PROBLEMS
No display on the ML-10-KD keyboard.
(If there is display but NO response to
input on the keyboard - continue with the
next diagnostic problem below.)
If you see NO display on the keyboard
then there is NO power output from the
datalogger of the weather station.
Pins 1 and 2 of the Serial I/O connector
should give +5 Volts DC.
If NO voltage is found - then check for
incoming power to the weather station -
starting at the transformer check for 110
volts AC power to the transformer.
Check for +16 Volts AC coming from
the secondary side of the transformer.
Check for +16 Volts AC at the two (2)
terminals marked “CHG” on the panel of
the ET Enclosure. (Refer to FIGURE 9
for location of +16VAC terminals).
If you have power all the way to the
datalogger PC board - then you must
replace the datalogger PC board and
have the original datalogger PC board
repaired.
No response using the keypad and/or
erroneous letters in the display.
