Application and Brief Description
Controllers STW164IP allow in conjunction with slider controls STW168M and bus modules
STW161M controls extraction systems with up to 32 machines.
The STW164IP control serves as the central control unit. It records the operating state of the machines by
measuring their current consumption in the supply lines (current transformer STWA1 (H)) or via potential-free
contacts.
It switches on the central extraction and opens the sliders on the channels to the individual machines.
8-fold slider modules are used to control the sliders. These can be mounted next to the STW164IP or distributed
in the system. The latter reduces the wiring effort.
Additional sliders can be opened to optimize the air flow. Assignment to different lines and prioritization is
possible.
It is also possible to control cleaning and discharge.
The parameters are conveniently configured via the network (Ethernet). If the control is connected to the
Internet, it can also be parameterized remotely.
The recording of operating hours of the machines and the switching frequency of the valves provide valuable
services for preventive maintenance. In this way, components can be replaced as part of a service operation
before they age and fail.
Application:
Control of extraction systems in the wood and plastic processing industry in accordance with the Technical
Rules for Hazardous Substances TRGS 553. The central automatic start-up system switches on the extraction
system as soon as a machine is put into operation. Shut-off valves in the extraction channels of the individual
machines are controlled automatically. The device can also control filter cleaning (vibrator) and discharge, start
external cleaning (compressed air) and signal when a maximum volume flow is exceeded. STW164IP optimize
the function by opening sliders in the extraction channels only where machines are in operation. In addition, the
analog output can be used to control a frequency converter on the extraction motor. This ensures better
extraction performance, saves energy and offers a high savings potential for the implementation of measures
within the framework of Directive 2012/27/EU (Energy Efficiency Directive).
