3.3 Controlling circuit breakers
Entellisys allows users to control EntelliGuard circuit breakers from the HMI. A circuit breaker
may be commanded to open, close or trip. To locate or confirm the circuit breaker shown on the
HMI screen matches the physical circuit breaker, the locator LED on each EntelliGuard
Messenger can be set to flash for 10 or 30 seconds.
To control a circuit breaker, navigate to the Breaker Status screen and click Control as shown in
Figure 3-5. The Breaker Control screen appears. The Breaker Control screen resembles
Figure 3-7 when the circuit breaker is open. The Breaker Control screen resembles Figure 3-8
when the circuit breaker is closed.

3.3.1 Block other HMIs
Any HMI that is designated as a Local HMI can block other HMIs from operating circuit breakers.
To designate an HMI as local, click the Modbus Security tab under the Maintenance menu.
When the check box on that screen is checked, the HMI is the Local HMI.
