5.9.Tamper detection (pulse register only)
Tamper detection is possible if the cable sensor is 3-wire type. In such a case, the 3
rd
wire is connected to a
module input in the same way as the metering input.
Tamper detection is activated by setting bit 4 in the “Operating Mode” parameter.
When Tamper detection is activated, RTM Elster AMCO checks periodically (every second) the state of this
input (0 means no tamper , 1 means tamper). Once a tamper has been detected (input level = 1), RTM Elster
AMCO sets bit 4 in the “Application Status” parameter.
