Maintenance / Repairs OptiSpray AP01.1-E
Maintenance of the dense phase pump
Maintenance schedule
The following components or modules are subject to a maintenance plan:
–
Pinch valves
–
Filter elements
The service life of the filter elements and pinch valves depends on the
service duration, the powder quality and the quality of the air supply.
Daily maintenance
Clean the Application pump with a dry cloth and check the connection
points of the powder hoses. Replace the powder hoses, if necessary.
Rinse the Application pump by using the rinsing program. Therewith, the
filter elements are cleaned and possible, unintended powder deposits in
the Application pump and in the powder hoses are avoided.
Pinch valve diagnostic
The pinch valve diagnostic is to be carried out, in order to maintain the
coating quality or after the error message
H89 is displayed.
The prerequisites for the diagnostic:
–
Exhaust at suction and conveyance side must be present and in
operation
–
Powder hopper must be empty
–
Cleaning program completed
The pinch valve diagnostic is to start after the cleaning program
has been completed!
– The detailed procedure is explicitly described in the CG24-CP,
CG23-P, CG12-CP or CG11-P Gun control unit operating
instructions.
If the error message H87/H187 (suction pinch valve) or H88/H188
(conveying pinch valve) is displayed after the procedure has been
completed, the corresponding pinch valve hoses must be replaced
– see
below.
