Safety Gates (switch 1 in position 3)
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. If gate
inputs are not used the type of control has to be with simulation button.
K1 and K2 can only be activated, if all connected 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.
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.
