Power for external devices Logic level NPN output, CR3 models
The AUXILIARY terminal (#9) of models CR3(R)A and CR3(R)B offers a
logic-level NPN (current sinking) output which may be used as a fast-response
solid-state inhibit signal to the AUXILIARY input of MAXI-AMP CR5 Series
modules. This output may also serve as an input to any B Series or Plug Logic
module. In addition, this output may interface to other dc devices or circuits
like counters, rate meters, or programmable logic controllers. Switching
capacity is 20mA at 12V dc.
The example here shows the use of an SP100C sensor and a CR3 module
to provide inspection information, with the SP100E/R pair functioning as
a product sensor. Typically, the CR5 module would be programmed for
the ONE-SHOT or DELAYED ONE-SHOT logic function. If the SP100C
"sees" an acceptable condition when the SP100E/R pair senses the leading
(or trailing) edge of a product, the CR3 will
inhibit a reject pulse from occuring.

External 10 to 30V dc devices such as self-contained sensors may be con-
nected between terminals #3 (+) and #1 (-) of any CR Series MAXI-AMP
module. Terminal #3 offers 40mA maximum. This is sufficient to power
most Banner self-contained dc sensors.
In the example below, the current sinking output of a self-contained sensor
powered by the MAXI-AMP may be used as the input to the AUXILIARY
terminal of a CR5 module.
The example shows the use of an SE612 ECONO-BEAM sensor to provide
inspection information, with the SP100E/R pair functioning as a product sen-
sor. Typically, the CR5 module would be programmed for the ONE-SHOT
or DELAYED ONE-SHOT logic function. If the SE612 "sees" an acceptable
condition when the SP100E/R pair senses the leading (or trailing) edge of a
product, it will inhibit a reject pulse
from occuring.
Hookup to multiple sensors
Up to three miniature remote sensors may be connected to any CR Series MAXI-AMP.
The emitter wires connect together in series to terminals #2 and #3. The receiver wires
connect in parallel to terminals #10 and #11. The yellow shield wires connect together
at terminal #1.
If the MAXI-AMP is programmed for LIGHT operate, the amplifier will initiate an
output or the timing logic if any receiver "sees" light. In the DARK operate mode, the
amplifier will output when all receivers "see" dark coincidently.
When multiple remote sensors share a common amplifier, the
range of each sensor decreases. When wiring two sensors to
one MAXI-AMP, multiply excess gain data for each sensor by
1/2 (obtain the data from the applicable excess gain curve).
When wiring three sensors to one MAXI-AMP, multiply
excess gain by 1/3.
