The TDS Controller with limiting function, FARB2, is used for monitoring the TDS 
as stated in EN 12953-6. The TDS of the boiler water has to be monitored 
continuously to ensure that the TDS stays within the given limits. 

The relevant standard for safety accessories, EN 12953-9, does not give specific 
requirements for TDS limiters. Thus a type approval is not feasible. 

It goes without saying that the general requirements for safety accessories set 
out in EN 12953-9 were met during the development of the FARB2. 

 

5.  Design and installation FARB2 

The  device  is  supplied  in  a  plastic  plug-in  housing  for  fitting  into  switch  cabinets.  The  housing  is 
designed for quick fitting with a spring catch for the DIN EN 50022 standard 35 mm carrier rail and 
for screw fixing on a mounting plate. 
 

If the device is used in environments with increased exposure to vibration (e.g. 
marine), the fixed installation on the mounting plate must be used.
