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.
As a temperature controller TR
1
according to EN 14597 the devices are used in heat-
generating plants to control the temperature of liquids or gases (mode of action: 1B).
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, two autotuning (self-optimization) procedures, 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.
