WARNING These photoelectric presence sensors do NOT include the self-checking redundant circuitry necessary to allow
their use in personnel safety applications. A sensor failure or malfunction can result in either an energized or a de-energized sensor
output condition.
Never use these products as sensing devices for personnel protection. Their use as a safety device may create an unsafe condition
which could lead to serious injury or death.

Systems, and other systems so
designated, are designed to meet OSHA and ANSI machine safety standards for point-of-operation guarding devices. No other Banner sensors or
controls are designed to meet these standards, and they must NOT be used as sensing devices for personnel protection.
1) Attach two individual fiber optic assemblies (or one bifurcated
fiber optic assembly) to the D12DAB6 Series sensor, using the
instructions packed with the fiber. Mount and align the sensing end(s)
of the fiber(s) at the sensing location in a position that will optimize the
differential between the "light" and "dark" conditions.
2) Do not connect the load at this time: the LOAD (yellow) LED will
simulate the action of the load. Connect the brown and blue wires from
the sensor to a +10 to 30V dc source (see hookup diagram, right).
Apply dc power and verify that the POWER ON LED (green) is "on".
3) Set the LO/DO switch to DO (dark operate). Present the "light"
condition to the sensor. Make sure that the LOCK LED (red) stays
"on". If necessary, adjust the fiber ends so that the red LOCK LED
stays "on" reliably.
NOTE: If the "light" condition is a quick transition that cannot be
simulated as a static condition and the "dark" condition is the normal
condition, set the LO/DO switch to LO (light operate). Adjust the fiber
ends so that, when the "light" condition occurs, the yellow LOAD
indicator LED comes "on" reliably.
4) Simulate the sensing event to the sensor while observing the amber
LOAD LED. If necessary, adjust the GAIN control (clockwise to
increase) so that the LOAD LED changes state positively and reliably
to all desired variations of the sensing event. Note that too much gain
may result in unwanted response to conditions such as vibration of the
sensing ends, etc.
5) While observing the LOAD LED, adjust the output pulse length
using the sensor's 3/4-turn HOLD control. Minimum "on" time is 1
millisecond; maximum "on" time is 70 milliseconds.
6) Connect the load to the sensor and check the system.

NOTE: These sensors will operate normally if the supply voltage polarity is reversed;
however, the white and black wires must always be wired as shown above.
