Relay Manager
The relay manager enables the assignment of a logical combination of functions to each relay. Each function has
been assigned a number. The numbers for these functions are entered into the configuration screen and are com-
bined to create a logical condition that energizes the assigned relay. Up to three function numbers may be com-
bined in this link. The length of the text for the logical condition must not exceed 16 characters. The control can
detect incorrect function numbers or formula constructions and will not accept these.
NOTE
The relay manager functions are listed in Appendix B: Relay Manager starting on page 149.
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 "*" has precedence over "+"
Example
of logical
conditions
and relevant
texts
Function Programmed text
Relay is enabled, if ...
... function 22 is true. 22
... function 22 is not true. - 22
... both function 2 is true and function 27 is true. 2 * 27
... function 2 is true or function 27 is true. 2 + 27
... function 3 is true or function 5 is not true or function 13 is true. 3 + -5 + 13
... function 4 or 7 or 11 is true. 4 + 7 + 11
... function 4 is not true and function 7 is not true and function 11 is not true. - 4 * -7 * -11
... function 4 and 7 and 11 are true. 4 * 7 * 11
... function 7 and 11 are true or function 4 is true. 4 + 7 * 11
... function 4 is not true or function 7 is not true or function 11 is not true. -4 + -7 + -11
NOTE
Entering an illegal logical combination will delete the equation.
Parameter 250
Assignm.relay x
3+-8+13
[x = 1 to 7]
Programming relay outputs
The relay x [x = 1 to 7] 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 underspeed" alarm is present
