Operating modes

After being switched on, the TC-Plug carries out a self-test, and checks all

the functions of its components. If there is a fault, the TC-Plug enters the

"STOP" mode, but otherwise goes into the "fieldbus start" state.

Status display LEDs

The module has two groups of LEDs for the display of status. The upper

group contains three LEDs and indicates the state of the PROFIBUS, while

the lower group indicates the states of the thermocouple inputs.

RUN LED The “RUN” LED is illuminated cyclically by process data exchange over the

fieldbus.

BF LED The “BF" LED indicates any fieldbus errors.

ERR LED The “ERR" LED indicates the error code of any fieldbus error.

TC RUN The “TC RUN” LED is illuminated cyclically by process data exchange.

TC ERR The “TC ERR” LED indicates the error code for the thermocouple inputs.

Local errors The bottom two LEDs are used to indicate the operating status of the

thermocouple inputs. The green LED lights up in order to indicate fault-free

operation. The red LED blinks with two different frequencies in order to

indicate an error. The error is encoded in the blinks as follows:

Fast blinking

Start of the error code

First slow sequence

Error code
