board. If the problem persists, replace the card.
Aux. Card 1 No Loop Power
•
Definition: Auxiliary Card 1 has no loop current.
•
Possible Solutions: Check auxiliary card connection to loop current. If
the problem persists, replace the card.
Aux. Card 1 Error
•
Definition: Auxiliary Card 1 has an electrical problem.
•
Possible Solutions: MFC: Check auxiliary loop wiring and ensure
adequate compliance voltage. Replace card if condition persists
Aux. Card 2 Fail
•
Definition: Auxiliary Card 1 is not communicating.
•
Possible Solutions: Check auxiliary card connection to the main
board. If the problem persists, replace the card.
Aux. Card 2 No Loop Power - Auxiliary Card 2 has no loop current
•
Definition: Auxiliary Card 2 has no loop current.
•
Possible Solutions: Check auxiliary card connection to loop current. If
the problem persists, replace the card.
Aux. Card 2 Error
•
Definition: Auxiliary Card 2 has an electrical problem.
•
Possible Solutions: MFC: Check auxiliary loop wiring and ensure
adequate compliance voltage. Replace card if condition persists
Pressure Board Fail Warning
•
Definition: One or more pressure sensors may have failed.
•
Possible Solutions: Check the supply pressure to ensure it is between
1.3 and 10.3 bar (19 and 150 PSI). Check the pressure sensor board
connections. Recalibrate the pressure sensors. If the problem persists,
replace the pressure sensor board.
Low Battery Warning
•
Definition: The battery for the real time clock is low.
•
Implications: The battery is designed for a 15+ year life with the
positioner unpowered. The battery is not required for the positioner to
control properly, but is used only to maintain the time and date upon
loss of power. The time and date affect the time stamps of alarms,
warnings and other events. This warning could be caused by rapidly
power cycling the positioner.
•
Possible Solutions: The battery is not replaceable. Verify or reset the
time and date. Replace the main board if the problem persists for
several days.
