Working together with DRS Technologies – Mobile Environmental Systems of Cincinnati, Ohio, ICE was selected to provide system controls programming and integration for the Common Transport Erector System (CTES) for the Lockheed Martin Missile Defense program. The CTES project was compiled of two main pieces referred to as the Common Transporter and the Common Erector. ICE was responsible for handling all controls related to the Common Erector which included an Allen-Bradley SLC 5/05 PLC, a Pro-Face GP-Pro handheld pendant controller, an AMCI Series 1500 resolver & interface module, Sauer-Danfoss proportional hydraulic valves, and various analog & discrete input signals used for tracking displacements sensors, linear transducers, and pressure transmitters.
Along with providing all of the PLC programming, HMI development, and controls integration ICE was also responsible for the panel fabrication of the electrical controls enclosure for supplying power to and interfacing all associated peripheral equipment. After shipment of the controls package we were contracted to be onsite in West Plains, Missouri where the equipment was being manufactured to support start-up. Upon arriving onsite, it was decided that we needed to incorporate a PID feedback loop into the PLC program to continuously monitor the rate of erection / de-erection, actual vs. expected positions, and hydraulic pressures due to the overall size and mass of the unit. We ended up being onsite for about seven weeks total throughout the entire project while we completed risk mitigation, functionality testing, and runoff of the equipment. Despite being a prototype, this project came together very well thanks to the extensive efforts from the staffs of DRS-MES, DRS-SSI, and ICE to ensure completion and operation of a high quality, first-class piece of equipment.
