Integration of the filter in the
building control systems
The filter can be integrated in a building
control system (e.g. EIB, LCN or LON) via
the potential-free signalling relay and the
external input of the filter control ("pot.-free"
version only).
The potential-free signalling relays are
connected, for example, to a binary bus
coupling unit.
Thus fault messages or the filter flushing
signal can be forwarded to the building
control system.
In addition, the external input of the filter
control can be used concerning the remote
control (flush start-up, flush-blocking).
Operation
Specification
Starting of the flushing operation: By closing a switch
contact (brown and red core) connected to the potential-free
input.
If the switch contact at the potential-free input (brown and
red core) is closed the filter cannot effect a flushing.
If the backwashing interval time has expired the flushing is
carried out as soon as the switch contact of the potential-
free input is opened.
Relay 2 closes after the backwashing interval having
expired or after pressure exceed occurring at the differential
pressure sensor and thus displays the call to backwash.
Simultaneously the yellow LED blinks: "Flushing".
The flushing can only be started by means of the manual
button or a switch contact connected to the potential-free
input.
Not allowed. Continuous sound signal till the switch is
adjusted.
5.10 Modifications / changes /
(see
dangers due to non-compliance")
Arbitrary modifications and changes are
prohibited for safety reasons! They can
impair the function of the filter, lead to leaks
and as an extreme incident they can lead to
the bursting of the filter.
The imprinted test marks are only valid if
original spare parts are used.
