EPG S2
OPERATING MANUAL
VERSION 09/2017 ORDER NUMBER DOC2317574
The de ned eld of application should only be seen as a guideline and must be adjusted to
the type of powder, the distance to the work piece and the work piece geometry.
The combination of high-voltage setting, current limitation and characteristic slope results
in a large number of settings options for each coating situation.
7.5.4 SETTING THE AIR VOLUME
The set point air volume in all 6 channels on the control unit can be set independently of
each other and the actual air volume measured can be shown on the central controller.
The air volume can be set in 0.025 Nm³/h steps between 0.00 Nm³/h and 6.00 Nm³/h. Note that
depending on the application, cases may arise where the maximum ow rate cannot be
reached. In this case, the control unit will issue a warning and the maximum set point must
be reduced.
These maximum values can be found in the instructions for the various injectors and guns.
7.5.5 AIR SUPPLY PRESSURE
The EPG S2 control units are calibrated in the factory to a primary pressure of between
0.6-0.8 MPa; 6-8 bar; 87-116 psi. It is important that the atmospheric pressure supply
line has a large cross-section and that the air supply pressure does not drop during high
demand.
