CONSTANT PRESSURE CONTROLLER
SPECIFICATIONS
Pressure Transmitter:
Input Voltage DC20-24v,
Output votage DC0-10v
Amperage 110Ma
Pressure range 0~14kg
Pressure stability 96% FOS
Digital display:
Adjustable Pressure setting:
A wide range 25 turns of peressure settings is available through the use of the luck control system. The desired pressure is easily established by means of a”set screw”;clock-wise increases pressure , counter clock-wise decreases the pressure.
CPU maintains and compensates the pressure.
PROTECTION INDEX IP 68 water and dust proof.
■WATER IN NORMAL USE.
The controller will start the motor at 90% of pre-set pressure in order to boost/maintain the desired pressure.
■MOTOR STOP MODE
When the water tap turned off, the green indicator light turns on , showing the controller is in the “motor stop” mode. If the mode laste 20 seconds the motor will stop auto matically.
■LEAKAGE DETECTION
The controller continuously monitors water pressure and if pressure is under 80% of the pre-set level (duc to leaks).it will start the pump to compensate for the pressure.
■NO WATER AND LOST PRESSURE PROTECTION
When the motor is at full speed and cannot achieve at least 60% of the pre-set pressure , then there is either(a) no incoming water supply or (b) the impeller has failed. The red indicator light illuminates and, after 20seconds, the motor will automatically stop. Turn off electricity, solve the problem and restart after 15 seconds.
All the above mentioned functions integrate in one unit, protected by metal shell, simplify the conneetion and ,no magnetic wave interference.
INTERFACE CONTROLLER
FEATURES
·With DC24v inter power supply controller
·One input,two outputs for inverter to control variable motor Speed.
·Automatically monitors the water pressure,enables the pump Systerm to operate alternatively and parallelly,the controller Always stars the primary pump, then, after 60 seconds, if the Primary pump is not sufficient to reach the pre-set pressure Level, the secondary pump is brought on-line by the controller.
(This process continues depending upon the number of
Pumps in the systerm.)
·When water consumption is reduced,the controller will instruct The motor to decrease motor speed or bring the secondary pump Off-line.
·If any pump failed,will alter to other pump automatically.
·The designated primary pump is altered every 4 hours by the Controller, that is, the secondary pump becomes the designated Primary pump, and so on; therefore reducing, individual motor Use and extending motor life.
·Constant pressure in the piping , quiet running smooth speed Changing, No water hammer.
◆Space saving:
Use vertical multi-stage pumps, small pressure tank.
◆Simple wiring, perfect production functions:
One pump one inverter,soft start, soft stop. Over-load, over-heat, high/low voltage,reverse rotation, sudden power off……ect. Protection.
◆Ideal control box construction:
Dust free, no ventilation fan, energe saving .
◆Single chip,single point, single part control:
Minimize the defect possibility, easy maintainance.
DESIGNED PATENTED INVERTER PROVIDES:
Low noise(52db),gentle start/stop of motor ,low starting current, elimination of“water hammer”and greatly reduced vibration.
The inverter causes the system to consume less energy than most other units.
