Below is a small sample of some past projects RSTech has provided to it's customers and end users.  RSTech has worked on hundreds of projects over the past several years from all types of industries.  The projects vary from complete control systems to programming only, drawings only, and panel build only.  RSTech can provide any or all portions of your next control system.  We are very flexible and offer ideal solutions for machine builder (OEMs) and end-users.

	Shot Blast Machine This was a turn-key electrical project where RSTech provided design, drawings, panel build, programming, installation (field wiring) and on-site start-up.  The system utilizes an Allen-Bradley CompactLogix PLC and PanelViewPlus1000 (10") HMI terminal. Installation involved providing the main power drop from the customer's bus duct and wiring all sensors, motors, etc. on the machine back to the main control panel.
	Two Burner Gas Furnace RSTech provided design, drawings, programming, and on-site start-up at the end user's facility.  RSTech was hired by the machine builder (OEM) for the electrical engineering portion of the project while the OEM provided all the material and panel build activities. The system uses an Allen-Bradley ControlLogix PLC and PanelViewPlus1000 (10") HMI terminal.  Temperature is controlled by the PLC using PID functions.  The system features recipe management for storage of the various temperatures for 100 different production parts. Animated objects on the PanelView clearly show blower motors turning and burner flame status.  Trends allow the Operator to look at the temperature and set point and how they respond over time.
	Two Hoist System A machine builder (OEM) hired RSTech for design, drawings, programming, supervision of the panel build, and on-site start-up at the end user's facility.  The system uses an Allen-Bradley ControlLogix PLC, PanelViewPlus1500 touch screen HMI terminal, ArmorBlock remote I/O modules, Flex I/O, and DeviceNet communications. The hoists utilize an absolute encoder for precise positioning that never requires homing.  Recipe management allows the end-user to customize the hoist steps and duration of product in the various tanks.  Automated level and temperature control of the tanks was also integrated into this system.
	Automated Rectifiers for Plating RSTech provided design, drawings, panel build, programming, and on-site start-up at the end user's facility.  The system uses an Allen-Bradley ControlLogix PLC and PanelViewPlus1000 (10") HMI terminal.  The initial project was four new rectifiers however an additional six retrofits were added to the automated system at a later date. The project continued to grow with another six new rectifiers and six more retrofits added.  The additions used Point I/O on Ethernet/IP and a remote ControlLogix chassis on ControlNet.  The system uses recipe management to handle up to seven customizable steps for 1000 different recipes (production parts).  A remote access dial-in modem/switch is used for remote trouble shooting and program changes. The PanelView display current and voltage from the rectifiers and allows the end-user to run based on time or Amp-Hours.  Although not required in this type of system, the end-user requested the system have redundant manual controls utilizing knobs and meters to allow them to bypass the automated system.
	Hoist System Control Panel RSTech was hired for electrical drawings and control panel build.  An out-of-country OEM required the expertise of a local company to provide a control system that conforms to local electrical safety code and accepted local industry standards.  RSTech's past experience and recognition as an Authorized Electrical Contractor provided the OEM with an ideal business partner for this project.  The system uses an Allen-Bradley CompactLogix PLC and ABB Variable Frequency Drives (VFDs). The customer provided their own programming and installation.
	Water Quench System Upgrade The customer was having on-going problems with their existing water quench system where tank levels and temperatures were not properly maintained.  The tank was often overflowing and the temperature too hot.  RSTech upgraded to a larger PanelView with more animated and dynamic graphics and completely reprogrammed both the PLC and PanelView programs.  While on the project RSTech also upgraded the level sensor to an ultrasonic, non-contact sensor with analog feedback.  RSTech also removed old equipment from the panel and performed drawing updates and a panel clean-up to ease trouble shooting for the plant's maintenance staff.
	Food Processing Equipment Drawings RSTech was contracted by a food processing facility to produce electrical drawings for various equipment to pass electrical inspection.  The customer purchased previously-used equipment that did not have electrical approval or electrical drawings.  RSTech traced every wire in the system to create an accurate and up-to-date set of electrical drawings.  These drawings along with equipment labeling allowed the equipment to pass inspection.
