Banner PT Remote Sensors - Manual (Page 2)

When wiring two sensors to one
MAXI-AMP, multiply excess gain
data (from excess gain curve) for
each sensor by 1/2; when wiring
three sensors to one MAXI-AMP,
multiply excess gain by 1/3.
MAXIMUM SENSOR LEAD LENGTH: 30' (9m).
POWER SUPPLY REQUIREMENT: 10-30V dc at less than 20mA; 10% maximum
ripple (obtainable from MPS-15 power supply--see above).
OUTPUT CONFIGURATION: model MA3-4 has two open-collector NPN (cur-
rent sinking) transistor solid state switches, one normally open, one normally closed.
150mA max. each output. Model MA3-4P has two PNP (sourcing) outputs, 150mA
max. each.
RESPONSE SPEED: 1 millisecond ON and OFF.
OPERATING TEMPERATURE RANGE:
-40 to +70 degrees C (-40 to +158 degrees F).
Hookup to MICRO-AMP ® Modules
MICRO-AMP amplifier module models MA3-4 and MA3-4P may
be used with this sensor. Model MA3-4 has complementary current
sinking outputs. Model MA3-4P has complementary current sourc-
ing outputs.
Model MA3-4 (but not model MA3-4P) may be powered by the model
MPS-15 power supply, as shown in the hookup diagram (right). The
MPS-15 includes a socket for the MA3-4 and has a built-in SPDT
output relay (switchable by the MA3-4 module).
MICRO-AMP modules may also be mounted in a model RS8 wiring
socket and powered from a "remote" power supply. PVC mounting
track is available in 6" and 12" lengths to accommodate multiple MI-
CRO-AMP system components.
NOTE: only one SP300L may be connected to each amplifier.
Specifications, MAXI-AMP CM Series Modules
RESPONSE SPEED: programmable for 10, 2, or 0.3 milliseconds (10 millisecond setting enhances noise rejection).
MAXIMUM SENSOR LEAD LENGTH: 50' (15m) maximum.
To avoid "cable crosstalk", use separate shielded cable for emitter and receiver, or order sensors with extended cable length.
OPERATING TEMPERATURE RANGE: 0 to +50 degrees C (+32 to +122 degrees F).
To a Single Sensor
"light") or dark-operated AND logic (input to module occurs when all
receivers simultaneously see "dark") is possible.
CM Series modules combine power supply, modulated photoelectric
amplifier, timing logic (CM5 models), and output relay in a single
compact module. Only an 11-pin relay socket (Banner model RS-11)
is needed to complete the system.
The CM Series contains models with or without programmable timing
logic and with either electromechanical or solid-state relay outputs. See
the Banner product catalog for further information.
Up to three sensors may be connected to each amplifier. Light- operated
OR logic (input to module occurs whenever at least one receiver sees
NOTE: to power the MAXI-AMP from a DC power supply, connect
+12 to 28V dc at ≥70mA to terminal #3 and DC common to terminal
#1. Make no connections to terminal #7 or #8.

WARNING
These photoelectric presence sensors and amplifiers do NOT include the self-checking redundant circuitry necessary
to allow their use in personnel safety applications. A sensor or amplifier 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 safety devices may create an unsafe condition which
could lead to serious injury or death.
Only MACHINE-GUARD and PERIMETER-GUARD 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.
