Sensor Hookup Diagrams for CM Series MAXI-AMP Modules

NOTE REGARDING CABLE SPLICING:

When splicing additional cable length to modulated remote sensors,
it is important to use a separate shielded cable for emitter and
receiver wires. Combining emitter and receiver wires together in
the same cable (even if the cable is shielded) will result in direct
coupling of the emitter signal to the receiver leads. This is called
"cable crosstalk", and will not allow full amplifier sensitivity setting
without an amplifier "lock on" situation, which appears as a continu-
ous LIGHT condition. Banner offers extension cable for remote
sensors which, if used for cable splicing, will minimize the chances
for cable crosstalk (see page 24).

The AUXILIARY terminal (#9) of CM3 models offers a
logic-level NPN (current sinking) output which may be used
as a fast-response solid-state inhibit signal to the AUXIL-
IARY input of MAXI-AMP CM5 modules. This output may
also serve as an input to any B Series, Plug Logic, or CL
Series 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 LR & PT400 sensors and
a CM3 module to provide inspection information, with the
SP300D functioning as a product sensor. Typically, the
CM5 module would be programmed for the ONE-SHOT or
DELAYED ONE-SHOT logic function. If the LR & PT400
"sees" an acceptable condition when the SP300D senses the
leading (or trailing) edge of a product, the CM3 will inhibit
a reject pulse from occuring.

External 10 to 30V dc devices such as self-contained sensors
may be connected between terminals #3 (+) and #1 (-) of any
CM series MAXI-AMP module. Terminal #3 offers 40mA
maximum. This is sufficient to power most Banner self-
contained dc sensors.

As the example at the right illustrates, 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 CM5 module.
