About Signal States
The Stations Controls panel includes indicators that show the state of groups of signals. The status of
individual signals can be viewed in the Station Setup window by clicking Channels (for active feedback
signals) or Station Signals (for all signals).
Status Indicators
The Station Controls panel includes signal status indicators.
Channel Feedback Signals - this group of indicators shows the status of any of the signals designated as
active feedback for a control channel.
Signals - this group of indicators shows the status of all the signals (for example, auxiliary inputs), including
those designated as active feedback for a control channel.
If a signal becomes saturated, the Saturated [2] indicator in the Signals group turns red. Other signal statuses
include Out of Range [1] (indicator turns yellow), Invalid [3] (indicator turns red), or Disabled [4] (indicator
turns black).
Out-of-Range Feedback
A feedback signal is out of range when it exceeds its calibrated range but is not saturated. Data taken from
out-of-range signals may not be accurate.
Saturated Feedback
A signal is saturated when it exceeds the full scale of the controller electronics making the signal value
unknown. A saturated active feedback signal lights a red station Limits indicator and sets an interlock in the
Station Manager window’s Station Controls panel.
When a saturated active feedback signal sets an interlock, station power is removed from the station. You
must then adjust the saturated signal within its operating range before you can apply and maintain power to
the station. Clicking Reset/Override overrides the interlock to allow you to apply power and use manual
command to move the actuator(s) to bring the sensor signals back into range.
