Viewing Trip Information

In the event that the condition causing an Alarm does not return to the normal operating level within a specified time a Trip is incurred.

When a trip occurs, the resultant error information may be viewed either from the Trip History screen

(Program System Information and Setup

Trip History) or from the Monitor screen.

Trip History

 

The Trip History screen records the system parameters for up to 24 trips (RTC option required). The recorded trips are numbered from zero to 23. Once the Trip History record reaches trip number 23, 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 14 as At-trip Recorded Parameters (parameter readings at the time that the trip occurred).

Trip Record at Monitor Screen

The Monitor screen records and displays the trip name of up to four trips and catalogs each trip as Past Trip #1, Past Trip #2, Past Trip #3, and Past Trip #4. Once reset (Clear Trip), the trip records are erased. If no trips have occurred since the last reset, No Error is displayed for each trip record.

Note: An improper ASD setup may cause some trips — reset the ASD to the factory default

settings before pursuing a systemic malfunction (Program

Utilities

Type Resets

Restore Factory Defaults).

 

 

The at-trip frequency of the last incurred trip may be viewed at the Monitor screen (see pg. 45). The Monitor screen at-trip record is erased when the ASD is reset and may be viewed without the use of the RTC option. The current output frequency is displayed here when no trip is active.

Clearing a Trip

Once the cause of the trip has been corrected, performing a Reset re-enables the ASD for normal operation (clears the fault screen).

The fault screen may also be cleared using either of the following methods:

Cycling power (trip info may be saved via parameter 0602 if desired),

 

Pressing the StopReset key twice,

 

 

 

Remotely via the communications channel,

 

 

 

Momentarily connecting terminal RES to CC of the Control Terminal Strip, or

 

Via Program

Utilities

Type Resets

Clear Psast Trips.
