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 termi-
nals B, COM and A as follows:
• COM: connect the ground wire (GND) of the
monitoring system.
• A: connect the other wire of the management
system. It Transmits pulses from main reed sensor.
• B (optional): the pulse generator is equipped
with two reed sensors, and if it is allowed by the
monitoring system, connect the third wire here.
