6.8 Safety control
Interruption of power supply during demagnetization pulse leads to immediate pulse
disruption.
•
Parts in the vicinity of the coil are magnetised and need to be demagnetised
once more
•
Frequent interruption accelerates electric wear
The main switch (red/yellow) is an emergency stop button. Energy supply is immediately
terminated (Safe stop 0).
Interruption of the
External enable signal
(see chapter
D-Sub15 Control Interface
) makes
triggering a demagnetization pulse impossible. An already running pulse is completed. The
energy supply is not terminated.
6.8.1 Safe Torque Off (STO), Optional
For integration in a centralized safety control, the DN power module can be equipped with an
interface. Applications:
•
Safety guard with/without guard control
•
Mushroom pushbutton
•
Safety light curtain
Triggering the STO leads to a Safe Stop category 1.
