CHA1 & CH2 turns on and the
safety outputs close).
Close the START contact: the
safety outputs close and the CH1 ,
CH2 LED turn on.
STEP 3 Release both input con-
tacts: the safety outputs open and
the CH1 , CH2 LED turn off.
During STEP 2 check that the
safety outputs do not close - with
manual START configuration - sim-
ply operating both input contacts,
without pushing the START
pushbutton.
STEP 4 (This step must be perfor-
med first on one input contact,
S11, then on the other one, S22
and only for 2-outputs ESPE).
Repeat the procedure from STEP
2, operating both input switches
(and START contact for manual
START configuration, so that the
safety outputs are closed), and
then releasing / disconnecting only
one of them and checking that the
safety outputs open: re-operate/re-
connect the input switch, push the
START button and check that the
safety outputs do not close.
The STEPS 3 and 4 must be
repeated for each input device
connected to the input terminals.
NOTE
During all steps verify that the
auxiliary output is closed when
the safety outputs are open and
that the auxiliary output is open
when the safety outputs are clo-
sed.
USAGE PRECAUTIONS
- The ESPE must be carefully
installed and positioned in order
to reach a high protection level
for the operator.
The European Standards state
the minimum distance between
the ESPE and the hazardous
area, in order to avoid the possi-
bility for the operator to reach
the hazardous area when the
conditions are still dangerous.
These distances depend on the
stopping time of the machine, on
the response time of the module
+ ESPE, on the resolution, on
the distance from the ground (for
horizontal mounting) of the
ESPE, and on the speed of the
operator approaching to the
dangerous area.
All plants must fully comply with
the requirements of the stan-
dards listed above and of all the
standards involved in each spe-
cific application.
- The safety module can check
the integrity of external contac-
tors or expansion modules sim-
ply connecting their NC control
contacts in series to the START
contact (or to the bridge, in auto-
matic START configuration) bet-
ween S33-S34 terminals.
- It is recommended to connect a
