Cause
Cause
Cause
Connection via an intra-company LAN may slow the Web screen display due
to a busy network. Use the system during off-peak hours of network use, or
use a dedicated network to connect a PC with the controller.
If a 10 BASE switching HUB is used, replace it with a 100 BASE switching
HUB.
If some application programs are operating other than the browser, the PC
performance may degrade. Close the operating applications other than the
browser, and check if the PC performance improves.
The supported browsers are Internet Explorer 6.0, 7.0 and 8.0 and Firefox
2.0, 3.0, 3.5 and 3.6. If a browser other than these browsers is used, the
contents may not be displayed properly. Use one of the supported browsers
to see the contents.
If other users are performing schedule setting or other operation, the display
switching may slow down. Wait for a while, and access to the controller again.
The controller regularly writes a file for electricity distribution. The display
may slow down during the writing process.
If the controller is accessed from a browser while the controller internal
processing is in progress, the controller performance degrades. To prioritize
controller internal processing (writing a file or giving instruction to an air
conditioner), the system once stops the access from the browser. Log on
again.
Turn on the controller. Wait for 5 minutes and logon again.
Turn on the HUB and log on again.
Check that the LAN cable is inserted into the controller and PC and connect
them.
After that, Log on again.
Turn off the controller and wait about 30 seconds. Turn it on again, then
access from the browser software after 5 minutes.
Check that the controller and HUB are turned on.
Check that the LAN cable is connected.
Check that the LED of the controller LAN connector is lit.
* If the LED of the LAN connector does not illuminate, the controller is
defective. It needs to be repaired.
Restart the PC and check again if it works.
Replace the PC and check again if it works.
Replace the LAN cable and check again if it works.
