Instructions for use with the MICONT 1010 controller

Turn on the control unit. After turning on the power, a red “LOAD” appears on the digital display for several seconds. Wait until it disappears (the countdown of the controller’s load will occur) and two rows of red and green digits will appear in its place. The red indicator displays the actual temperature in the furnace chamber, the green indicator indicates the set heating temperature. Both temperatures are displayed with an accuracy of a tenth of a degree after the decimal point, if their value is less than 1000ºС, with large values - with an accuracy of 1ºС. Under the board is the inscription “Stages” and ten yellow LED indicators, numbered from 1 to 10, which make up the workflow schedule. Each of the stages is defined by the terms “TEMPERATURE” and two sections: “TIME OF ACHIEVEMENT” and “TIME OF HOLD”. There are only ten stages. To the left of a number of indicators is the ◄ button, and to the right is the ► button. By pressing these buttons we switch the stage number, the parameters of which will be displayed in green on the digital indicator. To the right of the board are the buttons “TEMPERATURE”, “ACHIEVEMENT TIME” and “HOLD TIME”, to the left of each there is an LED indicator. To display the temperature that you want to reach, press the TEMPERATURE button, to display the time of achievement - “REACH TIME”, and to display the retention time - “HOLD TIME”. When you press any of the above three buttons, the corresponding LED indicator will turn green, and the corresponding value will be displayed on the scoreboard in green numbers. The temperature is displayed in the format described above, the time is displayed in the format HH.MM (Hours Hours. Minutes Minutes).

Consider a graphing example. Briefly pressing the buttons "◄" or "►" select the first stage (yellow LED indicator with number 1). To the right of the scoreboard, press the "TEMPERATURE" button. The display will show a temperature of 850º (tuning value). Suppose we decide to change it to 830º. To do this, use the “▼” button, pressing and holding it, reduce the value to 830. If we “skipped” the desired value, then use the “▲” button. In the process of changing the temperature, its value displayed in green numbers will flicker, and the LED to the left of the TEMPERATURE button will change color from green to red, which indicates a change in value. Having received the necessary value, it must be fixed. To do this, press the “ENTER” button or the “TEMPERATURE” button. The numbers on the display will stop blinking, the “TEMPERATURE” indicator will turn green again.

Now let’s decide for what “ACHIEVEMENT TIME” the temperature should rise to 830ºС. Let it be 40 minutes. Press the button “TIME TO ACHIEVE”. 1.00, that is 1 hour 00 minutes (tuning value) is displayed on the scoreboard in green numbers. To change this value, use the ▼ button to decrease the value to 0.40 minutes. During the change, the value on the green indicator will flash, and the “ACHIEVEMENT TIME” LED will turn red. We confirm what has been achieved by briefly pressing the “ENTER” button or the “ACHIEVEMENT TIME” button.

Next, we determine which “HOLD TIME” we need the set temperature. Press the button “HOLD TIME”. 1.00 hours are displayed on the scoreboard in green numbers. If we want to work with this temperature all day, we increase the retention time in the above way up to 8.00 hours. For correct operation of the furnace in this mode, all other (subsequent) sections of the graph must correspond to zero values.

So, we have compiled one program, consisting of one stage. Now it must be saved. To do this, press the "PROGRAM" button. On the green indicator appears the inscription PR.01 (program No. 1). Next, press the “PROGRAM” button again and hold it until digital values appear instead of “PR.01”.



To compile programs with other numbers (PR.02 - PR.10) you must:

  1. By pressing the “PROGRAM” button, get the indication “PR.XX”. Use the “◄” and “►” buttons to select the program number and confirm it with the “ENTER” button. (If the new program does not involve major changes from the previous one (the programs are similar), use the transfer function of the previous program. To do this, instead of pressing the “ENTER” button, press the “PROGRAM” button.)

  2. Enter the required values for the steps in this program.

3. Press the “PROGRAM” button again and hold it until digital values appear instead of “PR.XX”.

Before starting the furnace, make sure which program number will be worked out. If, when turning over, the set program number flickers, before starting press the “ENTER” button and check the set values of this number. It makes sense to write the values of various programs in a separate log for reconciliation.

To start the oven, press the “START / STOP” button and hold it for 2-3 seconds until the red “Operation” LED lights up above the digital display.

After a few seconds, the relay for switching on the heating elements starts to work, and at the same time, the K1 LED indicator. The stove will start to heat up. The achievement of the set temperatures is always associated with a certain deviation, depending on many circumstances. Having completed the set program, the heating will stop and the stove will start to cool. If we want to stop the oven earlier, then press the "START / STOP" button and hold it until the "Work" LED goes out. Do not turn off the oven by simply turning the toggle switch. In the event of a power outage during operation, the oven is turned off. To continue the process, you must restart it. The next time the oven is turned on, it runs the last set program, if necessary, check the number of the installed program again by pressing the “PROGRAM” button and confirming with the “ENTER” button.

When working in the single-shelf heating-hold mode, it makes sense to set the achievement time to 3 minutes, since if you need to change the temperature, you will first have to stop heating by pressing the "START / STOP" button, and after the change, restart the furnace. If the time of achievement is large (say, 20 minutes), then raising the temperature, for example, from 830 º to 840 º, the furnace controller will produce in 20 minutes, and when this value is determined in 3 minutes, the speed of temperature setting will be limited only by power heating element.

When compiling a complex (multi-stage) schedule, it must be taken into account that the furnace cannot heat up very quickly and cool down very quickly.

The actual correspondence of the set and executable parameters can be monitored and further corrected if, during operation, the “TEMPERATURE”, “ACHIEVEMENT TIME”, and “HOLD TIME” buttons are additionally pressed. When pressed, the green indicator will show those values that have been calculated by the controller at a given moment in time for this parameter. To exit this mode, press the corresponding button again. Using this function, you can, for example, create a more accurate schedule for calcining flasks, depending on the load on the furnace. For example, if a large difference between the calculated and the true temperature is observed in the “ACHIEVEMENT TIME” section, it can be converted to equalize the readings in 2 stages.


The electric control circuit of the furnace consists of the controller itself, a temperature sensor (thermocouple), an actuator (solid state relay) and a heating element. If you encounter any problems in the operation of the furnace, they must be considered, focusing on this bunch.


* When the unit is turned on, the controller screen does not light.

Reason: The fuse has blown. Perhaps due to a surge in voltage. In this case, a breakdown of the relay for permanent closure and uncontrolled heating of the furnace, up to the destruction of the heating elements, is possible, in this case, heating can occur even without the controller screen glowing. The surge can be a consequence of the subsidence of organic particles on the inner surface of the spirals, which occurs when the flasks are calcined without first melting the wax. For MITERM furnaces, preliminary waxing outside the furnace is necessary.

Replacing the fuse, check if heating has started without starting the program. If this is the case, unplug the oven (unplug it) and contact MICROINSTRUMENT for repair. Note: when you turn on the controller in the first 2-3 minutes, room temperature readings may increase by 3-5 degrees, this is due to the stabilization of the electronic circuit.

* If the thermocouple burns out or the contacts of its connection with the controller (top connector) slip away, the inscription “no dt” is displayed in red on the screen. In this case, the heating stops. You must turn off the oven, check the thermocouple contact, or replace it.

* After starting, the “K 1” lamp lights up, but the furnace does not heat up.

Reasons: 1) burnout of the wire to the heating element 2) burnout of the heating element 3) failure of the relay. In all cases, contact the MICROINSTRUMENT company.

* When you touch the stove with your hand, residual stress is felt.

Reason: the absence of a grounding wire in the socket, or its connection in the shield with a neutral wire. Residual voltage is almost always present in the furnace, and as it increases, work with the furnace should be stopped until the causes are clarified. Contact an electrician.

* The formation of microcracks on the heating elements.

Reason: this is most often associated with operation in extreme temperature conditions and excessive loading of the furnace. MITERM furnaces can operate in the “FULL” mode, when the power supply to the heating elements is continuous, however, it is not recommended to use this mode with a large load. In this case, “TIME OF ACHIEVEMENT” should be increased.

* Large run-out of temperature.

Reason: most often observed at temperatures below 700 ° C, it can also occur due to overload of the furnace with products or due to increased voltage in the network. The problem can be solved by lowering the set temperature by an amount selected by the user.

In the event of a power failure, the controller must be restarted, taking into account that the program will start working again (if necessary, correct the calcination process). The program can be launched from any stage.

It should be noted that the coordination of technological processes with the possibility of a furnace is a rather complex process that requires certain knowledge and experience.
