Circuitry in the ignition module sends 24 VAC to the gas valve via a normally closed high-limitswitch and, in fryers with built-infiltration systems, a normally closed drain safety switch. Simultaneously, the module causes the ignitor to spark for 4 seconds to light the burner. A flame sensor verifies the burner ignition by measuring the flow of microamps through the flame. If the burner does not light or is extinguished, current to the ignition module is cut, the gas valve closes, and the ignition module “locks out” until the power switch is turned off and then back on. A probe monitors the temperature in the frypot. When the programmed setpoint temperature is reached, resistance in the probe causes the heat cycle circuitry in the controller to cut off current flow through the heat relay. This in turn cuts off the 24 VAC to the ignition module, causing the gas valve to close These standard interface boards are also used in a number of fryer types besides the H50 Series.
