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.
5.6.4 - GI: Integral gain coefficient
In the presence of large falls in pressure due to a sudden increase of the flow or a slow response of the system, increase the value of GI. Instead,
if there are swings in pressure around the setpoint value, decrease the value of GI.
IMPORTANT: To obtain satisfactory pressure adjustments, you generally have to adjust both GP and GI.
5.6.5 - RM: Maximum speed
Sets a maximum limit on the number of pump revolutions.
5.6.6 - NC: Simultaneous devices
(4)
Sets the maximum number of devices that can work at the same time. It may have values between 1 and the number of devices present (max 2).
By default NC assumes the number of active devices, which means that if active devices are added or removed, NC assumes the value of the
devices present. Setting a value other than the active devices fixes the maximum number of simultaneous devices at the number set. This
parameter is used in cases where there a limit on the pumps you can or want to be able to keep running (see 5.6.7 IC: Configuration of the reserve
and the examples below). On the same menu page you can also see (but not change) the other two system parameters linked to this: the number
of devices present, detected automatically by the system, and the number of active devices.
5.6.7 - IC: Configuration of the reserve
(4)
Configures the device as automatic or reserve. If set on auto (default) the device participates in normal pumping, if configured as reserve, minimum
starting priority is associated with it, this means that the device with this setting will always start last. If a number of active devices is set that is
one lower than the number of devices present and if one element is set as reserve, the effect obtained is that, if there are no problems, the reserve
device does not participate in regular pumping; instead, if one of the devices that participates in pumping develops a fault (maybe loss of power
supply, tripping of a protection, etc.), the reserve device will start.
The state of configuration as a reserve can be seen as follows: on the Multi-pump System page, the top of the icon is coloured; on the main page,
the communication icon representing the address of the device appears with the number on a coloured background. There may be more than one
device configured as reserve in a pumping system.
Even though the devices configured as reserve do not participate in normal pumping, they are nevertheless kept efficient by the anti-stagnation
algorithm. The anti-stagnation algorithm changes the starting priority once every 23 hours and allows the accumulation of at least one continuous
minute of supply of flow from each device. The aim of this algorithm is to avoid the deterioration of the water inside the impeller and to keep the
moving parts efficient; it is useful for all devices and especially for those configured as reserve, which do not work in normal conditions.
