The electrical connection scheme is shown in the following
figure:
MONITORING
SYSTEM
The electronic board LED allows quickly display of the
open (LED on) or closed (LED off) state of the solenoid
valve, if that is installed on the line.
Ensure proper connection to the positive and negative
poles of the electronic board. The power supply unit must
not exceed 30 V.
The monitoring system responsible for processing the
pulses generated will be connected to terminals B, COM
and A as follows:
• COM: connect the ground wire (GND) of the
monitoring system.
• A: connect the other wire of the management
team. It Transmits pulses from main reed sensor.
• B (opcional): the pulse generator is equipped with
two reed sensors, and if it is allowed by the
monitoring system, connect the third wire here.
