Introduction
Thank you for choosing a Pixsys controller.
With the DRR227 Pixsys model Pixsys makes available in a single device multiple
options related to sensor input and actuators command in addition to the extended
power range 24..230 Vac/Vdc. With the various selectable sensors and the output con-
gurable as relay or SSR command, the user or retailer can reduce stock by rationalising
investment and device availability
1 Safety guide lines
Read carefully the safety guidelines and programming instructions contained in
this manual before using/connecting the device. Disconnect power supply before
proceeding to hardware settings or electrical wirings. Only qualied personnel should
be allowed to use the device and/or service it and in accordance to technical data and
environmental conditions listed in this manual. Do not dispose electric tools together
with household waste material. In observance European Directive 2002/96/EC on
waste electrical and electronic equipment and its implementation in accordance with
national law, electric tools that have reached the end of their life must be collected
separately and returned to an environmentally compatible recycling facility.
