5.1 عرض أكثرview
The MC701 features a dual display:
- PV (Process Value): Displays the current measured temperature.
- SV (Set Value): Displays the desired target temperature.
أضواء المؤشر:
- OUT: Indicates output status (heating/cooling).
- AT: Auto-tuning indicator.
- ALM1, ALM2: Alarm indicators.
5.2 وظائف الأزرار
- SET: Enters parameter setting mode or confirms a setting.
- < (R/S): Shifts cursor during setting, or resets alarm.
- V (Down Arrow): Decreases value during setting.
- ^ (Up Arrow): Increases value during setting.
5.3 ضبط درجة الحرارة المستهدفة (SV)
- اضغط على تعيين اضغط على الزر مرة واحدة. ستبدأ شاشة SV بالوميض.
- استخدم ^ و V أزرار لضبط درجة الحرارة المطلوبة.
- استخدم < button to shift the cursor for faster adjustment.
- يضعط تعيين again to confirm the new SV and exit the setting mode.
5.4 إعدادات المعلمات المتقدمة
To access advanced parameters (e.g., PID parameters, alarm settings, input type, temperature unit), press and hold the تعيين button for several seconds until the first parameter code appears on the PV display.
- يستخدم ^ و V للتنقل بين المعايير.
- يضعط تعيين ل view or edit a parameter's value.
- اضبط القيمة باستخدام ^, V، و <.
- يضعط تعيين to save the value and return to the parameter list.
- To exit advanced settings, press and hold تعيين again, or wait for a timeout.
6. الصيانة
Regular maintenance ensures the longevity and optimal performance of your MC701 controller.
- Cleaning: Wipe the display and casinامسح بقطعة قماش ناعمة وجافة. لا تستخدم المنظفات الكاشطة أو المذيبات.
- Ventilation: Ensure the ventilation slots on the sides of the unit are not obstructed to prevent overheating.

7. استكشاف الأخطاء وإصلاحها
| مشكلة | السبب المحتمل | حل |
|---|---|---|
| Display shows "HHHH" or "LLLL" | Sensor open circuit or short circuit; temperature exceeds range. | Check sensor wiring and connection. Verify sensor type matches setting. Ensure temperature is within range. |
| وحدة التحكم لا تعمل في التدفئة/التبريد | Output wiring incorrect; SV not set correctly; PID parameters need tuning. | Check output wiring (SSR/Relay). Confirm SV is set to desired temperature. Perform auto-tuning if necessary. |
| تتقلب درجة الحرارة بشكل كبير | PID parameters not optimized; sensor placement. | Perform auto-tuning. Ensure sensor is placed correctly and securely. |
| لا يوجد عرض/مشكلة في الطاقة | لا يوجد مصدر للطاقة، الأسلاك غير صحيحة. | Check power connections (terminals 8 & 9). Verify power source is active. |
