WBS Solar Pump Monitor For Resin-Encapsulted Motor DC Pump
Main function
(1) Three operating modes: automatic mode, AC mode, DC mode.
In the automatic mode, the power supply of the DC terminal is connected first, and the AC is only connected when the DC voltage is lower than the starting voltage (150V) or the operating power is low. If the time switch function is turned on, only the AC power supply is turned on during the night time period, and the above-mentioned DC power supply priority strategy is adopted only during the sunshine time period.
In AC mode, only the AC power supply is connected When the AC is under-voltage then stops running.
In DC mode, only the power supply of the DC terminal is connected, and the DC is under-voltage or lower than the starting voltage (150V), then the operation is stopped.
(2) Low power or low flow judgment
When the water outlet is connected to the flowmeter to judge whether the water is discharged, the SW2 should be turned to the ON position, and when it is not connected, the SW2 should be turned to the OFF position. When SW2=ON, only low flow is judged; When SW2=OFF, only low power is judged. Both will not be judged at the same time.
(3) AC and DC power supply timing switching function
Reasonably set parameters P3.1 and P3.2, which can be switched to solar power supply for operation after sufficient sunshine every morning; In the afternoon, after the sun disappears,
switch to the standby power supply (AC or battery) for operation.
If P3.1=P3.2 is set, the timing switching function is invalid (the factory default is invalid).
(4) Time switch function
Timing start-up: P3.3 startup time needs to be set, and P3.4 shutdown time needs to be set for scheduled shutdown.
When P3.3=P3.4 is set, the timing startup/shutdown function is invalid (the factory default is invalid).
(5) Auto start generator function
