Digital Inputs - Johnson Controls FRICK QUANTUM LX Operation

ACCESSING:
DESCRIPTION: This screen is used to view and set the Auxiliary Digital Input values. It is also used to custom name
each of the Auxiliary Digital channels.
This screen can be used to custom name Auxiliary Digital
channels as well as performing calibration. To change a
name:
• Locally (at the Panel) – Use the [TAB] button to
scroll down the screen to the text line that you
wish to change. Press the [^] (up arrow) button.
The screen will be replaced with an Alpha/Nu-
meric key pad entry screen. Refer to the section
entitled MISCELLANEOUS SCREENS - Alpha for
additional information on using this screen.
• Using a Web browser - Click on the box that
contains the name (at the left side of the screen),
and type a new name into the box, then click
[Submit].
Use this screen to setup an Auxiliary Digital Input to be
used to generate a warning or a shutdown whenever the
associated input is not energized (off). As an example:
If Auxiliary Input 1 is set to Shutdown When Running,
and the Delay is set to 10 seconds, then whenever
the device that is physically attached to I/O Channel
17 (Digital Board 1) becomes de-energized (turns off)
AND the unit is Running, then the delay timer will
start to count down. When the Delay times out, a
shutdown message is issued (Auxiliary Input 1 Shut-
down), and the unit will stop running.
A drop down menu box is provided for each of the eight
possible Auxiliary Inputs:
