1 What is the function of each probe (water level control wire)

A (Red Wire): It is the upper limit water level control point of the upper pool (reservoir). When the water level rises to A point, the water surface contacts the probe A, and the water level controller automatically turns off the water pump and stops water injection.
B (Blue Wire): It is the lower limit water level control point of the upper pool (reservoir). When the water level drops below B point, the water surface is out of contact with the probe B, and the water level controller automatically turns on the water pump to start water injection.
C (Black Wire): It is the ground wire of the pool (reservoir). It needs to be placed at the lowest point of the pool in contact with the bottom of the pool.
D (Green Wire): It is the lower limit water level control point of the lower pool (drainage pool). The water level drops below D point, the water surface is out of contact with the probe D, and the water level controller automatically shuts off the water pump and stops draining.
E (Yellow Wire): It is the upper limit water level control point of the lower pool (drainage pool). The water level rises to E point, and the water surface touches the probe E, and the water level controller automatically starts the water pump and starts draining.

2 How to wire the probe

2.1 If you control the water level of the upper pool separately, you can connect as shown in Figure 8.1, that is, A is connected to the upper limit of the water level, B is connected to the lower limit of the water level, C is connected to the bottom of the pool, and D and E are connected to C.
2.2 If you control the water level of the lower pool separately, you can connect as shown in Figure 8.2, that is, A and B are not connected, C is connected to the bottom of the pool, D is connected to the lower limit of the water level, and E is connected to the upper limit of the water level.
2.3 If you control the water level of the lower pool separately and also need the water shortage protection function, it can be connected as shown in Figure 8.3, that is, A and B are not connected, C and D are connected to the lower limit of the water level, and E is connected to C.
2.4 If you need to control the upper and lower pools together, you can connect as shown in Figure 8.4, that is, A is connected to the upper limit of the water level of the upper pool, B is connected to the lower limit of the water level of the upper pool, C is connected to the bottom of the upper and lower pools, and D is connected to the lower limit of the water level of the lower pool, and E is connected to the upper limit of the water level of the lower pool (if the lower pool does not need to be drained, it is no need to connect E).

1. If it doesn't work after power on
1.1 Check if the red power indicator light is on. If it does not light up, please check whether the wiring of the input and output terminals are in good contact.
1.2 Check whether the "manual/auto" switch on the right side of the product is in the "off" position. If so, please adjust it back to the "auto" position, and the water level controller will automatically enter the working state.
2. If the water level line exceeds or falls below the water level control point, the water pump does not automatically close or open, please turn on/off the water pump manually through the "manual/auto" switch and check
2.1 Whether the position of the probe is deviated, if the installation position is too high (too low), the water surface cannot touch (detach) the probe normally.
2.2 Whether the cable of the probe is correctly connected to the corresponding terminal of the water level controller, and whether there is poor contact or short circuit.
2.3 Whether the probe is corroded or falling off.
2.4 Whether the probe C (ground) has been placed in the lowest position of the pool.

Attentions

---

1 In order to ensure the normal operation of the water level controller, after installing the water level controller, please check the wiring of the input end and the output end, and whether the connecting wire of the probe is in reliable contact. The actual working environment can be simulated by moving the probe up and down (to contact or leave the water surface) to detect whether the water level controller is installed correctly and functions normally.
2 It is recommended to fix each probe on the inner wall of the pool to prevent the water level controller from malfunctioning due to the shifting of the probe position. If the material of the inner wall of the pool is metal, all probes except probe C (ground) should not be connected to the inner wall to avoid short circuit and cause the water level controller to not work normally.
3 After connecting the cable according to the operating instructions, please check whether the water pump can be turned on or off manually through the "manual/auto" switch on the right side of the controller (DF-96D does not have this switch). After checking, please adjust it back to the "auto" position, and the water level controller will enter the automatic working mode.
4 If you need to turn on/off the water pump temporarily, please control it through the "manual/auto" switch on the right side of the water level controller (DF-96D does not have this switch).
5 In order to avoid malfunction, please do not install the water level controller in humid, corrosive and high metal content gas environment.
6 It is recommended to use the probe produced by our company.

When you think there is a fault (FAQs)

---

Note: When the product fails, please disconnect the power first, and then check the equipment!
1 Check the week
If the bell controller does not turn on the electric bell at the set time, it may be that the "WEEK" is not adjusted correctly, please check or reset it according to the method introduced in "Timing Setting".
2 Check the time groups
If the first point is confirmed to be correct, but the electric bell still cannot be turned on in the right time, the reason will be that the extra time group has not been cancelled. Please refer to the method introduced in "Timing Setting" to delete it. PS: Only when the display shows "--: --", it means the time group is deleted successful; if it displays "00:00", it means 0 o'clock (24 o'clock), not the deleting success.
3 Check the switching mode
If the above two points are confirmed to be correct, but the bell controller still does not work normally, it may be that the bell controller is working in "Manual Mode". You can first adjust the "AUTO/MANU" key to set the bell controller to the right working state of the electric bell (ON or OFF), then switch to the "Automatic Mode".
4 Check the fuse
If the above three points are correct and the bell controller still cannot work normally, please open the rear seat insurance cover (terminal cover) and check whether the fuse has been blown. If it is blown, please replace with a new 0.1A~0.3A fuse.
5 Check the power supply
If the Work LED (or Output LED) is on when the bell controller is working, but the electric bell cannot be turned on normally, please check whether the voltage of the power supply is too low. If the bell controller is burned out, please check whether the power supply voltage exceeds the rated voltage of the product and whether the power cable is connected incorrectly.
6 Please replace the battery
If the LCD screen does not display or the display is not clear, replace the battery with the same specification. (Only for bell controller with replaceable batteries)

DH48S Series Digital Time Relay - Product Information | HUIMU Instruments

 

DH48S Series

Digital Time Relay

Parameters

---

  DH48S series digital time relay acts as a delay element in the control circuit, which can turn on or off the circuit at a predetermined time. DH48S series digital time relay consists of large-scale integrated circuit, has excellent EFT and ESD anti-interference ability, and its delay accuracy can reach 0.01 second. DH48S series digital time relay is a device with time-delay after power-on feature, that is, it starts timing after power-on, and after timing is over, it starts to turn on/off the load. Therefore, the time relay must be set before power-on, and the setting after power-on is invalid.

Instructions For Use (How to set)

---

Step one. Wiring

Connect the load, switch and power supply to the corresponding terminals of the time relay.

Step two. Time setting

Set the delay time before powering on. (1) 0.01secs~99.99secs (2) 1sec~99mins99secs (3) 1 min~99hours99mins

Step three. Power up

After setting the time relay, turn on the power, then the time relay will display and start timing. Once it reaches the set time, the time delay contact starts to act to realize the delay control of the load. The interval between repeated activations of the time relay should be ≥0.5 seconds. Note: The delay time should be set before power on, any setting after power on is invalid.
