Setting

the

LCD

Panel

ID

 

 

 

 

 

There is an EEPROM in

the inverter which stores its sup-

ported

LCD

type

ID

code.

If

you replace

a

LCD

with one of

a different

brand

or use

a new inverter,

the

ID

information

in

the

inverter

EEPROM

should

be

updated.

 

 

 

Follow the steps below to set the LCD Panel ID:

1. Boot from the Utility Program Diskette.

2. SelectLCD Panel ID

Utility

from

PC

DOS

7.0

 

 

 

 

Startup

Menu.

 

 

 

 

 

 

 

 

 

 

3. Follow the instructions on

the

screen to

read

the

current

or

to

set

a

new

LCD

Panel

ID

code.

 

Note:

When

you

set

a

new

LCD

Panel

ID

 

and the

 

new LCD is not yet enabled (to function),

 

connect an external CRT to see the program

 

execution

process.

 

 

 

 

 

 

 

Attention: Make sure the new ID code you choose

corresponds

to

the

LCD

brand

and type. If you write a

wrong

ID into

the

inverter, just

reboot

and

re-execute

the

program

and input

the

correct

ID

code.

 

4.Restart the computer — the new LCD should work normally.

Note: If

the LCD

cannot display

after

changing

the

ID

code, make

sure

you

write

the

correct

ID

code or

try

reconnecting

the

LCD FPC

cable

connectors.

 

Setting the Thermal Sensor

The system is equipped with sensors to protect against system overheating. By setting the system and processor thermal thresholds, the system can turn on the cooling Fan ASM or shut down automatically when the temperature reaches the defined threshold parameters.

System

experiencing frequent

auto

sensor

shutdown

may

need

to

reset the

thermal

sensor

threshold and

execute

the Fan ASM test to ensure

the

normal operation

of the

cooling

Fan

ASM (refer

to “Fan ASM

Checkout”

on

 

page

Follow the steps below to set the thermal threshold:

1. Boot

from the Utility

Program

Diskette.
