Safety Precautions Before performing either replacement procedure, remove all power from the system and lock out external power to the electrical cabinet. ; WARNING: Failure to lock out external power to the electrical cabinet may present a serious shock hazard. The input terminal block remains energized with the power OFF. CAUTION: Static electricity can damage EPROMs and boards. Before handling or transporting any board or EPROM, put on the grounded electrostatic discharge (ESD) wrist strap supplied with this kit. For maximum protection, work on a grounded ESD surface. 3. Recording Your Controller User Settings If when you replace the existing controller or option board EPROMs, the user settings will be lost ancl reset to the Nordson defaults. Therefore, after replacing either the controller or the EPROMs, you will need to have available the Table 4.1 Default Settings for OmniScan Control System from section 4 of your applicator system manual so that you can re-enter this data. These are the pages where you entered data on your initial setup. Note: If you did not previously record your user settings, you must go through the menus to get this information. This time make sure that you record these settings for future use. Refer to the part of these instructions that apply to your kit. 4. Replacing the Controller Assembly The following two procedures describe how to remove the existing controller assembly and install a new controller assembly. If you are just replacing EPROMs in an existing controller, go to the EPROM Replacement procedure described later in this document. Once the new assembly is installed, you are then referred to a procedure describing how to check installation and configure software. Removing the Old Con troller Assembly 1. Move the melter circuit breaker to the OFF position. 2. Disconnect and lock out the input power to the melter main circuit breaker. Refer to Figure 1. Figure 1.
