Product description OptiFeed 4.0 (PP07)
Powder fluidization
The powder pump has a fluidizing air connection ( 6.4 ), which becomes
active when the pump is switched on. The air can be used to fluidize the
powder in a fluidized powder hopper or it can be used locally for a fluid
suction unit.
The equipment required for this should be ordered in
consultation with Gema Customer Service.
– To ensure that the function of the powder pump is not impaired,
the compressed air consumption at the fluidizing air connection
must not be too high, i.e. the inlet pressure must not fall below 6
bar!
Interval operation
To prolong the service life of the pump parts, the pump should not be
allowed to run continually in conveying mode. The interval function allows
specific ON times and time periods to be programmed. This application is
recommended especially when conveying used powder or waste powder.
To activate/deactivate this function, refer to see chapter "System
parameters" on page 35.
To set the length of the duty cycle and period duration, refer to see
chapter "Conveying parameters" on page 43.
Monitoring of the wear parts
Wear parts have a limited service life. The device offers functionality to
monitor the service life of up to four wear parts. Wear part monitoring can
be set and read out on the display or via can bus.
The monitoring of a wear part is either cycle-based or time-based:
Cycle-based
monitoring
The number of operations of the monitored part
is counted.
Wear Part No. 1 = Pinch Valves
Time-based
monitoring
The time the monitored part is in operation is
added up.
Wear part no. 2
– 4 = freely selectable
To better explain this function, a few terms relevant to this process must
first be explained:
Term Explanation
Duration
Actuation cycles or time interval
Operating time
Effective duration during which the wear part
was in operation
Service life
Operating life after which wearing parts should
be replaced (defined by the operator) (See also
"Monitoring of the wear parts" on page 53.)
Remaining
service life
Service life minus operating life (See also
"Monitoring of the wear parts" on page 53.)
Warning limit
Remaining service life below which a warning
is generated (See also "Monitoring of the wear
parts" on page 53.)
