What is the condition of alarm in advance when the box furnace is heating

Recently, some of our customers reported that when the box furnace was heating, it started to alarm before it reached the set temperature. Our engineers took corresponding measures to solve this problem. Please follow the following steps to check the cause of the problem.

First, we should first look at the temperature control meter. Here, its setting value must be zero. Only zero is normal.

Second, check the setting value to see if it is set incorrectly. That is to say, look at the SV data on the box electric furnace.

Third, check the set upper limit alarm data to see how much it is. Generally, the alarm data slightly exceeds our set temperature, that is, after the correct digital temperature of the box type electric furnace plus the upper limit temperature, the total temperature slightly exceeds our set temperature.

In general, we can start from two points: first, check the probe, that is, the thermocouple; Second, check whether the temperature controller of the box electric furnace works normally. Check according to the above method. If the problem is still not solved, please call us. We will send engineers to solve various problems for you.
