WIRE TEST
The wire test will place a 60 Hz frequency on all output
modules and their two-wire paths, to allow wire tracking and
fault nding with a standard AC current clamp meter. This is a
common diagnostic technique to nd shorts to earth ground.
The AC current will drop sharply between two points on the
wire path, if the short circuit or fault to earth is between them.
When troubleshooting is nished, press the so key again to
turn o the 60 Hz wire test mode.
DECODER INVENTORY
This runs a test communication to all decoder addresses on
the selected output module to verify which decoders are
installed and operational on the two-wire paths. Use the
inventory when station performance issues are suspected, or
when assessing a new or undocumented control system.
To start the inventory, press the Update so key. The
controller will look for station addresses on all modules, and
wait for responses. The process may take several minutes.
At the end of the inventory, the screen will show a report of
all decoders found, with a screen for each individual decoder
output module.
The report will indicate decoder type, station number, success
rate (comm %) and the rmware update status, by decoder
output module.
Use the Next Module so key to view the results on each
module, one at a time.
