Channel 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
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).
2. If an indicator lights, use the Station Setup window to determine which signal caused the indicator to light.
a) Channels indicators - display the Station Setup window, click Channels, and then click the Channel
Summary tab to display the status of each channel feedback signal.
b) Signals indicators - display the Station Setup window, and click Station Signals to display the status
of each signal.
3. If necessary, fix the condition.
Saturated Calculated Input Signals
When a calculated input used as active feedback becomes saturated, it is because one or more of the sensor
signals used to create it has become saturated.
Note:
A calculated input is derived from sensor feedback that is modified by a mathematical function.
Troubleshooting
If your system has a saturated feedback interlock check to see if the active feedback signal is a calculated
input. If it is, you must identify and resolve the saturated sensor component of the calculated input to bring
the calculated input within range.
