Start
Blower
In cases where the blower is equipped with air intake
regulator on the air intake, remember to lock it in the
start position before starting the blower. The air intake
regulator is limiting the blower's air capacity in order
to lower the load on the motor and thereby the
consumption of amp during the start.
Rotary valve
Start the rotary valve when the blower has reached
full speed. (The blower can also be delivered with
automatic start of the rotary valve).
Start
Conveying
Note: It is only necessary to lock the air intake
regulator if the reduction in amp consumption is
demanded by the local power supply.
When the blower is fully running, release the air
intake regulator again (TRL 500 can be delivered with
automatically controlled air intake regulator).
When working, the air intake regulator maintains a
uniform air volume, even when the back pressure
varies during operation. This reduces the load on the
blower motor. The air intake regulator is sealed from
the factory and must not be adjusted.
When the blower is fully running the motor should
always run on delta.
The conveying capacity is regulated by means of the
intake shutter on the rotary valve. For blowers with
air intake regulator the biggest capacity is reached by
slowly opening the intake shutter of the rotary valve
until the indicator on the blower intake regulator is
about 10mm (3/8 in.) from the left stop. For blowers
without air intake regulator maximum capacity can only
be achieved by trial and error.
Venturi
The venturi is self-regulating. It does not take in more
material than the blower can cope with. Where the
venturi is provided with an intake shutter, this must be
opened fully when the blower is started.
Stop
If possible, run the pipe system clean before stopping
the blower. The rotary valve must therefore either be
stopped before the blower or at the same time. Never
stop the blower before the rotary valve as this can
cause the pipe system to block.
Even in cases where the piping system is not clean
when the blower is stopped, this normally will not
cause problems. It is therefore also possible to
keep the rotary valve/venturi in the same position
while starting and stopping the blower.
