CURRENT OFFSET EXAMPLES
CURRENT OFFSET is disabled. The CURRENT cannot be changed
in OPERATE mode.
CURRENT OFFSET is +/-5%. For SINGLE DISPLAYED
SCHEDULE, the CURRENT can be changed in OPERATE mode
within 10% window; i.e., up to +/-5% from original BASE value
programmed in PROGRAM mode.
For example: For an original BASE CURRENT value of 70%,
a new value may be from 65% to 75%.
CURRENT OFFSET is +/-5%. For ALL SCHEDULES, the
CURRENT can be changed in OPERATE mode within 10%
window; i.e., up to +/-5% from original BASE value programmed
in PROGRAM mode.
For example: For an original BASE CURRENT value of 70%,
a new value may be from 65% to 75%.
CURRENT OFFSET is +/-5%. For SINGLE DISPLAYED
SCHEDULE, the CURRENT can be changed in OPERATE mode
within 10% of maximum RMS CURRENT window; i.e., up to
+/-5% from original value programmed in PROGRAM mode.
For example: For an original BASE CURRENT value of 14.00 kA
and maximum RMS is 20.00 kA, a new value may be
from 13.00 kA to 15.00 kA (because 5% of 20.00 kA
is 01.00 kA).

CURRENT OFFSET INDICATION
In the PROGRAM mode, when the PERCENT CURRENT is displayed, the control will flash if
the CURRENT OFFSET is active. The programmed BASE CURRENT is indicated
simultaneously with the schedule number. The OFFSET CURRENT is indicated simultaneously
with
C.O.C.O.
C.O.C.O.
C.O. in the SCHEDULE display plus either
S.S.
S.S.
S. (Single Displayed) or
A.A.
A.A.
A. (All) in the DATA
display (NON-CONSTANT CURRENT mode) along with the OFFSET CURRENT value used.
The ENTER push button can be depressed while either of the two values are displayed. Pressing
ENTER will move the OFFSET CURRENT value into the BASE PERCENT CURRENT value.
BASE CURRENT value also may be changed by pressing or holding DATA push buttons and
then pressing ENTER.
