Wiring - Delta CS2 Technical Information

Wiring

The CS2 is designed to be wired using watertight flexible plastic conduit. In applications where sealed operation is
unnecessary, the wires can be run out through a strain relief connector. The conduit can also be used to pressurize the CS2
with low pressure, dry air for additional protection.
The number and type of wires required depend on the mode of operation. Only two wires, for 24Vdc power, are required to
operate the device. In simple applications, two more wires are used for the output. A four wire cable with an overall shield is
fine.
If analog threshold inputs or color outputs are used they need to be run through individually twisted, shielded pairs.
General Wiring Guidelines
1. The CS2 has sensitive circuitry which can be affected by electrical noise generated by loads. Its power supply should not
be used to power other loads.
2. The output of the 24Vdc sensor power supply must be isolated from earth ground. The CS2's common is connected to
earth ground through its case.

CS2 Color Scanner
In this application, the
CS2 is used in its
default configuration
(internal trigger, darker
areas to be sorted or
rejected, object scanned
every 500uS). In order
to activate the solid-
state-relay (SSR), the
object in the scanning
area must cause the
Base color to exceed
the Base Threshold
(object present) and the
Sense color must be
below the Sense
Threshold (Low Ratio).
