Trigger Defines whether you want a continuous or a single-
shot trigger. Pressing this key will place an S or a C
in front of the trigger parameter. You will almost
always want a Single-Shot (S) trigger.
S = Single shot>>the trigger occurs once and stops,
trigger must be manually re-armed
C = Continuous capture>>auto re-arm enabled to
collect new trends until stopped by viewing contents
of captured data
Cond Defines the Condition that will cause the trigger. The
possible options are:
= Equal to
+ Boolean OR
N= Not Equal to N+ Boolean NOR
> Greater than & Boolean AND
< Less than N& Boolean NAND
Data Defines the trigger value with respect to the Read-
Only Parameter in Trace 1.
View
The view feature is used to observe the samples recorded during the
last diagnostic trend.
How to Setup Trending
The trending setup is best illustrated through an example:
Trend Read-Only Parameters
1 – Status Flags (569)
2 – Pressure Value (447)
3 – Alpha Line (327)
4 – Speed Feedback (289)
5 – IDC Reference (321)
6 – IDC Feedback (322)
7 – Torque Reference (291)
8 – I Stator (340)
The sample rate is to be set at 0 msec. This will default to the fastest
sample rate. 20% of the samples should be recorded after the trigger.
The single trigger should occur when any fault occurs.
