1 EPROM Replacement 1 EPROM Replacement for OmniScan@ Contrbl Systems Important 0 Before starting, read all instruction sheets that have been provided with your service kit It is recommended that you use an anti-static wrist strap (P/N ) when handling PC boards or EPROMs Exercise care when handling EPROMs to avoid damaging them The EPROMs can be damaged by electrostatic discharge (static electricity) General guidelines for handling static-sensitive EPROMs are as follows: Leave the EPROM in the plastic static protection wrapper until just before it is needed Dissipate any accumulated static charge by touching grounded metal before touching or handling an EPROM Handle the EPROM by the edges Avoid touching component pins e EPROMs can also suffer mechanical damage through rough handling Use care when laying an EPROM down Do not place other objects on top of an EPROM NOTE: The main control board contains three EPROMs Option boards, if installed, also contain EPROMs The software version number of EPROMs on option boards must match the version number of EPROMs on the main control board in order to function properly Determine the Software Version 1 Turn the applicator ON 2 Press PROGRAM - t (UP ARROW) + INFO - VERSION This will provide the software version currently in your unit 3 Inspect the labels on the EPROMs included with your sewice kit The label format is SW# xyyy/n 4 If the software versions (xyyy) are the same, proceed with step 3 of Replacing the EPROMs 5 If the software version on the replacement EPROMs is newer, you must replace the EPROMs on all boards in order for your system to function properly Proceed with step 1 of Replacing the EPROMs Q Nor&on Corporatm 1992 All Rights Reserved issued 6B2 PrnloastSA lnrtructbnr48-198

2 2 EPROM Replacement Replacing the EPROMs 1 When you replace the EPROMs, the user settings will be lost and reset to the Nordson defaults Access the PROGRAM mode and go through all the menus Write down the value of all settings You may find the yellow pages at the end of Section 4 of the Operator s Manual convenient for this task 2 Access the PROGRAM - SETUP + CONFIGR menu and record the present conifiguration code If the unit is not operational, obtain the configuration code from the hose-end panel of your unit 3 Follow the instructions on Removing the Option Board for removal of the board(s) Figure 1 Release EPROM 4 Locate the EPROMs on any option boards which may be installed Push down on the slide latch on top of the socket (in the direction marked OPEN ) to release the grip of the socket Remove the EPROMs See Figure 1 5 The new EPROMs for option boards are identified on the label as follows: SW# xyyy/n where n is the chip number h Chi # U# Location 5 I/O Contact Option 10 RS-232 Option 3 Motor Control Board 3 Analog Input Option 6 Note the orientation and order of the EPROMs and carefully insert them in the sockets Figure 2 Secure EPROM 7 Push the slide latch on the bottom of the socket up (in the direction marked YACT ) to secure the EPROMs in place The slide (marked OPEN) will reappear See Figure 2 8 Locate and remove the three EPROMs on the top left corner of the main control board 9 The new EPROMs for the main control board are identified on the label as follows: SW# xyyy/n where n is the chip number 0-O X cl Figure 3 Main Board EPROM Locations Chip # I U# I Location 38 Main control board 39 Main control board 40 Main control board 10: Note the orientation and order of the EPROMs and carefully insert them in the sockets See Figure 3 Pm A lnstructms lasued No&on Coqxxabon 1992 Al Fllghb Resserwd

4 4 EPROM Replacement Removing the Option Board 1 Disconnect and lock out input power to the applicator WARNING: A 4 Failure to disconnect external power to the applicator presents a serious shock hazard The power line input terminal block and input terminals on the circuit breaker are still electrically energized if external power to the applicator is not disconnected, even though the circuit breaker is off 2 Remove the electrical cabinet cover by unscrewing the captive screws on top of the cabinet and disconnect the ground wire 3 Loosen the captive screws on the front and rear covers that attach the covers to the control frame and the center frame 4 Loosen the two nuts located under the control frame Carefully pull the control frame iassembly out until it comes to a stop 5 Disconnect all wiring harnesses and ribbon cables from the main control board and any attached option boards Record or tag which cables go toi which connectors to assist with the re-assembly 6 Disconnect the ground wire from the quick connect at the bottom of the display panel 7 Remove the screws from the front of the display panel Note that the door latch bracket will also come loose Set the bracket and screws aside 8 Remove the display panel and main control board assembly from the control frame and lay the panel face down on a clean, flat, soft surface This will help avoid scratching the display panel in the steps that follow VIE I/O Contact Option Motor Control Option / \ SW1 TOP VIEW on ON OFF on Pos1 Poti 1 1 2,W SIDE VIEW 1 On On 2 2 1,394 2 On Off 3 3 x2,4 3 Off On 4 4 x2,3 4 off off Figure 4 Option Board EPROM Positions PIN A lnshuctms 46-l 96
