Assembly and function
S11,S12,S21,S22,S33,S34,S41,S42 S51,S52 Activation- and release contacts
UM-US, 13-14 Safety current circuit (normally open contact)
The activation and input contacts have to be wired according to the intended purpose (s. of " sample
applications " and " assembly and line-up "). For the operation of the device the device must be
connected with the Inline system. Over the Inline bus terminal or a power terminal the voltage supply of
24V/DC is taken over. It lights up the LED "UM".
For the start the terminal S33 with S34 must be bridged with a start button.
Afterwards the contact 13-14 is closed and the segment circuit is switched on. The LED's 1,2 and US
lights up.
If the input set is opened, the safety contacts 13-14 are open and the LED's 1, 2 and US goes out. The
following segment circuit of the Inline system is safety-reality switched off
The device is again activated, if the input sets close and the start button is pressed. The LED's 1 and 2
and US lights up again.
Over the interface to the Interbus Inline local bus can be transferred the device status.
The main circuit is interrupted in the device SAFE IL1.
