The following I/Os are used for BERMAD’s waterworks and Irrigation
Applications:
DC Solenoid:
Connect the solenoid’s wires to the cable coming out of the
controller’s first station port. Connect the solenoid’s RED wire to the
controller’s RED wire and the BLACK wire to the controller’s BLACK
wire.
Power supply:
Open the battery’s compartment lid and connect a good-quality 9
Volt alkaline battery, then firmly close the lid.
When the battery is first connected, the controller performs a self-
test, closes the DC solenoid and displays the first settings screen.
Under normal use, the battery should last for at least one season.
Hydrometer or Water Meter:
BERMAD’s 900 series Hydrometer, or a water meter with dry contact
pulse output, is used in applications such as the following:
n
n
Pressure management with flow rate reference applications
where switching to the high pressure setting is done in case of a
high demand for water.
n
n
Pipes’ dead-end purging applications where the purged-out water
is measured by volume and not by time.
n
n
In cases of fire protection or volumetric irrigation applications.
Connect the two water meter pulse wires to the two controller’s
RED wires. Please note that there is no polarity significance in this
connection.
