FIGURE 7A
5. When carton #2 activates controller "B," Zone #2 stops driving. A signal is
sent to Zone #3 indicating that Zone #2 is occupied.
6. The above sequences are repeated until the conveyor is fully loaded.
UNLOADING THE CONVEYOR - SLUG MODE
1. Releasing all cartons is accomplished by "de-activating" the zone stop
signal to the discharge zone (Refer to the "Auxiliary Connections" section).
This causes all occupied zones to drive and restores power to the tread
rollers. All cartons then move forward (Figure 6B).
2. All cartons will continue to move forward without singulation as long as the
zone stop signal is de-activated.

MAINTENANCE

• EZLOGIC® CONTROL CONNECTIONS
Each zone controller has a built-in cable to provide a zone drive/no drive
output to the pressure roller module(s) for each zone. This cable is terminated
with a female Pico-style sealed snap-lock connector. Connection is made by
pushing the cable connector onto a connector tee cable. This connector fits into the
connector on the drive module. If there are more than one pressure roller modules
in a zone, an additional tee cable can be connected in series with the initial cable
to control the additional modules. When the drive board receives a "run" signal from
the EZLogic® zone controller, the drive module is actuated to apply force to the belt
to drive the tread rollers in a zone.
When the GEN3 NBEZ controller is used, power to the drive module and brake
are supplied through the controller. This only applies to the GEN3 NBEZ controller
shown in Figure 7B.
Please note that this output is only to be used to operate the zone mechanism
of the conveyor. It is not to be used as an output signal to other control
devises. If a control output is needed, an optional auxiliary I/O module should
be used. Please refer to the EZLogic® GEN3 Component Manual for more
information.
AUXILIARY CONNECTIONS
Every EZLogic® zone controller is equipped with an auxiliary port to accept
a zone stop signal, a slug input signal, or a zone wake-up signal by simply
connecting an auxiliary input cable to the auxiliary port of the controller and
then wiring the two wires of the cable to any "dry contact" type switching
device, such as a toggle switch or relay. No other components are required.
The default setting is for a zone stop signal. To use the signal for slug input
or zone wake-up, program the zone controller as detailed in the EZLogic®
GEN3 Component Manual.
NOTE: Do not apply a voltage to these wires, or wire more than one controller
to any one contact.
SLUG MODE CONNECTIONS
The EZLogic® accumulation system provides two modes of accumulation
which are user-selectable: Singulation mode and Slug mode. (For descriptions
of the sequence of operation for each mode, refer to the "Sequence of
Operation" section on pages #5 and #6. The desired mode of operation may
be programmed into the zone controllers at installation (refer to the EZLogic®
GEN3 Component Manual for details). If the user wishes to be able to
alternate between singulation mode and slug mode "on-the-fly," an optional
Auxiliary Input Cable (Hytrol P/N 032.563) may be used. The default mode is
singulation mode. If the user desires to operate the conveyor in slug mode, or
if the user wishes to be able to alternate between the two modes as needed,
the following procedures should be used.
SLUG MODE ONLY
Program the zone controllers to operate in "slug mode only" as detailed in the
EZLogic® GEN3 Component Manual.
FIGURE 7B
SELECTABLE SINGULATION/SLUG
1. Install an auxiliary input cable (Hytrol P/N 032.563) on any zone controller
of the conveyor. The cable attaches to the auxiliary port on the conroller (see
Figure 7A).
2. Program the zone controller to accept a slug signal. (Refer to the EZLogic®
GEN3 Component Manual for details.)
3. Connect the two wires of the Auxiliary Input Cable to any "dry contact" type
switching device, such as a toggle switch or relay.
4. With the switch contacts open, the conveyor will be in singulation mode.
When the switch is closed, the conveyor is in slug mode.
NOTE: Do not apply a voltage to these wires, or wire more than one
controller to any one contact.
• IOP Unit (Power Supply for GEN3
EZLogic®)
The model is equipped with an IOP unit (power supply). The IOP unit provides DC power for the
EZLogic® system and provides a wiring hub for advanced features (if I/O boards are present).
The IOP unit connects to the EZLogic® system by way of an IOP Tee Cable mounted in line
with the zone controller cordsets (see Figure 8B).
NOTE: See EZLogic® GEN3 Component Manual and IOP Solutions
Manual for more information.

• NBEZ Specifications

Using the specific EZLogic® controllers for NBEZ (032.5017), connect the solenoid output
cable on the EZLogic® controller to the Dual Actuator Adapter Module (Figure 8C).
The remaining legs of the tee are connected to the M8 connector from the drive module. If
you have more than two drive modules in a zone, an additional Dual Actuator Adapter Module
is required.
To connect the brake, a Braket Adapter Module is connected to the auxiliary port on the
EZLogic® controller, an extension cable is then required to connect the brake cable to the
brake via the M8 connector extended from the brake module. To connect two brakes in series
from one EZLogic® zone controller, the Dual Actuator Adapter Module will be needed to
connect the brakes. CAUTION: NO MORE THAN A COMBINATION OF FIVE
(5) TOTAL DRIVE AND BRAKE MODULES CAN BE CONNECTED TO ONE
ZONE. No additional power supply is required when using the NBEZ GEN3
controller. Power to the drive and brake modules come from the IOP. The IOP
is limited to ten 24-inch zones or eight 36-inch zones. In order to provide
I/O at the discharge of the NBEZ, an additional EZLogic zone controller is needed
with an auxiliary I/O module (032.532) and mounted to provide a zone stop or other
communication to a PLC. Figure 8E.

• NBEZA SPECIFICATIONS

The operation of the NBEZA is like the NBEZ apart from using pneumatics
for the drive and braking activities. To provide drive to the unit, connect the
solenoid output cable of the EZLogic® zone controller to the solenoid air valve
operating the zone. Connection is made by pushing the cable connector onto
the corresponding male connector of the valve until it snaps in.
The valve used when operating the drive and brake is different from the valve used
to operate the drive only. The valve on the very discharge for operating the drive and
brake is a 4-way single solenoid whereas the valve in the remaining zones is a 3-way
solenoid valve.
If there are multiple drive modules in a single zone, there is one that has a single port
air bag where subsequent modules have double port air bags to control the drive in
one zone.

• NBLR SPECIFICATIONS

The Model NBLR is equipped with fixed drive roller modules spaced every 12 inches
along one side of the conveyor to apply the driving force between the belt and tread
rollers.
