Intermediate Zone
3.8.2
An intermediate zone is between two adjacent controlled
zones.
NOTE: Do not connect anything to the Smart 1 Input
or the Smart 2 Output in an Intermediate Zone
Exit Zone
3.8.3
1.
Use Smart 1 Input (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 above 18 volts when active.
Note that when permission is removed the zone will attempt
to stop any discharge that may be in process.
2.
Use Smart 2 Output (a PNP output called request) to notify
an external device that the zone is occupied and ready to
discharge a parcel.
Slug & Reverse Slug Input Operation
3.8.4
1.
Use Slug Mode (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.
Mode is sometimes referred to as Jog
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.
2.
Use Reverse 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.
§ In Combination: Assert it in combination with the Slug
Mode input to override all logic internal to the control and
force this zone and all upstream zones to run in the
reverse direction regardless of whether they are occupied
or empty.
Analog Speed Control Input
3.8.5
Use the control's Analog In+ and Analog In- inputs in
combination to provide a 0-10 V differential signal that
overrides the settings of the speed control DIP switch.
If the voltage differential is less than 0.5 VDC, the
control ignores the analog input and the control's DIP
switch speed settings will prevail.
If the signal is 9.5 VDC or higher, the control operates
the motor at its maximum speed setting.
Automation Controls Group has available a manual
Analog Speed Control Module (ACG P/N 300128) for
use with this control for manually setting the same
motor speed on up to 10 zones.
To provide the required differential Analog Speed
Input voltage using a PLC, the PLC Analog Output
Module you select should be able source and sink a
minimum of 20mA.
