ALARMS FUNCTION
The alarms function monitors internal relay systems, external relay interfaces, and power system
equipment. Alarm points are segregated into Relay Trouble Alarms and Programmable Alarms. Alarm
point status is stored in nonvolatile memory and is retained when relay operating power is lost.
The ability to program the reporting and display of alarms along with the automatic display priority feature
of the HMI gives the relay the functionality of a local and remote alarm annunciator. See Section 10,
Human-Machine Interface, for more information on the automatic display priority logic.
Relay Trouble Alarms
All internal circuitry and software that affects how the relay functions is monitored by the continuous self-
test diagnostics function of the relay trouble alarms. A detailed list of relay trouble alarms is provided in
Table 6-19. If any one of these points asserts, the failsafe alarm output relay de-energizes and
closes/opens (depending on style number) the OUTA contact, the HMI Relay Trouble LED lights, all
output relays are disabled, logic variable ALMREL is set and the relay is taken offline. The relay trouble
alarms function is not programmable.
If your application requires a normally closed contact that opens to indicate a relay trouble condition, use
BESTlogic to program the output logic. One of the output relays with normally open contacts (OUT1
through OUT5) can be programmed to be held closed. For example, to open OUT5 for indication of relay
trouble, set the VO5 logic expression at /0 (SL-VO5=/0). A not zero setting is equal to logic 1. When the
relay is fully functional, the OUT5 output contact is closed. Since all output relays are disabled when a
relay trouble alarm exists, OUT5 opens when relay trouble occurs.
