Control Panel Operation Control Panel Operation All Precis LT systems have an integral front mounted control panel for controlling the system’s switches and system attributes. The control panel can also be used for system verification and redundant control. FIG. 25 illustrates a Precis LT 8x8 control panel. Other models may vary slightly in appearance. FIG.
Control Panel Operation Control Keys Level Keys Status Key Lock Key Input Keys Output Keys Cancel Key Take Key FIG. 26 2 RU Precis LT 8x8 control panel keys Keys & Functions Status Key – places the control panel in Status mode. Lock Key – locks and unlocks the control panel (password required). Cancel Key – cancels an incomplete command and returns panel to Switch mode. Cannot undo a completed operation, i.e., an operation followed by the pressing of the Take Key.
Control Panel Operation Executing & Disconnecting Switches A switch is an active connection between an input (source) signal and one or more output (destination) devices. The signals routed in a switching operation are individual signals or groups of individual signals coming through the connectors on the rear of the enclosure. You can execute switches from the control panel using the steps below. Switching Level All switches are executed on a specific level.
Control Panel Operation Note: When executing a switch, you can select multiple outputs, but only one input. To select multiple outputs, you must select the input first (see previous section). To execute a switch selecting output (destination) first: 1. Press the Cancel Key. All the lights on the control panel turn off. The control panel is in Switch mode. 2. Press a Level Key to select a level (can be omitted when switching on the default level). The Level Key illuminates. 3.
Control Panel Operation Verifying Signal Status Signal status can be verified to confirm that a switch has executed properly or to confirm correct routing to multiple outputs (destinations) without accidently executing or disconnecting switches. The Precis LT control panel can verify both input and output signal status. Verifying an input will illuminate all outputs currently receiving the input’s signal.
Control Panel Operation Locking & Unlocking the Control Panel Locking the Precis LT control panel prohibits access to the system and can prevent accidental switching. While the panel is locked, BCS commands still work; however, they cannot be used to unlock the panel. The password is a sequence of five key presses using any combination of Input and/or Output Keys.
