1.  Starting from the standard line measuring values menue step through the main-menue 

level with the keys  

 

or

 

↑  

to

 

the main menue of the desired function (e.g. U<). 

 
2.  Branch  to the detailed-menue chain with the "ENTER" key and step up / down with the 

↓ 

and

 

↑ 

keys to the desired parameter menue. In the lower display line the setting range of the 

parameter is put in brackets, the parameter value is displayed on the right. 
 

Trip Voltage U< 

[ 23–300]  210V

 

3.  Press the 

"M/V" key

 (switches 

↓↑

  keys from 

M

enue scrolling to 

V

alue changing). 

Now there may be two situations: 
Case a) 

Lock-out Nr.xxx 

release?  yes<-

 

 no security code is selected (Code = 000):  A "release menue" (see left drawing) is displayed,  
"xxx" is a self-incremented change-access counter. Confirm the change-access release with 
the ENTER key. (If you entered this menue inadvertently you may escape from the menue 
with 

↓ 

 or

  ↑  

key). 

 

Case b)   

(If you entered this menue inadvertently you may escape from the menue with 

 or

key). 

Enter Security- 

Code.......

Enter the security code:  first the leftmost number flashes, set the correct value with the 

↓  

or

  ↑ 

keys,  press ENTER, now the mid-number flashed, proceed as just before, press 

ENTER, now the rightmost number flashes, set the correct value and terminat with ENTER. 
 
4.  Now the previous parameter menue is displayed again with flashing parameter value. This 
value may be altered with the 

↓↑ 

keys (keeping a key pressed starts an auto-increment / auto-

decrement function).  Press the ENTER key to store and activate the new setting value. The 
display returns to static. (If the changes shall be cancelled, press "M/V" key instead of ENTER 
and the previous setting value will be restored).

  There are 3 ways to continue:  
     - by the  “ENTER”  key  or  

 key to the next menue,  

     - by the 

↑ 

key to the previous menue 

     - or by the   

↓  ↑

  keys pressed simultaneously  branch to the line value menue (= “menue-reset”).

   

 

 

Assignment of output relays to individual monitoring functions and negation of output relays

 

 

Select the "Output-Relay nnn" menue in the detail-menue chain of the desired monitoring function (proceed as described 
in step 1-3 above).  The menues look like this: 
 

In the left example the monitoring function U<< is assigned to relays k1 and K4. The lower 
case character of k1 indicates, that this relay is negated. It is energized in the normal state 
and released in the tripped state.  The "--" characters mark the positions of the (not as-
signed) relays K2,K3 and K5. 

Output-Relay U<< 

 k1 -- -- K4 --

 

 

4.   After execution of step 3 the characters "k1" are flashing. With the 

↓↑ 

keys the assignment can be set or cancelled. 

(cancelled = "--"). 

 
5.  Press ENTER to save the assignment for output relay K1 and move flashing to the position of K2. Select assignment 

of K2 and press ENTER. Proceed in this way up to K5. 

 
6.  To step out of the menue press any key except the M/V key,  to restart the procedure from step 4 press the M/V key 

 

Negation of  K1 ...K5  function 

Select the menue "General Settings \ Negated Relays": 
 

 The configuration procedure is equivalent to step 4 - 6 above. An upper case character indi-

cates normal  operation, a lower case character indicates negated operation. The relay 
codes K1 -K5 are consecutively flashing and may  be toggled between upper and lower case 
character by 

↓↑ 

keys.  

Negated Relays 

= k1 K2 K3 K4 K5

 

 
 

Security Code / Change-access release

 

 
To prevent unauthorized changing of setting values via the front panel, a three-digit security code can be stored in the 
data memory. It has to be entered to get permission to alter parameter values.  
 
If the security code is 

000, 

the security sequence is

 not active 

and is replaced by a simple menue with a self-

incremented change-access counter (see step 3 above).  The value of this counter may be used as indication of any
