Do not operate the spray gun's trigger while the control unit is being switched on
and is powering up.
The EPG-SPRINT XE control unit automatically detects whether a manual or automatic gun is
connected to the control unit (parameter C26 must be set to OFF). It does this by checking
whether the trigger switch is activated when it is switched on.
– If the trigger switch is pressed, the gun is an automatic one. The powder feed is switched
on and off by a superordinate controller via the remote interface.
– If the trigger switch is not pressed, the gun is a manual one. The powder feed is switched
on and off with the gun's manual trigger.
7.2.4 Manual Gun Mode with External Control
Application is the recoating of work pieces in an automatic coating system. The recoating is
done with a manual gun, but the powder feed is done by the powder center of the
automatic system. The EPG-SPRINT XE must receive a release signal via the remote interface
so that the device may clean and coat. The cleaning function (continuous flushing) can also
be controlled externally.
Display on device:
[Automatic gun] LED flashes quickly
No release signal is present
[Automatic gun] LED is off (not lit)
Release signal is present
This operating mode is available starting from software version B200. The function must be
selected specifically via configuration parameter C26.
7.2.5 Basic and Factory Settings
The EPG-SPRINT XE control unit is factory-configured for operation with Corona manual or
automatic guns. Consequently, the control unit can be used in a manual system or an
automatic system without any further settings being required.
However, if the control unit is used with a Tribo manual or automatic gun, the gun type must
be changed. This change is made in the configuration settings.
For all other settings, configurations and special functions, please refer to Chapter Appendix
Device Configuration [
68].
7.3 RECIPES
Recipes are used to avoid lengthy adjustment work when changing powder or work piece.
All parameters relevant for coating a work piece are combined and stored under a recipe
number instead.
