1 Introduction
1.1 Description
The controller series consists of four freely programmable instruments in different DIN
formats for controlling temperature, pressure and other process variables. The high-
contrast, multicolor LCD display for process value, setpoint and operator prompting
contains two four-digit 7-segment displays, two single-character 16-segment
displays, display of the active setpoints, six status indicators, and displays for the unit,
ramp function and manual operation.
Just four keys on the front panel are needed for operation, parameterization and
configuration. The instruments can be used as 2-state, 3-state, modulating or
continuous controllers. The controller software includes a program or ramp function,
parameter set changeover, autotuning (self-optimization), a math and logic module, as
well as 4 limit comparators.
Linearizations for the usual transducers are stored, and a customer-specific
linearization table can be programmed.
A setup program is available for user-friendly configuration from a PC.
An RS422/485 or a Profibus-DP interface can be used to integrate the instrument into
a data network.
The electrical connection is made at the back of the instrument, via screw terminals.
