Xta-7000 Temperature Controller Manual -
Hold the SET key for more than 3 seconds to enter the parameter configuration layer. This is where the XTA-7000 becomes powerful.
| Parameter | Name | Function | Typical Value |
| :--- | :--- | :--- | :--- |
| P | Proportional Band | Control sensitivity. Lower = faster response, higher = stable but slow. | 30.0 (start here) |
| I | Integral Time | Eliminates steady-state error. Lower = faster elimination (risk of oscillation). | 240 seconds |
| D | Derivative Time | Anticipates future error. Prevents overshoot. | 60 seconds |
| Ar | Anti-Reset Windup | Limits integral action when output saturates. | 1.0 |
| Sc | Sensor Correction | Offsets a faulty sensor reading. | 0.0 |
| At | Auto-tune Enable | 0=Off, 1=On (self-tune), 2=On with light overshoot. | 1 |
| AL1 | Alarm 1 Mode | 0=No alarm, 1=Absolute high, 2=Absolute low, 3=Deviation high/low. | 1 |
| HY | Hysteresis (for On/Off mode) | Deadband to prevent relay chattering. | 2.0 |
Red Flag Warning from Manual: Do not change P, I, and D manually unless you understand PID control. Always run Auto-tune first.
The XTA-7000 supports multiple alarm modes. Set the alarm type in the hidden AL-M menu (press both ◄ and ▼ for 5 seconds from the advanced menu). Common modes:
| Code | Alarm Mode | Action | |----------|-----------------------------------|--------------------------------------------------------------| | 0 | No alarm | Disabled | | 1 | High absolute alarm | Activates if PV > AL1 (e.g., over-temperature protection) | | 2 | Low absolute alarm | Activates if PV < AL1 | | 3 | Deviation high alarm (relative) | Activates if PV > SV + AL1 | | 4 | Deviation low alarm | Activates if PV < SV - AL1 | | 5 | Heater break alarm | Requires optional CT (current transformer) input |
Example: For a furnace that must not exceed 500°C, set AL1=500, AL-Mode=1. Connect AL1 relay to a master contactor. xta-7000 temperature controller manual
