OFF	BLK	OFF	OFF		The module is not configured or is configuring its channels
ON	BLK	OFF	X		Module has lost communication with CPU
ON	OFF	ON	X	BLK	Field power supply interruption
BLK	OFF	OFF	BLK	X	Downloading firmware
ON	X	X	OFF	X	No external time code input
ON	X	X	FLK	X	External time code is temporarily unstable but internal time quality is acceptable
ON	X	X	ON	X	Module clock synchronized with external time code
ON	OFF	OFF	X	ON	The logical input 1 present on the corresponding channel
ON: LED is on. OFF: LED is off. FLK: The LED is on faster flashing (flickering). BLK: The LED is slower flashing (blinking). X: Do not care.
