Mute Output
An external electronic mute output signal is available from the Grey wire on the
Transmitter (TX) head cable, mute ON = 24 V DC (500mA maximum) and mute
OFF = 0 V DC. This can be used to drive an external relay for remote indication
via a beacon and/or an input to a PLC.
A LED indicator located at the top of the Transmitter (TX) head labelled as MUT
(light curtain Muted or Partial Muted) shows the status.
Status Output
The status output is a NON-SAFETY output and should only be used for non-
safety applications. E.g. connecting an indicator lamp or as feedback to a PLC.
The status output is used to confirm that the safety light curtain has reset and the
safety outputs (OSSDs) are ON.
The status output, Pink wire on the Transmitter (TX) head cable, energises when
the safety outputs (OSSDs) = ON and de-energises when the safety outputs
(OSSDs) = OFF. Status output energised = 24V DC (500mA maximum) and de-
energised = 0V DC.
STAT LED on the Transmitter (TX) head will turn on to indicate that the light
curtain is aligned correctly.
Communication Link
The Transmitter (TX) and Receiver (RX) heads communicate via RS232. The
Blue wire from the Transmitter (TX) head cable must be connected to the Blue
wire from the Receiver (RX) head cable.
The Red wire from the Transmitter (TX) head cable must be connected to the Red
wire from the Receiver (RX) head cable.
Warning The Data wires R IN and T OUT are communication links
at RS232 voltage levels (+/-9V). They MUST NOT be connected to any
other voltage source.
The maximum total cable length from the Transmitter (TX) head to the
Receiver (RX) head must not exceed 40m.
MUT - Yellow LED ON = Mute ON Yellow LED OFF = Mute OFF
STAT - Green LED ON = Status ON Green LED OFF = Status OFF
