1 Introduction

1.1 Overview

Processor MIC 990, with user-friendly touch panel, 7“ TFT display with resistive touch technology,

several interfaces and a housing of standard industrial quality, are designed for use in deck ovens.

In its standard version the controller is equipped with

4 Pt100 temperature inputs and

2 inputs which can be converted to Pt100 and current 4-20mA / voltage 0-10V or thermocouples

(compliant with DIN EN 60584).

The following interfaces allow communication: LAN/Ethernet and USB Serial Port.

In order to adapt the controller for specific purposes each control loop can be used as a 2-point

controller, XP controller or with PID behaviour.

MIC 990:

The standard version has 16 relay outputs

(12 normally open contact and 4 changeover contacts).

1.4 Entering numerical values

A numerical pad is used to enter numerical values. It will be displayed when

you have to enter values.

- Deleting the value in an entry box

- Changing the leading sign of a value

- Closing the keypad. Changes made to the nominal value

are not saved.

- De-activating a nominal value

- Saving an entered value

Be aware

The controller also allows you to enter negative temperature values:

-In order to pre-program negative nominal values in a step, the installation manufacturer

has to pre-program negative nominal value limits for chamber and core.

- „0“ can be entered as a nominal value. The nominal value „Off“ is shown for chamber

and core when a new program step is pre-programmed. . This means: the nominal value

is deactivated. As soon as a value is entered (even if it is „0“) the nominal value counts

as activated. If you want to deactivate the nominal value later in the step, press

the „Off“ button.

1.4.1 Screen lock

All display functions are blocked when you press the „Enter“ button during 3 sec. On the lower margin

of the display appears “Lock”. To deactivate the look, press the “Enter” button for 5 sec.

Please not

The program processing is independent of screen lock. If the screen lock is activated in

operating mode the program will continue.

The activated screen lock has no influence on the communication with VisuNet or Service

program. If the screen lock is activated you can start and stop programs via VisuNet.

This function is helpful when the unit is cleaned up.
