Data Sheet 09.03
• Versatile, high-performance Ex-class motor drive with compact dimensions for numerous applications
• This data sheet also incorporates the installation and operating instructions
• Applications:
The Ex-class motor drive is mainly intended for operating wipers on sight glasses and is suitable for short- or long-term operation.
• Special advantages of the Lumiglas Ex-class motor drive:
Especially in environments that require the remote monitoring of processes in reactors (e. g. biogas plants), ex-type cameras are frequently mounted on sight glasses, enabling process engineers to observe what is going on in the vessel from a central control room, which is frequently located at some distance from the
reactor itself.
This eliminates the need for physical presence at a reactor,
frequently entailing safety-relevant situations made more
difficult by adverse environmental conditions, e. g. bad weather.
In certain processes, problems can arise if there are deposits of the substance in the reactor on the sight glass screen, thus making it difficult or even impossible for the camera to view the process. This can be remedied by using one of the proven wipers from the Lumiglas range: Type SWI (data sheet 02.01) and
Type SWII (data sheet 02.02). These wipers are normally operated by hand when the observer wants to inspect the reactor.
In many cases, however, the remote observation of reactors,
e. g. via Lumiglas camera technology, is mandatory, making it essential to install a motor-driven wiper that can be actuated remotely from the control room.
The Ex motor drive Type EMA I-Ex has been developed specifi-
cally for such applications.
Because remote observation is mainly carried out in potentially explosive environments, an Ex-class motor drive is now available in addition to the Ex camera.
• Small dimensions, great effectiveness:
The Ex-class motor drive is designed for both short-term and
continuous operations.
• All development targets have been achieved:
Compact overall size; high turning moment; excellent motor power; low energy consumption.
The Ex motor drive is thus ideally suited for operating, for instance, Lumiglas screen wipers:
a) Type SW I (the wiper blade axis passes through a hole in the sight glass) – for low pressure
b) Type SW II (the wiper blade axis is operated from the side through a hole in the sight glass fitting by means of a
flexible shaft) – for higher pressure
Combination with a spray facility is also possible.
Lumiglas Ex-class motor drive
• General operating conditions:
