SP: Setting the Set Point pressure (only in pressure boosting and in KIWA pressure boosting with pressure
sensor)
Pressure Set Point at which the Ebox keeps the plant under pressure. It can vary between 1 bar (14 psi) and the full-scale value of the
sensor minus 2 bar (28 psi).
RP: Setting the Pressure Differential (only in pressure boosting and in KIWA pressure boosting with pressure
sensor)
Pressure differential in which the Ebox panel maintains the pressure in the plant. See chapter on pressure boosting.
It can vary between 5% and 95% of SP. SP + RP cannot exceed the full-scale value of the sensor. See chapter on pressure boosting.
HC: Pump P2 starting level (only in drainage or filling with depth sensor)
Starting level of pump P2.
HB: Pump P1 starting level (only in drainage or filling with depth sensor)
Starting level of pump P1.
HA: Pumps stopping level (only in drainage or filling with depth sensor)
Stopping level of pumps P1 and P2.
9.4.4 INSTALLER MENU
From the main menu, hold down simultaneously the "MODE" and "SET" keys until "INSTALLER MENU" 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.
Also in this menu, different parameters may be seen depending on the operating mode.
RC: Setting the rated current of the electropump
Rated current absorbed by the pumps in Ampere (A). The rated current of the pumps used must be set. The rated current refers to the
type of connection used, star or delta or single-phase. If 2 pumps are used, they must be identical.
MF: Operating mode
This parameter expresses the operating mode of the Ebox. KIWA pressure boosting mode is available only if the language selected is
Dutch, French or English. If the operating mode is changed, the wizard starts automatically with the request for the parameters that
have not been configured.
MC: Control devices
This parameter allows you to choose the type of inputs that inform the Ebox about the system status. The inputs may be floats, level
probes, pressure sensors or depth sensors, depending on the type of application.
GS: Protection devices (only in drainage or filling or with depth sensor)
This parameter allows you to choose the type of inputs that inform the Ebox about anomalous conditions of the system. The inputs
may be floats, level probes or the depth sensor.
PR: Type of sensor used (only if a pressure or depth sensor is used)
This parameter allows you to choose the type of sensor connected to the Ebox.
MS: Measuring system
This parameter allows you to choose the type of measuring system used to express the values on the display. The values may be
expressed with the metric system or with the imperial system.
SO: Dry running factor
Sets a minimum threshold of the dry running factor below which the lack of water is detected. The dry running factor is a non-
dimensional parameter obtained from the combination of the absorbed current and the power factor of the pump. Thanks to this
parameter it can be correctly established when a pump has air in the impeller or when the intake flow is interrupted.
If you want to use this type of protection against dry running, the parameter TB (block time for lack of water) must be set at a value
other than zero.
To set the SO threshold, it is recommended to perform the following tests (with parameter TB at 0):
run the pump at a low flow rate and memorise the SO value read
•
run the pump dry.
•
Set TB at the desired value and set SO halfway between the 2 values read in the 2 previous situations.
MP: Minimum pressure threshold (only in pressure boosting and KIWA pressure boosting)
Sets a minimum pressure for switching off due to water lack. If the pressure in the plant arrives at a pressure below the MP, the water
lack signal is given. This too requires a TB value other than 0 to be active.
OD: Expansion vessel size (only in pressure boosting and KIWA pressure boosting)
Allows you to set the size of the expansion vessel.
EP: Pump exclusion
Allows you to exclude one or both pumps; useful if only one pump is connected to the Ebox panel.
9.4.5 TECHNICAL ASSISTANCE MENU
From the main menu, hold down simultaneously the "MODE" and "SET" and "-" keys until "TECHNICAL ASSISTANCE MENU" 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. Also in this menu, different
parameters may be seen depending on the operating mode.
