2 Introduction

2.1 Overview

Controller MKA 120 has been developed for use in

cooking, baking and boiler systems. It is infinitely

variable and can be easily adapted for a range of

applications.

The controller has 2 temperature measurement inputs

and 3 potential-free output relays. The controller

regulates the temperature through heating or cooling.

Shut-down conditions can be either the operating time

and/or the core temperature. Delta T cooking is also

possible with the appropriate encoding.

The assignment of relays to the processes is infinitely

variable. Relays can be assigned as leading, lagging,

switch-on as well as switch-off delayed or pulsing relays.

An optional serial interface allows for data transfers

between the controller MKA120 and a PC. The controller

can be programmed via a PC with the installed aditec service program. The connection is made via

a mini USB or optionally via LAN or a serial interface RS485, respectively.

The visualisation program aditec „VisuNet“ allows you to connect one or several controllers to a

superordinate program surveillance. This enables you to log temperature profiles, treatment types etc.

and ensures comprehensive quality control of the treated products in compliance with HACCP and IFS

(ISO 9000). Furthermore the tele-control and remote maintenance system aditec Control lets you

monitor and operate the VisuNet program from anywhere, thereby allowing you to directly influence

the system.

2.2 Controller characteristics

⚫Number of programs and steps can be pre-programmed, max.99 steps in total, 1 manual program.

⚫Straight forward, systematic setting of the configuration data.

⚫Programmabel processes

⚫3 potential-free relay outputs can be programmed

⚫2 x galvanically isolated analogue inputs which can be programmed as: Pt100 (for 3 wire connection

with automatic power compensation), all standardised thermo-elements incomplince with DIN EN

60584 among others Type K: NiCr-Ni. Pt100 or as digital inputs

⚫Ethernet LAN for connection to a PC or connection via an expansion card (ZSL)

⚫RS485 for connection to a PC via an expansion card (ZS4)

⚫Mini USB connection (USB serial port for a firmware update)

⚫4 x LED buttons (red) for status displays

⚫OLED-display with 128x64 pixel resolution and 16 grey scales

⚫Robust stainless steel housing (1.4016)

⚫Network for the visualisation and recording in accordance with HACCP is possible with aditec-

VisuNet

⚫Programmable nominal limit values

⚫Program memory is retained during a power cut

⚫Programs interrupted by a power cut will be resumed at the point (can be defined) where they were

interrupted once power is restored.

⚫Process runtime from 00h : 01min to 99h : 59min or continuous operation

⚫Pre-set time (start time) can be pre-set via real time/date

⚫Sensor breaks (interruption or short circuit) are shown

⚫5 limit value alarms

4 Control elements

4.1 Entering values (Edit box)

Values are entered by using the arrow

buttons.

How to enter values:

▪Cursor is flashing in the position ‚far right’: „00“.

▪When you are making an entry, the cursor is at first in the position ‚far right: „00“. Use the

button to increase the value and the button to reduce the value. The numbers will

automatically shift to the left „10“. The value of the entry is limited by the limit value range.

▪When you press the arrow button ‚left’, you can change the individual digits.

Entering negative values:

Certain nominal values can be negative numbers (e.g. temperature values). In order

to enter a negative value you have to press the arrow button „down“ until you go past

value 0 then a minus („ - „) sign will appear in front of the numbers.

Entering positive values:

When you want to change a negative number into a positive one you can either use

the arrow buttons to position the cursor on the „-“ sign and overwrite it with a „+“ with

the arrow button „up“ or you can enter a value higher than „0“.

Hint

Scrolling characters:

Use the arrow buttons „up“ / „down“ (keep pressed) to scroll a character.

4.2 General text entry (Edit box)

How to enter text:

▪Cursor is flashing in the first position: „_“.

▪When you are making an entry the cursor is at first in the position „_“. Use the button

to scroll the characters (number/letter/ special character) up, or the button to scrol

them down. Us the arrow buttons ‚left’ or ‚right‘to change the indiidual digits. In this way

you can take the cursor to any position in the entry box.

Characters can only be entered in the position that is flashing. Press the relevant button „up“

or „down“ until the required character appears.

The first character is a blank.

4.2.2 Deleting a character:

If you want to overwrite a character use the arrow buttons ‚left’ and ‚right’ to take the cursor to the

required position and entert he new character in this position.

If you want to delete a character, take the cursor to the right of the position you want to delete.

Press the „Temp“ button to backspace and the character is deleted.

Hint

Scrolling characters:

Use the arrow buttons „up“ / „down“ (keep pressed) to scroll a character.

4.3 Buttons

The button allows the user to trigger an assigned function.

When the button is focussed (frame around the info text) it can be activated by

using the ‚Line‘ button. If several buttons exist, you can use the arrow buttons “up”

or “down”, respectively, to focus the following or previous button.

4.4 Check boxes

Check boxes allow you to set e.g. a state. When a check box is focussed (frame

around the info text) you can change its state to selected (Relay 1) or not

selected (Relay 2,3) by using the ‚Line‘ button. If several check boxes exist you

can use the arrow buttons “up” or “down” respectively to focus the following or

previous check box.

4.5 List box

List boxes allow you to clearly display e.g. codes in a list. Use the arrow buttons “up”

and “down” to focus an entry (background = white, writing = black) and the ‚Line‘

button to select it. The status bar gives you only an overview. The scroll bar is

automatically moved when the last item of the visible segment is focussed with the

arrow buttons

4.6 Drop box

A drop box is used to select one item from a shown list of items.

Initially, the previously selected item is shown. Use the arrow

buttons “up” or “down” respectively to focus the following or

previous item. When you press the ‚Start‘ button, a list of all

available items on the list will flick open and you can use the

arrow buttons “up” or “down” respectively to focus the following

or previous item. (background = grey, writing = white). The

currently selected item is shown on the menu tab. Use the

‚Time‘ button to shut the drop box and the newly chosen item is

automatically selected.
