Commissioning
Prior to the first commissioning all installation works have to be carried out, as they
are described in the previous chapter
.
------------------------------------------------------------------------------------------------------------------------------------
AViTEQ delivers magnetic vibrators including the appropriate controllers. Before
commissioning, please check that the magnetic vibrator is only operated with a
matching controller!
------------------------------------------------------------------------------------------------------------------------------------
------------------------------------------------------------------------------------------------------------------------------------
It is totally prohibited that the current consumption of the magnetic vibrator exceeds
the value of the nominal current specified on the type label, because this may lead to
destroying the magnetic vibrator.
------------------------------------------------------------------------------------------------------------------------------------
We recommend to fill the hopper prior to commissioning and to keep the outlet
opened.
Loosen the locknut at the impact bolt and screw the impact bolt into the vibrator plate
until an air gap of some 5 mm exists between the impact bolt and the impact plate.
------------------------------------------------------------------------------------------------------------------------------------
Danger of crushing! Danger of crushing the fingers in the area of the air gap
between the impact bolt and the impact plate during operation.
------------------------------------------------------------------------------------------------------------------------------------
The commissioning procedure must be carried out using the lowest working stroke:
Turn the vibration-width adjuster (potentiometer) on the controller counter clockwise
till you reach the end stop (scale value of 0) or, if you use an external command
value, set the lowest command value. Now switch on the controller.
Listen for any hammering noises that indicate the collision mode.
------------------------------------------------------------------------------------------------------------------------------------
It is not allowed to operate the magnetic vibrator if hammering noises exist! Collision
mode will lead to destroying the magnetic vibrator. Please ask us in the case of doubt.
------------------------------------------------------------------------------------------------------------------------------------
Slowly increase the working stroke by gradually turning the vibration-width adjuster
(potentiometer) or by increasing the external command value, until the maximum
value has been reached.
If hammering noises occur, switch off the unit and check the cause. By measuring
the current on the terminals of the appropriate controller, you can check the related
value.
------------------------------------------------------------------------------------------------------------------------------------
Short circuit or danger of electrocution during the following measurements! Observe
the safety regulations when measuring voltage-carrying components! Take
appropriate measures to prevent contact with voltage-carrying components.
------------------------------------------------------------------------------------------------------------------------------------
The current that is shown on the type label must not be exceeded! Additionally you
can measure the vibrator voltage and compare it with the value that is shown on the
appropriate characteristics curve data sheet.
