When the FMS-1650 is configured to use any of the secondary analog
outputs in PID mode, the constants that determine the performance
and characteristics of the closed-loop control scheme may be
specified using the corresponding option on the PID Loop Setup menu.
Selecting one of the secondary PID loops from the PID Loop Setup
menu invokes the PID Loop x Settings configuration popup as shown
in Figure 57, where the user can specify the proportional, integral, and
derivative constants to be used by the closed-loop control scheme for
the corresponding analog output.
The three dimensionless PID constants may vary from zero to 100
using the three sliders on the configuration screen. The proportional
constant is limited to 0.5 as a minimum to prevent the inadvertent
disabling of the analog output. The blue increment and decrement
buttons may be used to step each constant in increments of 0.5.
The next section discusses the options available on the Alarms Setup
menu and the configuration of the alarm resources on the FMS-1650.
