3.2 EOB Zone Configuration
3.2.1 Controlling Object Entry – Forward (normal) Flow Direction
Use Smart I/O Pin 4 (Forward Request/Reverse Permission In) to notify the control that there is a package ready for
input to the zone. If the zone is empty 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 photoeye sensor, etc.
Use Smart I/O Pin 5 (Forward Permission/Reverse Request Out) to notify an external device that the zone is empty and
ready to receive a package.
3.3 Master Zone Configuration
3.3.1 Controlling Object Exit
Use Smart I/O Pin 4 (Forward Permission/Reverse Request In) to notify the zone that it has permission to discharge a
package. The signal may be provided by any number of alternative sources such as a PLC, a simple switch, a photoeye
sensor, etc.
NOTE: When permission is removed the zone will attempt to stop any discharge that may be in process.
Use Smart I/O Pin 5 (Forward Request/Reverse Permission Out) to notify an external device that the zone is occupied
and ready to discharge a package.
Use Smart I/O Pin 6 (Branch No-Fault Out) to provide an indication of a fault in the Branch when this output goes
inactive.
3.3.2 Changing Operational Modes
The default Operational Mode for the Branch is Singulate. Smart I/O Pins 1 and 2 on the Master Smart I/O
Connection Header provide other Operational Modes as listed in Table 5: Smart I/O Pin Definitions for the Master
Zone Controller in Basic Mode.
3.3.3 Controlling Branch Direction
Use Smart I/O Pin 3 on the Master (Branch Reverse In) to reverse the flow direction of the Branch. Reverse mode
requires an additional photoeye sensor connected to the Secondary Sensor input (see Section 2.2: Zone Installation).
3.3.4 Controlling Branch Speed
Use Speed In (0-10VDC) on the Master to control the speed of the Branch. See Table 7: Speed Input Analog Control.
3.4 Basic Mode Parameters
The following are the parameters available in Basic Mode:
