DR4300 Circular Chart Recorder

4.3.15 Alarms Set Up Group

Introduction
If the recorder hardware supports outputs, one or both relays can be used for alarming. An alarm is an
indication that an event that you have selected during configuration (process variable, for example) has
exceeded one or more alarm limits. There are two alarms available for each pen (assuming no relay is being
used for control). Each alarm has two setpoints. There are two alarm output selections, high and low. You
can configure each setpoint to alarm either high or low. Each alarm has an adjustable hysteresis of 0.0 % to
100.0 % that is configurable for that alarm's setpoint.
If the "OUTALG" function in the control group is set to "RLYD", both relays on the printed circuit
assembly for the pen being configured are used for control, and the prompts in the alarm group will not be
displayed. If "OUTALG" is "RLY", or if the recorder is a limit controller, then Relay 1 is used for control.
In these cases only the prompts for the second alarm (Relay 2) will be displayed.
If "TIMER" is set to "ENAB", then Relay 2 is used by the timer and prompts for the second alarm will not
be displayed.
