Laser Interlock Mechanism The position of the switch (S8902) for detecting loading completion is detected by the system microprocessor, and the design prevents laser diode oscillation when the switch is not in LPS1 terminal side (when the mechanism

7、is not clamped and LPS1 signal is high level.) Thus, the interlock will no longer function if the switch is deliberately set to LPS1 terminal side. ( if LPS1 signal is low level ). In the test mode the interlock mechanism will not function. Laser diode oscillation will continue, if pin 5 of AN22022A

SERVICE PRECAUTIONS1.1 NOTES ON SOLDERING1.2 NOTES ON FLASH ROM1.3 NOTES ON PANEL CPU AND GUI CPU For environmental protection, lead-free solder is used on the printed circuit

28、 boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering. Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximatel

29、y 40 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron.Do NOT use a soldering iron

30、 whose tip temperature cannot be controlled.Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden).The following lead-free solders are available as service parts: Parts numbers of lead-free s

31、older: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.NEVER replace the FLASH ROM (IC114) on the MAIN Assy during servicing.If the FLASH ROM is assumed to be defective, replace the whole MAIN Assy.This FLASH ROM contains data that can only be written in at the factory.An IEEE 802.3-based

32、 MAC address specific to this unit has been written.After the PANEL CPU (IC8005) or GUI CPU (IC4002) is replaced, update its program.The built-in PANEL CPU and GUI CPU contains a FLASH ROM and will not operate without a program.For updating, proceed as follows: 1. Insert the USB flash memory device

33、that contains the program. 2. While holding the USB STOP key pressed, turn on the unit. Hold the USB STOP key pressed until the “Pioneer” logo disappears. 3. Updating starts.7CDJ-90056785678ABCDEF1.4 NOTES ON LINK CONNECTOR1.5 REPAIR OF THE JACB ASSYIf the LINK connector (JA1301) is replaced during

34、a repair of the MAIN Assy, detach the ID LABEL (AXW7015) from the old connector then attach it to the new connector.As an IEEE 802.3-based MAC address specific to this unit has been printed on the ID LABEL (AXW7015) be sure to attach it.ID LABELMAIN AssyWhen repairing the JACB Assy, note the followi

35、ng:On part of the initial-lot JACB Assy, the DCN1186 (470 ohms, Part description No. 471) is mounted as the resistors (R88208823, 88398844, 8855, and 8856). In such a case, mount a new DCN1186 during replacement. (See the section 10.6 JACB ASSY.)This applies only to the initial-lot products for the

36、destinations SYXJ8 and FLXJ. For products for other destinations, replace with the DCN1185 (330 ohms, Part description No. 331), as described in the circuit diagram.8CDJ-9001234ABCDEF12342.
