DynaGen ES52 Engine Controllers Keep Terex Light Towers Moving Throughout the Night

Application Note



Terex is a global manufacturer of lifting and material handling equipment for a wide range of commercial applications. They offer safe, heavy-duty, easy-to-use models of trailer-mounted light towers with a variety of features and options to maximize the productivity of each unit for jobsite needs.


Whether at a construction site, a mining operation or some other outdoor location, light towers are ever-present for projects requiring work to proceed day and night. Keeping those light towers operational through the night is imperative for providing safe working conditions and ensuring productivity is maintained. They required an engine control module with an automated start/stop feature to manage their Terex AL4000, AL5000 and AL8000HT light towers.


DynaGen's ES52 autostart engine controller is designed for harsh environmental conditions delivering resistance to shock, temperature extremes, moisture and electrical interference; the types of conditions into which these light towers are often placed. Providing light towers with an automatic lighting management system, which provides automatic on/off light control by photocell, timer or both, is a cost-effective way to increase productivity. Allowing the light towers to be shut down automatically results in fewer personnel hours spent manually controlling the units. In addition, fuel costs can potentially be reduced by not running the lights during daylight hours. The ES52 control unit offers several features that are engineered to allow for easy installation and easy service. Its production-line friendly design includes plug-in terminals, high capacity removable relays, built-in kickback diodes, a pre-installed and removable fuse and the capacity for direct generator connection. It also offers full field adjustable settings. Another useful feature of the light management system is the ability to preset a light tower's start up or shut down with a programmable timer. The tower might start up automatically with diminishing ambient light, but an operator may wish for the lights to shut down before daybreak. DynaGen also supplies the timer to Terex.
