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.
