Introduction
Thanks for choosing a Pixsys controller.
The DRR450 series integrates in a single device the main
elements of the control loop: reading of temperature
sensor, control output by SSR module, reading and control
of the current on the load by means of integrated current
transformer. Serial communication RS485 and ModbusRTU
protocol allow the connection to PC/HMI Panels for
supervisory functions/remote control.
A second output is available for alarm or management of
cooling systems for double PID action.
 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 qualied 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 implemen-
tation 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.

Although this controller has been designed to
resist noises in industrial environment, please
notice following safety guidelines:
· Separate control lines from the power wires
· Avoid the proximity of remote control switches, electro-
magnetic meters, powerful engines.
· Avoid the proximity of power groups, especially those with
phase control.

Automatic tuning is always active and analyses constantly the
dierence setpoint-process. If this dierence is greater than
the value selected on parameter 7
m.G.tu. (Max Gap Tune),
the DRR450 decides autonomously when to modify PID
parameters.
