Important points before using the Shokouh diesel relay model TF701

• Be sure to check the wiring before use. Wrong and defective wiring and wiring can be dangerous and cause irreparable damage.
• Note that if the 811 controller relay replaces another relay (other than the 811), it may be necessary to change the wiring.
• Make sure that the connection screw is tight when using the controller to ensure that the controller is fully connected to the relay base.
• It is necessary to use a suitable fuse in accordance with the technical specifications of the controller. And that the main fuses must be selected in such a way that they operate and cut off the power before the current reaches the nominal values ​​in the technical specifications of the relay. Otherwise, in the event of a short circuit in any part of the burner equipment, severe damage to the controller, burner parts or the user may occur.
• Each controller must be turned off at least once in 24 hours.
• To install and replace the controller relay, the main power switch must be disconnected and the burner must be disconnected from the power supply system.
• Strictly avoid opening or repairing the controller.

Troubleshooting Shokouh diesel relay model TF701

Problem 1: The torch does not start

solution:

• Check the power connection
• Check the status of the fuses
• The thermostat is OFF
• Gas pressure is OFF.
• Check the wiring
• A damaged fan or fan connections is like a damaged or out-of-circuit starter capacitor.
• Basic wiring is wrong.
• Contamination of 9 or 8 or 4 pin pins

Problem 2: The controller goes into the error phase immediately after starting the torch:

solution:

• There may be a short circuit between pins 2, 8 or 2 and the burner body.
• The UVZ sensor may be damaged or a short circuit may have occurred.
• Check the reset lock (press the reset button only once)
• The supply voltage is less than 180 volts.

Problem 3: The controller opens the fuel valve after starting and during the discharge time, but no flame is formed

solution:

• Check the input power cables to the spark transformer
• Check pins 3 and 8 for safety and contamination to ensure proper connection.
• Check the relay command to ignite the transformer at discharge. (Check the voltage of pin 3 of the base at the time of discharge.)
• Check the high-voltage voltage cables of the ignition transformer output. Inspection of cables should be checked in terms of health, quality and insulation, observing a radial distance of 1 cm from each other and a distance of more than one cm from any metal and wall of the burner.
• Under no circumstances should two spark voltage cables be next to each other.
• The total length of high voltage spark transformer cables should not exceed one meter.
• Spark electrode tip distance exceeds standard (3 mm for gas burners)
• Insulation or material of spark electrodes or quality of spark electrode cables is not suitable.
• Check the burner transformer for power and health during discharge. (Light sound at spark time)
• Check the fuel nozzle and the correct direction of fuel distribution according to the relevant burner catalog
• Adjust the air valve
• Check the output of the boiler, burner, ventilation and chimney.
• Check the gas regulator
• Check for fuel

Problem 4: The controller opens the fuel valve after starting and during the discharge time, a flame is formed, but after the assurance time, it enters the fault phase.

solution:

• The fuel nozzle and the correct direction of fuel distribution must be in accordance with the relevant burner catalog.
• Adjust the air valve
• Check the output of the boiler, burner, ventilation and chimney
• Possibility of contamination of pin 2 pin or its path to UVZ sensor contamination
• The earth is disconnected or the burner body is not connected to the standard earth.
• Damaged UVZ sensor or cable disconnected (check pins 2 and 8 to the flame sensor)
• The UVZ sensor is improperly placed in the burner so that it does not see the flame or is contaminated.
• Check the flame quality
• Check the chimney

Problem 5: After the formation of the flame and for a certain period of time, the controller goes into the error phase.

• In a gas burner, this sometimes happens due to a sudden drop in gas pressure (for example, due to the ignition of another burner at close range).
• Check the fuel nozzle and the correct direction of fuel release in accordance with the relevant burner catalog
• Adjust the air valve
• Check the output of the boiler, burner, ventilation and chimney.
• Pin 2 pin or its path to the UVZ sensor is contaminated.
• The earth is disconnected or the burner body is not connected to the standard earth.
• Damaged UVZ sensor or cable disconnected (check pins 2 and 8 to the flame sensor)
• The UVZ sensor is improperly placed in the burner so that it does not see the flame or is contaminated.
• Check the flame quality
• Check the chimney
• Check the voltage

Warranty conditions of Shokouh diesel relay model TF701

Replacement, installation and service must be performed by qualified and authorized personnel.

Conditions that cancel the relay warranty are:

• Lack of warranty card and floor sticker
• Burns, breakdowns and deformations due to overheating or over-voltage
