SED2 AOP Operating Instructions

Multiple Faults

If a SED2 VFD or network of VFDs reports more than one fault condition, the AOP displays all
fault messages by cycling through them until they are all cleared. See Fault Indication/Fault
Screen in this chapter to acknowledge each fault message.

Multiple Warnings

If a SED2 VFD or network of SED2 VFDs reports more than one warning condition, the AOP
displays all warning messages by cycling through them until the conditions causing the warning
messages cease to exist.

Simultaneous Faults and Warnings

If a SED2 VFD or network of VFDs reports a fault condition and a warning condition, the AOP
displays all messages by cycling through them. The AOP first displays a fault message and then
a warning message separated by a 2-second interval.
This cycle continues until all fault and warning messages display. The cycle repeats itself until all
fault messages are either acknowledged or cleared and the conditions causing the warning
messages cease to exist.
