1) Troubleshooting the signal lamp of the baker. If the lamp should be on, but not on, check whether the wiring is firm, check whether there is voltage at the lamp end. If the voltage is normal but the lamp is not on, the lamp is broken, replace it Span>
2) Thebutton is faulty, check the wiring, and then the circuit is normal. Check that it opens when pressed. If it doesn't work, it means the button is broken and needs to be replaced Span>
Bakers
4) Baking machinemotor fault check: if the motor is powered on (the contactor is normally closed and the output voltage is normal), check whether the motor wiring is correct, check whether the motor is powered on, if the motor is not powered on, then the contactor of the motor, if the motor circuit is faulty, carry out corresponding treatment. If the motor is not powered on, check the motor winding, insulation and machinery. If damaged, replace the motor. Check the machine and take corresponding measures if it is caused by the machine Span>
5) Troubleshooting of thesolenoid valve, check whether the pressure reducing valve is faulty, if so, carry out corresponding repair or replacement, adjust the outlet pressure to the appropriate pressure, check whether the air path is normal, if not, repair the air path. Check the solenoid valve coil for open circuit and replace it. If the solenoid coil is sucked in by electric energy, but the valve does not move, the valve core is stuck, repaired or replaced Span>
6)Troubleshooting of the control valve, first of all, check whether the air supply of the baker is normal, the air supply pressure should be 0.4-0.6MPA, check whether the valve "] positioner is normal, and whether the 4-20MA control signal can control the air pressure output of the valve positioner. If the valve positioner has no air pressure output, it is linear. Replace or repair. If the valve positioner is normal. The regulating valve does not move. It may be the valve core card. Use manual or appropriate force to pry it up. If the conventional method cannot solve the problem, replace the regulating valve Span>
7)Eliminate the fault of the stop valve, check the air source of the toaster, check the solenoid valve, and the air source pressure drives the action of the cylinder. Considering that the gas is relatively clean, the possibility of the valve plate getting dirty is very small, most of which are cylinder card faults, so repair or replace them accordingly Span>
8)Other types of mechanical failures, such as air leakage and jamming, should be handled according to mechanical common sense on the premise of ensuring safety Span>
9)Instrument pressure transmitter, thermal resistance, distributor, temperature transmitter and pressure controller are damaged and should be replaced accordingly. When the thermocouple is disconnected, there will be an alarm on the screen, which can be short-circuited at the input end of the temperature transmitter. The toaster can eliminate the alarm span>
