previously existing configuration inputs will have to be re-entered if this function is executed.
A full 10-second magnet hold on PGM 1 is required to execute this function.
From the “Restore Defaults” text scroll, hold the programming magnet over PGM1 until the “▲” prompt
appears and continue to hold 10 seconds. The display will scroll “Restoring Defaults”, and then will revert to
the “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).
NOTE: The default settings on the TP-624D are not restored until power is cycled on the sensor.
Following the execution of “Restore Defaults” and a power cycle of the sensor, the TP-624D 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 back into
operation.
 Range = 100ppm. Range must be set appropriately by the operator (3.5.3).
 AutoSpan Level = 25ppm. AutoSpan level must be set appropriately by the operator (3.5.2).
 Heater Power: Heater Power settings are lost and “Set Heater Power” (3.5.4) must be performed before
“AutoSpan”.
 AutoSpan: AutoSpan Settings are lost and a successful “AutoSpan” must be performed before placing the
Sensor into operation (3.4).
 Serial ID: The Modbus address of the sensor must be set appropriately by the operator (3.5.7).
 Alarm and Fault Settings: The alarm levels and relay properties must be set appropriately by the operator
(3.5.8 and 3.5.9)
3.5.7 Set Serial ID
Detcon Model TP-624D sensors can be polled serially via RS-485 Modbus™ RTU. Refer to Section 4.0 for
details on using the Modbus™ output feature.
Set Serial ID is used to set the Modbus™ serial ID address. It is adjustable from 01 to 256 in hexadecimal
format (01-FF hex). The current serial ID can be viewed in View Sensor Status using the instruction given in
Section 3.5.1 View Sensor Status.
The menu item appears as: “Set Serial ID”.
From the “Set Serial ID” 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 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 PGM1 or PGM2 for 3-4 seconds to accept the new value. The display
will scroll “ID Saved”, and revert to “Set Serial 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 Serial ID” 5 times and then return to Normal
Operation).
