Features Settings
Unless otherwise specified on the order, the controller features settings are set at the
factory to the default values. If a setting must be changed, follow the procedure on the
next page. Some settings may require a password (if the controller is set up for one).
Any indiscriminate change in these settings may affect the normal operation of the Automatic Trans-
fer Switch. This change could allow the load circuits to remain connected to an inadequate source.
