1. Product Overview The detection components (oil and water probe, float switch, thermal switch and >) installed inside the pump provide comprehensive protection for the submersible pump. The main principle is to use the detection element in the pump as a sampling signal. The sampling signal is filtered and amplified by the controller, input to the microcontroller system in the controller, and compared with the parameters set in the program. Instructions are issued based on the operation results to control The actuator and the panel light indicate the operating status.
2. Working conditions
The controller works normally under the following conditions:
, the altitude of the installation site is > meters.
, ambient temperature>+>>℃
.
There is no explosive medium in the environment, no moist gas and dust that can corrode metal and damage insulation, and the monthly average maximum humidity is > (℃).
, vertical installation slope>.
The working power supply of the controller is >C
3. Operation panel description
The controller panel is equipped with four operation buttons, four signal lights and a four-digit digital tube display
, four operation buttons: menu (>) r key, setting () r key, up (△) r key, down (▽) r key
, four > indicator lights
R oil chamber The oil and water probe (lower probe) alarms or >alarms temperature, when there is a fault (flashes)
RThe upper end cover probe (upper probe) of the motor alarms or >the shutdown temperature, when there is a fault (always on)
Motor winding thermal sensitivity Switch (overheating), when there is a fault> (always on)
Motor wiring cavity leaks (float or oil-water probe), when there is a fault (always on)
, fault sound alarm
Contains a The alarm buzzer does not buzz in normal status and alarm, but buzzes in case of fault. The buzzing duration is determined by the > value,
: turn off the buzzer> ~ buzzer duration (seconds): keeps buzzing Ming.
During the alarm buzzing, press the Set r key to eliminate the alarm buzzing.
>Four-digit digital tube display:
>When the > model is used, it will display . ~ . r. It will alternately display after a few seconds if the button is not pressed.
>When using Model B, . ~ . r is displayed. It will alternately display after a few seconds if the button is not pressed.
Press the up r or down r key to enter View > Channel input resistance and channel temperature values
The display is as follows
.:
． : Indicates > R input resistance: Indicates resistance value unit.
． : Indicates > R input resistance: Indicates resistance value unit.
． : Indicates > Input resistance: Indicates resistance value unit.
． : Indicates > Input resistance: Indicates resistance value unit.
． : Indicates > Measuring temperature: Indicates the temperature value in °C.
． : Indicates > Measuring temperature: Indicates the temperature value in °C.
If > is displayed, the resistance value is greater than or the temperature is greater than >>℃
If > is displayed, the resistance value is less than or the temperature is less than >>℃
If > is displayed, the temperature value sensor wiring is disconnected, Or wiring error.
4. Brief description of controller function application
, Oil and water probe in the oil chamber (lower probe > R), the corresponding water pump signal lines are No. line and No. line
When the oil and water probe in the oil chamber detects the resistance value >When (lower probe R) is less than the set value (default is), the internal relay of the controller is closed, and the corresponding controller panel R flashes (times/). When the resistance value R of the oil and water probe in the oil chamber is greater than the set resistance value, the controller The internal relay automatically releases, corresponding to the automatic recovery of the controller panel R
, the motor upper end cover probe> (upper probe R), the corresponding water pump signal line is the No. line and the No. line
When the motor upper end cover probe detects the resistance value >When (upper probe R) is less than the set value (default is), the relay inside the controller is closed, and the corresponding controller panel R is always on. When the probe on the upper end cover of the motor detects the resistance value R, it returns to the normal resistance value (greater than the set resistance). value), the internal relay of the controller and the controller panel R do not automatically recover, and must be reset by pressing the controller panel setting r key.
, motor winding thermal switch> (winding overheated), the corresponding water pump signal lines are No. and No. wires
According to the nature of the motor winding thermal switch (normally open or normally closed), you can use the menu The setting of >B in must match it. When B is set to r (default), the motor winding thermal switch is normally open. When B is set to r, the motor winding thermal switch is normally closed. According to the B setting in the menu, when the controller detects that the motor winding thermal switch changes from normally open to normally closed or from normally closed to normally open: the internal relay of the controller is closed, and the corresponding controller panel is always on. When the control When the controller detects that the motor winding thermal switch returns to normal, the relays inside the controller and the controller panel do not automatically recover and must be reset by pressing the r key on the controller panel.
, the detection component in the motor wiring cavity (float switch or oil and water probe), the corresponding water pump signal line is the number line and the number line
According to the nature of the detection component in the motor wiring cavity (float switch or oil and water probe) , which can be determined by setting >C in the menu to match it. When C is set to r (default), the motor wiring detection component is a float switch. When C is set to r, the motor wiring detection component is an oil-water probe. According to the C setting in the menu, when the controller detects that the float switch in the motor wiring cavity changes from normally open to normally closed or the resistance value is less than the set value (default is), the internal relay of the controller is activated, and the corresponding controller panel is always on. When the controller detects that the float switch or oil-water probe in the motor wiring cavity returns to normal, the relays inside the controller and the controller panel do not automatically recover and must be reset by pressing the r key set on the controller panel.
, two-channel> temperature detection setting (B model),
The controller panel displays the temperature values of the two channels alternately in a cycle. If there is no connection> or abnormality, the controller panel displays r
Control When the controller detects that the temperature of any channel is greater than its set alarm temperature value, the internal relay of the controller is closed, and the corresponding controller panel R flashes (times/).
When the controller detects that the temperature of any channel is greater than its set shutdown temperature value, the internal relay of the controller is closed, and the corresponding controller panel R is always on. When the controller detects that the temperature has recovered (less than the shutdown temperature value) , the internal relay of the controller and the controller panel R do not automatically recover, and must be reset by pressing the controller panel setting r key.
