Safety gates and E-stop (switch 1 in position 4)
With switch 10 the maximum number of gates is selected. Open (unused)
inputs (S_1/S_2 and S_3/S_4) have to be linked with a wire bridge.
K1 and K2 can only be activated, if the e-stop loop is closed and all con-
nected gates have been opened and closed again.
Both gate contacts have to be operated within 3 s. If the time difference is
longer, the gate has to be opened before it can be closed again. When all
gates are closed the unit can also be activated by an external connected
simulation button.
After e-stop or power failure the unit can only be reset by manual start.
If changeover contacts are used on the gate switches the switchover time
has to be less then 50 ms. If it is longer the outputs K1 and K2 are switched
off and the unit gives failure code 7. This failure is stored and can only be
reset by disconnecting the auxiliary supply.
