Conveyor Sensor Systems
E68 Series Integral Sensor Valve
Product Overview
High Reliability and Flexibility
ISV sensors are available in
both polarized reflex and
diffuse reflective sensing
modes. Polarized sensors
eliminate detection errors
caused by shiny targets and
provide the highest level of
high sensing reliability when
used at common conveyor
widths.
Diffuse reflective models can
be installed in low lift-height
locations and other areas on
the conveyor where it may
not be possible to mount a
polarized reflex sensor and
reflector. These models have
an extremely narrow field of
view to allow for mounting
below the level of the
conveyor rollers in certain
cases where necessary.
Choose a Sensor to Meet Your
Specific Needs
To provide an ideal solution
for a wide variety of Zero
Pressure Accumulation
needs, ISV sensors are
available in two different
embedded logic modes:
●
The Basic Logic Series
offers high-throughput
smart Zero Pressure
Accumulation control. This
logic results in singulation
and Zero Pressure
Accumulation. Each sensor
checks the status of the
downstream zone and
each zone always runs
except when both the
current and downstream
zones are full
●
The Progressive Logic
Series offers even higher
throughput than the Basic
Logic. This logic does not
singulate product, but does
result in Zero Pressure
Accumulation. Each zone
always runs until all of the
zones downstream are full,
allowing maximum
efficiency.
E68 Series System Components
Sensor
The ISV sensor has been
specially designed with
upstream communication
abilities and internal logic to
implement Zero Pressure
Accumulation (ZPA) control.
When combined with the
following components, a
complete ZPA conveyor
control system can be literally
snapped into place on your
conveyor. Two versions are
available depending upon the
control you require: Basic
Logic and Progressive Logic
(described on this page).
Sensor with Integrated
Beam Status Output
These ISV Sensors are the
same as standard units in all
respects, with the exception
of a special output connector
that is added to the sensor
body. This allows you to
conveniently access the
beam status output of any
zone by simply substituting a
special sensor of this type in
place of a standard unit. This
is useful, for example, at the
infeed end of a section of
conveyor where a lane full
signal is required, as a
separate photo-eye need not
be mounted.
Power Supply
A 4A Power Supply designed
for use with the Conveyor
Sensor systems. A single
power supply can normally
operate up to 50 zones. For
more information, see Page
V8-T6-28.
Power Supply Cable
This cable allows the power
supply to be connected to
any zone, while allowing use
of that zone.
Release Cable
This cable is normally
connected to the last zone
and is tied to your external
control to allow release of
product from the conveyor
system. The system can be
wired to the power supply to
enable either singulated
product release or slug/train
release from the conveyor’s
discharge end.
Buss Harness (Not required
with Daisy-chained models)
The Buss Harness distributes
power, slug release signals
and provides communications
links for Multi-drop versions
of the ISV. Made from flat
ribbon cable, it is available in
10, 50 and 100 ft lengths and
is connectorized at intervals
to match your zone length
(18 to 60 inches in 6 inch
increments). A buss link
accessory can be used to
join multiple sections
together, while a zone
jumper accessory may be
used to skip unused zones.
This harness is only required
for Multi-drop connection
versions of the ISV (described
on this page).
