The FAC 4911 controllers ship with a default state that can assist in validating the wiring of the input and output terminals before downloading an application file. When the controller is powered on in this state, the Fault LED will flash in a pattern of two quick blinks and then a long pause (see LED status and description table).

To make use of this feature, ensure the rotary switches are set to the chosen controller number and wire the input and output terminals. Apply power to the FAC controller and connect to the device with either a MAP Gateway, a DLK0350 Local Display, or DIS1710 Local Display to view the points in the controller. The FAC controller will report an Operational status even though there is no true application loaded. CCT will not be able to commission or upload the device as a result until a true application is downloaded. The application name displayed will be the controller number followed by the model of the controller and “Default State”.

For example, a FAC 4911 controller whose rotary switches are set to 8 would have the default state application name of “8-FAC 4911 Default State”.

The default state creates I/O points for all connections on the input and output terminals. It assumes all Universal Inputs (UIs) are Nickel temperature sensors. All Configurable Outputs (COs) are treated as Binary Outputs (BOs) with an initial value of 0. The default state also takes input from a Network Sensor at address 199. If there is no connected Network Sensor, the startup of this default state will be delayed by 30 seconds as the controller attempts to establish connection with the sensor.
