1. Set temperature: Press the SET button to set or view the temperature set point. Press the SET button at the beginning of the digital tube character flashing, indicating that the appearance has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, press and hold the △ key or ▽ key The data will change rapidly, press the SET key again and the appearance returns to the normal operating condition and the temperature is set.
2. Return control (XMT201-C): Press the SET button for 3 seconds to enter the inner layer parameter setting status. The first presented and flashing parameter is C00, that is, the return difference control parameter should be carefully adjusted, the appearance of the control heating output value to the set value, when the temperature falls to the set value to reduce the difference value, and then start heating, the output (relay) is not active in the return scale, so that the relay action number can be reduced to extend the life of the relay. For example, if the setting value is 80.0°C and the return difference is 0.5, the relay is released when the surface control is heated to 80.0°C, and the relay is engaged when the temperature drops to 80.0°C-0.5°C=79.5°C. The larger the return difference, the fewer the relay actions, and the excessive return difference will reduce the control accuracy. After adjusting the differential parameters, press the SET button for 3 seconds to return to the normal operating condition.
3. Early Setting (XMT201-E): Press the SET button for 3 seconds to enter the inner layer parameter setting. The first parameter that is presented and flashed is E00, that is, the early amount of heating abort, the early amount parameter should be carefully adjusted, in order to reduce the temperature overshoot, the heating output will be cut off early when the surface is manipulated. When the temperature drops below the early amount, the heat is started, and the output (relay) is not operated within the set value and the early amount scale, so that the number of relay actions can be reduced to extend the life of the relay. For example, if the setting value is 50.0°C and the early amount is 0.5, the relay is released when the surface control is heated to 49.5.0°C, and the relay is engaged again when the temperature drops to 50.0°C-0.5°C=49.5°C. The larger the early amount, the fewer the relay actions, and the excessive early amount will reduce the control accuracy. After adjusting the early amount parameters, press the SET button for 3 seconds to return to the normal operation status
4. Time share setting (XMT201-P): Press the SET button for 3 seconds to enter the inner layer parameter setting status. E: is the share band offset, and the E parameter allows the practice control point to be translated. Even if the center of the moment share shifts, the E-value can be positive or negative depending on the heating system. P: is the share band, that is, the share manipulation value, in order to facilitate understanding together and in order to make the share with more room for expression, the share band of this table is a unilateral share band, that is, the practical share band is 2 times the P value. Focusing on the practice control point, from bottom to top, the output heating share is evenly distributed from 0% to 100% within the scale of P value. T: For the heating output cycle cycle, that is, the relay operation cycle cycle, the T value is small and the control effect is good, but the T value is too small The relay will reduce the life due to frequent operation. Generally, the T value is taken for 20-60 seconds. For example, if P is set to 4.0 (the actual band is 8.0), the temperature is set to 60.0 degrees, and E is set to 2.0, then the practice control point is 58.0 degrees, and when the temperature reaches 54.0 degrees, the appearance will enter the share band control state.
5. Intelligent control parameter setting (XMT201-D): Press the SET button for 3 seconds to enter the inner parameter setting status on the outer surface. E: This parameter is the early amount of heating stop when P = 0, when P is not equal to 0, it looks like an intelligent PID operation method, and when P is not equal to 0, the E parameter is meaningless. P: is the share band, that is, the share control value, the P-value is distributed on both sides of the set point with the set value as the center of the outer table, and the PID method is used in the inner and outer tables of the P value scale. T: For the heating output cycle cycle, that is, the relay operation cycle cycle, the T value is small and the control effect is good, but the T value is too small The relay will reduce the life due to frequent operation. Generally, the T value is taken for 20-60 seconds. To simplify the operation, the integration time (I) and differentiation time (D) of the appearance are planned as hidden parameters, and their default values are: I=180, D=45
6. Correction of errors: The displayed values can be corrected when acknowledging that the values displayed on the surface are not correct measurements. Press the SET button for 3 seconds to enter the inner menu on the surface, the first parameter presented and flashed is E00, that is, the early amount, and then press the SET button again to present and flash the parameter that is the error correction parameter, and this parameter can be corrected with the △ or ▽ key. The scale of the error correction is -9.9°C to +9.9°C, and after the correction is completed, press the SET button to exit. The correction value of the appearance is 0.0 when leaving the factory, and it is necessary to avoid correcting the correct appearance to incorrect when using.
