Remedy
Check the noise status around this
device.
Replace this device.
Only pair up emitters and
receivers of the same type, i.e.
with the same number of beam
channels.
When the power is on, prevent any
extraneous light from entering the
receiver, if the extraneous light is
coming from other models see
"Device Placement" on page 22.
Wire the control output 1 (OSSD 1)
wire (black) and the control output
2 (OSSD 2) (white) correctly.
The current value for the control
outputs should be within the
specified range "Wiring" on page
34.
Wire the output polarity setting
wire (shield) correctly.
(0V: PNP, +V: NPN output)
Wire the output polarity setting
wire (shield) of the receiver
correctly "Wiring" on page 34.
The output circuit is damaged.
Replace this device.
Wire the wire output polarity
setting (shield) correctly.
