The sequence of construction of the wall block spray system
1. Pipeline construction: the main waterway switch is set at the starting point, the main road is set at 4 metres, three connections to the two end pipes are required, a spray pipe is inserted above, and a direct nozzle is installed at the top. (the distance between the spray tubes may be set as needed) the pipes are fixed by the clamps and screws。
2 pump installation: first, the pump needs to be attached to the frame with screws, and when the power lines are connected, the shelter will be covered with the pump, and it will be fixed with screws. Pumps will be tied to the pump with screw cards, following the living ribbon. The pump and the other end of the pipe will also need to be linked to the pipe by a live ribbon。
3. Smart controls have good waterproofing set-up, which can only be fixed to the fence. The inner line of the controller is fully connected to the power line, the device line, the water level reporting line and the pump power line。
4. Connect controls to each other so that they can be used。
Attention provided to site perimeter spray system installation
Water pumps:
A. Fill the pumps with water before they start
B. Water valves must be opened on start-up to reduce the start-up load of the electric power and avoid burning down the electric power
Controllers:
A, fix the controller, hold the wall, open the switchbox, click on the label to match the power and pumps
B. Connecting to the chart in the statement according to demand. The wires cannot be short-circuited and can not be attached to the wells; when the signal lines are extended (not more than 0. 75 mm2 is recommended for extension), please complete with waterproof tape
Attention to the use of the wall spray system
1. Turn on: when all lines are connected, the air switch is closed, the start key is pressed when the working mode is selected and the pump is activated. Attention
Controls are automatic, manual, and three working mode options: a. In automatic mode, if the start button is not pressed, the automatic mode light blinks and the controller does not run automatically. The controller can only run automatically when the automatic mode light is on. B. Press the start or stop key in manual mode, and the controller initiates and suspends the power. In manual mode, this control only protects overloads, missing phase, from water level or pressure, and empty loads。
3. Lack of protection: any one of the three-phase power loads is suddenly disconnected, and this shield will cut the pump power within three seconds。
4. Pressure protection: when grid voltage is less than 300 v, this controller will cut the pump power within 20 seconds. The phenomenon shows the same values for voltage and current meters, with no phase indicator light。
