Voltage on the QRI cell
Minimum value for correct operation: 3.5V DC (value on AZL dis-
play at about 50%).
If the value is lower, it could be due to:
–
cell not positioned correctly
–
low voltage (lower than 187V)
–
bad regulation of the burner
In order to measure, use a voltmeter with a 10V DC scale con-
nected as in the diagram (Fig. 44).

Electrical panel
Turn off the burner's electrical supply using the
main system switch.
DANGER
In the event of maintenance/replacement of components in the
lower part of the electrical panel, access is possible via the front
of the panel itself, following the directions below:
unscrew the screws 2) of the control panel 1);
extract the control panel 1) and turn it 90°, hooking it with the
brackets 3) in the profile of the electrical panel as shown in
Fig. 45;
after performing the operation, install the control panel 1) in
the electrical panel with the appropriate screws 2), arranging
the cables present.
Failure to install the control panel 1) in the seat of
the electrical panel, results in the machine's loss
of "IP" protection.
