Function test
WARNING
Fatal injury due to faults during the function test.
Before carrying out the function test, make sure
f
that there are no persons in the danger zone.
Observe the valid accident prevention regula-
f
tions.
Check the device for correct function after installa-
tion and after every fault.
Proceed as follows:
Mechanical function test
The actuator must slide easily into the actuating
head. Close the guard several times to check the
function. The function of any manual releases (except
for the auxiliary release) must also be tested.
Electrical function test
1. Switch on operating voltage.
2. Close all guards and activate guard locking.
The machine must not start automatically.
¨
It must not be possible to open the guard.
¨
3. Start the machine function.
It must not be possible to release guard locking
¨
as long as the dangerous machine function is
active.
4. Stop the machine function and release guard
locking.
The guard must remain locked until there is no
¨
longer any risk of injury (e.g. due to movements
with overtravel).
It must not be possible to start the machine
¨
function as long as guard locking is released.
Repeat steps 2 - 4 for each guard.
