5.2 Connection Example, for connection to safety relay
There are alternative possibilities for reset (see the following examples):
A Automatic reset: The safety relay is connected for automatic reset and terminal
1 (white cable) on the receiver is connected to 24VDC.
B Manual Reset from relay: The safety relay is connected for Manual reset and terminal 1
on the receiver (white cable) is connected to 24VDC
C Manual Reset from Light Barrier: The safety relay is connected for automatic reset and terminal
1 (white cable) on the receiver is connected to one side of a
push button (NC) and the other side is connected to 24VDC.
Switches 8 is set in “ON” position as default from factory connection examples (see 4.4). If example c is
required then Switch 8 must be set to “OFF”. If test/reset  is also connected it may be used for other
functions (see 2). The LMS indicator L1 signals opened barrier or safety relay.
NB! If test/reset  is not connected, the white wire must be connected to 24VDC. If test/reset  and  are
pressed and are released at the same time, no reset occurs.
NB! The connections in the drawing above which are marked with bold lines should only be made if the
muting function is to be used.
