The connection of the alarms can distribute power even
when the frequency converter is turned off. Ensure that
there is no residual voltage on the terminals of the alarms.
z
All the power terminals and other terminals must be
accessible after installation is completed. The maximum
output frequency must not exceed the design frequency of
the pump being controlled. Operating at a frequency
higher than the allowable frequency can cause higher
current absorption and damage to the device.
z
If it is necessary to remove the frequency converter, remove
only the covers required in order to disconnect the
electrical cables. Take care not to damage the electronic
cards.
z
Failure to comply with the safety regulations not only
causes risk to personal safety and damage to the
equipment, but also invalidates the warranty.
This pump set is controlled with two linked pump controllers, the controllers
allow the system pressure to be set on the digital display. The pump speed will
be varied by the controllers to maintain the set system pressure (Constant
pressure mode), if the set system pressure cannot be maintained with one pump
running, the second pump will automatically be started to increase the system
pressure to the set pressure (Duty/Assist).
Both controllers are electronically linked (Master and Slave) this allows the
pressure set on the master controller to be used for the slave controller,
simplifying the setting process. The master controller is the left hand unit and
will be confirmed when switching the unit on, the
icon will appear
permanently on the master display panel.
