H9 ASD Installation and Operation Manual

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
Trip History
screen
(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
Table 15
as At-trip Recorded Parameters (parameter readings at the time that the trip
occurred).
Table 15. Trip History Record Parameters.
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. 43
). 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 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).
Clearing a Trip
Once the cause of the trip has been corrected, performing a
Reset
re-enables the H9 ASD for normal
operation.
The record of a trip may also be cleared using either of the following methods:
• Cycling power (trip info may be saved via
F602
if desired),
• Pressing the Stop|Reset key twice,
• Remotely via the communications channel,
• Momentarily connecting terminal RES to CC of the Terminal Board, or
• Via Program
