PART NAMES
This chapter describes the part names of the temperature control module.
No. Name Description
(1) RUN LED 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
(2) ERR LED Indicates the error status of the temperature control module.
On: An error has occurred.
Off: The module is operating normally.
(3) ALM LED 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.
(4) HBA LED 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.
(5) Terminal block for I/O Used for temperature sensor input and transistor output.
(6) Terminal block for CT Used for current sensor (CT) input.
(7) Terminal block cover Prevents electric shock when current is applied.
(8) Cold junction temperature
compensation resistor Used when cold junction temperature compensation is executed for the R60TCTRT2TT2 and
R60TCTRT2TT2BW.
(9) Production information marking Displays the module production information (16 digits).
