3.3.5. Connecting Q-network Modules and load sharer
3.3.5.1. Flow Control
Q-Network Modules and Load Sharer may only be installed by authorised EC POWER specialists. Q-Network Module Cables
must not be shortened, extended or cut off.
Q-Network Modules are networked with other Q-Network Modules and the Load Sharer with other Load Sharers via a Q-
Network Cable (SFTP (CAT 6) network cable). Unused RJ45 plugs must be covered with RJ45 (8x8) ISDN network terminators.
Sensors must be positioned as shown in Fig. 3.14. Other positions will cause operation errors!
Fit the flow temperature sensor downstream of the XRGI flow connection (T-f).
Fit the return temperature sensor upstream of the return connection (T-r).
The sensors must be attached to the pipe using the clamps supplied and then be insulated.
If the pipes run horizontally the Flow Control sensors must be fitted on top of the pipe. It is best to use baffle plates to induce
mixing.
The Flow Control is networked with other Q-network Modules via a network cable (SFTP (CAT 6) network cable).
