Section 1 Description
B-3
1-2-3 Auxiliary Output
The signal of this output is the reverse signal of the
safety outputs (Dark-ON output). This output can be
used for monitoring purposes by connecting it to a device
such as a PLC.
1-2-4 EDM (External device monitoring)
This function makes it possible it monitor the state of the NC contacts of the MPCEs
(*1)
, so that a malfunction
of a MPCE, such as a welded contact, can be detected. Connect
(*2)
the NC contact of the MPCEs to the EDM
input line of the receiver. If the correct logical relationship between the OSSD outputs and the EDM input is
not kept, the light curtain immediately enters the lockout condition and the OSSD outputs will go to their
OFF-state. The light curtain’s normal operation is up to 300ms max. , this allows for the delay time caused by
the release of the MPCEs. To ensure the correct usage of this function, the MPCEs must be safety-approved
types with forcibly-guided contacts.
[When the EDM is not used]
In the case the EDM input is not used, connect the auxiliary output to the EDM input line.
*1. MPCEs (Machine Primary Control Elements) are usually relays or contactors used to control hazardous
movement directly.
*2. Connect the wires such that 24VDC (9VDC to Vs, nominal 24VDC) is applied to the EDM input via the series
connected NC contacts (Refer to 2-4 Wiring).

Total length of the light curtain
[Beam centre-line mark]
The two lines marked at the centre of the cap indicate the centre of the beam (See the figure shown below).
This position is a reference line for measuring safety distance. Use the line closer to the hazardous area as
a reference line for the safety distance.
