1. INTRODUCTION
1.1 General description
μC
2
SE for process chiller is a compact electronic controller designed for the complete management of the process chiller with 1 refrigerating circuit:
it can control air-water and water-water machines. The controller has 5 digital inputs, 5 digital outputs, 4 analogue inputs and 1 analogue output.
It can be installed:
- individually;
- connected to the tLAN network with the EVD
4
driver to manage the electronic expansion valve;
- connected in tLAN network with inputs/outputs expansion board.
The PWM output can be converted using the following modules:
• CONV0/10A0: conversion from PWM output for SSR into a linear analogue signal 0...10 Vdc and 4...20 mA;
• CONONOFF0: conversion from PWM output for SSR into an On/Off output from relay.
Main functions
Briefly:
- control of: compressor, condenser fan, water pump for evaporator and/or condenser, anti-freeze heaters, alarm signal devices;
- regulation of the set-point on evaporator input probe (B1), evaporator output probe (B2) or differential (B1-B2);
- condenser fan/pump speed control;
- complete alarms management;
- elimination of storage vessel in event of low load;
- serial connection to the EVD
4
driver for control of the electronic expansion valve;
- serial connection to the I/O expansion board for:
1.
connection of devices (thermostats/pressure switches) to digital inputs of the I/O board;
2.
display of further warnings/alarms on the controller display;
3.
selection of the digital outputs to switch-over.

1.3 Accessories
I/O board (cod. MCH2000060)
The board, connected in tLAN network to the controller, has 5 digital inputs and 5 digital outputs. The
switch-over of every digital input can be associated to a determined alarm signal, shown on the controller
display and also to a switch-over on the selected digital output.
