generate a trigger from a logic zero, the selected signal will not be listed in the
indications list of the disturbance report.
Analog-signal trigger
All analog signals are available for trigger purposes, no matter if they are recorded
in the disturbance recorder or not. The settings are OverTrigOp, UnderTrigOp,
OverTrigLe and UnderTrigLe.
The check of the trigger condition is based on peak-to-peak values. When this is
found, the absolute average value of these two peak values is calculated. If the
average value is above the threshold level for an overvoltage or overcurrent trigger,
this trigger is indicated with a greater than (>) sign with the user-defined name.
If the average value is below the set threshold level for an undervoltage or
undercurrent trigger, this trigger is indicated with a less than (<) sign with its name.
The procedure is separately performed for each channel.
This method of checking the analog start conditions gives a function which is
insensitive to DC offset in the signal. The operate time for this start is typically in
the range of one cycle, 20 ms for a 50 Hz network.
All under/over trig signal information is available on the local HMI and PCM600.
