★: The meaning of the indicator light:
◆ POWER ----- Power indicator, the light will always be on if the power is on.
◆ PUMP ------ Water pump running status indicator, when the pump is running, the light flashes (0.8S flashes one cycle ); when the pump stops normally, the light is on; Press the "STOP" button, the pump stops and the indicator light is off. .
◆ GROUP ----- Multiple Pump connection indicator, when the multiple pump connection is normal, the indicator light is on.
◆ ERROR ------- Water shortage indicator, when there is water shortage, the water shortage light flashes.
◆ SET ------ Setting indicator light, press the "Up" or "Down" button, or press the "up" and "down" buttons at the same time, the light will flash, if you don't press the button for 8 seconds, the light will automatically go out.
★ Parameters setting for inverter
★: Parameter settings function:
Press the <Up> and <Down> buttons simultaneously for 3 seconds to enter the parameter settings mode.
Press the <Run> button to confirm, save and change parameters:
◆ P001: check the current output frequency value.
◆ P002:check the current output current value.
◆ P003: check the current input voltage value.
◆ P004: check the current temperature.
◆ P010: Restore factory settings. Press the <Up> and <Down> buttons to switch between "0" and "1". The factory default value is displayed as "1", and it will be automatically changed to 0 once any parameter is changed. When the value is "1" and press the <Run> button, it will be restored to factory default setting.
◆ P011: Starting pressure parameter setting. Adjustment range: 0.1 -2 bar, the factory default is
0.3bar. You can set the automatic starting pressure value when the inverter is automatically turned off.
◆ P012: Pressure parameter setting for water shortage. The default setting is 0.1 bar, the water
shortage function is disabled and there is no water shortage protection when it's set to 0 bar.
◆ P013: Water shortage time parameter setting. Adjustment range: 0~60S, the default is 30S, It will automatically restart the pump for a specified time after water shortage protection: 10 seconds, 1 minute, 5 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours, 4 hours, and cycle of 4 hours until the pressure returns to normal.
◆ P014: Carrier frequency parameter setting. Optional: "L" and "H".
"L" is 6K for 2.2KW and 8K when it's less than 2.2KW; "H" is 8K for 2.2KW and 16K when it’s less than 2.2KW
◆ P015: Acceleration and deceleration time setting range: 20 to 50 hundred milliseconds (2 to 5
seconds), the default is 2 seconds. Adjusting this parameter can improve the problem of pressure rise too fast or too slow.
◆ P016: Permissible pressure error fluctuation value. Setting range: 0 to 1 bar, the default is 0.1 bar. Adjusting this parameter can effectively improve the pressure fluctuation during constant pressure operation. Increase or decrease 0.05 bar every button.
For problem of failing to be turned off because of wide range and pipe network dripping. This parameter setting can be used in conjunction with P011 to ensure there is no pressure fluctuation while working, and turn off the system effectively when it's under non-use conditions.
◆ P017: minimum frequency of shutdown, minimum 20HZ, maximum 40HZ, (default: 24HZ)
◆ P018: No shutdown is allowed, "1" is not shutdown, "0" is shutdown, and the default is "0".
◆ P019: Range selection (1.0--1.6--2.5Mbar) settings, the default is 1.0. If the setting pressure is 1.0Mbar, the pressure range is 0.5----9bar; if it's 1.6Mbar, the pressure range is 0.5--- 15bar; if it's 2.5Mbar , the pressure range is 0.5--- 24bar ;)
◆ P020: over-temperature setting (60--90- H), the default is 85 degrees
◆ P021: setting direction, 0 is forward rotation, 1 is reverse rotation, the default is 0.
◆ P022: local address (online), minimum 1, maximum 6, the default is 1. (1 Host , and 5 slave machines maximum ).
◆ P023: Round-robin time (online), minimum 0, maximum 72 hours, the default is 48 hours. (rotational working time, for example 48 hours after the host worked, it will then go to another slave machine that works for 48 hours, then goes to other slaves for 48 hours and working in a loop.)
◆ P024: The maximum number of devices that can run at the same time (online), minimum 1, maximum 6, the default 6. (Number of machines that are allowed to work at the same time while online. For example, when the setting is 1, only 1 host is working; if the setting is 2, when the pressure does not reach the setting pressure, 2 sets can work at the same time, and so on.)
