DR4300 Circular Chart Recorder
74 DR4300 Circular Chart Recorder Product Manual 12/03
Key Function
• Increases the setpoint, output, or configuration values displayed. ***
• Decreases the setpoint, output, or configuration values displayed. ***
*The second setpoint is available if one of the digital inputs is configured to use this alternate setpoint in
case an external event triggers the “remote switch”, or if Control group parameter NUMSPs = TWO.
**Displayed only when a setpoint program is being executed. REC cycles remaining will be displayed
only if the program was set to run more than 1 cycle, and if the program is not executing the last of
multiple cycles. See Appendix C for detailed instructions for executing a setpoint program.
***If the timer is enabled (TIMER = ENAB) and Timer group parameter START = KEY, then this key
can be used to start the timer. To stop the timer before its timeout period has expired, set TIMER = DIS.
Once the timer has expired, use the Increment or Decrement key to reset the timer. Relay 2, which was
energized when the timer expired, will be de-energized when the timer is reset.
4.3 Configuration (Recording and Output Set Up)
4.3.1 Overview
Introduction
The display and keypad on the DR4311, DR431, DR4331, and DR4332 models are used for setting up
recording and output options in Set Up (configuration) mode, as well as for displaying real-time values
during normal operation. (Instructions for using the user interface are in Subsection 4.2.)
When the recorder is in configuration mode, setup parameters are displayed, grouped by function.
Designate site-specific values by selecting them from a list of choices, or entering them as numeric values.
If your recorder is equipped with two pens, function parameters are configured separately for each pen, and
stored on the printed circuit assembly (PCA) associated with that pen. The PCA on the right (when facing
recorder) is for pen 1 (purple); the PCA on the left is for pen 2 (red).
If the hardware supports optional relay outputs for each pen, parameters are available for configuring
control and/or alarms using these outputs. If an optional relay is used, then it can be wired for Normally
Open and Normally Closed action.
Hardware switches must be set to match the input type, and to specify input state in case of input failure.
