The document summarizes various control system and electrical contracting projects undertaken, including: simple pump control systems, autoclave control, heated press control, designing and building viscometer systems to measure viscosity, building viscosity control systems, automating a filling production line, building dispensing and mixing control systems, undertaking modifications and repairs in various industrial environments, building electronic motor control boards, and various motion control systems using PLCs. It also lists electrical contracting work such as inspection and testing, lighting installations and repairs, new power installations, replacement of distribution boards, fault finding, machine moving, dado trunking installations, hotel rewiring, power surveying, and emergency lighting testing.

1. Type of work undertaken
Control Systems
• Simple start stop pump control utilising floats for sewerage tank systems.
• Autoclave control using Siemens S7-200
• Heated press controlling temperature and pneumatics using Siemens LOGO.
• Designed a viscometer using the traditional weight falling through fluid method. I have built two
types of these using the Siemens S7- 200 series and a later model with the S7-1200. The system
used a combination of pneumatics and sensors to calculate viscosity.
• Built a viscosity control system using the above viscometer to maintain a constant viscosity of a
tank of conformal coating fluid.
• Automated an aerosol can filling production line. The pneumatic control was upgraded to PLC
control using an S7-1200. The speed and reliably was phenomenal, the client broke all
production records and the cost was recovered within months.
• Built dispensing and mixing control systems to control the filling of a vessel with two parts. The
volume of material is weighed so the correct amount can be added to the mix. Once the correct
materials are in the vessel then the mixing process begins.
• Undertaken modifications, fault finding and repairs to existing systems working in
Pharmaceutical environments, food production and engineering works.
• Built electronic motor control boards to operate linear actuators to move doors and wood
panels in an office environment.
• Motion control system using Siemens S7-1200 and stepper drivers to precisely control the
movements of a hidden camera in an office environment.
• Motion control system using Mitsubishi Q system on a sealing machine.
• Radio transmitter installed in a forklift truck that activates warning beacons in a warehouse once
the forklift is active.
• Variable speed drives for controlling speeds of extraction fans and mixers.
• Built guitar valve amplifiers and carry out repairs and re-valving.
Electrical Contracting
• Inspection, Testing and Certification.
• Lighting repairs either re-lamping or replacements
• New installations of power and lighting
• Replacement distribution boards and consumer units
• Fault finding and repairs
• Machine moving (Electrical)
• Dado trunking installations for I.T. classrooms in schools or offices
• Rewired a wing of a recent hotel refurbishment.
• Power surveying and reporting
• Emergency lighting testing and repairs
