ELECTRIC PRESSURE SWITCH YEP-10K and YEP-20K
The electronic pressure switch is a product that perfectly complements the shortcomings of the existing pressure chamber for starting. Value can be measured more accurately with a digital display (up to 2 decimal places can be set), and installation in a narrow space is possible by minimizing the installation space. Unlike other products, it does not require a separate chamber and can be easily installed with a screw type. (KFI certified)

Advantages of Electronic Pressure Switch
• Easy and accurate pump start/stop setting (set up to 2 decimal places)
• Minimization of installation space
• Built-in terminating resistor
• A pressure gauge is required to display the pump discharge pressure X
• Using DC 24V power
• One switch can control 5 pumps
• Easy inspection and maintenance
• If the electronic switch is attached to the existing pressure chamber, it can be installed after removing the pressure gauge.
Caution
• Disconnection of DC 24V power during normal operation is prohibited.
• When setting the pressure, use the test valve after removing the air.
• If operation continues with automatic contact maintenance, etc., take necessary measures using contact relays, etc.
How to check
• Installation and storage in a dry place with low humidity
• When installing outdoors, treat it with a roof, etc. to prevent rain, and take measures to prevent freezing in winter.
• After installation, be sure to inspect it at least once a year.

Detail of fuction
|
1. Press the SET, UP, and DOWN buttons simultaneously for more than 3 seconds (Pump operation stops) 2. When the pump display is blinking, press the UP, DOWN button to change the pump number. 3. Press the SET KEY at the corresponding pump number and adjust the starting pressure value with the UP and DOWN buttons. 4. At this time, press the SET KEY in the same pump and adjust the starting pressure value with the UP and DOWN buttons. 5. Repeat 1-4 to change the number of pumps and adjust the pressure/stop pressure value to complete 6. After setting the start/stop pressure of all pumps, press and hold the SET button for 3 seconds to save and complete |
