Entry Zone
3.8.1
1.
Use Smart 1 (a PNP input called a request) to notify the
control that there is a parcel ready for input to the zone. If
the zone is not already occupied, when this signal is active, it
will cause the zone to run. The signal may be provided by
any number of alternative sources such as a PLC, a simple
switch, a photo sensor, etc. as long as the input voltage is
positive and between 18 volts and 29 volts DC.
2.
Use Smart 2 (a PNP output called permission) to notify an
external device that the zone is empty and ready to receive a
parcel.
3.
Use Slug (a PNP input) to override all logic internal to the
control and force this zone to run regardless of whether it is
occupied or empty.
NOTE: When this signal is active, parcels are pushed into
the next downstream zone even if it is already occupied.
4.
Use Rev Slug (a PNP input) in one of two ways:
Alone: Assert it by itself to cause the zone to coast. The
motor will not be energized and will not provide any
active braking power.
In Combination: Assert it in combination with the Slug
input to override all logic internal to the control and force
this zone to run in the reverse direction regardless of
whether it is occupied or empty.
NOTE: When this signal is active, parcels are pushed out
of the upstream end of the zone regardless of the
availability of any upstream device to accept the parcel.
In this scenario, if there is nothing there, any parcels
could potentially fall to the floor.
5.
Use Analog In+ and Analog In- in combination to provide a
0-10 V differential signal that overrides the settings on the
speed control switch. If the voltage differential is less than
0.5 VDC, the control ignores the input and the speed control
switch settings will prevail. If the signal is 9.5 VDC or higher,
the control operates the motor at its maximum speed
setting of 280 or 350 RPM depending on the motor selected.
Intermediate Zone
3.8.2
An intermediate zone is between two adjacent SCC-3
controlled zones.
NOTE: Do not connect anything to Smart Input 1 or
Smart Output 2.
1.
Use Slug (a PNP input) to override all logic internal to the
control and force this zone and all adjacent upstream zones
to run regardless of whether they are occupied or empty.
Note that when this signal is active parcels will be pushed
into the next downstream zone even if it is already occupied.
2.
Use Rev Slug (a PNP input) in one of two ways:
Alone: Assert it by itself to cause this zone and all adjacent
upstream zones to coast. The motor will not be energized
and will not provide any active braking power.
In Combination: Assert it in combination with the Slug
input to override all logic internal to the control and force
this zone and all adjacent upstream zones to run in the
reverse direction regardless of whether they are occupied
or empty.
NOTE: When this signal is active, parcels are pushed out
of the upstream end of the conveyor regardless of the
availability of any upstream device to accept the parcels.
In this scenario, if there is nothing there, any parcels
could potentially fall to the floor.
3.
Use Analog In+ and Analog In- in combination to provide a
0-10 V differential signal that overrides the settings on the
speed control switch. If the voltage differential is less than
0.5 VDC, the control ignores the input and the speed control
switch settings will prevail. If the signal is 9.5 VDC or higher,
the control operates the motor at its maximum speed
setting of 280 or 350 RPM depending on the motor selected.
Exit Zone
3.8.3
1.
Use Smart 1 (a PNP input called permission) to notify the
control that it has permission to discharge a parcel. The
signal may be provided by any number of alternative sources
such as a PLC, a simple switch, a photo sensor, etc. as long as
the input voltage is positive and between 18 volts and 29
volts DC. Note that when permission is removed the zone
will attempt to stop any discharge that may be in process.
2.
Use Smart 2 (a PNP output called request) to notify an
external device that the zone is occupied and ready to
discharge a parcel.
3.
Use Slug (a PNP input) to override all logic internal to the
control and force this zone and all upstream zones to run
regardless of whether they are occupied or empty.
NOTE: When this signal is active, parcels will be pushed
off the end of the conveyor if there is nothing in place to
receive them.
4.
Use Rev Slug (a PNP input) in one of two ways:
Alone: Assert it by itself to cause the zone and all
upstream zones to coast. The motors will not be
energized and will not provide any active braking power.

could potentially fall to the floor.

speed setting of 280 or 350 RPM depending on the motor
selected.
