6.8 Setpoint Program Event Set Up Group
Introduction
Segment events are used to activate relays by means of alarms. There are six alarms and six corresponding
relays. Alarm 1 controls Relay 1, Alarm 2 controls Relay 2, etc. When the setpoint program reaches the
segment, the segment event triggers the alarm which triggers the relay. The relay stays on for the duration
of the segment. There are no alarm conditions to be satisfied, that is, when the event goes on the alarm
goes on.
How to trigger a relay with a segment event
1. Program the segment event with the alarm corresponding with the desired relay.
2. Program that alarm as type EVENT. It is not necessary to program any alarm parameters other than the
alarm type.
Do not program other functions that have higher priority control of the relay. See During alarm conditions
an alarm will deenergize its associated relay unless a higher priority function has been configured for that
relay. See Table 3-11. If you want the alarm to control the relay, do not configure a higher priority
function.
3. Table 3-11.

Example of how a segment event works
For example, to have Segment 1 energize Relay 1:
Program SEG1 EV as ALARM1.
Program A1S1TYPE or A1S2TYPE as EVENT.
Do not program the Timer function Relay 1; namely, Timer.
For alarm programming information, see section 4.10.
