Model 10C
4.5 Modbus™ Set
Set Modbus™ provides a means to set the unique identifying Modbus™ Address. The Address is also known
as the “ID” or “Modbus RTU ID”.
The menu item appears as: “MODBUS SET”.
From the “MODBUS SET” display press the “ENT” pushbutton to enter the function.
To enter “ID Set” function, press the “ENT” pushbutton while the “ID Set” display is scrolling. The display
will flash the current Modbus™ ID Address in Hexadecimal format. Use the “×” and “Ø” pushbuttons to set
the appropriate address and press the “ENT” pushbutton to accept this value. The display will stop flashing
and the ID address will be displayed continuously. Press the “ENT” pushbutton again to leave the menu item.
The display will return to “MODBUS SET”.
The “×” and “Ø” pushbuttons can be used to move to another menu item, or the “ESC” pushbutton can be
used to leave Program Mode.
NOTE: Pushbutton inactivity during any part of the above procedure will eventually cause the
displayed function to time out and return the display to Normal Operation.
4.6 Sensor-Cal Mode
Sensor Cal Mode is used to set the 10C Controller’s output current to 2mA and to inhibit alarm processing
temporarily during a field calibration of the sensor.
The menu item appears as: “SENSOR-CAL MODE”.
From the “SENSOR-CAL MODE” display, the “ENT” pushbutton is used to enter the function. The display
will flash and show “Cal-Mode OFF”. The “ENT” pushbutton is used to change the state to “Cal-Mode ON”
or the “ESC” pushbutton can be used to escape to the menu.
When the 10C Controller is set to “Cal-Mode ON”, the Current Output will change to and remain at 2mA and
input current will not be processed for alarm triggering. The purpose of this is to allow the sensor’s output
current signal to be ignored while calibrating the sensor.
Until the controller is returned to normal operation by pressing the “ESC” pushbutton or when the 10C
Controller reaches a time limit. To help remind the user that the 10C Controller is in Sensor Calibration Mode,
the Fault LED will flash on/off rapidly and continuously while the display scrolls the text “Cal-Mode ON”.
To escape this function, the “ESC” pushbutton can be pressed and the Sensor-Cal Mode will be turned off and
the 10C Controller will leave the Program Mode and return to Normal Mode.
NOTE: The Sensor-Cal Mode will eventually time-out and return the controller to Normal
Operation if escape of the function is not manually executed. The timeout period is nominally
one hour.
