BE1-BPR Functional Description
CAUTION
A pickup setting range check is made each time logic settings are changed that affect the fault
detector pickup settings. For example, if PU1=5.00 and LF1 setting is changed from PI,1 to PI,2,
the PU1 setting will automatically change from 5.00 to 1.00 (the maximum allowable setting for
a Type 2 fault detector on a 5 A unit). This kind of pickup setting adjustment can also occur if the
active relay logic is replaced with logic that has different LF settings.

The PU command sets the trip value of each fault detector and the moving average filter cycles for Type 2
fault detectors.

NOTE: Types 1 and 3 PU settings can be set below the stated minimum settings. However,
specified accuracies will not be maintained when PU settings are set outside the setting range.
PU HMI Screen Example
PU Command
Purpose:
Read or change fault detector pickup levels
Syntax:
PU[x] [=<level>[,<cycles>]]
Comments:
x = 1 (fault detector 1), 2 (fault detector 2), or 3 (fault detector 3)
level = pickup level in amperes for fault detector x
cycles = number of moving average filter cycles
Cycles parameter is used only if an analog channel is programmed to have a moving average
filter (Lfx=type,2). See LF command information in
BESTlogic Functions section. An access
area one or two password is required to change settings.
PU Command Examples
1.
Set the analog channel pickup level at 6.2 amperes.
PU1=6.2
2.
Read the pickup setting for all channels.
PU
PU1=6.2; PU2=0.5; PU3=0.1,10
