5.4 Functioning
5.4.1 Standard operation
The Megacontrol is an intelligent control unit for
different components of pressurization systems
consisting out of a maximum of 6 pumps. The
required system pressure is sensed by a pressure
sensor on the outlet side of the installation.
When as a result of a decreasing water volume the
pressure drops below the pressure set point, a pump
will be switched on.
When the required system pressure has been
reached, the pumps are switched off one at a time.
The minimum run time is optimized constantly, which
results in a considerable energy saving.
5.4.2 Custom made settings
The Megacontrol can be programmed through the
human machine interface (HMI) operating panel and
has been protected against unauthorized use by a
password.
Also, the service port provides access to the
parameters of the program which can be used to
optimize the functionality of the installation, (see:
“Parameter list”).
WARNING
For access to the parameters of the
program using the service port, always
use the special service port cable!
The special service port cable (Art. nr. 6147117698)
can by ordered separately.
5.4.3 Number of operating hours per pump
The current number of operating hours of a pump
determines which pump will be switched on or off
next. The pump with the fewest operating hours will
be switched on first and the pump with the most
operating hours will be switched off first. This makes
sure that all pumps have an equal number of
operating hours, including the backup pump.
5.4.4 Test run
In order to prevent pumps from standing still for a
longer period of time, an automatic test run procedure
is provided as a standard.
5.4.5 Functioning WSD-Sensor (option)
In combination with the Megacontrol, the WSD can
generate a failure message when, during a
(adjustable) period of time, insufficient refreshment of
the membrane switch vessel occurs.
The failure message is generated when:
•Insufficient refreshment occurs;
•The membrane of the membrane switch vessel
is defective;
•There is no air left in the membrane switch
vessel;
•The installation is not set / installed correctly.
5.4.6 Temperature-sensor (option)
When the Megacontrol is fitted with a temperature
sensor, it can generate a temperature-dependent
failure message.
Type Applications
WSD Installations with a maximum of 3
membrane switch vessels.
