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:
Output-Relay U<<
k1 -- -- K4 --
4. After execution of step 3 the characters "k1" are flashing. With the

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

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

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.
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
