Configuration via web browser 

The configuration routine is accessed to via the browser by means of the IP address specified under 
Chapter 5.3.2 Operating display / network for browser accessing (Figure 17 – Network information). 
 
The LS 804 load switch has been operably tested under the following browsers/operating systems: 
- WindowsXP     

 Web-Browser Chrome, Firefox, Opera, Internet-Explorer 

- Windows7/8/10 

 Web-Browser Chrome, Firefox, Opera

Status (information) 

After the configuration routine has been accessed to via the browser, the following image will appear: 
 

 

Figure 26 – Status information (LS804.01) 

 

The "

Channel information

" section contains the display for sensors a to d as well as the cumulative loads 

a/b, c/d and a-d along with additional system information. 
  
In the event of an error occurring, the causes of failure can be determined by actuating the “

Error Status

” 

link (also refer to Chapter 7.2 Status of relays Error1 and Error2). 
 
Actuating the "

Relay status

" link will display the status of the contacts K1 to K6 (also refer to Chapter 7.1 

Status of relays K1 to K6).
