JMDM-2011 is an industrial controller with strong functions, stability and reliability, and strong anti-interference ability in the industry. It has a very high cost performance and has greatly improved the customer's production efficiency and economic efficiency. It has won domestic and international performance with excellent performance. The trust of many customers, and establish a solid long-term win-win cooperation. At present, it has been widely used in high-speed, high-precision analog input and output, digital input and output applications such as cylinders, solenoid valves, relays, stepping and servo motors, proportional valve control, and inverter control. Has been successfully used throughout the country, weighing filter, roller feeder, automatic water dispenser, bag making machine, punch feeder, crusher, printing machine, cutting machine, compactor, pressure tester, hydraulic control Equipment, laser controllers, multi-channel temperature controllers, etc. require high-precision, high-speed control of the occasion or equipment, and are exported to overseas.
First, the water control part of the low pressure valve in the case of the low pressure valve signal is turned on, if the low pressure valve is not connected, then stop the water. Turn on the power supply system water pump to start, and start the flushing solenoid valve at the same time, stop the host and stop flushing if no water shortage signal is detected after the start of 90 seconds. If a water shortage signal is detected, stop flushing until the water is full. Flush the solenoid valve for 30 seconds every 90 minutes during the water. Every time a water shortage signal is detected, the water pump is started and flushed every 90 minutes for 30 seconds (preferably, the flush time is adjustable within 60 seconds).
Pump specifications and parameters: voltage AC220V current 7A
Solenoid valve specifications and parameters: voltage DC24V.
2. Control of the ozone generator Turn on the power to start the ozone generator for 10 minutes, and then start the ozone generator for 90 minutes every 8 hours. (It is best to adjust ozone opening time within 60 minutes).
Ozone machine specifications and parameters: voltage AC220A current 1A
Third, the coin acceptor bills two coin acceptors, and the separate accesses do not interfere with each other. Each pulse represents a 0.1 yuan (or 0.5 yuan or 1 yuan) dial switch. For each 0.1 yuan purchase 0.5 liters or 1 litre to convert the amount of water conversion dial switch.
Coiner specifications and parameters: power supply is DC12V, pulse signal, pulse letter and power supply common ground.
When the low level of the water tank is switched on, the power supply to the coin dispenser is turned off, and when the low tank level of the tank is disconnected, the power supply to the coin acceptor is switched on.
4. There are two solenoid valves in the pumping operation. Each solenoid valve has one outlet button and one pause button. The low level in the water tank is not switched on. After the coin is coined, press the water button to turn off the water, and press the pause button to stop the water. After paused for 3 minutes, the display returns to 0 and returns to the initial screen. When the water flows out, the flow meter measures. When the water is over, it stops automatically. The display returns to 0 and returns to the initial screen. The flow meter is a pulse signal of a Hall element. Every 29 pulses represent 1 litre of water. Voltage DC24V, power 2 wires, signal 2 wires. If the fault bit signal turns on during the drawing process, the coin power supply power-off coin stops trading, but the failure screen is not displayed until the transaction is completed.
Draw water solenoid valve specifications and parameters: DC-24V
5. Fluorescent and water-saving lights control the fluorescent light with the light control signal control, 24:01 - 17 o'clock every day, light off, 17:01 - 24:00 light. The water light is on the premise that the fluorescent light is on, the coin light after the coin is on, and the water light is delayed by 20 seconds when the display is zero.
Draw light DC12V.
Sixth, liquid crystal display
1. In the initial screen, when the water system is normal and no one is trading, the “Welcome to Welcome†character is displayed with a height of 20 mm. It is displayed below the welcome screen. “Emergency Drinking Water is 0.X per litre. The price corresponds to the dial switch.
Welcome to Jingmin Drinking Water for 0 liters per liter
2. After the coin screen is displayed on the transaction screen, the display screen amount of water is 000.0 000.0.
3. Fault screen failure Do not insert coins Cause of failure Causes: 1. Water shortage 2. Water pressure is low (water pressure is not immediately displayed, and the fault screen is displayed together with water shortage)
4. The data screen displays the accumulated revenue under the trigger of the button. The income is 100.000000 00000.0.
It is used to read the accumulated data and this time into the machine currency data.
For example, in the normal business condition, it is displayed as "Welcome, 0.2 yuan per liter for the sensitive drinking water".
If you press the half-price button in advance, it will be displayed as "Welcome, 0.1 yuan per liter for a straight drink."
After inputting five cents, it is displayed as "amount of 0.5, amount of water 2.5"
If you press the half-price button in advance, it will be displayed as "amount of 0.5, amount of water 5.0"
During the release of water, the amount of water is not changed, but the amount of water decreases with the discharge of water until it drops to 0
VII. There is a screen display indicator on the circuit board for suspension of sale and operation. When the water tank is short of water (at a low water level), the LCD screen displays the shutdown screen;
When there is water in the tank and it can be normally opened, the LCD screen displays the operation screen.
8. Externally provide DC-24V, 12V two-way switch power supply.
