Description
Indicates the operating status of the temperature control module.
On: The module is operating normally.
Flashing: The module is selected as a module for the online module change.
Off: 5V power off, watchdog timer error occurred, or module replacement is allowed in the process of the
online module change
Indicates the error status of the temperature control module.
On: An error has occurred.
Off: The module is operating normally.
Indicates the alarm status of the temperature control module.
On: An alert has occurred.
Flashing: The temperature process value (PV) is out of the temperature measuring range, a loop
disconnection is detected, or no temperature sensor is connected.
Off: No alert has occurred.
Indicates the heater disconnection detection status or the output off-time current error status of the
R60TCTRT2TT2BW and R60TCRT4BW.
On: The heater disconnection status or the output off-time current error is detected.
Off:
The heater disconnection or the output off-time current error is not detected.
Used for temperature sensor input and transistor output.
Used for current sensor (CT) input.
Prevents electric shock when current is applied.
Used when cold junction temperature compensation is executed for the R60TCTRT2TT2 and
R60TCTRT2TT2BW.
Displays the module production information (16 digits).
