Figure 1-8 EntelliGuard Messenger
The Messenger is located directly above the circuit breaker compartment.
1.3.5.2 Active Health Monitoring
The Entellisys Messenger actively monitors critical internal circuits which is displayed on the HMI
in the System Health screen. The HMI can also annunciate alarms on the following circuits:
• Communications channels A and B
• Control Power channels A and B
• Ibutton health
• Flux Shifter circuitry
Alarm Annunciation
User configured alarms can be configured at the HMI to annunciate locally, send
auto-generated email or programmed to energize an annunciator light (discrete I/O required).
(see
Alarms on page 215 ).
The Messenger health alarms that can be configured are:
Flux Shifter Alarm
Messengers with hardware revision 5 and beyond, have a monitoring circuit which monitors the
Flux Shifter circuitry to ensure that it is armed and capable of tripping the breaker.
NOTE: This circuitry does not monitor the Flux Shifter coil or the electrical/mechanical
connections between the Messenger and the coil.
Compartment ID Button Missing
Indicates that the compartment ID button is either missing, damaged or not installed correctly.
(See
Compartment ID button on page 21 ).
Messenger Communication Lost
Each Messenger has redundant ethernet channels (ethernet channels 1 and 2). This alarm
indicates that either comm 1, comm 2 or both channels have stopped communicating to the
default CPU.
Redundant CPU Messenger Comm Lost
Similar to the Messenger Communication Lost alarm above except it monitors the comm on the
redundant CPU.
