3.4.2 Diagnostic Indication Simulation. Magnetrol Pulsar R96 HART

44

Refer to the Diagnostic Indicator tables in Section 3.4 for a complete listing of the Model R96 diagnostic indicators, along with their explanations, default categories, and recommended remedies.

NOTES: 1) The remedies shown in this table can also be seen on the transmitter LCD by viewing the present status screen when the device is in a diagnostic condition.

2) Those indicators showing failure as the default result in an alarm condition.

3.4.2 Diagnostic Indication Simulation

The DD and DTM allow for the ability to manipulate diagnostic indicators. Intended as a means to verify the configuration of the diagnostic parameters and connected equipment, a user can manually change any indicator to and from the active state.

3.4.3 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 3.4) is displayed on the bottom LCD line. 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 nameexplanation pairs) exceeds the available space, a appears in the rightmost 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 parameters related to some of the advanced diagnostics available within the Model R96.

INTERNAL VALUES

– Displays read-only internal parameters.

ELEC TEMPERATURES

– Displays temperature information as measured in the electronics 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 on the LCD.
