4.5 Conveyor Speed
The conveyor is driven by a 1/8 hp DC motor controller. While the motor itself is part of
the conveyor, the speed control board is located in the base. The conveyor is turned on or
off by a Run relay (similar to the transport, energized by the Base Control Board). This
will also depend on the setting of the conveyor mode switch (front panel):
ON
means that the conveyor will always run as long as the base is powered, regardless if
it is running or not.
OFF
means that the conveyor is off, regardless of the status of the base.
AUTOmatic
means that the conveyor will run as long as the base is running and stop
when the base is stopped. The conveyor speed is controlled by 2 front panel
potentiometers: “Conveyor Speed” and “Stack”. The selection is done by the Stack Relay
(front compartment), which is activated by the Base Control Board at the request from the
control computer.
4.6 “Universal Speed Control” (Optional)
The “Universal Speed Control” is a concept, which permits the control of the transport
speed of all machines in a system with a single “Master Controller” (plugged into a
dedicated socket on the front panel of any machine in the system).
The capability of implementing this system is built into all newer model Buskro machines,
including the BK7IB-2. The system requires that all machines in a system are equipped
with a special control board. The machines can either be ordered with the boards already
installed, or they can be retrofitted in the field. If a machine is not already equipped with
the board, a retrofit consists of simply replacing the current “dummy” board with the
proper one and calibrating the unit. All wiring is already done and all interconnections
required are already wired and connected in the machines and the interconnect cables.
The “Master Controller” may be plugged into any machine in the system, since its signals
are carried on a special bus. Once the speed is set, the controller may be removed and the
