5.1 Battery Installation (for 220V models)

The 110V version of this timer switch has an inbuilt battery for data storage. For the 220V version, an external AA battery (not included) is required to retain settings during power outages. Locate the battery compartment, insert one AA battery, ensuring correct polarity.

5.2 പ്രാരംഭ പവർ-അപ്പ്

Once wired correctly and power is supplied, the LCD display will illuminate. If the display is blank, check the power connection and battery (if applicable).

6. വയറിംഗ് നിർദ്ദേശങ്ങൾ

Proper wiring is crucial for the safe and correct operation of the timer switch. Refer to the diagrams and descriptions below. If you are unsure, consult a qualified electrician.

ചിത്രം 6.1: View of the KG316T timer switch terminals for wiring connections.

6.1 Direct Control Wiring (Single-Phase, Low Power)

This wiring method is suitable for single-phase powered electrical appliances with lower power consumption that falls within the switch's direct load capacity (10A resistive/inductive).

6.2 Single-Phase Expansion Wiring

For single-phase powered electrical appliances with higher power consumption than the direct load capacity of this switch, you will need an external alternating current contactor. The timer switch will control the coil voltage of this external contactor, which in turn handles the higher load.

6.3 Three-Phase Wiring (AC220V Control Coil)

For three-phase electrical appliances, with an AC220V control coil voltage, you will need an external three-phase AC contactor. The timer switch will activate or deactivate the coil of this contactor to control the three-phase load.

6.4 Three-Phase Wiring (AC380V Control Coil)

Similarly, for three-phase electrical appliances with an AC380V control coil voltage, you will need an external three-phase AC contactor. The timer switch will manage the operation of this contactor to control the three-phase power.

7. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

7.1 Setting Clock (Present Time)

1. Press and hold the "CLOCK" button.
2. While holding "CLOCK", press "WEEK" to set the current day of the week.
3. While holding "CLOCK", press "HOUR" to set the current hour.
4. While holding "CLOCK", press "MINUTE" to set the current minute.

7.2 Setting Programs (ON/OFF Times)

The timer supports up to 10 ON and 10 OFF settings.

1. Set "1 on": Press the "TIMER" button. The LCD will display "1 on" at the bottom left. Then press "HOUR" and "MINUTE" buttons to set the desired ON time for the first program.
2. Set "1 off": Continue to press the "TIMER" button. The LCD will display "1 off" at the bottom left. Then press "HOUR" and "MINUTE" buttons to set the desired OFF time for the first program.
3. Set Additional Programs: Continue to press the "TIMER" button. The LCD will successively display "2 on", "2 off", "3 on", "3 off" ... up to "10 on", "10 off". Repeat the process of setting HOUR and MINUTE for each desired ON/OFF program.
4. Clearing Unused Programs: If you only need a few programs (e.g., "1 on", "1 off") and wish to clear the remaining ones, press the "TIMER" button until the desired program number is displayed (e.g., "2 on"). Then press the "RESET/RECALL" button. This will set the time for that program to "--:--" instead of "00:00" (shown on the LCD), effectively disabling it.
5. സേവിംഗ് ക്രമീകരണങ്ങൾ: After completing all program settings, press the "CLOCK" button. The LCD will display the present time. If no button is pressed for 30 seconds, it will automatically display the present time and save the settings.

7.3 ഇൻഡിക്കേറ്റർ ലൈറ്റുകൾ മനസ്സിലാക്കൽ

• When connected to a circuit, the red light (POWER) indicates if the circuit is powered.
• ദി green light (WORK) indicates if the switch is closed (i.e., the output is active and power is being supplied to the connected appliance).

7.4 Using the AUTO/MANU Button

Press the "AUTO/MANU" button to cycle through different operating modes:

• ഓൺ: The switch is manually forced ON, overriding programmed settings.
• സ്വയമേവ: The switch operates according to the programmed ON/OFF times.
• ഓഫാണ്: The switch is manually forced OFF, overriding programmed settings.

To return to automatic operation, press the "AUTO/MANU" button until the LCD displays "AUTO".

7.5 Setting Days of the Week for Programs

After setting an ON/OFF program, you can specify which day or days of the week it should be active:

• Press the "TIMER" button to navigate to the desired program (e.g., "1 on").
• Then press the "WEEK" button repeatedly to cycle through various day combinations:
  • Mon, Tue, Wed, Thu, Fri, Sat, Sun (All days)
  • മോൺ
  • ചൊവ്വ
  • ... (Individual days)
  • Mon, Tue, Wed, Thu, Fri (Weekdays)
  • Sat, Sun (Weekends)
  • Mon, Wed, Fri
  • Tue, Thu, Sat
  • Mon, Tue, Wed
  • Thu, Fri, Sat
  • And other combinations.
• Select the desired day combination for that specific program.
