RTM Elster AMCO applicative PFS Coronis Systems
5.12.Faults or Flow Problems automatic transmission
(Refer to DR[3] Section 1.0.25 to 1.0.27; DR[4,5] Section 1.0.22 to 1.0.24)
RTM Elster AMCO module offers the possibility to automatically transmit radio frames when an occurrence is
detected. The following occurrences may provoke an automatic alarm :
Extreme Leak detection (High threshold)
Residual Leak detection (Low threshold)
Encoder Communication fault detections (encoder register only)
encoder reading error detection (encoder register only)
Tamper detection (pulse register only)
Low Battery warning detection
Back flow detection (encoder only)
It is possible to select for each type of occurrence whether or not an alarm frame is to be sent.
5.12.1.Time windows dedicated to alarm sending
Activating alarm in a system already configured to send information using pseudo bubble up mechanism can
lead to collisions. To avoid as much as possible these collisions RTM Elster AMCO embeds a parameter
that allows to configure time windows dedicated to alarm. These time windows will then not be used for
Pseudo Bubble Up time slot attribution. This mechanism allows to mix either Pseudo Bubble Up mechanism
and Alarm frame management without affecting system accuracy.

bit 7 bit 6 bit 5 bit 4 bit 3 bit 2 bit 1 bit 0
Time Slot Granularity:
“000” = every quart hour (start on hour on dot of RTC)
“001” = every 30 minutes (start on hour on dot of RTC)
“010” = every hour (start on hour on dot of RTC)
Time slot duration:
“000” = 30 secs
“001” = 45 secs
“010” = 60 secs
“011” = 90 secs
“100” = 120 secs

“00” = Disable
“01” = Enable
Example of Alarm Windows activation
In this example, to activate alarm windows every hour during 60 seconds, the parameter “Alarm Window
configuration” (0x57) must be set to 0x69.
By using this configuration the RTM Elster AMCO will allow alarm frame during 30 seconds every hour and
will start the first time on hour on dot taking into account its internal RTC.
