• With the switch on the burner panel at the position “0” and the main
switch on, check, closing the contactor manually, that the motor ro -
tates in the right direction. If necessary, swap the two power cables
for the motor around to change the direction of rotation.
• If using the inverter, see the specific instructions in the quick guide.
• Now switch on the main switch. This powers on the control devi-
ce, and the programmer turns on the burner as described in the
chapter "Operation description". For burner adjustment, refer to the
instructions for the electronic cam supplied.
• After having adjusted the “minimum”, (200) turn the burner gradually
to maximum, by using the controls on the electronic cam keyboard.
• Check combustion using the appropriate instrument at all interme -
diate points on the modulation route (from 200 to 999), checking the
gas flow rate by reading the meter.
• Now check the proper automatic operation of modulation. This en-
sures that the equipment receives the signal from the electronic
modulation regulator, if the burner is the modulating model, or from
the second stage thermostat or pressure switch, if it is a two stage
progressive burner.
• Check combustion using the appropriate instrument at all interme -
diate points on the modulation route (from minimum to maximum
load), checking also the gas flow rate reading the meter.
• Now, check for the efficiency of automatic modulation operation by
switching the ETAMATIC apparatus to the “AUTOMATIC” position.
With this setting the modulation function will start only by using the
automatic control of the boiler probe.
FLAME SENSOR
Verify the flame detector operation as follows:
• extract the photocell from its seat;
• start the burner;
• the equipment will complete the control cycle and after two seconds
will lock out the burner due to the lack of ignition flame;
• switch off the burner;
• re-connect the wire to the ionisation electrode.
• This test should also be conducted with the burner already on; the
apparatus should shut down immediately when the wire from the
ionization electrode is disconnected.
• check the efficiency of the thermostats or boiler pressure switches
(they should shut down the burner when triggered)
AIR PRESSURE SWITCH
The air pressure switch stops the equipment operation if air pressure
is not at the expected value.
The pressure switch must therefore be adjusted so that it is triggered
to close the NO (normally open) contact when the air pressure in the
burner reaches a particular value.
If the air pressure switch does not detect a pressure greater than that
calibrated, the equipment runs through its cycle but does not switch on
the ignition transformer and does not open the gas valves and so the
burner “locks-out”.
To ensure correct operation of the air pressure switch you must, with
burner on and in 1st stage, increase its regulation value until the burner
triggers and then it immediately “locks-out”.
Release the burner by pushing the appropriate button and readjust the
pressure switch to a sufficient value to detect the existing air pressure
during the pre-ventilation phase of the first stage.
Air pressure sampling point is downstream the air damper.
