Basler Electric BE1-851 - Manual (Page 122)

Pickup
Pickup expressions are used by the fault reporting function to time-stamp the fault summary record, time
the length of the fault from pickup to dropout (fault clearing time), and to control the recording of
oscillographic data. The pickup expression is used to flash, on and off, the Trip LED on the HMI. The Trip
LED will continue to flash on and off as long as the pickup expression is true and the trip expression is not
true. A pickup expression is also used by the setting group selection function to prevent a setting group
change during a fault.
Logic
LOGIC trigger expressions allow the fault reporting function to be triggered even though the relay is not
picked up. A logic trigger expression provides an input to the fault reporting function much as the pickup
expression does. This logic expression is not used by the setting group selection or the HMI.
Fault Reporting Trigger Settings
Fault reporting trigger settings are made from the BESTlogic Function Element screen in BESTCOMS.
Figure 6-12 illustrates the BESTCOMS screen used to select BESTlogic settings for the Fault Recording
function. To open the BESTlogic Function Element Screen for Fault Recording, select Reporting and
Alarms from the Screens pull-down menu. Select the Fault Recording tab. Then select the Logic button in
the upper left hand corner of the screen. Alternately, settings may be made using SG-TRIGGER ASCII
command.
To connect the function’s inputs, select the button for the corresponding input in the BESTlogic Function
Element screen. The BESTlogic Expression Builder screen will open. Select the expression type to be
used. Select the BESTlogic variable or series of variables to be connected to the input. Select Save when
finished to return to the BESTlogic Function Element screen. For details on the BESTlogic Expression
Builder, See Section 7, BESTlogic Programmable Logic. Select Done when the settings have been
completely edited. Trigger settings for fault reports are made using the SG-TRIGGER (settings-general,
trigger) command.
