Important points before using the Shokouh Double Valve Gas Safety Relay G790

• 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 G790 controller relay replaces another relay (other than the G790), 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 Double Valve Gas Safety Relay G790

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.
• The 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 terms of Shokouh Double Valve Gas Safety Relay G790

Replacement, installation and service should be done by qualified and authorized people

Conditions that cancel the relay warranty are:

• Lack of warranty card and floor sticker
• Burns, breakdowns and deformations due to overheating or over-voltage
• Impact of severe mechanical shocks
• Manipulation and repair of relay circuit and opening of the frame
• Improper wiring or fault in the burner that burns part of the internal circuit of the relay (for example, pins 8 and 9 are closed with 1 and 2 displacement, or pins 4 or 5 or 6 are shorted to the body or ground.)
• Torch motor failure such as delay in starting or failure of its capacitor, or contamination or jamming of the motor shaft which increases the current and pressure to the relay and burns the internal circuit of the relay.
