Commissioning; Checks Before Commissioning; Checking The Direction Of Rotation - Grundfos 384-511 Montage- Und Betriebsanleitung

To ensure electromagnetic compatibility
(EMC), the signal cables must be shielded.
The screen must be connected on one
Caution side to PE (earth) or to the housing earth
(earth terminal).
Lay signal and mains cables in separate
cable channels.
For parallel operation: If several drives are
controlled via a shared contact, e.g. if
Caution
there are two servomotors on one duplex
pump, every drive must be equipped with a
relay for parallel operation.
Lay the mains supply lines with
Note
cross-sections that conform to the relevant
VDE guidelines.
Use separate, shielded lines for low
Note
voltages (e.g. potentiometers, analogue
signals).
Use screwed cable joints appropriate for
the connection line.
Note
The stated degree of protection can only
be ensured if suitable screwed cable joints
are used.
Warning
The internal wiring of the drive must never
be modified.

10. Commissioning

Warning
The drive may only be commissioned if the
hood and cable entries are properly
closed.
Warning
Please note that the process of
commissioning the drive will cause
associated fittings/levers/rodding to move.
Warning
Check that all emergency
equipment/functions on your
machine/installation are working correctly.
Warning
Once all adjustment work has been
completed, check that the drive and the
fittings/levers, etc. operated by it are
working correctly.
Warning
Never work with a damaged drive.
When commissioning, all the installation's
Caution
components must be ready for operation.
Follow the installation and operating
Note
instructions for the components used.

10.1 Checks before commissioning

Before setting the servomotor to automatic
Caution operation, check the min./max. position
and the direction of rotation.

10.1.1 Checking the direction of rotation

The servomotor is controlled by an external
controller. This means that the servomotor's direction
of rotation depends on the controller's cabling and
settings being correct.
Observe the installation and operating
Note
instructions for the controller and the
dosing pump.
