UDP command:

"TCH-OK :done" 

 

 

Description: 
 

 

[Timeout] 

10...600 = Within this time, a command "ena" or "curr" must be 

 

 

received, in order not to activate the failsafe mode. 

 

 

0 = Disables the failsafe mode. 

 

[curr] 

 

0 = Disables the charging process when triggering the failsafe 

 

 

function, similar to command "ena 0". 

 

 

 

6000...63000 = Reduces the maximum allowed charging current 

 

 

to this value (in milliampere), when triggering the failsafe function. 

 

[save]    

0 = Activates the failsafe function only temporary until the next 

 

 

startup of the device. 

 

 

 

1 = Saves the settings into the EEPROM in order to activate the 

 

 

failsafe function automatically, after restarting the device. 

 
By default, this feature is disabled and must be enabled once or after each restart. 
This function is used to limit a network charging station with a lost communication 
(network error, server failure, ...) to a defined state. This can be necessary in con-
junction with a peak load limitation, in order not to overload the main fuses. 
An activated failsafe function is indicated by the charging station. In this case the 
LED segments do not longer illuminate the full width, but only indicates the current 
state with the middle two LED segments. 
A triggered failsafe function can be also recognized over UDP: in the report 2 the 
"

Enable sys

" value goes to 0, and the charge current setting "

Max curr

" goes to 

the default value of "

Curr FS

". 

After the failsafe function has been activated due to a timeout, you must set the val-
ues of current and the load enable again using the associated commands "curr" and 
"ena".
