Our controller had a nasty accident. The display backlight supply touched chassis and burned out a 74hct245 data buffer then sent high voltage down the ribbon cable to the controller board and burned out seval chips. I can replace all the chips but the eprom with the software is toast. If anyone could make an image it could really save my bacon. I used a very simple arduino project to read it. Three data lines stuck.

Hi Marc. You might be able to help me, I have a Sumitomo-Yale 41-FBPVIII Forklift which has a Nichiyu PB83-90 controller. It was not responding and I found the backup battery was dead. I replaced it but now the display is throwing messages in Japanese. Is there a way to reset this board to factory settings ?

Hey Minh, the voltage on the back-up battery must be around 3,6 Volt. Just put the contact ON for a few seconds and put OFF again. If it works the machine is in it's factory settings.

Hey Minh, You can try to do a reset of the display board. Connect the first and last pin of the 8 pins PC connector switch ON the contact switch and switch it back OFF, disconnect the first and last connection you've made and try again by switching the contact switch (don't do this with the other cards!!!). Have you bought an original back up batterry of Nichiyu?

hey Alexandr, your right. It's just for changing the software on the display board and MPU-Board. If you have the software and you can connect it with your computer you have to learn Japanese. I have seen it used by a Japanese Technical person a few times, he could change the download speed of a forklift with fingertip control. He told me then that it could'n be used for testing any functions.

ok thanks,
but even so, if there are connectors on the display module and the MPU module that means something must have?
