Initial commissioning
WARNING!
Risk of explosion from the commissioning of
damaged products
Commissioning damaged products in areas with
potentially explosive atmospheres may lead to an
explosion. This can cause serious or even fatal
injuries as well as considerable damage to prop-
erty.
Before you commission the controller, check it for
damage that could impair the movement of the
damper blade; if the controller has been dam-
aged, replace it.
Before you start commissioning:
Ensure that the device or unit has been cor-
rectly fixed and connected to the ducting.
Ensure equipotential bonding of the device or
unit.
Ensure that the devices or units as well as the
ventilation system are clean and that there are
no residual matter and foreign objects.
Important:
If there is a risk that the controller
could be subject to mechanical impact during
operation, protect it accordingly; protection has
to be provided by others.
For commissioning see also VDI 6022, part 1 – 'Hy-
giene requirements for ventilation and air-condi-
tioning systems and units'.
WARNING!
Risk of explosion!
Ignition sources, such as sparks, open flames or
hot surfaces, can lead to explosions in an area
with potentially explosive atmospheres.
–
Get written permission before you start
working in an area with potentially explosive
atmospheres.
–
Do not carry out any work in a potentially
explosive atmosphere.
To remove any potentially explosive atmos-
phere, purge the system with fresh air
before you work on it.
–
Use only tools that have been approved for
use in areas with potentially explosive
atmospheres.
Failure to comply with these safety notes may
lead to an explosion.
Sufficient duct pressure must be ensured for all
operating conditions and for all control units. The
measurement points for fan speed control must be
selected accordingly.
Setting the volume flow rate
Loosen the wing screw (Fig. 1/2) and set the
volume flow rate on the scale (Fig. 1/1).
Lock the scale in the required position with
the wing screw (Fig. 1/2).
No further measurement or adjustment is
necessary.
