Reset Push Button
The controller is equipped with a reset push button. Reset via the push button is necessary under
the following conditions.
•
You forget the password to go online via the programming software.
•
You are unable to determine the IP address and SRS of the controller.
The push button is accessible through a small round hole at the top of the housing,
approximately 4…5 cm (1.6…2.0 in.) from the left rim and recessed approximately 9.5 mm
(0.375 in.).
To reset, press and hold the push button for 20 seconds while rebooting the device by cycling
power. Pressing the Reset push button during operation has no affect.
With activation of the reset button:
•
all accounts are deleted except for the default account.
•
IP Address and System ID (SRS) are set to their default values.
The next time you cycle power, these settings will be restored to the last values stored into
nonvolatile memory. This means that either the settings prior to the reset will be restored, or if
any settings were changed after the reset, those new settings will still be in effect.
IMPORTANT
Activate the reset push button using an insulated pin to prevent short-circuits.
