摘要：<p>The electronic monitor for gas fired appliances does not use mechanical components, such as setting clock or open relay contacts. The safety closing system is tripped additionally with a gas leakage detector. The gas is ignited by application of supply voltage. In case of successful ignition the electronic control system switches the gas appliance to normal operation. In case of supply voltage failure the monitoring system records a disturbance. In this case the safety circuit closes directly the safety valve. The latter can be opened after the previously carried out ignition process. The safety circuit is controlled also by a gas detector which switches the safety valve off in case of gas leak.</p>
