Presscontrol

 -functioning:The starting operation archived, the unit is programmed to perform all the pump control operations automatically.When particular operational breakdowns occur, such as water failure, obstructionof the suction pipe, etc, the unit recognizes the breakdown and red led Failure lightis up, at the same time a stop signal is sent to the pump to present damages caused by its working in the absence of water. Rectification of the failures that have caused the blockage, allows the system to be restarted by pressing the resent button.
-Instructions for installation
-The single operating steps of the system are displayed by indicatorlights on a small panel at the front of the control box.
-Tow of these will light up when the Presscontrol is connected to the electrical power supply:Power On(green)and Pump On(yellow),indicating that the circuit is powered up and the pump is running (see fig 1).The pump will continue to operate for a few seconds,so that pressure can be established in the system.
-At this pointthe pump will be shut off and seitched to the standby condition(green light on),ready to respond to the various monitoring and control signals generated by the system(fig 2)
-Whenever a tap orvalve is opened at any point of use, the pump will be activated immediately by the Presscontrol unit and continue to run as long as the relative outlet remains open(fig1)
-When the outlet is closed, the Presscontrol unit shuts off the pump, returens the system to maximum pressure and reverts to the standby condition (fig 2).
-Any irregular operating conditions, such as a dry or blocked inlet line, etc., is recognized by the Presscontrol and indicated by the Presscontrol and indicated by a Failure light(red);the pump will be shut off immediately.Once the cause of the trouble has been removed, the user need only press the red Restart button to restore normal operation (fig 3).In the event of a power cut, the Presscontrol system will reset and restart automatially when power if restored.
