Sensor Head Programming
Standard OMNI-BEAM sensor heads are field-programmable for four oper-
ating parameters. A set of four programming DIP switches is located at the base
of the sensor head (see photo at right), and is accessible with the sensor block
removed from the power block.
Switch #1
sensor design consideration which states that the amount of received light signal
required to operate the sensor's output is not the same as the amount required
to release the output. This differential prevents the sensing output from
"buzzing" or "chattering" when a light signal at or near the sensing threshold
level is detected.
Setting switch #1 to the "on" position programs the sensor head for "normal"
hysteresis. The NORMAL setting should be used always, except for low-
contrast situations like the detection of subtle differences in reflectivity. NOTE:
the "low" hysteresis setting (switch #1 "off") should be used only when all
sensing conditions remain completely stable.
Switch #2
open (i. e., it conducts with an alarm). Turning switch #2 "off" programs the alarm output for normally
closed operation (i.e., the output opens during an alarm).
The normally closed mode (switch #2 "off") is recommended. This allows a system controller to
recognize a sensor power loss or an open sensor output as an alarm condition. The normally open alarm
mode (switch #2 "on") should be used when the alarm outputs of multiple Standard OMNI-BEAMs are
wired in parallel to a common alarm or alarm input.
Switch #3
load output will energize (after a time delay, if timing logic is employed) when the received light level is greater than the sensing threshold
(i.e., when five or more D.A.T.A. lights are illuminated). In DARK operate, the output will energize (after a time delay, if any) when the received
light level is less than the sensing threshold (i.e., when four or less D.A.T.A. lights are illuminated).
For example, when sensing in a beam-break mode like opposed or retroreflective:
Similarly, when using a reflective sensing mode like diffuse (proximity) or convergent-beam:
Switch #4
array. This switch should always be in the "off" position, except for close differential sensing situations, like some color registration
applications, which also require the LOW hysteresis setting (switch #1 "off").
Standard OMNI-BEAM Sensor Heads
Factory settings:
The following are the factory program settings for OMNI-BEAM sensor heads.
1) The DARK operate mode would be used to energize the OMNI-BEAM's output whenever an object is present, and blocking the beam.
2) The LIGHT operate mode would be used to energize the output whenever the beam is unblocked (i.e., object missing).
1) The LIGHT operate mode would be used to energize the OMNI-BEAM's output whenever an object is present in front of the sensor,
2) The DARK operate mode would be used to energize the output whenever the reflection is lost (i.e., object missing).

Standard OMNI-BEAM sensor head modules are available in all photoelectric
sensing modes: opposed, retroreflective, diffuse (proximity), convergent-
beam, and fiber optic (both glass and plastic). They offer the same outstanding
optical performance as established by Banner's MULTI-BEAM and MAXI-
BEAM sensor families.
Construction: Standard OMNI-BEAM sensor heads are molded from rugged
VALOX
performance in demanding applications. The top view window is LEXAN
polycarbonate. Lenses are acrylic. Hardware is stainless steel. When
assembled, all parts are fully gasketed. Standard OMNI-BEAM sensor heads
are rated NEMA 1, 2, 3, 3S, 4, 12, and 13.
Operating Temperature Range: -40 to +70 C (-40 to +158 F).
Delay upon Power-up: 200 milliseconds maximum (power block outputs are
non-conducting during this time)
