Minimum Output - Riello RLS 310/M MX Modulating Operation

Air adjustment
The regulation of the air is carried out by changing the angle of
the cam I) and IV) of the servomotor Fig. 29 and using the selec-
tor 2)(Fig. 30 on page 30).
To adjust the cam of the servomotor, see Fig. 35 A).

6.10.4 Minimum output

Min output must be selected within the firing rate range shown on
Fig. 3 on page 12.
Press the button 2)(Fig. 30) "Decreasing output" and keep it
pressed until the servomotor comes to the minimum position.
Adjustment of gas delivery
Progressively adjust the initial profile of the mechanical cam 2)
Fig. 34, using the screws 2) Fig. 34.
For example, calibrate the minimum output to 800 kW, check the
emissions and if necessary increase or decrease the opening of
the air damper (see "Proceed with the calibration (gas)" on
page 34). Bring the output to 800 kW using the screws 2) of the
mechanical cam (Fig. 32 on page 32) and check the emissions.
Air adjustment
The regulation of the air is carried out by varying the angle of the
cam III) of the servomotor Fig. 29 and by using the selector
2)(Fig. 30 on page 30). To adjust the cam of the servomotor, see
Fig. 35 A).

NOTE:
The servomotor follows the adjustment of cam III only when
the angle of the cam is reduced. If it is necessary to increase
the angle of the cam, you must first increase the angle of the
servomotor by means of the "output increase" key, then in-
crease the angle of cam III, and finally bring the servomotor
to the position of MIN output, with the "Output reduction"
key.
To adjust the cam III) Fig. 29, see Fig. 35 A) and B).
