6.7 CURRENT OFF-LIMIT
ACTION
Command
Overload Action
OLO
Cutout. The SI
1287 goes to the "standby” state and the cell
current is cut off completely.
OL1
Limit. The cell current limits at
the
full-scale value
of a
fixed
range (or the I LIMIT value).
OL2 No
Limit. The cell current is uncontrolled and
may rise to
>±2A.
Caution: Some cells may
be
damaged
by an
excessive current
flow.
