4.5.2.4 Viewing and Changing Alarm Setpoints
Introduction
If the recorder hardware supports outputs, one or both relays can be used for alarming. An alarm is an
indication that an event specified 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. During
configuration, each alarm setpoint is configured to alarm either high or low.
The alarm setpoints can be changed by the operator if the alarm parameters are not locked (see Subsection
4.3.19). If a recorder output is being used for control, that output is not available as an alarm and
the prompts will not appear.
Procedure
The procedure for displaying and changing the alarm setpoints is listed in Table 4-31.
