Basic function introduction Automatic water level control: the water level is lower than the low level sensor probe, the water pump is automatically started, the water level rises to the high level, and the water pump is automatically turned off. . 4 / 14 (Automatic water supply) Automatic water level control: the water level rises to a high level, the water pump is automatically started, and the water level is lower than the low level sensor probe, and the water pump is automatically turned off. (Automatic drainage) Manual automatic switching: The controller enters the automatic working mode by default when it is turned on. Press the K1 key to switch the working mode. The red light is on for automatic mode, and the red light is off for manual mode. Water inlet pipe abnormal alarm: When the controller starts to pump water automatically, and the water inlet pipe probe cannot detect water within a certain period of time (within 10 to 30 seconds), the load output relay is disconnected to stop pumping, and the alarm output relay is closed. Abnormal water overflow alarm: the controller starts to pump water automatically, and when the water surface rises to the position of the overflow alarm probe, the load output relay is disconnected to stop pumping, and the alarm output relay is closed. Abnormal low probe alarm: the controller starts to pump water automatically. If the low probe fails or falls off, and the water surface rises to the high probe position, the load output relay is disconnected to stop pumping, and the alarm output relay is closed. Oview high and low level controller and Y26-V liquid level detection head realize the function of liquid level high and low control: when the container liquid level is too low, the low liquid level alarm signal sent by the low liquid level sensor is triggered to trigger the C362 controller to close the relay to start the water pump Add the liquid level, when the liquid level reaches a certain height, the high liquid level sensor sends out a signal to trigger the C362 controller to disconnect the relay and automatically stop the water pump to work in a cycle. Thereby, the function of automatic control of the container liquid level is realized, and the container liquid level is kept stable. Product Features AC180V~250V power supply Relay dry node output, suitable for various load control The control is diversified, and the pump can be controlled in manual or automatic mode The installation is simple and convenient, it can be installed with screws or electric box tracks Terminal description Parameter Input voltage: AC180V-250V，50/60Hz Working current: Working current ≤110 mA, static current consumption: ≤20mA Load power: Resistive load below 1.6KW (overload or three-phase load needs to be installed with AC contactor) Inductive load below 1KW (overload or three-phase load needs to be installed with AC contactor) Inductive loads refer to loads with inductive coils, such as motors, electromagnets, solenoid valves and so on.

Sensor probe installation: different types of sensor probes have different installation methods, please refer to the relevant chapters of the specifications corresponding to the sensor model you are using. I won't repeat them here. 1 Probe wiring diagram The following figure uses the high and low water level controller + 1 Y26 non-contact liquid level sensor to realize automatic water level control Correspondence diagram of signal input and relay output Input signal Low bit is 0, high bit is 0; Load output: Normally open end (NO) is closed, normally closed end (NC) is open Input signal the low bit is 1, the high bit is 0 (The water level rises); Load output: Normally open end (NO) is closed, normally closed end (NC) is open Input signal the low bit is 1, the high bit is 1; Load output: Normally open (NO) open, normally closed (NC) closed Input signal the low bit is 1, the high bit is 0 (Water level drops); Load output: Normally open (NO) open, normally closed (NC) closed Alarm signal status: the low bit is 0, high bit is 0; Alarm Output: Normally open end (NO) is closed, normally closed end (NC) is open Alarm signal status: High overflow is 1; Alarm Output: Normally open end (NO) is closed, normally closed end (NC) is open Alarm status, load output: normally open open, normally closed closed (Relay disconnected state, load disconnected to enter protection) Note: 0 means that the probe cannot detect water and outputs a low-level 0V voltage, 1 means that the probe detects that there is water and outputs a high-level 12V voltage. 2 Probe wiring diagram The following figure uses the high and low water level controller + 2 Y26-V non-contact liquid level sensors to achieve automatic water level control. 3 Probe wiring diagram The following figure uses the high and low water level controller + 3 Y26-V non-contact liquid level sensors to realize functions such as automatic water level control and water pump idling protection.
