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.
