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 P9 ASD
Faults
and a
Trip
is incurred.
When a trip occurs, the resultant error information may be viewed either from the LED screen, LCD
Fault
screen (
Monitor
screen, or the
screen
(Program
Utilities
).
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
for more info.). Once reset (
Type Reset
), the trip records are erased. If no trips have occurred
since being powered up or since the last reset,
None
is displayed for each trip record.
The
Monitor
screen at-trip record is erased when the P9 ASD is reset.
Note:
An improper P9 ASD setup may cause some trips — Save the existing parameter profile
via Program\Utilities\
Save/Restore Wizard
and then reset the ASD to the
Factory
Default
settings before pursuing a systemic malfunction (Program
Utilities
Type
Reset
Reset to Factory Settings
).
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
At-trip Recorded Parameters
(parameter readings at the time that the trip
occurred).
In the event of a power loss or if the keypad has been removed from the ASD, the trip records and the
real-time clock information are retained within the keypad for up to 4.5 years via
.
Table 7. Trip History Record Parameters.
Clearing a Trip
Once the cause of the trip has been corrected, performing a
re-enables the P9 ASD for normal
operation.

Clear Past Trip
(clears Monitor screen records only).
