Frese ELCO-100 Local Controller Quick Guide
This quick guide from Frese describes setting up the standalone ELCO-100 local controller. It shows the back-terminal wiring for a 3-wire PT100 sensor and for a 4–20 mA current-loop transmitter (0 to 100 °C) with a 24 VDC power supply, and identifies the front keys used to move through the menus.
The guide is built around worked menu examples: setting the analog input to 4…20 mA or to a 3-wire RTD probe with Pt100 linearization, selecting a 3-point step or continuous control type, setting the analog output to 4…20 mA, choosing control direction for heating or cooling, changing the PI controller parameters (Xp1, Tn1 and actuator time TT), and setting the serial interface address, baud rate and data format. A closing table lists 90° running times for 3-point actuators, followed by Frese office contact details.
Covers: Application example 1: Set analog Input type: 4…20mA · Application example 2: Set analog Input type: 3w RTD temp. probe · Application example 3: Set control type · Application example 4: Set analog output: 4…20mA · Application example 5: Setup control for heating/cooling applications · Application example 6: Change PI-controller parameters
