Viewing Trip Information
In the event that the condition causing an Alarm does not return to the normal operating level within a
specified time, the H9 ASD Faults and a Trip is incurred.
When a trip occurs, the resultant error information may be viewed either from the
(Program ⇒ Utilities ⇒ Trip History) or from the Monitor screen.
Trip History
The Trip History screen records the system parameters for up to 20 trips. The recorded trips are
numbered from zero to 19. Once the Trip History record reaches trip number 19, the oldest recorded trip
will be deleted with each new record stored (first-in first-out). The Trip # field may be selected and
scrolled through to view the recorded trip information for a given trip number. The monitored parameters
are listed in

Trip records are comprised of the full list of monitored parameters (28).
Trip Record at Monitor Screen
The at-trip condition of the last 4 incurred trips may be viewed at the Monitor Screen. The Monitor
Screen displays the records of up to four trips and catalogs each trip as Past Trip #1 through Past Trip #4
(see
pg.

powered up or since the last reset, None is displayed for each trip record.
The Monitor Screen at-trip record is erased when the H9 ASD is reset.
Note:
An improper H9 ASD setup may cause some trips — reset the ASD to the Factory
Default settings before pursuing a systemic malfunction (Program ⇒ Utilities ⇒ Type
Reset ⇒ Reset to Factory Settings).
