ESPLXD-ET Controller
Ping Decoders
The ESPLXD-ET controller can provide detailed information on a
specific decoder.
This can be helpful to narrow a repair trip into the field to one decoder
or a set of decoders on a particular branch of the two wire path. You can
ping a Station decoder, MV decoder or Sensor decoder. Interpretation
of the results is essentially the same for station and MV decoders.

Interpreting Ping Results
b
l
The Prior amperage is based on line current for your system and
should be about the same as the previously Calculated System
Amperage.

The In-Rush current reading is typically less than 200 mA. A reading
of 100 mA or less typically indicates an open output, often caused
by a poor connection from the solenoid to the valve.
