5.3 Function
5.3.1 Disconnection detection function
Thermocouple input module has a function to detect the disconnection and display it.
That the module detects and displays disconnection means that the following cabling path would have
partially bad connection, which requires taking measures
(1) Disconnection occurs between a sensor used/compensating cable and module, LED(ALM) flickers
every second and generates error code.
(2) Disconnection can be detected by channels. However, it is available for the only channel(s)
designated for operation. LED (ALM) is commonly used for every channel. It flickers in case even
only one channel is disconnected.
