BE1-CDS220 Reporting and Alarm Functions 6-19
SA-TX Command
Purpose:
Read/Set transformer alarm settings
Syntax: SA-TX[n][={mode},{alarm limit}] where mode=0-2(disabled/%duty/#thflts)
Comments: [n] = 1, 2 or 3 where 1 = alarm point number 1, 2 = alarm point number 2, 3 = alarm point
number 3.
SA-TX Command Example:
Example 1. Program alarm point 1 to alarm on 20 through faults, alarm point 2 to alarm on 50% duty,
and alarm point 3 to alarm on 80% duty.
>SA-TX1=2,20
>SA-TX2=1,50
>SA-TX3=1,80
BREAKER MONITORING
Depending on the system scheme, one BE1-CDS220 relay can provide overcurrent protection for more
than one circuit breaker. However, breaker-monitoring functions provide extensive monitoring and alarms
for only a single circuit breaker. This extensive monitoring helps to manage equipment inspection and
maintenance expenses. Breaker monitoring functions include breaker status and operations counter
reporting, breaker fault current interruption duty monitoring, and breaker trip speed monitoring. Each of
these functions can be programmed as a programmable alarm. See Alarms Function in this section for
more information on the use of programmable alarms.
Breaker Status Reporting
The breaker status monitoring function monitors the position of the breaker for reporting purposes. It also,
counts the opening strokes of the breaker and records them in the breaker operations counter register.
Setting the Breaker Status Reporting Function
Since the relay is completely programmable, it is necessary to program which logic variable is to be
monitored for breaker status. This is done with BESTCOMS. See Breaker Status Logic in the lower left
corner of the screen shown in Figure 6-8. Alternately, the ASCII command SB-LOGIC (setting breaker,
logic) can be used. It should be noted that even though a BESTlogic logic expression is used to make this
setting, this setting is not included in the section on BESTlogic settings. We include it here because it is
related to breaker monitoring. See Section 7, BESTlogic Programmable Logic, for more information on
the use of BESTlogic for programming the relay. When you program SB-LOGIC, the breaker name that
you set also labels the 101 Virtual Breaker Control Switch. For more information on this switch, refer to
Section 4, Protection and Control, 101 Virtual Breaker Control Switch.
