Fault Indications by Relay #6
By default, two fault conditions are monitored and activates relay #6:
1. Ethernet connection to the local network is lost
2. Internet connection to the uplink server is lost
When either of these conditions happen, relay #6 is triggered and the front panel shows the
relay #6 active (dark box) and the cleared status boxes indicate where the problem is. The
last of the relay boxes is dark and one or more of the boxes in the middle of the screen, as
described in the
Front Panel Description section, are clear. For example, if relay #6 was
triggered and the front panel indicated a loss of connectivity to the Internet, you would know
that the receiver still had the local network was still connected to your local network.
The front panel here shows relay #6 active and the “Inet” box is clear indicating a problem
with the Internet connection.
An alarm (aural or visual) can be attached to any relay to indicate a fault.
Time Sync by Relay #5
To keep clocks synchronized at your station, a time pulse can be used from the AMR-100-I.
Every hour, relay #5 can close for one second as a time sync pulse. This can be at any minute
and second of the hour. The pulse can happen at HH:56:30 or HH:00:00. Setting this is done
through the font panel menu and can be found in the
Clock Interval section.
Program use of Relays #5 and #6
Relays #5 and #6 can also be used for programming functions, but then they cannot be used
for alarms or time syncing your clock. You can use #6 for an alarm and not use the clock
sync function and have relays #1-#5 available for programming functions (see
Closure Map ).
The same thing is true if you use #5 for time syncing and do not use #6 for alarms. That
would give you relays #1-#4 and #6 for programming functions (see
Closure Map ).
If you do not use the Time Interval relay (#5) to set your clocks or the alarm relay (#6) for
network failures, then you can assign these two relays (#5 and #6) to one of the programming
functions (see
Closure Map section). Relays #5 and #6 can be used to send closures to your
automation system. However, if you decide to make use of the alarm or Time Interval later,
you must change the relay function assigned to #5 or #6 to another available relay. If you do
not do this, if a program provider sends a command that closes one of them, your alarm

WARNING
If you assign relays #5 or #6 to a programming function and then turn on the
alarm or Time Interval, you must go back to the Relay Map and change the
assignment to another available relay or you will get unpredictable results. The
Relay Map does NOT change automatically when the alarm or Time Intervals are
activated.
