Bentone MVD 210 - Function LME

15 Bentone
3.2.1 Component list
3.3 Function LME...
1. Operating switch ON-Thermostat ON-Gas pressure switch ON
A check that the air pressure switch does not indicate fan pressure is
carried out.
2. Burner motor starts
A check that the air pressure switch indicates sucient fan pressure is
carried out.
3. The ignition spark is created
4. The gas solenoid valve is open
The gas is ignited. The ionisation electrode now indicates a ame.
5. The safety time expires
The ignition spark ceases. The safety period ceases. If the spark is missing
or it disappears after this time limit, the gas burner control is blocked.
6. Operating position
The burner is in operating position and can now change over to full load
if the operating switch and the thermostat for full load are in positon ON.
The burner can alternate between full and low load depending on set
temperature.
7. Stop
The operation of the burner can now be stopped with the control switch or
thermostat.
If the gas burner control is blocked
Red light in the gas burner control is lit. The burner is restarted by pushing
the reset button.
