APPENDIX C: EXTERNAL MUTING AND EXTERNAL WARNING RELAYS
CONFIGURING WARNING RELAYS IN THE
RMSERVER WEB SERVER
RMServer contains two relays that can be set to trigger
when specified failure conditions occur. failsafe conditions
also can be specified which, when met, cause the relays to
be reset. These relays are connected to external devices to
trigger appropriate actions in those devices.
NOTE:
RMServer must be discovered by the
Compass control software before it can be
used for warning relays. Once RMServer has been
discovered, Compass software must be running for
warning relay functions to operate.
To enable and configure RMServer's warning relays:
1. Access RMServer's web server page as described in
"Accessing the RMServer Web Server" on page 12.
2. On the Basic Settings tab, the Relay Configuration sec-
tion displays the currently enabled failure conditions for
each relay which will trigger it to change state.
Figure 5: Relay Configuration section of the Basic Settings page of
RMServer's web server.
3. To change the conditions specified for one or both
relays, click the Setup button in the Relay Configuration
section to open the Edit Relay Setup dialog.

fault is detected, or the Load faults repeat 3 times

other relay and configure its failure conditions.

activate one or both conditions that signal restoration of
proper operation and trigger resetting of the selected
relay to its default state.

from load fault box is checked, then check the Instantly
(no threshold) box to reset the relay as soon as all load
faults are cleared, or the Load faults are clear for 5
minutes box to reset the relay only after no faults have
occurred in the five minutes following clearing of the fault
