Quick Check of Module Operation Proper module operation is quickly checked by placing a pin into the top of the module (Figure 17), then manually operating the applicator solenoid. During proper module operation, the pin should move up and down, and adhesive should flow from the module. If no adhesive flows, refer to Table 3, in this section Figure 17 Manual Check of Module Operation The Troubleshooting Guide, Table 3, lists typical applicator faults, their probable causes and appropriate corrective action. NOTE: The Nordson Hose/Applicator Diagnostic Device enables precise and complete heater and RTD troubleshooting for RTD controlled H200 applicators. The device can quickly troubleshoot applicator RTDs and heaters without removing the applicators from the hoses. Contact a Nordson representative for further information Nordson Corporation
