BE1-CDS220 Reporting and Alarm Functions 6-41
Major, Minor, and Logic Programmable Alarms
The programmable alarms function covers all circuits monitored by the continuous self-test diagnostics
function that do not affect the relay core functions. Alarm functions used to monitor the power system and
equipment are also part of the programmable alarms. Table 6-21 provides a detailed list of all
programmable alarms. The programmable alarm points can be prioritized into Major and Minor alarms
using BESTCOMS. Major alarm points, when triggered, causes the HMI Major Alarm LED to light and the
BESTlogic variable ALMMAJ to assert. Minor alarm points, when triggered, causes the HMI Minor Alarm
LED to light and the BESTlogic variable ALMMIN to assert.
Any programmable alarm can also be used in programmable logic expressions without programming it to
be reported by the programmable alarm reporting function. The ALMLGC variable is provided for this
purpose. Programmable alarm variables can be masked to drive BESTlogic variable ALMLGC by using
the SA-LGC command.

I.D. # Name Description
1 OUTPUT CKT OPEN
∗
Output circuit continuity monitor alarm.
2
BKR FAIL ALARM
∗
Breaker failure trip.
3 DIFFERENTIAL ALARM Differential threshold exceeded.
4 CHANGES LOST ALARM Access lost.
5 BREAKER ALARM 1 Breaker Alarm 1 threshold (SA-BKR1 setting) exceeded.
6 BREAKER ALARM 2 Breaker Alarm 2 threshold (SA-BKR2 setting) exceeded.
7 BREAKER ALARM 3 Breaker Alarm 3 threshold (SA-BKR2 setting) exceeded.
8
P DEMAND ALARM
∗
Phase demand alarm.
9
N DEMAND ALARM
∗
Neutral demand alarm.
10
Q DEMAND ALARM
∗
Excessive negative-sequence unbalance alarm.
11 GROUP OVERRIDE
∗
Setting group override in effect.
12 SYS I/O ALARM Excessive delay in operation of HMI or serial communications.
13 COMM ERROR ALARM Communications failure.
14
CLOCK ERROR
∗
Real time clock has not been set.
15 uP RESET ALARM Microprocessor has been reset.
16 SETTINGS CHANGE Settings change made by user.
17 EE NON FATAL ERROR EEPROM non-fatal recoverable error.
18
OUTPUT OVERRIDE
∗
An override condition is active in one or more outputs.
19
LOSS OF IRIGB
∗
Loss of IRIG sync.
20 SGC ACTIVE Setting group change alarm active.
21 VO13_LABEL
∗
VO13 logic if TRUE. (User programmable logic alarm.)
22 VO14_LABEL
∗
VO14 logic if TRUE. (User programmable logic alarm.)
23 VO15_LABEL
∗
VO15 logic if TRUE. (User programmable logic alarm.)
24 FAULT REPORT TIMEOUT TRUE if fault event trigger lasts longer than 60 seconds.
25 TRANSFORMER ALARM 1 Transformer Alarm 1 threshold (SA-TX1 setting) exceeded.
26 TRANSFORMER ALARM 2 Transformer Alarm 2 threshold (SA-TX1 setting) exceeded.
27 TRANSFORMER ALARM 3 Transformer Alarm 3 threshold (SA-TX1 setting) exceeded.
28 LOGIC = NONE ALARM No logic selected.
∗
Alarms with an asterisk are non-latching. A non-latching alarm clears itself automatically when the alarm
condition goes away. All other alarms are latching and must be manually reset by using the HMI Reset
button or the RA=0 command.
