The modules should be inserted into the front
of the SE302 tightening controller and
should be screwed into place to ensure that
they are not removed by accident.
Before inserting the in-
terface modules, the
system boxes or
BT300 card rack must
be switched to neutral
and a discharging time
of ≥ 3 minutes must be
taken into account.

6 SE302 control signals
6.1 Tightening cell
A tightening cell is designated as the in-
stalled hardware for at least one tightening
channel and at least one data interface for
communication with the operating or evalua-
tion program or the superior controller. This
includes the corresponding tightening pro-
grams and tightening applications.
A tightening channel is controlled by a
SE302 tightening control unit. The KE300
and SE302 communicate with each other via
an internal bus system.
Up to 48 tightening programs can be stored
in a tightening controller. Only 1 tightening
program can be started at a time.
6.2 Control signals
The tightening cell communicates with the
superior controller via control signals. A PLC
assignment table determines which control
signals are assigned to the inputs/outputs.
The inputs/outputs are assigned in the
BS300 operating program.

(Programming the assignment table)

"Control signals" (3 609 929 918) (signal

chronological sequences).
