Note:
In the following examples, for ease of presentation, only one relay of FCU 8110 is
programmed. Of course 2 relays can be selected in the same way, simultaneously and
independently of each other, so that, for instance you can program the parameter "2 µ
channel ISO" for relay 1 and the parameter "flow rate" for relay 2.
FCU 8210 supplies the measuring channels : flow rate , ISO channel >4µm
(c)
, ISO
channel >6µm
(c)
and ISO channel >14µm
(c)
).
Example 1:
Switching an external unit outside a specified flow rate range (upper and
lower limit)
