20 Introduction
Programmers ATR620 are the results of a wide experience with
applications for temperature and process control by Pixsys
(
www.pixsys.net
).
High configurability of both hardware and software resources
allows the installer to configure the controller assuring both user-
friendliness for the operator and at the same time the
programming of complex and accurate firing profiles.
To program a cycle means basically to enter couples of values
time /temperaure (setpoint) for each segment of the cycle. Each
controller can be connected to one or two sensors; the output
options include relays and SSR control. Other resources are
available for the management of alarms, auxiliary and digital
commands. Possibility to integrate the unit into supervisory
systems or communication networks is assured by RS485 and
protocol Modbus-RTU with Master/Slave modality.
Memory card allows to quickly copy parameters and cycle data,
keeping record of the different configurations.
**Chapters 26.1 and 27.1 specifically focus on the operating
instructions for the users.
