Selecting one of the secondary analog outputs from the Analog
Outputs Setup menu invokes the Select AO-x Settings configuration
popup as shown in Figure 52. The user may select the operating
mode for this analog output resource (direct or PID), as well as the
signal range for this control output. The selection between voltage and
current mode for the analog output is accomplished using the hardware
configuration dipswitch on the controller module. See the FMS-1650
Wiring and Installation Guide for complete details on configuring the
analog output hardware resources.
Once the operating mode and output range have been specified,
clicking the Next button invokes the Set Upper Limit and Set Lower
Limit configuration screen. The user may specify both an upper and
lower limit above and below which the analog output will not exceed,
respectively. This feature is useful for those applications requiring
a minimum output at the control signal for an air flow damper, for
example.
Clicking the Next button invokes the final Select AO-x Settings
configuration popup where the user may remap the analog output to
one of the other analog inputs and change the action mode for the
control output.
For example, if analog output 2 is being used in a temperature control
application which receives the temperature signal via thermistor input
2, TI-2 should be selected in the Select Input Channel section of the
configuration popup as shown in Figure 51.
Figure 52. Each of
the three secondary
analog outputs may
be independently
configured for direct
or PID analog output
mode, depending
on the application
requirements.
Figure 51. For a
temperature control
application that
measures temperature
using thermistor input
2 and analog output 2
in PID control mode,
the settings would be
configured as shown
above.
