Mode 3: Rear area excluded
Backgauges near the dies.
Warning :
This function must be used only when necessary for the type of work
to execute. The employer is then responsible to check the correct
use of the function and to forbid the abuse of it.
In some cases, the backgauges could intercept the rear protection area causing the stop of
the press, even if the operator remains outside the dangerous area. To avoid this situation
and protect the operator, the operating mode 3 can be set.
Fig. 10.3 Operating mode 3: rear area inhibited
The operating conditions are identical to those of mode 1 with the only difference that the
rear area is excluded.
The central and front protection areas are active, the obscuration of any receiving element
of these areas causes the state OFF of the OSSD outputs and the consequent stop of the
downstroke of the press-brake. For the operation of the machine, the consideration made
for the operating mode 1 are valid.
Residual risk :
In this operating mode, part of the detection field is inhibited. It is
then necessary that the operator is informed about the residual
possibility of squashing between the punch and the die or between
the punch and the piece in work.
In order to minimize the dangerous area, it is appropriate that the
length of the tools is the minimum necessary for the current
processing.
