7 steps to solve the failure of time control switch (Timer Switch)

Note: When the product fails, please disconnect the power first, and then check the equipment!

1 Check the week:

If the timer switch does not turn on or turn off the load 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 load still cannot be switched correctly on 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 timer switch still does not work normally, it may be that the timer switch is working in "Manual Mode". You can first adjust the "AUTO/MANU" key to set the timer switch to the right working state of the load (ON or OFF), then switch to the "Automatic Mode".

4 Check the fuse:

If the above three points are correct and the timer switch 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 timer switch is working, but the load cannot be switched normally, please check whether the voltage of the power supply is too low. If the timer switch 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 timer switch with replaceable batteries)

7 Please contact us or local distributor:

If the fault cannot be eliminated by the above methods, please contact us or the distributor (dealer) in your local area.

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.

2.2 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).

DF series probe installation

When you think there is a fault (FAQs)

---

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.
