9.1.3 system faults
These faults are indicated with a letter, occasionally followed by a number. To avoid confusion in the
indication, the letters and numbers are fixed as follows:
9.2 RVA 47 Fault Indication
● If the sensor or burner modules connected to the RVA 47 controller fail or are removed from the
circuit, an error message will be displayed on the left of the LCD screen.
● Error Message Notation ER
● Once an error message is present the cause of the error can be traced by accessing function (50).
● To access function (50), open the flap of the controller and press down arrow button twice. (50)
should appear in the left-hand side of the LCD display.
● The figure shown in the centre of the screen is the fault identification number. The display can hold a
number of faults but will only display 2 at any one time. The second error can be accessed by pressing
the + or – buttons.
● Once a fault has been rectified the error number will disappear or be replaced with another fault
number if further attention is required.
The fault identification numbers are detailed below:
E1 Fault with flow sensor
E2 Fault with cable for gas valve or gas valve coil
E3 Fault with rectification circuit
E4 Burner control circuit board has a fault
– – Communication via RS232 connection possible
E5 Parameter fault
E6 Communication fault
