C2i (Control Instruments, Inc.) Services

Control Instruments, Inc. takes pride in its efforts to ensure the quality of the products we use and the systems we supply. Equipment is selected on the basis of its suitability to the application, taking into account the environment, severity of duty, and requirements for interfacing with other equipment. Ease of maintenance, availability of parts and service, and past experience with the types of equipment involved are major considerations.

All equipment is inspected on receipt. Whenever possible, systems are tested as a whole in our shop under conditions simulated to those encountered in the field. Any problems with the equipment or the system are corrected in the shop before shipment.

C2i provides complete testing for each of its systems prior to shipment whether specified or not. C2i is a certified and regularly inspected UL 508 and UL 698 panel shop. Though special equipment is engineered into systems which must bear the UL 508 or UL 698 label, each panel delivered by C2i is built to UL 508 and NEMA standards whether specified by the consultant or not. The UL 698 is an intrinsically safe panel rating which UL has qualified C2i to manufacture.

C2i maintains an ongoing and constantly improving quality control regimen. Design and programming engineers are required to be present for all testing and quality control procedures. No equipment is shipped until it is fully tested and signed off for by the project engineer and the project coordinator.

C2i routinely conducts witnessed factory tests in its large manufacturing facility. Factory tests range from small analog systems to complex SCADA systems with multiple workstations and dozens of radio based remote terminal units.

To assist in testing C2i utilizes a mobile simulator that can output and accept multiple discrete and analog signals.







C2i operates six separate service locations to provide the best support possible. Each service facility coordinates through the Atlanta-based project coordinator to maintain an accurate schedule and to streamline the dispatch of service personnel. Each service center is provided with a company truck stocked with equipment.

C2i field engineers are equipped with the latest test equipment to aid in the calibration and service of equipment on project sites. C2i also maintains a stock of the most commonly used components to ensure prompt service.

Maintenance and service on field components usually is re-calibration. Maintenance and Service requirements for solid state computer systems are minimal at worst. C2i, headquartered in Atlanta, Georgia, is staffed with qualified personnel who can troubleshoot and correct common hardware problems associated with desktop computer platforms over the phone. Programming engineers are available to assist operators with software problems. C2i provides a modem and a "Reachout" type software package with the computers supplied on a system. This feature allows C2i engineers to troubleshoot computer problems from their desks in Atlanta--a value added service that is incorporated into every system we supply.

On-Site training begins during start-up. A Control Instruments field service technician will demonstrate programming and calibration procedures on each instrument as it is commissioned. After classroom training, additional hands-on instruction will be provided to help clarify operations and maintenance procedures.

Detailed classroom training will be provided in the following areas:

  • Overall system design and theory of operation.
  • Detailed operating procedures, covering both normal and alarm conditions.
  • Maintenance procedures, including suggested practices and intervals, as well as detecting potential problems.
  • Troubleshooting at both the system and device levels. Discussion of the potential causes of failure, troubleshooting methodology, and proper use of tools and test equipment.

Operations and maintenance manuals are supplied for the training sessions. They are typically divided into sections detailing field equipment, panel devices, software and program information, and system and panel drawings. A detailed system operation description is also included.

Supplementary training is available to reinforce initial training or to provide more detailed instruction in specific areas.
