Restoring factory
settings
If the controller appears to be operating incorrectly, or is not responding to
commands, you may need to reset or restart the controller. To perform a reset or
restart, remove the cover to expose the red restart push-button and then use one of
the following procedures.
To perform a reset or restart, locate the red restart push-button and then—in
order—use one of the following procedures.
1. A warm start is the option least disruptive to the network and should be
tried first.
2. If problems persist, then try a cold start.
3. If the problems continues, restoring the controller to factory settings may be
required.
Caution
Read all of the information in this section before proceeding!
Note
Momentarily pushing the red reset button while the controller remains
powered will have no effect on the controller.
Performing a warm start
A warm start changes the controller as follows:
◆
Restarts the controller’s Control Basic programs.
◆
Leaves object values, configuration, and programming intact.
Caution
In the unlikely event that the checksum test in RAM fails during the warm
start, the controller will automatically perform a cold start. During a cold start,
controller outputs may abruptly turn connected equipment on and off. To
prevent equipment damage, turn connected equipment off or temporarily
remove the output terminal blocks from the controller before performing a
warm start.
Do either of the following to perform a warm start:
◆
Reinitialize the controller with either BACstage or TotalControl Design Studio.
◆
Remove the power jumper for a few seconds and then replace it.
Performing a cold start
Performing a cold start changes the controller as follows:
◆
Restarts the controller programs.
◆
Returns all object states to their initial factory settings until the controller
programs update them.
◆
Leaves configuration and programming intact.
