1. Instrument features SXF integrated programmable box-type electric furnace first solves the problem of large temperature fluctuations in ordinary high-temperature furnaces. The integrated production, easy to use and install, make the temperature control of the electric furnace more accurate and more automated. The intelligent control system absolutely guarantees the temperature control accuracy of the instrument. The control system adopts LTDE technology programmable intelligent instrument. It has the function of up to 30 heating programs, and can modify the slope and PID function. Automatic time temperature control system can accurately control the temperature, constant temperature time and automatically shut down. Second, the instrument uses the operation panel function
SET: Function key OUT: Output indication PV window: Measured value SV window: Set value ALM1: Upper limit alarm ALM2: Lower limit alarm <: Shift key ∨: Minus key ∧: Plus key AT (AL): Auto tuning
Common operation method: turn on the power and press the ↑ key for two seconds to cause STOP in the SV window. Setting procedure: Press ↠key PV to display C01. Press ↠↑ ↓ to set the desired temperature. Press SET, PV displays t01. Press ↠↑ ↓ to set -1. Wait until you return to the menu (SV displays STOP). Press the ↓ key for two seconds, SV displays RUN. At this time, the PV will show temperature rise. The SV window HOLD and the set temperature are displayed alternately. For example: if you want the instrument to maintain automatic constant temperature for a long time at 600 ℃, press the ↠key C01 = 600, press the SET key t01 = -1, wait until the SV returns to STOP, then press the ↓ key. When SV shows RUN, the instrument starts to work. Operation method of timer function: Turn on the power and press the ↑ key for two seconds to make the PV display STOP (pause). Press ↠key PV to display CO1, press ↠↑ ↓ to set the initial temperature 50 (start temperature should be higher than room temperature), press SET key, PV displays t01. Press ↠↑ ↓ to set the time from the initial temperature to the actual temperature required (the time should be longer than short). Press SET key PV displays C02. Press ↠↑ ↓ to set the temperature required for work, press SET key PV to display t02, press ↠↑ ↓ to set the required constant temperature time, press SET key PV to display C03, press ↠↑ ↓ to set the required actual temperature (ie the same as C02 Temperature), press the SET key PV to display t03, press ↠↑ ↓ to set -121. Wait until you return to the menu (SV displays STOP). Press ↓
The key will start in two seconds. The PV window displays a temperature rise at this time. SV shows temperature rise or time operation. For example: a constant temperature of 400 ° C for 10 minutes. Press the ↠key once C01 = 50 (The starting temperature is a value slightly higher than the room temperature, such as 50 ℃.) Press the SET key once t01 = 20 (Generally, this period of heating time should not be too short, otherwise it will be easy to overshoot. ) Press the SET button once C02 = 400 (working temperature required) Press the SET button once t02 = 10 (constant temperature time) Press the SET button once C03 = 400 (working temperature) Press the SET button t03 = -121 Wait until SV displays STOP and then Press the ↓ key for two seconds and SV displays RUN to start. At this time, PV shows the actual temperature rise. SV displays set temperature rise or time operation. Programmable normal operation method: turn on the power and press the ↑ key for two seconds to cause STOP in the SV window. Setting steps: Press the ↠key, the upper row of PV displays C01, indicating the starting temperature that needs to be programmed, operate the ↠↑ ↓ key to make the lower row of SV reach the desired starting temperature. Press SET again, PV displays t01, indicating the time from the initial temperature to the next set temperature. Operate the ↠↑ ↓ key to make SV reach the required time. Press the SET button again, PV displays C02, indicating the initial temperature C01 just set. It took t01 time to reach the desired temperature. Press ↠↑ ↓ to make SV reach the desired temperature. (If constant temperature is required, set C01 and C02 to the same value), then press SET key, PV display t02 indicates the time setting from C02 to the next temperature, follow the previous steps ..., the last paragraph T parameter setting "-121" It can automatically shut down, up to 30 segments, and at the end of the segment, set the txx-121 setting, wait for the SV to return to STOP, and then press the ↓ key to make the display window appear RUN. The instrument automatically starts working according to the set program. The program is arranged in temperature-time-temperature format, which is defined as setting the temperature from the current segment. After the time set in the segment reaches a temperature, press the ↠key and C01 = 100 ℃ (the starting temperature of the program can also be set slightly greater than room temperature Any value) Press the SET button t01 = 3 0 minutes press the SET button C02 = 300 ℃ press the SET button t02 = 35 minutes press the SET button C03 = 500 ℃ press the SET button t03 = 40 minutes press the SET button C04 = Press SET at 500 ℃ t04 = Press SET at 30 minutes C05 = Press SET at 1000 ℃ t05 = Press SET at 25 minutes C06 = Press SET at 1000 ℃ T06 = Press SET at 20 minutes C07 = 800 Press the SET button at ℃ t07 = 25 minutes, press the SET button at once C08 = 800 ℃ Press the SET button at t08 = -121 (end of program operation) (see the attached page LTDE intelligent instrument manual) 4. Notes 1. The instrument casing must be valid Ground to ensure safe use. 2. The instrument should be placed in a well-ventilated indoor horizontal position, and flammable and explosive materials should not be placed around it. 3. An iron blade switch should be installed in the power supply line for this box. Please check the electrical performance of the box before the shell is grounded, and pay attention to whether there is a circuit break or leakage. This instrument has no explosion-proof devices , Do not put flammable and explosive materials to dry. 5. Faults and troubleshooting
