Banner VALU-BEAM Series - Manual (Page 14)

VALU-BEAM 990 Series sensors boast the same high optical
performance offered by the front-line 912 Series, and also
contain a built-in 6-digit totalizing counter. Sensor models are
available for opposed, retroreflective, and convergent beam
sensing modes. In addition, there are models for use with both
glass and plastic fiberoptics.
A special infrared retroreflective version is available, which is
designed for counting people passing through entry ways. It has
built-in on/off time delays to minimize the chance of multiple
counts.
The 990 Series VALU-BEAM's 6-digit LCD counter is reset
simply by touching the area of the housing shown with the
permanent magnet supplied with the sensor (see dimension
drawing, below). Standard models automatically reset to zero
upon power-up.
Memory backup option: SMA990 Series sensors with internal memory backup for maintaining "count memory" while power is
removed are available by special order. These models will "hold" a count for over 100 hours, and are indicated by the model number
suffix MB (i.e., "SMA990LVMB" is the memory backup version of sensor model SMA990LV). Contact the factory for availibility
and pricing of these models.
SMA990 Series sensors wire directly to either 10 to 250V ac (50/60Hz) or 12 to 115V dc.

SUPPLY VOLTAGE: 10 to 250V ac, 50/60Hz or 12 to 115V
dc at less than 20 milliamps.
SENSOR RESPONSE: 15 milliseconds LIGHT, 15 millisec-
onds DARK (except SMA990LT, page 16). 100 millisecond
delay on power up (no counts are entered during this time).
Models with memory backup have no power-up delay. Note:
Some models with memory backup may increment 1 count upon
reapplication of power.
COUNT ENTRY: counts are entered on DARK-to-LIGHT
transition.
COUNT RESET: in standard models, counter is reset to zero
automatically upon applying power to the sensor. All models
may be reset by touching the housing on top of the sensor (see
below) with a permanent magnet (supplied with sensor).
CONSTRUCTION: reinforced black VALOX ® housing, to-
tally encapsulated circuitry, molded o-ring sealed lenses or fiber
fittings, stainless steel hardware. Meets NEMA standards 1, 2,
3, 3S, 4, 4X, 12, and 13.
CABLE: 6 feet (2m) of PVC-jacketed 2-conductor cable is
standard. Three-pin quick-disconnect ("QD") models are avail-
able optionally (one conductor goes unused). Order model
MBCC-312 3-conductor cable for "QD" models (page 18).
INDICATOR LED: top-mounted red LED indicator lights
whenever the sensor "sees" its modulated light source.
OPERATING TEMPERATURE RANGE: 0 to 50 degrees C
(32 to 122 degrees F).
