12 •Safety OptiCenter OC07
Product specific security regulations
– This product is a constituent part of the equipment and is therefore
integrated in the system's safety concept.
– If it is to be used in a manner outside the scope of the safety
concept, then corresponding measures must be taken.
– The installation work to be done by the customer must be carried out
according to local regulations.
– It must be ensured, that all components are earthed according to the
local regulations before start-up.
For further security information, see the more detailed Gema
safety regulations!

OptiCenter OC07 Transport •13
Transport
Introduction This chapter describes special precautions that must be taken during
internal transport of the product if:
– the customer himself must pack, transport and ship the product, in
order to have overhaul and repair work carried out by the
manufacturer
or
– the product must be shipped for disposal (recycling).
Safety rules
Suitable equipment (e.g. a crane) must be used when moving parts that
are sometimes bulky and heavy.
Components being disassembled must be adequately secured before
they are detached.
Requirements on personnel carrying out the
work
Use only technical personnel who are trained in operating the respective
equipment (e.g. a crane).
If there are any uncertainties, please contact Gema Switzerland GmbH.
Packing material
Not necessary for the internal transport. For external transport: see
chapter "Decommissioning / Storage" on page 103.
Transport
Data concerning goods to be transported
– The space requirements correspond to the size of the components
plus the packaging
– Weight see "Technical Data"

Rev. 02 04/21
14 •Transport OptiCenter OC07
– Points of attachment, see "Mode of transportation"
Mode of transportation
For short distances/shifts of position within the same room, the product
must be transported using a forklift truck with long forks.
Fig. 1
Transport the unit only in the position according to its intended use.
ATTENTION
Risk of damage
The OptiCenter must not be placed fully in the horizontal position,
since it is not designed for this purpose.
► In case of doubt contact Gema Switzerland GmbH!
Loading, transferring the load, unloading
Suitable lifting equipment is to be used for all procedures.

Rev. 02 04/21
OptiCenter OC07 Product description •15
Product description
Intended use
The powder management center is designed for easy and clean handling
of the coating powder and is operated via a touch panel.
The center will only operate in combination with Gema powder conveyors,
which are designed to convey coating powder to the spray guns.
As a part of the process controlled coating plant, the center is designed
for automatic or semi-automatic operation. It enables an automated
cleaning process and consequently a quick color change. The design
concept includes all powder conveyors, gun and axis control units, as well
as the complete fresh powder dosing.
Fig. 2
Observance of the operating, service and maintenance instructions
specified by the manufacturer is also part of the intended use. This
product should only be used, maintained and started up by trained
personnel, who are informed about and are familiar with the possible
hazards involved.
Any other use is not considered as intended use. The manufacturer is not
responsible for any incorrect use and the risks associated with such
actions are assumed by the user alone!
For a better understanding of the interrelationships in powder coating, it is
recommended that the operating instructions for all other components be
read as well, so as to be familiar with their functions.

Rev. 02 04/21
16 •Product description OptiCenter OC07
Field of application
The powder management center is suitable for use in plants with a
completely closed powder circuit:
Conveying
– Fresh powder directly from the (original) powder bag
– Fresh powder from a Gema fresh powder system
– Powder directly from the optional powder hopper
– Precision conveying from the OptiSpeeder to the applicators
– Recovered powder is returned to the system or target container
– Powder level monitoring by level sensor(s)
Cleaning
– Automatic internal cleaning of suction tubes, powder conveyors,
powder hoses and guns
– Supply of the recovered powder
– Closed powder circuit – no powder escaping during coating or
cleaning procedure. This prevents powder loss, and the workplace
and the environment remain clean.
Controlling
– No own exhaust air system – the powder management center does
not have its own exhaust air system and will be therefore connected
directly to the after filter
Reasonably foreseeable misuse
– Operation without the proper training
– Use of moist powder
– Insufficient fluidization at the suction point
– Use with insufficient compressed air quality
– Input pressure too low
– Use in connection with unauthorized coating devices or components
