૧. પરિચય અને ઉત્પાદન સમાપ્તview

This manual provides essential information for the proper installation, operation, and maintenance of the Buderus Safety High Limit Sensor, model 78194. This sensor is a critical safety component designed specifically for use with Buderus GB142 Series Boilers (GB142-24, GB142-30, GB142-45, GB142-60). Its primary function is to monitor the boiler's water temperature and prevent overheating by shutting down the burner if the temperature exceeds a safe limit, thereby protecting the boiler system and ensuring operational safety.

The image shows the Buderus Safety High Limit Sensor, model 78194, still sealed in its clear plastic packaging. The sensor consists of a black insulated wire leading to a white electrical connector on one end, and a metallic, threaded probe on the other end. A white label with 'SIKA' logo is visible on the black wire. The metallic probe appears to be made of copper, as indicated in the product specifications.

4. સેટઅપ અને ઇન્સ્ટોલેશન

The Buderus Safety High Limit Sensor is designed for direct replacement in compatible GB142 Series Boilers. Installation should only be performed by a qualified technician.

સ્થાપન પગલાં (સામાન્ય માર્ગદર્શન):

1. પાવર ડિસ્કનેક્શન: Turn off and disconnect all electrical power to the boiler at the main circuit breaker. Verify power is off using a voltage મીટર.
2. Boiler Cool-Down: Allow the boiler to cool down completely to a safe handling temperature.
3. System Depressurization: If the sensor is installed in a wet well or directly in the water path, ensure the boiler system is drained and depressurized according to the boiler's service manual.
4. જૂનું સેન્સર શોધો: Identify the existing high limit sensor on the boiler. Refer to the specific GB142 boiler manual for its exact location.
5. જૂનું સેન્સર દૂર કરો: Carefully disconnect the electrical wiring from the old sensor. Unscrew or unclip the old sensor from its mounting location. Be prepared for any residual water if the system was not fully drained.
6. નવું સેન્સર ઇન્સ્ટોલ કરો: Apply appropriate thread sealant (if applicable) to the new sensor's probe. Carefully screw or clip the new sensor into place, ensuring a secure fit. Do not overtighten.
7. વાયરિંગ કનેક્ટ કરો: Reconnect the electrical wiring to the new sensor, ensuring correct polarity and secure connections.
8. System Repressurization & Refill: If the system was drained, refill and repressurize it according to the boiler manufacturer's instructions. Check for leaks.
9. Power Restoration & Test: Restore electrical power to the boiler. Perform a functional test of the boiler and observe the high limit sensor's operation as per the boiler's service manual.

Always consult the specific Buderus GB142 Series Boiler installation and service manual for detailed, model-specific instructions and diagrams.

5. ઓપરેટિંગ સૂચનાઓ

The Buderus Safety High Limit Sensor operates automatically as a safety device within the boiler control system. It does not require manual operation.

• કાર્ય: The sensor continuously monitors the boiler's water temperature. If the temperature rises above a pre-set safe limit (typically factory-set or determined by the boiler's control board), the sensor signals the boiler control to shut down the burner, preventing the boiler from overheating.
• ફરીથી સેટ કરો: Some high limit sensors are manual reset, requiring a physical button press to reset after a trip. Others are automatic reset. Refer to your boiler's manual to determine the type of reset mechanism for your system.
• સામાન્ય કામગીરી: During normal operation, the sensor remains in a closed (or open, depending on design) state, allowing the boiler to function. It only intervenes when an unsafe temperature condition is detected.

6. જાળવણી

Regular maintenance of your boiler system, including its safety components, is crucial for efficient and safe operation. The high limit sensor itself typically requires minimal direct maintenance, but its environment should be kept clean and its connections secure.

• વાર્ષિક નિરીક્ષણ: Have a qualified technician inspect the high limit sensor and its wiring annually as part of routine boiler maintenance.
• કનેક્શન તપાસ: Ensure all electrical connections to the sensor are clean, tight, and free from corrosion.
• શારીરિક નુકસાન: Inspect the sensor for any signs of physical damage, such as cracks, corrosion, or frayed wiring. Replace if any damage is observed.
• Sensor Well (if applicable): If the sensor is installed in a dry well, ensure the well is clean and free of debris that could impede heat transfer to the sensor.

7. મુશ્કેલીનિવારણ

If your boiler is experiencing issues related to temperature control or safety shutdowns, the high limit sensor may be a factor. Always consult a qualified technician for diagnosis and repair.

• Boiler Not Firing / Frequent Shutdowns:
  • સંભવિત કારણ: High limit sensor has tripped due to actual overheating.
  • ક્રિયા: Check boiler temperature. Investigate other causes of overheating (e.g., low water pressure, circulation issues, pump failure). Allow boiler to cool and reset sensor if manual reset type.
  • સંભવિત કારણ: Faulty high limit sensor (false trip).
  • ક્રિયા: A technician can test the sensor's continuity and resistance at various temperatures to determine if it's functioning correctly.
• Boiler Overheating (Sensor Not Tripping):
  • સંભવિત કારણ: Faulty high limit sensor (not tripping when it should).
  • ક્રિયા: Immediately shut down the boiler. This is a critical safety issue. A technician must replace the sensor.
  • સંભવિત કારણ: Incorrect wiring or poor connection.
  • ક્રિયા: Check wiring for secure and correct connections.
• ભૂલ કોડ્સ:
  • ક્રિયા: Refer to your Buderus GB142 boiler's manual for specific error codes related to temperature sensors or high limit conditions.
