upon the fourth to signal the activation of the no. 1 motor amperometric and/or phase failure
protection.
Green indicator light (LED): it comes on to signal that the pump is running.
LL5
Red indicator light (LED) which flashes upon the first three activations and comes on steady
upon the fourth to signal the activation of the no. 2 motor amperometric and/or phase failure

protection
LL7
Yellow indicator light (LED) which comes on when the current absorbed by motor no. 1 exceeds the current
value set in AMP1.
LL8
Yellow indicator light (LED) which comes on when the current absorbed by motor no. 2 exceeds the current
value set in AMP2.

AMP1 Adjustment of motor no. 1 amperometric protection (ON THE AMPERE SCALE, SET THE RATED
CURRENT VALUE FOR THE MOTOR TO BE PROTECTED, AND MAKE SURE THAT THE LL7
YELLOW LED REMAINS OFF UNDER ALL MOTOR LOAD CONDITIONS).
When the protection is tripped, the power to the motor is cut off; this condition is signalled by the LL4 LED and
by the remote control contact (upon fourth activation only). The protection tripping times range from a
minimum of 5 seconds to a max of 40-60 seconds.
AMP2 Adjustment of motor no. 2 amperometric protection (ON THE AMPERE SCALE, SET THE RATED
CURRENT VALUE FOR THE MOTOR TO BE PROTECTED, AND MAKE SURE THAT THE LL8
YELLOW LED REMAINS OFF UNDER ALL MOTOR LOAD CONDITIONS).
When the protection is tripped, the power to the motor is cut off; this condition is signalled by the LL6 LED and
by the remote control contact (upon fourth activation only). The protection tripping times range from a
minimum of 5 seconds to a max of 40-60 seconds.
KL1 card protection fuses against electronic circuit short circuiting, type 5x20 from 0.25 to DELAYED.
FU1
FU2 M1 - M2 motor power supply line protection fuses, against short circuits, as indicated in chapter 6.2.
FU3
When the protection is tripped, power to the motor is cut off.
KL1 Electronic board for automatic changeover of the starting order of the electric pumps, motor protection and signal
management.
Supply line insulating switch with door locking handle which may be padlocked.
QS1
PS MIN Terminals for connection of minimum pressure switch and dry running float switch.
1 - 2 To use, remove jumper.
Input characteristics: 12 V d.c. 0.005 A (use the pressure switch NO contact).
PS. 1 Terminals for connection of electric pump no. 1 pressure switch or ON/OFF float switch.
3 - 4 Input characteristics: 12 V d.c. 0.005 A .
Terminals for connection of electric pump no. 2 pressure switch or ON/OFF float switch.
PS. 2
Input characteristics: 12 V d.c. 0.005 A.
5 - 6
The controls do not require connection to
safety circuit PELV (CEIEN 60204-1).
OUT. Terminals for connection of a remote alarm for signalling the following activations:
7 - 8 - 9
- AMP1 and/or AMP2 (upon fourth activation).
- MINIMUM PRESSURE.
- Tripping of FU1 and/or FU2 fuses.
Contact characteristics, 5 A 250 V.
Potential-free NO contact to signal tripping of AMP1 and/or AMP2 FU1 and/or FU2 and PSMIN.
ENGLISH
= the electric pump is controlled manually by the operator.
0 = the electric pump is excluded from any command.
= the electric pump is controlled by the pressure switches or float
switches PS1 – PS2.
