Initial inspection after delivery
An indispensable task of all technicians delivering the Pneumatic Conveying system
PFT SILOMAT E is the inspection of the machine settings at the end of the first con-
veying cycle. The factory settings can be changed during the first operation. If these
changes are not corrected in time, immediately after run-in, then operating trouble can
be expected.
After putting the Pneumatic Conveying System PFT SILOMAT E into service and
giving appropriate instructions, after about two hours, the technician must always
carry out the following checks / settings:
1. Pressure control
2. Level sensor
3. Connection cable
4. Fuses
5. Plug connections

The conveying system PFT SILOMAT E is a pneumatic, fully automatic conveying
system for transporting ready-mix dry mortar from the silo / container to the cleaning
machine.
Please observe the processing guidelines of the material manufacturer.
The machine consists of carryable single components of small, handy dimensions and
light weight that allow fast, convenient transport.
The following aspects must be observed for operation:
1. Connection worksite power – control box
2. Connection control box – level sensor
3. Connection control box – motor and drive
4. Connection control box – vibrator
5. Connection compressor – conveying container
6. Connection conveying container – cleaning machine
Operating sequence
When the level sensor of the cleaning machine reports “Empty”, the flap opens
(“Open” position) and the conveying container is filled with approx. 55 l of dry mortar
while the silo butterfly valve is open. The vibrator runs at the same time, to support the
flow of mortar from the silo / container.
When the fill time has passed, the flap closes again (“Closed” position). The convey-
ing container is now sealed pressure-tight to the silo / container.
Now the compressor begins to work and blows air through the emulgator filter into the
conveying container. In this way, the mortar is aerated and pressed through the ex-
traction connection of the conveying container into the conveying line and on to the
cleaning machine. Pressure is built up in the conveying line that is monitored with a
safety switch. If it falls below a set value, that means that conveying container and line
are empty. The system completes the conveying cycle and shuts down. As soon as
there is a new signal by the level sensor at the control box of the SILOMAT unit, a
new conveying cycle is started.
The distribution of air can be controlled by hand using the bypass at the conveying
container. In this way the system can be adapted, depending on the mortar (specific
weight).
