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.
