NOTE
Alarms have a separately programmable function that allows them to be latching or
non-latching. If the alarm is latched, then the programmable relay will also latch
until the alarm is reset.
To begin programming the User Defined Relays, highlight the relay to be programmed and press the SELECT
button. This action will bring up the List of Alarms/Faults screen. (Figure 29). Initially, the box beneath the relay
will be empty.
To attach alarms to each relay, follow the steps below under Navigating Protocol.
!
CAUTION
Navigating through screens with additional navigational selections at the bottom
of the display screen is slightly different from navigation involving only the
navigation buttons below the display screen. Specific instruction is given below.

NAVIGATING PROTOCOL
For the screen above and others like it, the normal screen navigation rules are changed. It is important to differentiate
between the selections at the bottom of the display screen (UP/DOWN/ADD/REMOVE/CLEAR/EXIT)
and the navigation buttons or arrow keys below the display screen. To scroll up the Alarm/Fault list, use the
arrow keys to highlight the UP selection at the bottom of the display screen. Next, press the SELECT navigation
button. Continue this sequence until you have positioned the proper Alarm/Fault in the active position at the top
of the list. To scroll down the list, use the arrow key to highlight the DOWN selection at the bottom of the display
screen. Next, press the SELECT navigation. Continue until the proper alarm is positioned at the top of the list.
When the selected Alarm/Fault is in the active position at the top of the list, it will be flashing. To attach this
alarm to a Programmable Relay, use the arrow keys to highlight ADD at the bottom of the display screen. Press
SELECT and your selection will now appear in the right hand box.
