Outputs - Johnson Controls FRICK QUANTUM HD Operation

ACCESSING:
DESCRIPTION: This screen is used to calibrate individual
analog outputs. NOTE: All analog outputs are calibrated at
the factory. The following can be used to confi rm or verify
this calibration.
Use this screen if an analog output signal (channel) re-
quires calibration.
The Quantum's analog outputs have a range of approxi-
mately 0 to 25mA, but most devices that are controlled by
the Quantum™ HD require a signal that varies between
4 and 20mA. To restrict the analog outputs to the proper
values, each of the outputs must be calibrated before they
can be used. Every output channel has a Low End and
a High End value that are used for calibration. Both val-
ues can be set from 0% to 100%. The output channel's
maximum value is represented by 100% and its minimum
value is represented by 0%. To calibrate the channel, the
High End percentage is decreased until the maximum out-
put for the channel is limited to 20mA. Also, the Low End
percentage is increased until the minimum output for the
channel is 4mA.
The following fi elds are provided on this screen:

Output Percentage For Selected Output - This
shows the percent of output signal value that is
currently being output for this channel.
Low End Percentage Calibrated - The percent-
age shown here represents the low (or bottom)
end of the calibration value.
High End Percentage Calibrated- The percent-
age shown here represents the high (or upper)
end of the calibration value.

Calibrate Low End - Select this button to set
the Low End calibration value, then select the
following buttons to achieve the desired setting:
• 10 - The Low End value will increase by
10% each time this button is selected.
