Conventional power frequency systems (24V/110V/230V power supply)
Circuits with frequent start-stop and demand for rapid safety cut-off
5.4 السيناريوهات غير الموصى بها (احتياطات)
- Explosion-proof Areas: لا توجد شهادة مقاومة للانفجار. Use dedicated PILZ explosion-proof safety relays for explosive workshops.
- Outdoor Exposure / High Humidity & Condensation: IP40 protection is insufficient; an additional protective enclosure is required.
- Severe Electromagnetic Interference: (Near high-frequency welders or large inverters) Shielding measures and independent earthing are necessary.
- Overload Operation: Contact current must not exceed 6A. Add intermediate contactors for high-power loads.
- Ambient Temperature above 55℃: Will shorten service life of safety contacts and cause false tripping.
5.5 حالات التطبيق النموذجية
قضية 1: Safety Protection for Vertical Machining Center
إعدادات: 772140 (24الخامس التيار المتناوب/تيار مستمر) + Safety gate switch + Emergency stop button
وظيفة: Opening the equipment guard gate → Safety relay actuates → Cuts off power to spindle and feed motors; Automatic reset and restart after gate closure.
فوائد: Complies with machine safety standards and prevents personnel from entering mechanical hazardous zones.
قضية 2: Food Flow Wrapper
إعدادات: 772143 (230الخامس و) + Safety light curtain
وظيفة: If operators accidentally reach into the operating area → Light curtain triggers → Relay cuts off main drive power.
فوائد: IP40 rating adapts to slight water vapor in workshops; automatic reset ensures continuous production.
- دليل اختيار النموذج
القواعد المرجعية السريعة
- The three part numbers differ only in coil voltage, with identical appearance, contacts and functions:
772140 = 24V AC/DC (عالمي, first choice)
772142 = 110V AC (For Japanese-style and overseas equipment)
772143 = 230V AC (For domestic 220V mains power)
- PNOZ X2 = 2 سلامة لا اتصالات + إعادة التعيين التلقائي
- Selection Priority: Confirm control cabinet supply voltage first, then verify reset mode (automatic / manual).
- استكشاف الأخطاء وإصلاحها
| ظاهرة الخلل | Probable Cause | حل |
| مؤشر الطاقة مطفأ, no response | Broken coil wiring, loose terminals, power failure | قياس جهد الإدخال, tighten screws, check upstream circuit breakers and fuses |
| التعثر الكاذب المتكرر | Loose wiring in safety circuit, electromagnetic interference, poor contact of gate switches | Re-crimp terminals, route cables away from power lines, replace worn safety switches |
| Safety circuit normal but relay fails to energize | Aged internal contacts, damaged coil, end of service life | Replace with an identical safety relay (Safety components are not repairable) |
| Output contacts cannot open (welded) | Long-term overload, load short circuit, frequent high-current surges | استبدل التتابع; add intermediate contactors for current division; never exceed 6A rated current |
| Abnormal reset, failed automatic restart | Incomplete closure of safety circuit, line short to ground | Check continuity of the entire safety circuit and eliminate short circuits |
Safety Regulation: Faulty safety relays are prohibited from disassembly and repair. The complete unit must be replaced.
