2.3.4 Diagnostic Help
Selecting DIAGNOSTICS from the MAIN MENU presents a
list of five ITEMS from the top level of the DIAGNOSTICS
tree.
When Present Status is highlighted, the highest MAGNETROL
priority active diagnostic indicator (numerically lowest in Table
3.3.3) is displayed on the bottom LCD line, which is “OK”
as shown at left. Pressing the ENTER key moves the active
diagnostic indicator to the top line outdented and presents in
the lower area of the LCD a brief explanation of and possible
remedies for the indicated condition. A blank line separates the
explanation from the remedies. Additional active diagnostic
indicators, if any, appear with their explanations in descending
priority order. Each additional active indicator name-explanation
pair is separated by a blank line from the one above.
If the explanation and remedy text (and additional name expla-
nation pairs) exceeds the available space, a appears in the right-
most column of the last line indicating more text below. In this
situation, the DN key scrolls text up one line at a time. Similarly,
while text exists above the upper line of the text field, a appears
in the rightmost column of the top (text) line. In this situation,
the UP key scrolls the text down one line at a time. Otherwise
the DN and UP keys are inoperative. In all cases the ENT or
DEL key reverts to the previous screen.
When the transmitter is operating normally and the highlight
cursor is positioned on Present Status, the bottom LCD line
displays “OK” because no diagnostic indicators are active.
EVENT HISTORY
– This menu displays the parameters related
to diagnostic event logging.
ADVANCED DIAGNOSTICS
– This menu displays parame-
ters related to some of the advanced diagnostics available within
the Model JM4.
INTERNAL VALUES
– Displays read-only internal param-
eters.
ELEC TEMPERATURES
– Displays temperature informa-
tion as measured in the potted module in degrees F or C.
TRANSMITTER TESTS
– Allows the user to manually
set the output current to a constant value. This is a method
for the user to verify operation of the other equipment in
the loop.
ECHO CURVES
– This menu allows the user to display the live
Echo Curve and Echo Rejection on the LCD.
