10.3.1 Assignment of the analogue inputs
Analogue inputs Pt1000 (Pt1..15)
DANGER
Warning about dangerous electrical voltage! Danger to life - Danger of electric shock!
If supply
voltage is connected to the analogue inputs, there is a risk of personal injury as the analogue inputs
are not galvanically isolated from other system components (e.g. pressure transmitters). Furthermore
this will destroy the controller!

ATTENTION
Malfunction due to interference!
All supply lines from and to the controller (with the exception of the
230 V power supply and signal lines) must be shielded (cable type LiYCY)! This particularly applies for
the analogue inputs and outputs (e.g. sensor supply lines). As a general rule, care should be taken to
ensure that signal cables and cables carrying mains voltage are routed in separate cable channels The
following must also be observed for the installation of the analogue inputs:
Correct sensor positioning
Correct fixing of the sensors by using metal clamps and thermally conductive paste
Insulation of the sensors (e.g. protect sensors against direct exposure to sunlight)
