Use this procedure in the following situations:
If an I/O module was previously configured with a different address key or a

different point database, such as a different sensor type.
You want to force the TC Modular or TC-36 to reconfigure a module.

Do the following to reset a module to the factory settings:
1. Verify that the module is supplied with 24 Vdc.
2. Remove the address key.
 The module's status LED starts dual-pulsing.
3. Insert the reset key.
 All of the module status LEDs briefly light to indicate the module has been reset.
4. Remove the reset key.
5. Cycle power to the module.
6. Reinsert the address key.
 After the reset, the modules operate with the factory default function for each I/O
point. Any previous local override settings are deleted.
NOTE:
If reusing an I/O module, reset the module to factory settings before you begin.
The plug-in module of a TX-I/O module assembly can be replaced at any time by the
same or a compatible I/O module type, even while the system is running.
1. Swivel the address key outward to switch off the load to the I/O module.
 Leave the base of the key plugged into the terminal base .
2. Remove the plug-in module from its terminal base.
3. Insert the new plug-in module.
4. Swivel the address key back into position.
 As soon as the new module starts communicating with the TC Modular or TC-36, it
is configured according to the module address and starts operation shortly
afterward.
