DAB E-BOX 2D M/T User Manual

ENGLISH
42
Ref. Function (see references on the wiring diagrams)
N
9 - 10
Connecting terminals against dry operation.
If used, remove the by-pass jumper supplied as a standard feature between the respective
terminals. Electrical characteristics: 24VAC 10mA, impendence max. 55kOhm.
If connecting with electric level probes, consider only Terminal no. 9
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 as they are connected
to the PELV safety circuit.
Terminals for connecting analog inputs
H1
11 - 12 - 13
Terminals for connecting the analog input for pressure sensor.
H1 –
11 = power supply output for sensor: 24V, max 100mA.
H1 –
12 = input characteristics: 4...20mA with DS_B7 in ON / 0.5...4.5V with DS_B8 in ON.
H1 –
13 = characteristics: 0V.
Terminals for connecting alarms
Q1
14 - 15
Terminals for connecting the electropump P1 remote alarm (see alarms table).
Contact characteristics: clean contact, 250VAC/30VDC 5A, double insulation (AC 1).
Q2
16 - 17
Terminals for connecting the electropump P2 remote alarm (see alarms table).
Contact characteristics: clean contact, 250VAC/30VDC 5A, double insulation (AC 1).
Q3
18 - 19
Terminals for connecting the general remote alarm (see alarms table).
Contact characteristics: clean contact, 250VAC/30VDC 5A, double insulation (AC 1).
NO Contact with panel fed and with no active alarm.
13 - 14
13 - 14
Connecting terminals for indicating pumps being fed (P1 and P2).
Contact characteristics: NO 250V 3A (AC 15)
Protection fuses
FU1
FU2
Fuses protecting the transformer against short circuiting of the primary circuit and of its supply line.
FU1 = Electrical characteristics: 6,3x32 T 250mA
FU2 = Electrical characteristics: 5x20 T 100mA
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!
FU3
Fuse protecting the transformer against incorrect connection of the motor cables (check the thermal
protection). The panel remains live even after intervention of the protection which interrupts
operation. Electrical characteristics: 6,3x32 T 250mA
Switch off power before performing maintenance.
FU4
Fuse protecting the electropump P1 against short circuiting.
Electrical characteristics: 10x38 16A
(
aM
)
Switch off power before performing maintenance.
FU5
Fuses protecting the electropump P2 against short circuiting.
Electrical characteristics: 10x38 16A
(
aM
)
Switch off power before performing maintenance.
