b) SAFE ILL
The emergency stop relay SAFE ILL can be used for:
ƒ
Single or dual channel capability for presence sensing safeguarding devices (light curtains and light
barriers).

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, it 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 terminals S33 and S34 must be bridged with a start button.
Afterwards the contact 13-14 is closed and the segment circuit is switched on. The LEDs 1, 2 and US
light up.
If the input set is opened, the safety contacts 13-14 are open and the LEDs 1, 2 and US turn off. The
following segment circuit of the Inline system is safety-related switched off.
The device is activated again, if the input sets close and the start button is pressed. The LEDs 1, 2 and
US light up again.
Over the interface to the Interbus Inline local bus the device status can be transferred.
The main circuit is interrupted in the device SAFE ILL.
