4. ઇન્સ્ટોલેશન અને વાયરિંગ
The TM919B timer switch is designed for DIN rail mounting, making it suitable for integration into electrical distribution boards. Ensure all power is disconnected before attempting installation.
વાયરિંગ ડાયાગ્રામ:
Figure 4: Wiring diagram for the TM919B. Terminals 1 and 2 are for power input (L and N). Terminals 3, 4, and 5 are for the output, typically used for NO (Normally Open) and NC (Normally Closed) connections to control the load.
- પાવર ઇનપુટ: Connect the live (L) and neutral (N) wires to terminals 1 and 2 respectively. Ensure the voltage matches the timer's specification (110V for this model).
- લોડ કનેક્શન: The timer has a single changeover switch.
- Terminal 3: Normally Closed (NC) contact.
- Terminal 4: Common (COM) contact.
- Terminal 5: Normally Open (NO) contact.
- Connect your load (e.g., lamp, motor) between the common terminal (4) and either the NO (5) or NC (3) terminal, depending on whether you want the load to be ON or OFF when the timer is in its default state.
- Securely fasten all wires to prevent loose connections.
- Once wiring is complete, restore power and proceed with programming.
5. Operating Instructions and Programming
The TM919B timer allows for up to 16 ON/OFF programs. Follow these steps to set the current time and program the timer.
બટન કાર્યો:
- P (Program): પ્રોગ્રામિંગ મોડમાં પ્રવેશ કરે છે.
- D+ (Day): Adjusts the day of the week.
- H+ (Hour): Adjusts the hour.
- M+ (Minute): Adjusts the minute.
- ફરીથી સેટ કરો: Resets all settings to factory defaults. Use a pointed object to press.
- મેન્યુઅલ: ચાલુ, ઓટો અને બંધ મોડ વચ્ચે ટૉગલ કરે છે.
વર્તમાન સમય સેટ કરી રહ્યું છે:
- દબાવો D+ અઠવાડિયાનો વર્તમાન દિવસ સેટ કરવા માટેનું બટન.
- દબાવો H+ વર્તમાન કલાક સેટ કરવા માટે બટન.
- દબાવો M+ વર્તમાન મિનિટ સેટ કરવા માટે બટન.
- The time will automatically save after a few seconds of inactivity.
પ્રોગ્રામિંગ ચાલુ/બંધ સમય (16 પ્રોગ્રામ સુધી):
- દબાવો P બટન એકવાર દબાવો. ડિસ્પ્લે "1 ચાલુ" બતાવશે. આ પ્રથમ ચાલુ સમય સેટ કરવા માટે છે.
- દબાવો H+ અને M+ to set the desired hour and minute for the first ON event.
- દબાવો D+ to select the days of the week for this program. Options include: every day, specific days (e.g., MO-FR, MO-SA, SA-SU), or individual days. If you want the same setting every day, you do not need to press D+.
- દબાવો P button again. The display will show "1 OFF". This is for setting the first OFF time.
- દબાવો H+ અને M+ to set the desired hour and minute for the first OFF event.
- દબાવો D+ again if you need to specify different days for the OFF event, or leave it if it matches the ON event's days.
- Repeat steps 1-6 for programs 2 through 16 (e.g., "2 ON", "2 OFF", etc.).
- બધા ઇચ્છિત પ્રોગ્રામ્સ સેટ કર્યા પછી, દબાવો મેન્યુઅલ button repeatedly until "AUTO" is displayed. This ensures the timer operates according to your programmed schedule.
મેન્યુઅલ નિયંત્રણ:
દબાવો મેન્યુઅલ ઓપરેટિંગ મોડ્સમાંથી પસાર થવા માટે બટન:
- ચાલુ: The output is continuously ON, overriding programmed settings.
- બંધ: The output is continuously OFF, overriding programmed settings.
- UTટો: The timer operates according to the programmed ON/OFF schedules. Ensure the timer is in AUTO mode for automatic operation.
6. જાળવણી
The TM919B timer switch requires minimal maintenance. Keep the device clean and free from dust. Do not expose it to excessive moisture or extreme temperatures. If the display becomes dim or unresponsive, check the power supply. The internal battery provides backup for settings during power outages for up to 60 days.
7. મુશ્કેલીનિવારણ
| સમસ્યા | સંભવિત કારણ | ઉકેલ |
|---|---|---|
| Timer not turning ON/OFF at programmed times. | Not in AUTO mode; incorrect programming; power issue. | Press MANUAL until "AUTO" is displayed. Review programming steps carefully. Check power supply to the timer. |
| ડિસ્પ્લે ખાલી અથવા ઝાંખું છે. | No power supply; internal battery low (unlikely for display). | Check power connections. Ensure the timer is receiving power. |
| સમય કે કાર્યક્રમો સેટ કરી શકાતા નથી. | બટનો પ્રતિભાવહીન; યુનિટ સ્થિર. | Press the RESET button using a pointed object. This will clear all settings, so you will need to reprogram. |
| Load not switching. | Incorrect wiring; faulty load; timer output issue. | Verify wiring according to the diagram. Test the load independently. If issues persist, contact support. |
