Monitoring and Operating the Controller
4.6 Single Display Functionality
Introduction
This means that the displayed value of PV, Setpoint, Setpoint2, Remote Setpoint, Input 2, Output, Bias, Aux Out, and Deviation will appear on the top display and a prompt identifying the value will appear on the bottom display.
Access the Values
Pressing the LOWER DISPLAY key will cycle through all applicable values (configuration dependent). One minute after the last press of the display key, the display will revert back to a configured default display. The default display is configured in the Input 1 Setup Group, and has three selections:
•Active Setpoint (SP)
•Process Variable (PR Y)
•Process Variable with no bottom display prompt (PR n).
Exceptions
There are three exceptions to the above rules. The displays for PID SET, Timer and Setpoint Ramp will appear the same as on a dual display model and, when displaying Timer or Ramp values, the default display switchover feature is disabled.
Auto-only Mode
The single display model is Auto only mode. The Auto/Manual key has no effect on controller mode. As a result of this, the failsafe mode is always
While a failsafe condition exists, the controller output will assume the failsafe value. When the failsafe condition goes away, normal automatic operation continues.
