desired ID is displayed. Hold the magnet over PGM2 for 3 to 4 seconds to accept the new value. The display
will scroll Channel Saved, and revert to Set RF Channel text scroll.
Move to another menu item by executing a momentary hold, or, return to Normal Operation via automatic
timeout of about 15 seconds (the display will scroll Set RF Channel four times and then return to Normal
Operation).
3.4.8 Set Modbus™ ID
The CXT-IR sensor can be polled serially via RS-485 Modbus™ RTU. Set Modbus™ ID is used to set the
Modbus™ serial ID address. It is adjustable from 01 to 256 in hexadecimal format (01-FF) hex.
The menu item appears as: Set Modbus™ ID.
From the Set Modbus™ ID text scroll, hold the programming magnet over PGM1 or PGM2 until the arrow
prompt appears and continue to hold the magnet in place for an additional 3 to 4 seconds (until the display
starts to scroll Set ID). The display will then switch to XX (where XX is the current ID address). Swipe the
magnet momentarily over PGM2 to increase or PGM1 to decrease the hexadecimal number until the desired
ID is displayed. Hold the magnet over PGM2 for 3 to 4 seconds to accept the new value. The display will
scroll ID Saved, and revert to Set Modbus™ ID text scroll.
Move to another menu item by executing a momentary hold, or, return to normal operation via automatic
timeout of about 15 seconds (the display will scroll Set Modbus™ ID four times and then return to normal
operation).
3.5 Fault Diagnostic/Failsafe Feature
If the ITM should incur a fault, the Global Fault bit will be set on the Modbus™ output. This can occur if the
ITM detects a problem with the sensor, detects that there is no sensor connected, if the ITM has an internal
fault, or other fault condition. The Global Fault bit will be set on the Modbus™ output until the problem is
resolved. The display will show the Fault when a magnetic programming tool is swiped across either PGM1 or
PGM2. The error codes are defined in Section 6Troubleshooting Guide.
