Disposal of Electrical WasteAll electrical waste should bedisposed of in compliance withcurrent WEEE regulations.CautionThe products must be installed by qualified electricians. All andany electrical connections of the time relay shall comply withthe appropriate safety standards.NOTE: the use case is for reference only to understand the working principle of the relay. The actual application should be wired according to the actual needs.CASE1: The working mode is set to 07 and accessed through the sensor (PNP). When the sensor senses the signal, the relay acts (15-18 is closed) and the ventilation fan works. When the sensor loses the signal, the relay disconnects after a delay t (15-18 is disconnected) and the ventilation fan stops working.Sensor（PNP）BrownBlackFanCASE 2: The working mode is set to 03, the ventilation fan is turned on for 10 hours and turned off for 1 hour, and the ventilation fan is cycled on and off.AC220V~~CASE 3: When the working mode is set to 02, the time relay is powered on (15-18 is closed), the contactor is closed, the water pump starts to work, the delay t reaches, the relay is disconnected (15-18 is disconnected), the contactor is disconnected, and the water pump stops working.PUMPLEDCASE 4: The working mode is set to 08, press the trigger button, the time relay acts (15-18 is closed), turn on the LED, delays t, the relay is disconnected (15-18 is disconnected), and the LED is closed.AC220V~~Trigger buttonFanOutput indication(red)Button (UP)MDR15161815161825262828

When the relay Un is in the power on state, when the S control terminal is connected, the relay will be closed immediately. When the Scontrol terminal is disconnected, the delay will start. After the delay t, the output contact will be disconnected. During the delay process, the S control terminal will be connected and disconnected again, and the delay t will be cleared and delayed again。When the relay Un is in the energized state, when the S control terminal is connected, the relay is closed, and the relay starts to delay. After the delay t, the output contact is disconnected. During the delay t, the S control terminal is connected again, and the delay t remains unchanged and continues to delay.When the relay Un is in the energized state, when the S control terminal is disconnected, the relay is closed, and the relay starts to delay. After the delay t, the output contact is disconnected. During the delay t, the S control terminal is switched on and off again, and the delay t remains unchanged and continues to delay.t1t1Unt1t2When relay Un is powered on, the relay starts to delay. After delay t1, the output contact is closed. At the same time, after delay t2, the relay is disconnected and maintained. After relay Un is powered off, the output contact is disconnected.

After the delay t, the output contact is closed. When the S control terminal is disconnected, the output contact is disconnected.When relay Un is powered on, the relay starts to delay, and the output contact is closed after delay t. After the relay Un is de energized, the output contact is disconnected and the S control signal is invalid in this function mode.When relay Un is powered on, the relay output contact will be closed immediately and start delay. After delay t, the output contact will be disconnected. If the delay time t does not arrive and relay Un is powered off, the output contact will be disconnected, and the S control signal is invalid in this function mode.When relay Un is powered on, the relay starts to delay. After delay t1, the output contact is closed. At the same time, after delay t2, the relay output contact is disconnected. In this way, the cycle delay is delayed until relay Unis powered off, and the S control signal is invalid in this function mode.When the relay Un is powered on, the relay is closed and begins to delay. After the delay t2, the output contact is disconnected. At the same time, after the delay time t1, the relay output contact is closed.
