After completing the change, one can transfer
- to the next menu using the "ENTER" or "DOWN" button,
- to the previous menu using the "UP" button,
- back to the line value display menu (= "Menu reset") pressing "UP" + "DOWN" simultaneously.
Assignment of output relays to individual monitoring functions and negation of output relays
Select the menu "Output-Relay nnn" of the respective switching stage (in accordance with step 1 to step 3 as above).

4. After execution of step 3, the characters "k1" are flashing. The allocation of the U<< triggering with k1 can be deleted
or deactivated using the "UP/DOWN" buttons (in this case, the placeholder "--" is placed instead of "k1").
5. The settings for k1 will be accepted by pressing the "ENTER" button and the change mode will be switched forward to
K2, the placeholder for K2 flashes. Using this method, the positions for all 5 relays will be passed through.
6. After the completion for K5 (using the "ENTER" button), the "M/V" button can be used to start the change mode again
at k1, or a different button can be used to vacate the menu.
Negation of K1 ...K5 function
Select the menue "General Settings \ Negated Relays":

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
access to the change mode. The security code can be modified in the menue "General Settings \ Security code". Subse-
quent changing of the code is possible, but also in this case the active code has to be entered to get the permission for
changing.

3. Press the "M/V" button Switches the function of the arrow keys from "Menu scrolling " to
"Value changing"). Now there may be two situations:
Case a): 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 re-
lease with the ENTER key. (If you entered this menue inadvertently you may escape from the
menue with "UP/DOWN"
Case b): Change release for an activated combination lock, the first digit flashes.
(If you got to this menu by accident, then please leave it by using the "M/V" button.)
Otherwise, using the "UP/DOWN" button, set the first digit correctly and press ENTER.
The second digit flashes now, adjust it, press ENTER and set the third digit. Complete with
"Enter".
4. Afterwards, the parameter menu will be displayed again and the first digit of the setup value
flashes. The decimal place can now be changed using the "UP/DOWN" arrow keys. (Automat-
ic increment or decrement if button is pressed). The next decimal place flashes after pressing
the ENTER button. After the last decimal place, the new value will be transferred into the
memory by pressing "ENTER" and the value will again be displayed static. (If the change must
be reversed, then the earlier value can be reestablished by pressing the "M/V" button instead
of ENTER).
The switching stage U<< in the left example acts on the relays k1 and K4. The lowercase
letter for k1 shows 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 assigned) 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 charac-
ter by "UP/DOWN" arrow
