Table 2-5The CubicleBUS LED provides information on the state of CubicleBUS communication in the COM16 module.

When the circuit breaker is fully withdrawn, no further microswitches are actuated. "Circuit breaker fully withdrawn" is communicated immediately.

The sequence described above provides hysterisis for communicating contact position and avoids intermittent contact postitions from being communicated.

With UL 489 fixed-mounted circuit breakers, a heel plate is screwed to the COM16 module to transmit operating position.

The COM16 module features a built- in temperature sensor, which is installed outside the circuit breaker, and measures the temperature surrounding the breaker.

It also contains a clock that provides a time stamp for all events, such as minimum and maximum measured values, as well as warnings and trips.

Table 2-6The COM16 module has 3 microswitches for determining the position of the circuit breaker in the guide frame. Depending on which switch is actuated, the position described above is communicated via the comm. system (1=contact closed, 0=contact open).

Three microswitches located in the COM16 module can determine the position of a drawout circuit breaker in the guide frame, which is then communicated via the COM16 module. The positions are defined in Table 2-6. When the position of the circuit breaker has changed, the microswitch that has been actuated is opened before the next microswitch is actuated. No microswitches are actuated if the breaker is between two of the three positions. The previous state is communicated until a new position is reached when the circuit breaker is moved (see Table 2-6).

There is no way of determining the direction in which the circuit breaker is being moved once the "disconnect position" microswitch has been opened.

When the circuit breaker is initially racked in, the next microswitch to be actuated is the "test position." The COM16 module communicates "circuit breaker not present" until the "test position" key is actuated. The new event message is delayed by 10 seconds to ensure that the breaker is firmly seated.
