ROUND UP CONTROL SYSTEMS + AUTOMATION
Automatic transfer switch controller for motorised switches
Control Applications is now marketing a new
ATS changeover system, the ELNet CO which
features an advanced, user-friendly, interface –
the signature of all ELNet products. As its name
suggests, this ATS controller is designed for
changeover between two power sources, inmost
cases: the electric utility and local generator.
Featuring a built-in voltmeter, it eliminates the
need for no-voltage and delay relays, selectors,
control relays and naturally volt-meters. Fea-
turing Alarm and Event History Logging of up
to 1 000 alarms/ events and full open protocol
communication, supportingModbus and BACnet
via a RS485 port it is the ultimate changeover
solution for BMS integration.
Other features include Double Interlock
Protection, preventing simultaneous activation
of both power systems, and a menu-driven
graphic display (320 x 240 mm). All operational
parameters are adjustable and as a bonus fea-
ture you may find Self-Check Mode, enabling
auto-confirmation of proper wiring installation.

Multifunctional display – speed, time, counter
Themultifunction display shows various measured values in industrial automa-
tion. It uses the principle of interval measurement to processes input pulses.
The scaling factor allows (rotational) speed and processing time, etc. to be
calculated, displayed and converted into an analogue signal.The unit can also
act as a counter or an industrial timer.
Five different operating modes, optional analogue and switching outputs
as well as the convenient display make the multifunctional evaluation system
fit for various applications in industrial automation.

Optical data transmission
The Leuze DDLS 500 optical data transmission photoelectric
sensor is so much more than an optical sensor.This innova-
tive sensing device offers many more features that make
it both efficient and simple to use. Through continuous
monitoring of the receiving level, the user can be alerted to
an impending failure in good time. Available from leading
sensor solutions supplier, Countapulse Controls, the Leuze
DDLS 500 enables the transparent, contact- and wear free
transmission of data over distances of up to 120metres in 100
Mbit/s real-time.This is achieved by using an invisible infrared
laser which communicates bi-directionally between devices.
The sensor is ideal for all applications where data needs to
be transmitted without cables, andmore importantly without
interference. It is favoured for applications where mechanical
systems are pushed to their technical limitations.
To permit fast visual control, the Leuze DDLS 500 has an
LED display that is clearly visible from a distance of 200
metres. All relevant information is precisely depicted on
the control panel.The device’s patented single hand adjust-
ment process and integrated
mounting plate with alignment
screws enables easy mounting
by just one person.This makes
it easy to install, and the aid of
an integrated laser alignment
and level facilitates rapid align-
ment, even over longer paths.
