Technical description of the burner
4.15
Servomotors
Important notes
All interventions (assembly and installation operations,
assistance, etc.) must be carried out by qualified personnel.
Before modifying the wiring in the connection area of the
servomotor, fully disconnect the burner control device from
the power supply (omnipolar separation).
To avoid the risk of electrocution, protect the connection ter-
minals in a suitable manner and correctly fix the cover.
Check the wiring is in order.
Falls and collisions can negatively affect the safety func-
tions. In this case, the unit must not be operated, even if it
displays no evident damage.
Assembly notes
Check the relevant national safety standards are respected.
The connection between the actuator command shaft and
the control element must be rigid, without any mechanical
play.
To avoid an excessive load on the bearings due to rigid
hubs, the use of compensation clutches without any
mechanical play is recommended (e.g. metal bellows-type
clutches).
Installation notes
Arrange the HV ignition cables separately, as far as possible
from the control box and the other cables.
To prevent the risk of electrocution, check that the 230 VAC
section of the servomotor is completely separated from the
low voltage section.
The static torque is reduced when the electrical supply of the
actuator is switched off.
The housing cover may only be removed for short periods of
time for wiring or when making the addressing. In similar
cases, make sure that dust or dirt does not penetrate inside
the actuator.
The top side of the board carries a cover which affords pro-
tection against direct contact. This protective cover must not
be removed! The underside side of the board must not be
touched.
