Set the automatic magnetothermal switches QM1–QM2 following the
indication of current absorbed in the electrical data plate.
QS1
Supply line insulating switch with door locking handle which may be padlocked.
A
Connection terminals for the minimum level control float (for use only in systems with 3 level control floats
plus an alarm float if required).
-
1
2
Input characteristics: 5V d.c. 2.5mA with module SZ2 switched on.
B
Systems with two floats (B+C): Connection terminals for the float (minimum/maximum level control of
electropump P1 and minimum level electropump P2) and for the thermostat or zone valve for circulating pumps.
3 - 4
Systems with three floats (A+B+C): Connection terminals for the maximum level control float of
electropump P1.
Input characteristics: 5V d.c. 2.5mA with module SZ2 switched on; 24V a.c. 0.5A with module SZ2
excluded.
C
Connection terminals for the maximum level control float of electropump P2 and for the thermostat or zone
valve for circulating pumps.
5 - 6
Input characteristics: 5V d.c. 2.5mA with module SZ2 switched on; 24V a.c. 0.5A with module SZ2
excluded.
Connection terminals for the dry alarm float. If used, remove the by-pass jumper which is a standard fitting
N
between terminals 21 and 22.
21 - 22
Input characteristics: 24V a.c. 40mA.
Controls A, B, C, N, R do not require connection to
connected to the PELV safety circuit (CEI EN 60204-1).
O
Connection (standard feature) for selecting operation of module SZ2 for drainage pumps; with the jumper
excluded, module SZ2 is set to operate for circulating pumps and booster sets.
23 - 24
P
Connection terminals for the alarm float. Contact characteristics: ≤ 8 Amp; ≤ 250V.
25 - 26
Any panel protection interventions do not exclude the float function.
Q
Connection terminals for the remote alarm for indicating intervention of the alarm float.
Contact characteristics: without potential, NA (normally open); ≤ 8 Amp; ≤ 250V.
31 - 32
R
Connecting terminals of the pressure switch for maximum pressure P.MAX.
If used, remove the by-pass jumper supplied as a standard feature between terminals 35 and 36.
35 - 36
Input characteristics: 24V a.c. 40mA.
U-V-W
Connection leads for the electropump P1/P2 for panel types E2D 2 T, E2D 3 T.
Scrupulously respect the required correspondence.
Ref.
U-V-W
Connection leads for the electropump P1/P2 for panel types E2D 5 T, E2D 8 T, E2D 15 T,
E2D 16 T, E2D 30 T SD, E2D 40 T SD.
Scrupulously respect the required correspondence.
K-K
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 (pag. 118).
FU1
Fuses for protecting the transformer against short-circuits of the primary circuit and of its supply (1A).
FU2
Intervention inhibits all the panel functions and switches off indication HL1.
It does not inhibit the function of the alarm float (if there is one connected to
the P terminals) and the respective remote alarm (connected to the Q
terminals)
FU3
Fuses for protecting the transformer against incorrect connection of the motor cables (0.2A).
The panel remains live even after intervention of the protection device which interrupts operation.
Disconnect the power before maintenance.
