Electrical Panel; Positioning The Rpm Sensor - Riello RS 1300/EV C01 Modulating Operation

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. 35).
D9174
Gas leaks
Make sure that there are no gas leaks on the pipe between the
gas meter and the burner.
Gas filter
Change the gas filter when it is dirty.
Combustion
In case the combustion values found at the beginning of the inter-
vention do not respect the standards in force or, in any case, do
not correspond to a proper combustion, contact the Technical As-
sistance Service in order to carry out the necessary adjustments.

Electrical panel

Turn off the burner's power 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. 36;
 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.

Positioning the rpm sensor

In the event the rpm sensor is malfunctioning or
needs replacing, check/reset its position inside
the fan motor cover.
WARNING
To adjust, proceed as follows:
 loosen the screws 3) and rest the sensor against the plate of
CO the disc 2);
 referring to the scale 4) draw back the rpm sensor by about
a notch so that there is a distance of about 2 mm from the
disc plate 2).
 Having correctly positioned the RPM sensor 1), tighten the
 100
screws 3) with a torque of approximately 5±0.5 Nm.
