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: Pressure management with flow rate reference applications where switching to the high pressure setting is done in case of a high demand for water. -

Page 8: Switching The Controller's Operation Modes
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. -

Programming Steps Basic Settings: Setting Flow Reference Set-point Upon entering to this screen the display shows the [SP:PH] (Set Point : Pulses per Hour) title. Use the or the buttons to set the flow-rate value by number of pulses per hour. This is the flow-rate that Fig.1 - Flow set-point distinguishes between high and low pressure conditions. - Page 12 Setting the High to Low flow stabilization delay timer Upon entering to this screen the display shows the [SP:tL] (Set Point : Low flow timer) title. Use the or the buttons to set the required delay time parameter which is used for verifying that the change from Fig.3 - Low flow timer High flow to Low flow is stable.

Note the icons change according to your selection: the icon should be selected for time operation. Factory default - Time. - Page 17 Flow switch mode: Press the button to enable or disable the flow switch operation. When a flow switch is enabled the icon appears on screen. Factory default - flow switch enabled.

Page 18: Application Description
Normally the high pressure pilot controls the valve, while the low pressure pilot is on standby mode. A BEC PM1 controller with a DC solenoid can switch the high pressure pilot with the low pressure pilot according to a pre-defined time based operation regime. - Page 19 For example, in typical municipal pressure regime, the day low pressure hours are between 10:00 AM and 06:00 PM and the night low pressure hours are between 10:00 PM and 06:00 AM, during the high demand hours the valve maintains the high pressure setting. Therefore, the three required program parameters of the controller are: Operation Time - 8 hours, Operation Days - 7 days and two Start Times one at 10:00 AM and the other at 10:00 PM.

Page 20: On/Off Control Application
Chapter #4 On/Off Control Application The BEC PM1 enables a volumetric or time based 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. This chapter describes the Dead-end Pipes Purging Application Settings. - Page 21 A. Purging interval by Days of the Week and purging amount by operation time: In this example the pipe needs to be purged for 5 minutes every Monday and Friday at 08:00 AM. Therefore, the three required program parameters of the controller are: Operation Time - 5 Minutes, Operation Days - Monday and Friday, and Start Time at 08:00 AM.
- Page 22 B. Purging interval by Days Interval and purging amount by operation time: In this example the pipe needs to be purged for 5 minutes every 10 days at 08:00 AM. Therefore the three required program parameters of the controller are: Operation Time - 5 Minutes, Operation Interval - 10 days and Start Time at 08:00 AM.
- Page 23 In order to operate this application the BEC-PM1 controller should be connected to BERMAD’s 900 Series Hydrometer or to another BERMAD control valve and to a water meter. The BEC PM1 controller should be also set to volumetric operation, which can be done only at the initial setup process of the controller (when power is connected or when the controller’s reset operation is performed).
- Page 24 and the operation stops. (See the fault messages paragraph in the monitoring chapter of this document.) The factory default is 60 seconds; use the and the buttons to set the required H.F.R. parameter. Press the button to move to the next water meter setup parameter.
- Page 25 set the required operation volume (050 pulses in our example). Press the button to move to the next programming screen which is the Operation Days screen. 2. Operation Days: Use the button to set a particular day as an operation day, the cursor advances to the next day.

Programming Steps This chapter describes the required programming steps of the controller and it is divided into two: Basic Settings and Irrigation management settings. Basic Settings: First Basic Settings Screen The basic controller setting should be done once the controller is wired to the system and the power is connected, or after a total reset operation is performed. - Page 28 88:24 Factory Default - DC Solenoid Clock Mode: 88:12 NOTE: This value can be set only after Factory default - 24h. power-up or full unit reset. Press button and set the system clock to 12 or 24 hour clock. Time / Volume Operation: NOTE: This value can be set only after power-up or full unit reset.
