ADM means the ADM99 decoder output module, and shows that the meter or sensor input has been assigned to an
ICD-SEN sensor decoder in the two-wire path.
ET followed by a sensor name means the input has been assigned to an ET Sensor.
ET Functions are described in their own section in this manual.
Event Mode Functions are described in their own section in this manual.
Decoder Functions are described in their own section in this manual.
Common alarm (aTTenTIon) messaGes ....................................
OVERCURRENT
In a conventionally-wired controller with ACM600 or AGM600
outputs, Overcurrent means that the station has exceeded
0.56 Amps output. This indicates that either too many
solenoids are connected or the field wiring or solenoid has a
problem, causing an unacceptably high current. All solenoids
are different and not all solenoids may be “doubled” on an
ACC output. A solenoid with a holding current of 0.3 A is
acceptable, but two of them (equaling 0.6 A) would exceed
the 0.56 A max limit and cause an Overcurrent.
In decoder controllers, Overcurrent may have more
complex causes, but still indicates an unacceptable high
current on the decoder line.
The Alarm Log will indicate whether the alarm was
associated with a station number, or "ADM", referring to
the ADM99 decoder output module.
A station Overcurrent in a decoder system indicates a
high-draw condition on the output side of the decoder, to
the solenoids, usually a shorted solenoid.
