6.2 Single Display Functionality
Introduction
A UDC2300 instrument, which has been configured with a ‘0’ for software options (i.e.,
DC230x-xx-x0-xx), will only have a single display capability. 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
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 non-latching.
While a failsafe condition exists, the controller output will assume the failsafe value.
When the failsafe condition goes away, normal automatic operation continues.
