Note: The event that caused the Trip(s) must be corrected or must decrease to less than the threshold
value required to cause the trip to allow for a Reset to be recognized. In the event of multiple
active trips, the trip displayed will remain until all faults are corrected and all trips are cleared.

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 ASD Faults and a Trip is incurred.
When a trip occurs, the resultant error information may be viewed either from the
(Program ⇒ Monitor Setup ⇒ Trip History), the
Setup ⇒ Trip Monitor From ASD), or from the Monitor screen.
Trip History
The Trip History screen records the system parameters for up to 101 trips (RTC option required). The
recorded trips are numbered from zero to 100. Once the Trip History record reaches trip number 100, 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
the trip occurred).
Table 13. Trip History Record Parameters (RTC option required).
Trip records that are assigned zero and one are comprised of the full list of monitored parameters (32).
Trip records 2 – 18 are comprised of parameters 1 – 16. Trip records 19 – 100 are comprised of
parameters 1 – 7.
