Grounding - WAGNER PER-X1 Translation Of The Original Operating Manual

Operating manual Robot powder spray gun PER-X1
6 Assembly and Commissioning
Assembly:
1. Screw the connecting piece to the robot arm using the screws (6x).
2. Pull the union nut over both gun handles (as shown) and screw the guns to the gun
connection.
3. Guide both connection cables as well as the powder and atomizing air hoses through
the robot arm and connect to the guns.
4. Mount the robot guns on the connecting piece using the union nut and secure the
union nut with the stud (X).
Disassembly:
Note: Disassembly is carried out in reverse order to assembly!
Before replacing the robot spray gun, any powder residue must be thoroughly removed.
The wearing parts in the robot spray gun, marked in the spare parts list with "♦", must be
regularly checked and replaced as necessary.
1. Loosen stud and unscrew the union nut from the connecting piece.
2. Pull both connection cables as well as the powder and atomizing air hoses off of the
robot spray guns.
3. Unscrew the gun connection from the guns.
4. Replace the PER-X1 robot spray gun and assemble it again as described in Assembly.
6.7 GROUNDING
For safety reasons, the control unit must be properly grounded. The grounding connection
to the energy supply (socket) is made via the mains connection cable's protective conductor,
while that to the work piece/system is made via the knurled screw on the rear of the control
unit. Both connections are absolutely essential. The gun is grounded according to
instructions for proper commissioning.
Good grounding of the work piece is also necessary for optimum powder coating.
A poorly grounded work piece causes:
– dangerous electric charging of the work piece
– very bad wrap-around
– uneven coating
– back spraying to the spray gun, i.e., contamination
Prerequisites for perfect grounding and coating of a work piece are:
– Clean suspension of the work piece to be coated.
– That a grounding resistance of the work piece of 1 MΩ is not exceeded
(resistance to ground measured at 500 V or 1000 V).
Sparks between conveyor, conveyor hooks (hangers) and work piece can occur if
electric contact points between conveyor, conveyor hooks (hangers) and work piece
are not sufficiently cleaned and therefore the work pieces are not sufficiently
grounded! These sparks can cause heavy radio frequency interference (EMC).
