Fourth, the use and adjustment

— 5 —

1. Check whether the scale number of the instrument is the same as that of the temperature sensing element;

2. The instrument equipped with thermocouple may not be connected with15Ω external resistor, which will not affect the accuracy. If the distance is far away, the thermocouple and the instrument should be connected with corresponding compensation lines, and the polarity cannot be reversed, so as not to affect the accuracy; The installation position of the sensor should correctly and timely reflect the temperature rise and fall of the measured object; If it is found that the instrument is abnormal, check whether the sensor connection is open (the instrument has disconnection protection function); Instruments equipped with thermal resistors are generally not connected with three 5 Ω external resistors, but the specifications and lengths of the three connecting wires of thermal resistors should be the same. If the lead is long, it is recommended to use an external resistor, and this should be stated when ordering.

3. Insert the instrument into the mounting hole, and properly tighten the mounting screws on the upper and lower sides. Be careful not to tighten the screws too tightly to avoid damaging the shell.

4.XmZ, XMZA and XMZD models: Connect the power supply and temperature sensing element, and display the measured temperature value without adjustment.

5. xmt–101,102, xmta–2001,2002, xmtd–2001,2002, xmt–800/kloc-0. At this time, the digital display shows the actual temperature value of the measured object. When the actual value is lower than the set value, the green light is on, and the total low-pass and total high-break of the output relay are turned on. When the actual value reaches or exceeds the set value, the red light is on, and the total Qualcomm and the total low break of the output relay are turned on. For the instrument set with dip switch, just dial the dip switch to the required temperature value after wiring, and the control state is the same as above.

6.xmt- 12 1 (female), 122 (female), xmta-220 1 (female), 2202 (female), xmtd-220 1 (. Turn the switch to the "upper limit setting" position and turn the corresponding upper limit setting knob, and the required upper limit temperature value will be displayed at this time; Then turn the switch to the "measurement" position, and the digital display shows the actual temperature value of the measured object. When the actual value is lower than the lower limit set value, the green light is on, and the upper limit relay is always low on and high off; When the actual value reaches or exceeds the lower limit set value but is still lower than the upper limit set value, the green light and red light are all turned off, the lower limit relay is always low-cut and Qualcomm, and the upper limit relay is always low-cut and high-cut; When the actual value reaches or exceeds the upper limit set value, the red light is on, and the upper and lower limit relays here are always low-off and always Qualcomm. In general, the output of the lower limit relay can be used for auxiliary heating control, the upper limit relay can be used for heating control, or the output of the lower limit relay can be used for temperature control, and the output of the upper limit relay can be used for over-temperature alarm. For instruments with suffix "f", the temperature required for the upper limit must be adjusted to be higher than the lower limit.

Temperature value. When the actual value is lower than the lower limit, the green light is on, and the relay is always low and hot; When the actual value is higher than the lower limit and lower than the upper limit, it is still all low-pass and the temperature rises; When the actual value is higher than the upper limit, the red light is on, the relay is always Qualcomm, always low, and the heating is stopped. Only when the actual value is lower than the lower limit, the green light is on and always low, and the whole process is repeated. There is only one relay output, which is convenient to connect with the load.

7.xmt– 13 1， 132，xmta–230 1，2302，xmtd–230 1，2302，xmt–830 1，8302。 When the actual temperature does not enter the proportional band, the green light is on, the relay is always low on and high off, and the load is hot; When entering the proportional band, the relay starts to switch regularly, and the traffic lights change periodically. The higher the temperature, the shorter the total low-pass time, and vice versa. Change the temperature of the instrument by changing the average heating power of the load, such as the instrument with overrun alarm function, such as xmta–2311,23 12, xmta-231,23 12. Other usage methods are the same as XMT- 10 1 and 102.
