4.5 Operation of Recorder with Display and Keypad
4.5.1 Monitoring Your Recorder
4.5.1.1 Overview
Introduction
In addition to the historical chart record, you can monitor the recorder’s indicators and displays to see real
time values of inputs. If control is enabled, then setpoint, output, and deviation values can also be displayed.
Set up values can also be viewed. Depending on the lockout status, configuration values may also be
changed.
As a background task the recorder runs self-diagnostics on the printed circuit assemblies for the pens as
described in Section 8 – Troubleshooting and Pen Alignment of Recorder with Display. If a test is failed,
an error message will be displayed as described in Subsection 4.5.1.4. Depending on the recorder’s
configuration, a “failsafe” output value may be used for control in case of malfunction, as described in
Section 8.
4.5.1.2 Operator interface
Display
The indicators and displays on the operator interface let you see what is happening to your process and how
the recorder is responding. Figure 4-7 is a view of the operator interface. A description of the displays and
indicators is included.
