6.4 Water level sensing
To make the junction is necessary to follow carefully the instructions inside the kit.
At the time of joining and electrical connection is essential to maintain the
correspondence between the cables.
After cable joining and placed the pump in the well you must perform, before
connecting to power supply, a test of insulation: join together the two power cables
and, applying a voltage of 500V, an insulation resistance from the ground higher than
100 Mohm must be verified. Join together the two signal cables and, applying a voltage
of 500V, an insulation resistance from the ground higher than 100 Mohm must be
verified.
WATER LEVEL SENSOR
Water level sensing is based on
variation of measured
impedance. Keep it clean and
not in direct contact with pipes
in order to grant its function.
