forbidden until it has been established that this product has been set
up and wired according to the guidelines for machinery. The
standard "Machine safety" must also be observed.
–Unauthorized modifications to the product exempt the manufacturer
from any liability from resulting damage.
–The relevant accident prevention regulations, as well as other
generally recognized safety regulations, occupational health and
structural regulations are to be observed.
–Furthermore, the country-specific safety regulations also must be
observed.
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.

Product description
Intended use
This gun control unit is designed exclusively for controlling the Gema
powder coating guns as well as for the powder transport by means of the
integrated injector (see also in chapter "Technical data").
Fig.
1
Usually, this control unit is used in automatic plants in connection with the
MagicControl 4.0 plant control. The actual operation as well as the error
message display is done on the plant control, then.
Observance of the operating, service and maintenance instructions
specified by the manufacturer is also part of conformity of 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 considered non-compliant. 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 too.

Air flow rates
The total air consists of conveying air and supplementary air, in relation to
the selected powder quantity (in %). As a result the total air volume is
maintained constant.
OptiStar All-in-One (CG22-C)
Conveying air flow rate
0-5.5 Nm³/h
Supplementary air flow rate
0-5.5 Nm³/h
Electrode rinsing air flow rate
0-5.0 Nm³/h
The total air consumption for the device is determined based on
the configured air values.
These values apply for a control pressure of 5.5 bar.
The max. total air consumption during the coating operation is
< 5,5 Nm³/h:
Total air = 5 Nm³/h (conveying air + supplementary air)
Electrode rinsing air = 0.1 Nm³/h (flat jet nozzle).
