4.0 BINARY OUTPUTS
Binary outputs are simply pairs of mechanical wipe relay contacts. They can be employed to
switch in other circuitry or to an alarm indicator. See Illustration 3 and 4 for the power limitations
of the contacts. Notice the flat curve for AC voltage in Illustration 4. On the inside of the low volt-
age cabinet there is a membrane style button plate that contains a “Ready” LED. The Ready light
will either flash or turn off depending on the state of the Capacitor voltage, Coil continuity, and
the state of the position sensors. The “Unit Ready” output contact can be used to alarm for the
more serious of the three types of problems, but will not signal for all levels of the above prob-
lems. See Illustration 6.
4.1 Circuit Breaker Opened (KM1004 Pins 1 and 2)
The Circuit Breaker Opened contacts are normally open. They close only when the circuit break-
er is in the Open position.
4.2 Circuit Breaker Closed (KM1004 Pins 3 and 4)
The Circuit Breaker Closed contacts are normally open. They close only when the circuit breaker
is in the Closed position.
4.3 Circuit Breaker Auxiliary Open (KM1004 Pins 5 and 6)
The Circuit Breaker Auxiliary Open contacts which close whenever the breaker is in the Open
position.
4.4 Circuit Breaker Auxiliary Closed (KM1004 Pins 7 and 8)
Additional set of normally open contacts which close whenever the breaker is in the Close posi-
tion.
4.5 Unit Ready (KM1004 Pins 9 and 10)
These contacts are normally open. They close when the breaker is ready. They are used to mon-
itor capacitor charge (O-CO operation ready), valid circuit breaker position, and coil continuity.
4.6 Unit Not Ready (KM1004 Pins 11 and 12)
The Unit Not Ready contacts are normally closed. They open when the Unit is Ready. These
contacts are the inverse (negative) of the Unit Ready contacts.
When using the Not Ready contacts to provide an alarm to SCADA, an 8 second delay is recom-
mended since the unit will go to Not Ready when the capacitors are below 49 V. The 8 second
delay allows the capacitors to charge prior to alarming.
4.7 Circuit Breaker Remote Open (KM1004 Pins 13 and 14)
The Circuit Breaker Remote Open contacts are referred to as the “Fleeting Output Contacts.”
This means that they only close for 100 milliseconds after a Remote Operation is performed.
