Detcon CXT-DM - Manual (Page 29)

Model CXT-DM
NOTE: Restoring factory defaults should only be used when absolutely necessary. All previously
existing configuration inputs will have to be re-entered if this function is executed. A full 10-second
magnet hold on PGM 2 is required to execute this function.
From the “Restore Defaults” text scroll, hold the programming magnet over PGM2 until the “
” prompt
appears and continue to hold for 3-4 seconds. The display will scroll “Defaults Restored”, and revert to
“Restore Defaults” 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 “Restore Defaults” 4 times and then return to Normal
Operation).
Following the execution of “Restore Defaults”, the CXT-DM will revert to its factory default settings. The
default settings are:
NOTE: The following must be performed in order before the sensor can be placed in operation.
• RF Channel = 4. The RF Channel should be set appropriately by the operator (Section 3.4.6).
• Modbus ID = 01. The Modbus ID must be set appropriately by the operator (Section 3.4.7).
• AutoSpan Level = 50% of range. AutoSpan level must be set appropriately by the operator (Section
3.4.3).
• Range: Defaults to range of intelligent plug-in sensor, must be set to the appropriate level by the operator
(Section 3.4.2).
• AutoZero: AutoZero Settings are lost and user must perform new AutoZero (Section 3.3.1).
• AutoSpan: AutoSpan Settings are lost and user must perform new AutoSpan (Section 3.3.2).
3.4.6 Set RF Channel
Set RF Channel is used to set the RF Channel used for communication. There are 16 possible RF channels.
All of the sensors must be on the same RF Channel for the network to operate properly. The RF Channel is
settable from 0 to 15. The current RF Channel can be viewed in View Sensor Status.
The menu item appears as: “Set RF Channel”.
From the “Set RF Channel” text scroll, hold the programming magnet over PGM1 or PGM2 until the “
”
prompt appears and continue to hold the magnet in place for an additional 3-4 seconds (until the display starts
to scroll “Set Channel”). The display will then switch to “XX“ (where XX is the current RF Channel). 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 3-4 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” 5 times and then return to Normal
Operation).
3.4.7 Set Modbus ID
Detcon CXT sensor can be polled serially via Modbus™ RTU. Refer to Section 4.0 for details on using the
Modbus™ output feature.
Set Modbus ID is used to set the Modbus™ address of the unit. It is adjustable from 01 to 256 in
hexadecimal format (01-FF hex). Each sensor must have a unique Modbus address to operate correctly on the
network. The current serial ID can be viewed in View Sensor Status.
