| Customer Requirements: |
| Design, supply and commission the PLC-based control
systems to control a Limestone Block Manufacturing Machine.
This machine has been designed and built by Dynamech Equipment.

| Solution: |
The control solution for this project comprises
of 1 x Koyo DL06 PLC which interfaces to a series of hydraulic
drives via solenoid valves. The system is capable of operating
in Manual and Automatic modes. In the Manual Mode, the operator
controls the sequencing of the machine by activating a series
of control switches. A UniOp text display panel is included
to display operator messages, including the current operation
being performed by the system (so that the operator never “forgets”
which stage he is up to). The PLC provides interlocks to prevent
the operator from performing the operations out of sequence,
with an additional override function to allow the operator to
perform out-of-sequence operations if required.
In Automatic Mode, the operator needs only to press the Start
pushbutton for the system to operate in a continuous cycle.
The operating sequence is controlled by a set of limit switches
which indicate the current status/position of the machine’s
hydraulic drives. In this mode, the machine operates at the
maximum possible speed to optimise production.
Safety alarms and interlocks were added to ensure that the system
is stopped in the case of limit switch failure or emergency
stop. |
