For the 4CHPROR3 products, all the four channel switches are dry contact, it can be used for AC and DC Electric Motor.

Motor TypeMotor Wire4CHPROR3 Max Load
AC Electric Motor10A/2200W/Gang
DC Electric Motor10A/2200W/Gang

AC Electric Motor connected to 4CHPROR3 wiring guide:

DC Electric motor connected to 4CHPROR3 wiring guide:

Note:

1. Above diagrams did not show the power supply for the 4CHPROR3.

2. The AC motor wiring guide shows forward direction connects to CH1, reversal direction connects to CH2, you also can connect the forward/reversal direction to the channel that you like to use.

3. Device must be set in interlock mode while connecting with motor as above shown.

4. When the device is in interlock, the Timer function is not available.

5. when interlock is activated, all four channels are in interlock mode, it is impossible to set two channel with interlock while the other two channel with self-locking mode.

Please check the following problems by the LED indicator status:

The LED indicator flashes once on repeated means you fail to connect to the router.

1. Maybe you entered a wrong Wi-Fi SSID and password.

2. Maybe your router has a lower carrying capacity.

3. Maybe you place device in a space with a weak Wi-Fi signal.

4. Be sure that the MAC of the device is not in the black list of your MAC management.

The LED indicator flashes twice on repeated means you fail to connect to the server.

1. Make sure Internet connection is working.

2. Please contact your ISP and confirm our server address is not shielded:

cn-disp.coolkit.cc (China Mainland)

as-disp.coolkit.cc (in Asia except China)

eu-disp.coolkit.cc (in EU)

us-disp.coolkit.cc (in US)

If none of the above methods solved this problem, please submit your request via help&feedback on eWeLink APP.

Device pairing failed issue

1. Make sure device is in the pairing mode.

2. Make sure your Wi-Fi network runs on 2.4GHz band. Please try Compatible Pairing Mode (AP) or upgrade eWeLink APP to 4.0.0 version or higher if you use a dual-band router.

3. Make sure you entered a correct Wi-Fi SSID and password, no special characters contained.

4. The device shall get close to the router for a good transmission signal condition while pairing.
