Fuses protecting the transformer against short circuiting of the primary circuit and of its supply line.
FU1
FU1 = Electrical characteristics: 6,3x32 T 250mA
FU2
FU2 = Electrical characteristics: 5x20 T 100mA
Fuse protecting the transformer against incorrect connection of the motor cables (check the thermal
FU3
protection). The panel remains live even after intervention of the protection which interrupts
operation. Electrical characteristics: 6,3x32 T 250mA
Fuse protecting the electropump P1 against short circuiting.
FU4
Electrical characteristics: 10x38 16A (aM)
Fuses protecting the electropump P2 against short circuiting.
FU5
Electrical characteristics: 10x38 16A (aM)
Function (see references on the wiring diagrams)
Terminals N and R activate the alarm light on the front board of the Electric Panel;
they close the remote alarm contact and the terminal N stops the pump while the
terminal R starts or stops the pump depending on the function chosen
(pressurisation, filling, draining).
The controls A, B, C, R, N do not require connection to
to the PELV safety circuit.
= power supply output for sensor: 24V, max 100mA.
= input characteristics: 4...20mA with DS_B7 in ON / 0.5...4.5V with DS_B8 in ON.
= characteristics: 0V.
NO Contact with panel fed and with no active alarm.
For 400V power supply insert the fuse FU1 in the 400V fuse holder.
For 230V power supply insert the fuse FU2 in the 230V fuse holder.
Selecting the wrong fuse holder can cause irreparable damage to the electric
panel!
