SBS-FMU

Monitoring functions:

Nozzle Pressure (Analog Input 0)
-in Bargraf form & in Real number value

Burner Flow (kg/h) (Analog Input 1 OR tacho signal Digital Input 0.0)
-in Bargraf form & in Real number value, this filed can be hiden if commissioning engineer want to have all adjustment done in the l/h.

Burner Flow (l/h) (Analog Input 1 OR tacho signal Digital Input 0.0)
-in Real number value, this ensures that we can see if we have correct input signal before calculation is performed into kg/h.

Indication of the Selected Fuel:

-HFO / MGO type of the fuel is selected, for this there is 2 field with text for indication

AIR RATIO input field
-ensures end user to be able to lineary make correction to the output +/- 20%

IGNITION FORCING AO Pressure
-This is used for indication that until Main Oil Valves are opened, Nozzle pressure is forcing as a analog output from the SBS-FMU unit. This is used on some systems which are checking that i.e. Nozzle pressure must be over 10kg/cm2 before opening of the Main Oil Valves. This option can be Enabled/Disabled in the Settings 4 screen and also delay alarms can be adjusted.

OUTPUT Type of forward signal
-This is indicating if current output is forward of FLOW or PRESSURE signal. Ensuring that commissioning engineer has information of the real output signal.

Alarm & Indication functions:

BACKFIRE Protection - Flow
-monitor that during MOV Opened (DI0.7) Flow thru nozzle is less then Sepoint Value in time interval defined in the Settings page. Value can be adjusted in the Settings screen. For which you need password.

BACKFIRE Protection - Pressure
-monitor that during MOV Opened (DI0.7) Pressure of nozzle is less then Sepoint Value in time interval defined in the Settings page. Value can be adjusted in the Settings screen. For which you need password.
