OMNI-BEAM Sensor Heads
DIP Switch Settings
OMNI-BEAM sensor heads are field-programmable for four operating parameters. To
access the four programming DIP switches (see figure 5), remove the sensor block
from the power block.
Switch #1, Sensing Hysteresis
ON: Standard hysteresis.
OFF: Low hysteresis; should be used only when all sensing conditions remain
Hysteresis is an electronic sensor requirement that the amount of received light
needed to energize the sensor’s output not be equal to the amount needed to release
the output. This differential prevents the sensing output from “buzzing” or
“chattering” when the received light signal is at or near the sensing threshold level.
The standard setting should be used always, except for low-contrast applications
such as the detection of subtle differences in reflectivity.
Switch #2, Alarm Output Configuration
ON: Alarm output is normally open (it conducts with an alarm).
OFF: Alarm output is normally closed (the output opens during an alarm).
Normally closed mode (OFF) is recommended; it allows a system controller to
recognize a sensor power loss or an open sensor output as an alarm condition.
Normally open alarm mode (ON) should be used when the alarm outputs of multiple
OMNI-BEAMs are wired in parallel to a common alarm or alarm input.
Switch #3, Light or Dark Operate
ON: Dark Operate mode; the output energizes (after a time delay, if applicable) when
OFF: Light Operate mode; the sensor’s load output energizes (after a time delay, if
Switch #4, Scale Factor for the D.A.T.A. Signal Strength Indicator Display
ON: Fine scale.
OFF: Standard scale.
This switch should always be OFF, except for close differential sensing situations (for
example, some color registration applications, which also require the Low hysteresis
setting/switch #1 OFF).
Factory Settings
The following are the factory program settings for OMNI-BEAM sensor head DIP
switches.
Switch #1: ON (Standard hysteresis)
Switch #2: OFF (Normally Closed alarm output)
Switch #3: OFF (Light Operate load output)
Switch #4: OFF (Standard Scale Factor for signal strength display)
