4.8.16 Relay Multiplication
This function is available from version 9.02.
With the relay multiplication table, it is possible in the MGC2 system, to assign an alarm to multiple relays.
There is a maximum of 20 entries for In-relays and Out-relays. So it is possible to expand one relay to 20 others or to
double max. 15 relays.
In the column IN, the relay assigned to an alarm in the menu SP Parameter is set.
In the column OUT, the additionally required relay is entered.
Note:
Manual intervention on IN or Out relays in the menu Relay Status or via external DI will only affect the single relay!
Symbol
Description
Default Status Function
0-30
In-Relay
0
0 = Function off
X = Relay X should be multiplied (information source)
0-30
Out-Relay
0
0 = Function off
X = Relay X should switch together with In-Relay.
Example 1:
3 relay contacts are needed with the same effect of relay 3.
(see assignment of the relays in chapter SP Parameter)
Entry: 1: IN 3
Out 7
Entry: 2: IN 3
Out 8
If relay 3 is activated via an alarm, relays 3, 7 and 8 switch at the same time.
Example 2:
2 relay contacts each are needed from 3 relays (for ex. 7, 8, 9).
Entry: 1: IN 7
Out 12 (Relay 12 switches at the same time as relay 7)
Entry: 2: IN 8
Out 13 (Relay 13 switches at the same time as relay 8)
Entry: 3: IN 9
Out 14 (Relay 14 switches at the same time as relay 9)
This means that relay 7 switches with 12; 8 with 13; 9 with 14.
The two examples can be mixed up, too.
