The ET4 controls adhesive deposition in a wide variety of fixed speed product assembly and packaging applications. Typical applications include carton and case sealing, pallet load stabilization, cap lining and labeling. The pattern controller directs applicators to apply adhesive according to a programmed four event pattern setup. An event is an individual glue or gap occurrence in a pattern. Each glue event may be stitched, resulting in pattern versatility and adhesive savings.

The ET4 controls one or two independent valve groups. A valve group consists of up to four E100 or M100 style valves, or up to sixteen E900 style valve modules. Input signals trigger the ET4 to activate the pattern, transmitting output power to the valve groups. Two timing modes; Standard (0.001 to 999.9 milliseconds) and high resolution (0.1 to 999.9 milliseconds) allow more precise control of event duration.

Programming and adjusting pattern setups is simple with convenient toggle switches. In addition the ET-4 trigger skip function allows the timer to interrupt the deposition after a selectable number of triggers, then resume gluing at the user's preset preference.

A complete pattern control package consists of the ET4 and one or two photoeye sensors. For increased pattern accuracy, an HD1 or HD2a Head Driver should be included.
