Alarms, Trips, and Troubleshooting
W7B ASD Installation & 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, a Trip is incurred.
When a trip occurs, the resultant error information
may be viewed either from the 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. The recorded trip
events 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
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
). 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
if desired),
•
Pressing the Stop-Reset 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 Past Trips.
