Introduction
This document provides installation and operation instructions for
the BEC PM1 controller as it is used with BERMAD’s control valves in
Waterworks and Irrigation Applications.
Very Important:
Chapter #1 of this document provides general installation and
operation instructions which are common to all the applications’
types while the rest of the chapters are organized by application
type.
Therefore before installing and operating this controller please read
carefully chapter #1 and then jump to the chapter related to your
specific application:
Pressure Management Applications:
Optimizing water supply and reducing non revenue water by using
the BEC PM1 controller is done by connecting it to BERMAD’s two
step pressure reducing valve installed at the entry point of a district
metering area.
Chapter #2
Pressure management according to flow rate:
For switching between the two pre-set pressure regimes of the PRV
according to high or low flow demand at the controlled district please
refer to chapter #2 of this document.
Chapter #3
Pressure management according to time
intervals:
For switching between the two pre-set pressure regimes of the
PRV according to time settings please refer to chapter #3 of this
5
document.
Chapter #4
On/Off Control:
The BEC PM1 enables a volumetric control of BERMAD’s On/Off
control valves that are used for purging pipe’s dead ends, refreshing
reservoirs and other such On/Off applications. Please refer to chapter
#4 if your specific application in of an On/Off type.
Chapter #5
Irrigation Control:
The BEC PM1 controller can be used as a single station irrigation
controller for agriculture or gardening. Please refer to chapter #5 if
your specific application is of an irrigation type.

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:
nnPressure management with flow rate reference applications
where switching to the high pressure setting is done in case of a
high demand for water.
nnPipes’ dead-end purging applications where the purged-out water
is measured by volume and not by time.
nnIn 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.

Flow Switch/Rain Sensor:
Flow switch can be used with the time controlled pressure
management application for switching to the high pressure setting in
case of a high demand for water, i.e. in case of fire.
Wiring Table:
The controller is supplied with the following wires connected to its
terminal strip:

Switching the Controller's Operation Modes
The BEC PM1 controller has two distinctive operation modes:
Irr mode - this is the default operation mode of the controller which
is used for Irrigation, Time Intervals Pressure Management and On/
off applications.
Pr mode - this mode is used for the Pressure Management according
to Flow-rate application only.
Switching between these two operation modes is done by
simultaneously pressing the and keyboard buttons.
For example:
Changing from “Irr” to “Pr” mode:
Press the and buttons simultaneously for 5 second, the
system displays the mode name and starts switching to the Pr
mode. Continue pressing the buttons for additional 3 seconds until
the software version appears on screen (in a form of a number)
then release the buttons. The controller is now on its “Pr” mode.
Please note that changing the controller’s mode requires about 10
seconds of continuous buttons pressing time in total.
Changing from “Pr” to “Irr” mode:
Keep pressing the and buttons for another 3 second,
the system displays the new mode name and switches back to
the Irr mode.
Important! Before operation the controller for the first time
make sure that it is set to the correct operation mode for your
specific application.

Background
This application enables the user to set a flow rate SET POINT in
number of pulses per hour. The application automatically changes
the control state of the Two Step Pressure Reducing Valve which is
controlled by the BEC PM1 controller according to the actual real-time
flow-rate reading.
When the actual flow rate reading crosses the SET POINT, the
controller starts counting a stabilization time delay parameter
for ensuring that the flow-rate crossing of the set-point is not a
temporary pressure fluctuation.
If by the end of the delay counting the flow-rate reading remains
beyond the set point the solenoid state changes.
There are two delay time parameters: One for LOW to HIGH flow
crossing of the set-point and the other for HIGH to LOW flow
crossing.
This application has four screens:
The first three screens are used for setting the SET POINT flow
reference [SP:PH] and the two values of the delay timers [SP:tH] &
[SP:tL].
The fourth screen is the automatic operation screen (“AUTO”) that is
used for monitoring the application operation.
