IMPORTANT: The regulating parameters GP and GI also change in the two configurations. In addition the GP and GI values set in mode 1 are
stored in a different memory from the GP and GI values set in mode 2. So, for example, when passing to mode 2, the GB value of mode 1 is
replaced by the GB value of mode 2 but it is kept and will reappear again when returning to mode 1. The same value shown on the display has a
different weight in one mode or in the other because the control algorithm is different.

5.5.3 - MS: Measuring system

Set the measuring system, choosing between metric and Anglo-American units. The quantities displayed are shown in Table 13.
NOTE: The flow in Anglo-American units (gal/min) is indicated adopting a conversion factor of 1 gal = 4.0 litres, corresponding to the metric gallon.
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.
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.

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. 5.7).
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 seconds) 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 optimal. However, should any problems occur in
adjustment, these settings may be varied.
