Chapter 4 Setup Menus 23
4.4 Alarm/Event Setpoints Setup Menu
Your instrument provides 16 alarm/event setpoints that can
monitor a wide variety of events; in turn, these events can be
programmed to trigger specific actions. This menu is used to
specify the events to be monitored by the setpoints, and actions to
be triggered by those events.
To program a setpoint (all 16 can be assigned to the relay) you
need to define up to six setup parameters: the setpoint trigger
parameter, operate and release limits, optional operate and
release delays, and the setpoint action. Tables 4-4, 4-5 and 4-6 list
the setpoint setup parameters, available triggers and setpoint
actions.
Example:
Trigger
parameter
Setpoint 1 is set to monitor the real-time
high current on phase 1 (the trigger
parameter).

The operate (On) and release (OFF)

operation are defined as 1200A and
1100A respectively.

}
Release delay

The delays before operation (On d)
and release (OFFd) are set at 5
seconds and 10 seconds respectively.
