Chapter 13: Replacement of the JW-21MN

When you want to change the JW-21MN due to an operation fault (lighting UNT.E lamp) etc., follow the procedures below.

Make sure to store the set parameters onto a floppy diskette using a support tools. (See the next page)

Operation procedure

Start

Turn "OFF" the JW20/JW20H/JW30H's power

Remove the cables from the JW-21MN

Remove the JW-21MN from the rack panel

Loosen one retention screw and take out from the rack panel.

Set the switches of the new JW-21MN

(See chapter 11)

Install the new JW-21MN

Connect the cables to the new JW-21MN

Turn "ON" the JW20/JW20H/JW30HÕs power

Load the parameters.

End

(See page 5-1)

Load the parameters stored in the floppy diskette into the new JW-21MN and write in the EEPROM, then start operation. For details, see chapter 14.
