The Model 204 controller is designed for two channels or events, capable of handling up to four heads per channel, separately or linked. A two line multi-lingual VF display guides the operator through all programming operations in an intuitive, easy to understand format. Features common to all GMS controllers include patented automatic speed compensation for precise positioning of glue patterns, inch or metric display, batch counting, and provisions for controlling external devices such as taping heads, tipping units, air blast, and marking attachments.
