6.1 Tightening cell
A tightening cell is defined as the installed
hardware for at least one tightening channel
and at least one data interface for communi-
cation with the operating or evaluation pro-
gram or the superior controller. This includes
the corresponding tightening programs and
tightening applications.
form
A tightening channel is controlled by an
24 V
SEH312 tightening controller. The KE310 or
KE312 and SEH312 communicate with each
24 V
other via an internal bus system.
+/–
Up to 48 tightening programs can be stored
10 V
in a tightening controller. Only 1 tightening
Refere
program can be started at a time.

6.2 Control signals
+/–
The tightening cell communicates with the
10 V
superior controller via control signals. A PLC
24 V
assignment table determines which control
24 V
signals are assigned to the inputs/outputs.
The inputs/outputs are assigned in the
0 V
BS300 operating program.
For more information, refer to:

– the online guide in the operating program
(programming the assignment table),
