5 1 CAUTIONS FOR MAINTENANCE Be sure to use this manual after reading and understanding the operator s manual for the DC thoroughly. Only properly trained service technicians can repair the system. During the repair, any indications are necessary to prohibit the unauthorized persons from entering the working area and to prevent the accidents such as emitting laser to personnel. Wear protective goggles when the laser is emitted. Never look directory into the laser diode beam even if wearing goggles. Never point the probe tip or the laser aperture to personnel. Apply the lock-tight to the screws when they are loosened and tightened again. For maintenance, turn OFF the power and disconnect the socket from the wall-outlet unless this manual specifies Turn ON the power. In case that the abnormal smell and/or noise is produced from DC-3300, turn the key switch to the OFF position immediately or press the EMERGENCY OFF button. When performing a maintenance with the covers (upper, lower or front cover) removed, take the following measures in order to protect the laser diodes from static electricity. Spread a conductive mat on the workbench, then connect the earth wire from the mat to a ground. Field service representative should put a wrist strap on his/her wrist, and connect the earth wire from it. Earth the measuring instruments such as oscilloscope and laser power meter as well. Use a soldering iron provided with an earth wire. Before using a tool, always touch the metal part to the conductive mat. Connect an earth wire to the terminal on the rear panel as well. Specifications and design are subject to change without notice for improvement. Since the Technical Bulletin will be released every time significant changes are made to the system, refer to the Technical Bulletin together with this manual.

44 DIP SW function list A DIP SW (SW1) list and its operation are shown below. DIP SW is usually set to the ON position. When it is set to the OFF position, the following operation will be performed. DIP SW is on the display board. Note: Set all switches back to the ON position after the operation is finished. Even if one switch is set to the OFF position, D.P. (Decimal Point) is displayed on COUNTER. ON = OFF = DIP SW Operation/ Function Content #1 Cancel Interlock Cancel the detection of Interlock. However, laser irradiation is stopped by the hardware at the time of interlock. #2 Cancel Error #3 Not in use #4 Current/Light Mode switching #5 Continuous irradiation mode #6 Parameter setting mode #7 Not in use #8 Service mode Cancel the detection of Error. "ON" : Light control mode "OFF" : Current control mode Continuous irradiation setting is available. Parameter setting is available. Laser output, and display of current, etc. 6.6 System parameter Change/Setting method of value of parameter 1. Set No. 6 of the DIP switch (SW1) on the display board to the OFF position. When it is set to the OFF position, data will be displayed on the following indications. Address: TIME indication of the display panel Display character: COUNTER indication and S.SIZE indication on the display panel Initial value or value of parameter: POWER indication on the display panel 2. Press the switch or of TIME on the display panel to display the address to be changed. 3. Change the parameter value by turning the POWER knob. 4. Check the beeps by pressing the RESET switch (Completion of change and setting). 5. Set No. 6 of the DIP switch (SW1) of the display board back to the ON position. Note1) Except correction of laser output and change of the opening-and-closing timing of each shutter, the reclosing of KEY SW is required. Note2) If the power is turned off with the DIP switch (SW1) No.6 set to the OFF position (with the parameter display after parameter change), Err91 (data failure of EEPROM) is displayed at the time of next power-on. Be sure to turn off the power after setting No.6 to the ON position. If Err91 is displayed, set No.2 of the DIP switch (SW1) to the OFF position. After restarting the system, reset the parameter with the procedure of 1 to 5.
