Description
Temperature controller
Intelligence dual row 4-LED diSplay
Operated with 4-key
Control method: On/off, automatic regulation
XMT*7000 series temperature controller are intelligence dual row 4-LED display for displaying the measured value and set value respectively. The temperature meter are operated with 4-keys, allowing an easy inputting. The available control methods include on/off, 2-on/off, PID and automatic regulating and setting controls.
I.Product characteristic
The core of the product adopts the up-to-date microrocessor chip.
Red and green double-bank nixie tube display the measured value and setting value.
Easy operation in the four/three keys, & fast setting in the parameter.
Control in high precision's PID intelligent and two or three bit location check program.
Upper-bank display the measured value, & bottom-bank display the setting value under normal working conditions.

| Code | Description | Setting range | Instruction | Remarks |
| SP | Setting control point | Whole range | ºC or 1 defined unit | _ |
| AL1 | Alarm 1 | Whole range | ºC or 1 defined unit | |
| AL2 | Alarm 2 | Whole range | ºC or 1 defined unit | |
| SC | Measurement update | -20.0 to 20.0 | Measuring value can be modified through
increasing or decreasing this data.
Note: It may be cause inaccurate racy of measuring value when you use this function . Please use the function carefully according to your situation. | 0 |
| P | Proportional band | 0 to 9999 | When the P↑,the proportion and differential function↑; if the P↓,the proportion and differential function↓. When P=0,the meter is ON/OFF control | 100 |
| I | Integration time | 0 to 3000s | It's mainly used to adjust the static difference. To increase it, the static difference will be reduced, but when it is too high, the static difference will drift instability. | 500 |
| d | Differential time | 0 to 2000s | When the I↓,the calculus function↑;
I↑the calculus function↓.
When I=0, no calculus function, it is PD adjustment instrument | 100 |
| t | Control period | 1 to 120s | When the d↓,the proportion and calculus function↑; if d↑,the proportion and calculus function↓,but the differential function↑.
When d≤t, it has no differential function | 20 |
| Hy | Deadband | 0.1to 50.0 | ON/OFF control only | 1.0 |
| At | Auto-man | 0 to 1 | 0- Close auto-man function
1- Open auto-man function | 0 |
| Lock | Key lock | 0 to 1 | 0- All the parameter can rework
1- Only SP value can rework
>1 All the parameter can not rework | 0 |
