14.4 Setting the position of servo VIGAS
Lambda Control
boiler
Correct setting of servo and flap for secondary air control is a key factor for burning with minmum
emission. Servo and flap can be set in follows:
Step1: Disconnect power wire from distributing network
230V/50Hz,
Step2: Loose screw „1“ with fork wrench,
Step3: Turn the shaft with screwdriver „2“ to maximal
position, anti-clockwise and push softly in direction to the
boiler, shaft must be rotate easily!!!
Check the flap movement in hole „3“,
Step4: Draw close screw „1“
Step5: Connectpower wire into distributing network
230V/50Hz. Automatical initialization, indicated on display, starts when power wire is connected
into distributing network. During initialization servo will be pushed. When boiler is activated to
„ON“
mode, flap will be moved to opposite position in anti-clockwise direction, where is
controled eighter primary and secondary air to requested value
λ
.
14.5 Setting the position of secondary air flaps of VIGAS boiler
The quality of burning can be increased by secondary air
flaps. VIGAS
Lambda Control
boilers regulate amount of
secondary air automatically, therefore the quality of the
burning is high. In VIGAS boilers withouth lambda sensor is
adjusted with screws „1“. Optimal settings form production
is adjusted to 2,5 turns „1“. When change or check the
setting follow the steps:
Step1: „1“ loose the safety nut,
Step2: Draw close screw „1“ in direction to the boiler,
Step3: Loose the screw, back on 2,5 turns (optimum),
Step4: Draw close the safety nut.
Boiler without lambda sensor, safety flap is located above the
fan „2“, that avert burning without fan (chimneay draught). If
boiler has lack of output , check flap functionality „2“.
14.6 Lambda sensor and gases thermometer
Cleanness is important for correct functionality of lambda
senosor and gases thermometer. Gently wipe dust from
lambda sensor „1“ and gases thermometer „2“, when
cleaning.
Important: Gases thermometer must be in correct
position. Correct position of gases thermometer „2“ –
end of the metal gases thermometer must be together
with end-socket.
(to change the position of the gases
thermometer, indicated value will be changed significantly).
Disconnect („3“ and „4“) gases thermometer or lambda
sensor if changed. If boiler does not contain terminals „3“ and „4“ disconnection must be realized
directly from mother board AK 3000S.
