Table 2 provides an illustration of the hazard identification symbols that appear on each safety label and tag, the meaning of the symbol, or the exact wording of any safety message Figure 1 Safety labels and tags Table 2 Safety Labels and Tags Item Part Description [Hot surface] 2005 Nordson Corporation

16 12 E400 Electric Applicator Description The E400 electric applicator applies hot melt adhesive to a product. The applicator is equipped with platinum resistance temperature detectors (RTDs). Four cordsets separate the temperature sensors (RTDs) and heaters for both the heated adhesive and air manifolds. Figure 2 shows the key parts of a typical E400 applicator. Driven by an electric applicator driver (usually an E400 driver), the E400 applicator provides all-electric actuation, eliminating the need for compressed air (except in spray applications). Adhesive enters the inlet port of the applicator and is directed through the manifold into the module seat, which is sealed by the end of the armature. When the applicator coil is energized by the driver, the armature lifts off of the seat, allowing the adhesive to flow from the applicator. The armature is held off the seat by the magnetic attraction of the coil. When the driver de-energizes the coil, the coil loses its magnetic attraction and the armature is forced back into the seat by a return spring, stopping the adhesive flow. Because the E400 applicator uses a Universal module, it can be configured with an appropriate nozzle for the types of spray applications described in Table 3. An adapter is required for the Controlled Fiberization (CF) application.
