FREQUENCY
VERIFICATION /
CONTROL
MODALITIES AND CHECKS
At least half-yearly
Verify the efficacy:
¾
Of the equipotential
circuit and protection
connections
With adequate instrumentation the resistance must be measured and
checked towards equipotential plant mass, protection and of every
connection, so that the measured values are in the acceptability
limits defined from the installation standards and in accordance
with the actual disposals of the installation place.
In the prescriptions ambit – above indications, the correlative
grounding plant must be in conformance with the applicable
requirements for the coordination with the associated active
devices, in accordance with IEC364_5_54 / HD382_5_54 / CEI
64.8 (5_54) (last issues).
At least half-yearly
Verify
:
¾
The motors electric
insulation
With adequate instrumentation the motors insulation resistance
must be measured and checked, so the measured values are in the
acceptability limits defined from the installation standards and in
accordance with the actual disposals in the installation place.
At least half-yearly
Verify
:
¾
the absorption in the
single phases of the uses
and motors
With adequate instrumentation the absorptions must be measured
on every feeding conductors of uses and motors.
In the case in which the pointed out values during the normal
functioning are not included in a range of 10% of the values
showed in the electric diagrams of feeding and control/check,
activate the maintenance service with the aim to verify all further
use/motor characteristics, because this could in short time damage.
At least yearly
Verify the efficacy:
¾
of the connections and
electric components
within and outside the
covers
Verify the absence of possible releases. If present restore the
connections in durable way tightening the connections with
adequate torque and carried back directly on the electric
components.
The control must besides regard:
¾
the derivation boxes integrity, of the covers, of the push-button
panels and the electric cables protection cases;
¾
the functionality of all control and power actuators.
The possible change must happen with original products of the manufacturer or at least of same quality, safety and
characteristics. For information contact the Authorized Assistance Centre.
6.4.
EXTRAORDINARY MAINTENANCE
For the interventions of
extraordinary maintenance and parts change
, consequent to breaks or revisions or mechanical or
electric damages, it is necessary an intervention request to the Authorized Assistance Centre.
The instructions about the extraordinary maintenance are not present in the actual instructions manual for the use
and
so must be clearly requested to the Authorized Assistance Centre.
For the selling of worn and changed materials,
make reference to the prescriptions of the chapter 7.
It specifies besides to:
1.
Not try any change and/or reparation of significant elements.
2.
Not perform any welding of parts eventually damaged.
3.
Not use ever the machine if it isn’t in its full efficiency.
After important reparation interventions or parts change,
before of the successive refunctioning, a positive
result, the controls, recordings and verifications showed in the chapter 4, 5 and 6 must be performed and
checked.
For the worn and changed materials selling,
make reference to the prescriptions of the chapter 7.
