machines, the procedure ends and a pop-up appears on each machine saying "association
not possible". An association may not be possible because the device you are trying to as-
sociate is already present in the maximum number or because the device to be associated
is not recognised. In the last case repeat the procedure from the start.
The search status for association remains active until the device to be
associated is detected (irrespective of the result of association); if not device can be seen
within the space of 1 minutes, the machine automatically
leaves association status. You can leave the search status for wireless association at any
time by pressing SET or MODE.
Disassociation of devices
To dissociate a device belonging to an existing group, go to page AS (installer menu) of the
device itself and press the ˅ key for at least 5 seconds.
After this operation all the icons related to the connected devices will be replaced the
message "No Dev" is shown and the COMM led will remain off.
Replacing devices
To replace a device in an existing group it is sufficient to dissociate the device to be repla-
ced and to associate the new device as described in the
procedures above.
If it is not possible to dissociate the element to be replaced (faulty or not available), you will
have to carry out the disassociation procedure for each
device and create a new group.
5.5.5 - EK: Setting the low pressure function on suction
Present only in models with Kiwa function.
Sets the low pressure function on suction.
Value

5.5.6 - PK: Low pressure threshold on suction
Present only in models with Kiwa function.
Sets the pressure threshold below which the block is tripped for low pressure on suction.
Function
disabled
enabled with automatic reset
enabled with manual reset
5.5.7 - T1: Low pressure delay (function detecting low pressure on suction)
Sets the time when the inverter switches off after detecting low pressure on suction (see
Setting low pressure detection on suction par. 7.6.15.5).
T1 can be set between 0 and 12 s. The factory setting is 2 s.
5.6 - Technical Assistance Menu
Present only in models with Kiwa function.
Advanced settings to be made only by skilled personnel or under the direct control of the
service network.
From the main menu, hold down simultaneously the "MODE" and "SET" keys until "SP"
appears on the display (or use the selection menu pressing ˄ or ˅). The menu allows
you to view and modify various configuration parameters: the MODE key allows you to
scroll through the menu pages, the ˄ and ˅ keys allow you respectively to increase and
decrease the value of the parameter concerned. Press SET to leave this menu and return
to the main menu.
5.6.1 - TB: Water lack blockage time
Setting the reaction time of the water lack blockage allows you to select the time (in sec-
onds) taken by the device to indicate the lack of water.
The variation of this parameter may be useful if there is known to be a delay between
the moment the motor is switched on and the moment it actually begins to deliver. One
example may be a plant where the suction pipe is particularly long and there are some
slight leaks. In this case the pipe in question may be discharged and, even though water is
not lacking, the electropump will take a certain time to reload, supply the flow and put the
plant under pressure.
5.6.2 - T2: Delay in switching off
Sets the delay with which the inverter must switch off after switch-off conditions have been
reached: plant under pressure and flow rate lower than the minimum flow.
T2 can be set between 2 and 120 s. The factory setting is 10 s.
5.6.3 - GP: Proportional gain coefficient
Generally the proportional term must be increased for systems characterised by elasticity
(for example with PVC pipes) and lowered in rigid systems (for example with iron pipes).
To keep the pressure in the system constant, the inverter performs a type PI control on
the measured pressure error. Depending on this error the inverter calculates the power
to be supplied to the motor. The behaviour of this control depends on the set GP and GI
parameters. To cope with the different behaviour of the various types of hydraulic plants
where the system can work, the inverter allows the selection of parameters different from
those set by the factory. For nearly all plants the factory-set GP and GI parameters are
