Rif.
FU3
Fuses protecting the auxiliary circuit against incorrect connection of the motor cables (0.2A).
The panel remains live even after intervention of the protection device which interrupts operation.
FU4
Timer for regulating the strong static torque time. Possibility of regulation from 0.5 to 4 sec. set by the
KT1
manufacturer during calibration at 2 sec. (only for ED 3 M HS ).
CL1 Module controlling the level probe (where present) for protection in the event of water presence in the OIL
chamber of the pump seals.
Standard in three-phase panels with star-delta start.
Possibility of fitting in three-phase panels with direct start.
QM1 Automatic magnetothermal switch, for protection of the P1 motor supply line against overloads and short
circuits, with manual reset.
QS1
Supply line insulating switch with door locking handle which may be padlocked.
14
Spare fuses for FU3 or FU4 (0,2A).
Connection terminals for the water minimum/maximum level control float.
A
Contact characteristics: 24V a.c. 37mA.
1 - 2
Connection terminals for the minimum level (A - Stop level) maximum level (B - start level) control floats.
A + B
Contact characteristics: 24V a.c. 37mA.
1 - 2 __3 - 4
S
24V a.c. connection terminal for electric probe controlling the pump oil chamber.
Maximum resistance of electric probe 80 kohm or less (connect to the pump OIL sensor).

P
Connection terminals for the alarm float. Contact characteristics:  8 Amp; 250V.
25 - 26
Connection terminals for the remote alarm for indicating intervention of the alarm float.
Q
Contact characteristics: without potential, NO (normally open);  8 Amp; 250V.

Function (references on the enclosed wiring diagrams booklet)
= electropump P1 is manually controlled by the operator as long as the impulse
is maintained.
= electropump P1 is controlled directly by the floats or thermostats and zone
valves.
Function (on wiring diagrams of each model on page 58)
Disconnect the power before maintenance.
Set on QM1 the current indicated on the motor data plate.
Controls A, B do not require connection to
PELV safety circuit (CEI EN 60204-1)
Any intervention of the panel protections do not exclude the float function.
Connection of motor thermal protector.
ATTENTION! For pumps with KK thermal protector, please remove the
connector for KK clamps of the control panel and connect them with
protection cables which are present on the pump cable.
