Description
BAC901 SERIES AUTOMATIC BACKFLUSHING FILTRATION CONTROLLER
BAC901 series automatic backflushing filtration controller is equipped with built-in computer microchip. Automatic backflushing control system is made up of the solenoid valve, three-way backflushing valve, filter units, hydraulic sensor, alarm, pressure sustaining valve, water pump and so on, which are linked by the programming software through input and output signals of controller. It can automatically take turns to clean each filter online. Meanwhile, it can uninterruptedly provide filtration water. So it achieves the purpose of unmanned automatic control. The controller is equipped with LCD which can show real-time operation status of equipment.
TYPICAL APPLICATION
Apply in backflushing disc filter, to form automatic backflushing disc filter system;
Apply in sand media filter, to form the automatic backflushing sand media filter system;
 
THE MAIN FUNCTION
*The controller can be set three kinds of backflushing trigger modes: timing trigger, inlet and outlet pressure difference
trigger and manual trigger;
*The controller is equipped with a differential pressure sensor and water pressure connecting port for inlet and outlet,
which can determine immediately the difference of water pressure;
*It is embedded DP sensor zero calibration, when calibration, it is needed to disconnect the water pipe;
*When disconnecting embedded sensor, it can also be triggered by an external differential pressure sensor after entering
a dry contact signal;
*The controller can separately count the number of backflushing cycles triggered by DP, by time and manually;
*The controller can be set the times of backflushing cycle triggered by differential pressure. When the times of
backflushing cycle triggered by the differential pressure exceeds the preset times, the backflushing will be stopped
and give an alarm. The alarm problem will be displayed on the screen. The differential pressure could not trigger
backflushing, and the subsequent backflushing will only be triggered by the timer start;
*The controller can output an external alarm signal which used to alarm infinite cycle backflushing happened;
*The controller can output a control signal of the main pressure sustaining valve (or on-off valve);
*The controller can set whether the pressure sustaining valve is working and delay the opening time of backflushing
valve after the pressure sustaining valve starts to work;
*The controller is equipped with customized LCD screen and keyboard for users, which can interact and reflect the
real-time running status of the equipment. The display interface is designed user-friendly and its operation is simple
and easy;
*The user can set the backflushing time, the delay time between the backflushing valves and the delay time of the
differential pressure detection flexibly;
*Modular design can automatically detect the output module of the controller, and expand the number of filter units flexibly;
 
FEATURES
*Integrated structure design, IP65 protection level;
*DC 6V battery and AC 110V/220V both power supply modes are available;
*The DC-powered controller can be powered by four 1.5V batteries and can be connected to control multiple DC 12V
self-locking solenoid valve;
*The low voltage alarm will be displayed on screen display when the battery voltage is low;
*The AC-powered controller includes a transformer that can convert 110v or 220v to AC 24 V, and is connected to control
multiple AC 24V solenoid valve;
*Modular design are available for 2, 4, 6, 8 and 10 filter units;
*According to the number of filter units in the system, the corresponding model can be flexibly chose for control valve station;
*The controller can automatically detect and display the output number of backflushing valve stations;
