The length of the connection cable between the control unit and transmitter or receiver must not exceed
50 m. The specifications for the connection cable are given in section 9.
If only one protective beam will be used, the second light barrier channel should be replaced by an appro-
priate jumper wire.

Message outputs
Three short-circuit-proof message outputs are available on the OSSD module for external displays to indi-
cate the status of the electrosensitive protection device at a suitable external location as well (Terminals 1
to 3).
Safety outputs
The OSSD relay outputs must be protected externally with fuses. All pnp outputs are protected against
short-circuit and do not require any external fuses.
With an inductive load of the relay output contacts, the latter must be protected against the increased load
that is thus generated by RC combination or freewheeling diodes. The circuitry must be wired directly to the
load.
Information
Light barrier to be replaced
When using freewheeling diodes, it should be noted that the pulse decay time of the connec-
ted relays or contactors is extended.
