The controller (see Figure 3.1 On-board electronics
→
19) is located inside the electri-
cal panel of the appliance and the display may be viewed through the viewing hole on
the front panel of the unit itself.
The Machine Codes generated by the DDC may only be viewed on the display of the
DDC and may be cleared only through the DDC.
Operating codes generated by the controller during the activation phase of the
appliance
If the appliance remains inactive for a prolonged period, it is possible that air is pre-
sent in the gas pipes. In this case the start up may not terminate successfully and the
appliance displays the operating code: "u112" - flame controller fault (see Table 8.1 TA-
BLE OF OPERATING CODES generated by the controller (firmware version 3.100)
→
77)
and after a brief interval the appliance automatically launches the start up procedure
again.
If code u112 is signalled 4 times, the code persists, the appliance locks out the flame
controller and displays the following operating code: "E112" - flame controller locked
(see Table 8.1 TABLE OF OPERATING CODES generated by the controller (firmware ver-
sion 3.100)
→
77). In this case reset is not automatic.
To restore operation of the appliance, carry out a reset of the flame control unit via
menu 2 of the controller: the procedure is illustrated in Paragraph 3.3 RESET OPERA-
TIONS
→
21. After it is reset, the appliance will make a new attempt to activate.
If the appliance locks out several times, contact a Robur TAC by calling the
Technical
Service Department
of Robur S.p.A. (tel. +39.035.888111).
When activation is successful, the appliance is managed by the on-board controller
(see following paragraph).

ON-BOARD ELECTRONICS
The following descriptions refer to the controller with firmware version 3.101.
The appliance is fitted with an
AY10
controller connected to an auxiliary
S70
controller
(see Figure 3.1 On-board electronics
→
19). The
AY10
is installed over the S70 and is
located in the machine’s internal electrical panel.
The AY10 controller controls the appliance and displays data, messages and codes
during operation. Programming, control and monitoring of the appliance take place
by interacting with the display and encoder of the controller. The CAN BUS port con-
nects one or several appliances to a DDC.
