Functional description
The
Lubo-DryExx
®
metering stations are equipment for the automatic application of
DryExx
®
conveyor belt lubrication systems with lubricant.
4.1
Description of
DryExx
®
System (Hardware)
The
DryExx
®
System consists essentially of an metering station with a diaphragm
compressed air pump, a control unit as well as the standard piping and nozzle system.
Various types of control unit are available dependent upon the size and specification of
the installation.
The standard supply and piping system is produced in stainless steel, but PE piping is
available as an option. The distribution circuit is in line with the requirements of the
installation and where it is sited, but essentially is a wet lubrication system. The
maximum number of nozzles for each lubrication circuit should be a maximum of 50-60.
The standard nozzle system has welded nozzle fittings For conveyors with more than
two tracks, the number of tracks - 1 is used to calculate the number of nozzles. The
inserted nozzles have a throughput of approx. 3 litres per hour at a spray pressure of 2
bar. In order to prevent leakage over time from the nozzles, ball-bearing valve filters with
an opening pressure of 1.4 bar are used.

Description of Control System
DryExx
®
Advanced
DryExx
®
Advanced
is a control for dry belt lubrication systems model
DryExx
®
in the milk
and drinks industry, The control system is based on a Siemens PLC S7-300 with a
TP170B panel in stainless steel housing and controls all required times, cycles,
procedures and reports in
DryExx
®
Systems with up to 16 lubricating cycles in max. 10
plants. The
DryExx
®
Advanced
works exclusively together with our metering stations
„
Lubo-DryExx
®
“.
The control system includes the following functions:
Free allocation of valve outlets for systems 1 - 10
Activation of pneumatic membrane metering pump with external release and if a spray
phase is active
Release-dependent automatic operation
Separate manual activation of one spray phase for each belt lubrication phase (For
example, for filling the system. This function may have to be used repeatedly until the
entire system is full)
Activation of magnetic valves with individual time settings for each lubricating circuit
Status, parameter, and archive display via the TP170B panel
Simple operation using the function keys of the TP170B panel
Discontinuation of functions when empty, issue of error message
Operating hours counter for each lubricating circuit
Quantitative entry of quantities for conveyor belt lubrication medium (optional)
Quantitative entry of quantities for containers (optional)
Archiving of operating data for the current day and month and for the previous 12
months
NOTE
The
DryExx
®
Advanced
control system is available with german and English display
texts.
When you follow the instructions for changing values, a numerical keyboard opens to
allow you to make the settings. The system only adopts the changed values and returns
to the relevant screen when you press the ENTER key.
