KG316T (Multiple Output)

1 Direct control method (as shown in Figure 1)
Applicable objects: Loads with single-phase power supply, and the power consumption does not exceed the rated switching capacity of the timer switch.

2 Single-phase expansion method (as shown in Figure 2)
Applicable objects: load with single-phase power supply, but the power consumption exceeds the rated switching capacity of the timer switch. This method should be adopted for inductive loads.
If this wiring method is adopted, the output terminal of the digital timer switch needs to be connected to a single phase AC contactor whose switching capacity should larger than the power consumption of the load to expanse the switching capacity of the timer switch. For example, Figure 2.1 shows how to expand the switching capacity of OUT2 of KG316T-2a, and Figure 2.2 shows how to expand the switching capacity of OUT3 of KG316T-3a.

*Note: Each load of this product and the power supply share a neutral line. Please make sure not to connect it wrongly when wiring.

2 Operating instructions

Step 1. Timing setting (on)

Press the " TIMER " button to enter the "Editing Mode". At this time, the "1^ON" symbol will appear at the bottom left of the LCD screen (that is, the first time to turn on the load, as shown in Figure 3), and then press the "WEEK" to select Working Mode, and then press the "HOUR" and "MINUTE" keys to input the required switching on time.

Step 2. Timing setting (off)

Press the " TIMER " button again, the "1_OFF" symbol will appear at the bottom left of the LCD screen (that is, the first time to turn off the load, as shown in Figure 4), and then press the "WEEK" to select Working Mode, and then press the "HOUR" and "MINUTE" keys to input the required switching off time. At this time, the first group of timing setting has been completed.

Timing Setting1

Step 3. Timing setting (output combination)

For multiple-output timer switches, the output combination can be configured through the "AUTO/MANU" key when in the "Editing Mode" (as shown in Figure 7). KG316T-2a has three output combinations (OUT1, OUT2, OUT1-OUT2); KG316T-3a has six output combinations (OUT1, OUT2, OUT3, OUT1-OUT2, OUT1-OUT3, OUT1-OUT2-OUT3, OUT2-OUT3). Take KG316T-3a as an example. If you want LOAD 2 to turn on at 10 o'clock AM, you can set it according to Figure 8; if you want LOAD1 and LOAD 3 to turn off at 6 o'clock PM, you can set it according to Figure 9.

Timing Setting2

Step 4. Timing setting (number of groups)

After completing the first group of timing setting, press the "TIMER" button again, the LCD display will show the "2^ON" symbol, and you can set the second set of time setting. According to actual needs, you can repeat steps 1 to 3 to set many groups (the maximum programmable group number depends on the product's built-in chip). If you want to exit the "Editing Mode", you can press the "CLOCK" key to exit it.

Step 5. RESET/RECALL

After setting a group of time, for example, turn on the LOAD1 at 18:30 every day (Figure 5), and turn off the LOAD1 at 23:20 every day (Figure 6). If you want to cancel this group, you can press the "RESET/RECALL" button to delete this group of time settings. At this time, the group of time will be reset to the initial state, that is, "--: --" (Figure 3 and Figure 4). Under certain conditions (without any key operation or switching to other interfaces within 20 seconds after cancel operation), just press the "RESET/RECALL" button again to restore this group of time settings.

Step 6. AUTO/MANU

The timer switch has two switching modes: automatic and manual. In the automatic mode, the timer switch will be set according to the timing of steps 1 to 4, and the load will be automatically turned on or off at the corresponding time without human intervention. In manual mode, the load must be turned on or off by manual adjustment.
The specific operations are as follows:
1) If you need to turn on the load manually, you can click the "AUTO/MANU" button to switch the "▼" symbol on the display to the "ON" position (Figure 10). At this time, the load will always be in the on state and cannot be turned off automatically.
2) If you need to turn off the load manually, you can click the "AUTO/MANU" button to switch the "▼" symbol on the display to the "OFF" position (Figure 11). At this time, the load will always be in the off state and cannot be turned on automatically.
3) If you need to switch the load automatically, you can click the "AUTO/MANU" button to switch the "▼" symbol on the display to the "AUTO" position (Figure 12). At this time, the working state of the load will be switching automatically according to the timing setting, without being interfered by humans.

Step 7. Lock and unlock

For the timer switch with button lock (or keyboard lock), you can quick press the "RESET/RECALL" key four times to lock or unlock all the buttons.
-How to lock the buttons?
In the unlocked state, quick press the "RESET/RECALL" button four times or without any operation within 30 seconds to lock all the buttons (Figure 13). At this time, there will be a "∂" symbol in the bottom left, and you cannot make any settings for the timer switch.
-How to unlock buttons?
In the locked state, quick press the "RESET/RECALL" button four times to unlock all the buttons (Figure 14), and you can make settings at this time.

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 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.
