Example: If your system uses 100 FD102TURF Field
Decoders (each operating one solenoid output), then
test results should show a
Before reading of about
50 mA, Inrush of 525 mA (which is within the 290-
700 range), and a
hold
of 70 mA (which is 20 mA
higher than the Before reading).
Note: If the Before , Inrush and hold values are
close, the decoder is not responding. Locate the
decoder in the field and make sure that it is wired
properly to the solenoid and communications cable.
You should also make sure you programmed in the
right
Decoder Addresses (REC . NO .) .
5. Press the button pointing to the OK label twice
to activate and test the next decoder in line.
6. The minus (-) label cancels the test at any time,
returning to the Test menu.
Note: To set up the MDC2 Controller to
automatically activate and test each decoder in
sequence, please see
Setting Up an Automatic
Test Program on page 48.
