Relay Manager
The relay manager enables the assignment of an arbitrary combination of functions to each relay of the termi-
nals 33 to 36, 37, 38 and 47 to 48. In order to achieve this, each function of the control has its own number. A
text, which describes a logical condition that energizes the relay, must now be entered in the configuration menu
for each relay. Up to three function numbers may be combined in this link. The length of the text must not ex-
ceed 11 characters. The control can detect incorrect function numbers or formula constructions and will not ac-
cept these.
NOTE
The relay manager functions are listed in Appendix B: "Relay Manager" starting on page 158.
Permissible text/symbols for logic functions and their meaning include:
+.................... OR operator (logic function)
*.................... AND operator (logic function)
- .................... NOT operator (logic function)
1, 2, 3, .......... Function numbers
+/* ................ the following applies "*" before "+"
Function Programmed text
Relay picks up, if ...
... function 22 is applied. 22
... function 22 is not applied. - 22
... both function 2 and function 27 are applied. 2 * 27
... function 2 or function 27 is applied. 2 + 27
... not function 5 or function 3 or function 13 are applied. 3 + -5 + 13
... function 4 or 7 or 11 is applied. 4 + 7 + 11
... not function 4 and not function 7 and not function 11 are applied. - 4 * -7 * -11
... function 4 and 7 and 11 are applied. 4 * 7 * 11
... function 7 and 11 are simultaneously or function 4 is applied. 4 + 7 * 11
Example
of logical
conditions
and relevant
texts
... not function 4 or not function 7 or not function 11 are applied. -4 + -7 + -11
NOTE
Entering an illegal logical combination deletes the equation.

Assignm.relay x

[x = 1 to 4]
Programming relay outputs
The relay x [x = 1 to 4] energizes, if the logical equation is met.
Example: 3 + -8 + 13 (OR link)
3 a class F3 alarm has occurred
-8 operation mode MANUAL has not been selected
13 "Generator underfrequency" alarm is present
