🛠️ Installation & إرشادات الصيانة

1. Cone sealing design; sealing relies on cone-face compression, do not use PTFE tape. Torque must be strictly controlled at 30~50 Nm to avoid housing deformation
2. The probe must be fully immersed in the medium for accurate measurement; avoid only touching the pipe wall
3. IO-Link can rescale the 4~20mA range; parameters saved after power cycle. Wire-break diagnostic (fault signal below 4mA) available
4. Washdown: High-pressure spray permitted (IP69K). Avoid heavy mechanical impact on probe

⚠️ Troubleshooting

لا يوجد إخراج: Check DC18~32V supply, M12 pin assignment and reverse polarity protection

Drifting readings: Check probe fouling, installation position, medium flow rate; perform calibration

Output ＜4mA: RTD element broken / sensor damage; read diagnostic information via IO-Link

📦 Optional Accessories

G1/2 welding boss, hygienic adapter

Factory calibration certificate (خياري)

IFM TA2502 Hygienic Temperature Transmitter｜Installation Method

1. Process Connection

G1/2 external thread + cone face sealing (hygienic cone seal). Sealing is achieved by compression between the sensor taper and the internal taper of the welding boss; threads are not responsible for sealing.

Matching parts: Hygienic welding boss (G1/2 internal cone), PEEK seal ring E43911 (3A hygienic certified solution)

✅ Two types of mounting bosses

1. Welding boss (most common for food/pharma CIP/SIP)

Weld the G1/2 hygienic boss onto pipe / tank wall first, polish weld seam, then install sensor. 3A compliant bosses have a leakage vent hole; medium will leak from the vent once seal fails for early warning.

2. خياري: Thermowell

For highly corrosive media, high pressure or maintenance without shutdown. Install hygienic thermowell; sensor probe inserts into sleeve, sensor can be removed without depressurizing the process.

2. اتجاه التركيب (Critical for Hygiene & دقة)
3. المفضل: Horizontal side mounting or 45° upward inclined mounting on pipeline

Medium drains naturally, no liquid pooling on probe, no dead zones, meets CIP drain requirements.

2. Prohibited: Vertical downward installation at pipe lowest point

Risk of material/liquid accumulation, incomplete cleaning, not compliant with 3A hygienic standards.

3. Tank installation: Probe inclined downward, not vertically downwards.
4. Medium flow: Direct fluid flow towards the probe to improve response and reduce fouling.

Effective immersion length EL=30 mm. The entire sensing section must be fully submerged in the medium; wall-contact-only installation is invalid.

3. خطوات التثبيت الميكانيكية
4. Shutdown & depressurize, ينظف: Confirm pipeline pressure-free, clean cone surfaces of welding boss and sensor, remove burrs, weld slag and contaminants.
5. Fit PEEK seal ring (E43911) between the cone faces.
6. Hand pre-tighten: Screw in by hand until cone faces mate, do not force cross-threading.
7. Torque wrench tightening: 30~50 Nm. Overtightening will crush cone face and permanently damage sensor. PTFE tape or thread locker are forbidden (threads do not seal; PTFE tape contaminates medium and creates hygiene dead zones).
8. After tightening, the upper M12 connector can rotate freely for orientation (hexagon locks the cone seal, upper housing can be fine-tuned for convenient wiring).
9. Pressure test for leakage before commissioning.
10. التركيبات الكهربائية (M12 4-pin A-coded connector, 2-wire 4~20mA + IO-Link multiplex)

Supply DC18~32V, 2-wire loop powered

M12 pin assignment:

دبوس1: L+ (24الخامس+)

دبوس2: Not used

دبوس3: L/ 4~20mA return, IO-Link signal

دبوس4: Not used

كابل: M12 4-core straight / angled cable. Shielded cable recommended. Route separately from power cables to reduce interference.

حماية: Fully tighten M12 connector after wiring to maintain IP69K for high pressure washdown.

5. Installation Limits & ملحوظات
6. اهتزاز: Max permissible vibration 4g. Avoid mounting near pumps, compressors and high-vibration areas.
7. Ambient temperature for transmitter head: -25~+80°C.
8. Do not strike the Φ6 thin probe; bending will damage the internal Pt1000 element.
9. CIP/SIP washdown: High-pressure spray allowed, avoid direct high-impact spray onto M12 connector.
10. For disassembly and re-installation, inspect PEEK seal ring; استبدال في حالة تلف.
11. أخطاء التثبيت الشائعة

❌ Wrapping PTFE tape on threads → medium contamination, hygiene dead zones

❌ Over-torque tightening → cone face crushing, permanent damage

❌ Vertical downward mounting at pipe bottom → material accumulation, incomplete CIP cleaning

❌ Insufficient immersion, probe only touches pipe wall → large temperature reading error & drift

❌ Signal cable routed together with power cable in same trunking → unstable 4~20mA signal

IFM TA2502 IO-Link Parameter Setting Procedure

TA2502 uses 2-wire multiplex IO-Link + 4~20 مللي أمبير. Parameters can be configured via ifm free software moneo|configure or PLC IO-Link master (AL series). No local buttons; all parameters are only editable via IO-Link.

1. Hardware Wiring Preparation
2. Supply DC18~32V, M12 4-pin A-coded

دبوس1: L+ (24الخامس+)

دبوس3: L/ IO-Link signal (shared 2-wire)

2. Sensor → IO-Link master (AL1102/AL1322/AL1402 etc.), master connected to PC or PLC
3. Power on and wait for 2s power-on delay until sensor ready; set master port mode to IO-Link mode (not DI/DO)
4. Software Preparation (moneo|configure, recommended for commissioning)
5. Download free moneo|configure from ifm official website, install on Windows PC
6. Set PC IP to same subnet as IO-Link master, connect master via Ethernet
7. Scan devices, identify TA2502; IODD device description file loads automatically

IODD file can be imported offline for pre-configuration, write to sensor after online connection.

3. Core Parameter Configuration (Most used: 4~20mA span rescaling)

Factory default: 4mA=0°C, 20mA=200°C. Hardware limit: -50 ~ +200°C, cannot exceed this range.

Operation Steps in moneo|configure

1. Select TA2502 under the port, open parameter page
2. Modify ASP (4أماه), AEP (20أماه), على سبيل المثال. ASP=20°C, AEP=120°C
3. Set damping dAP: 0.5~1s recommended for pasteurization / dynamic process; 2~5s for static tank
4. Verify Unit=°C
5. Click Write to Device
6. After writing, power cycle the sensor. Parameters are permanently saved inside sensor, retained after power loss.

⚠️ هام: After ASP/AEP modification, 4~20mA analogue output scales accordingly. IO-Link raw temperature reading is unaffected; IO-Link reads true Pt1000 measured value.

4. PLC IO-Link Master Configuration (TIA Portal etc.)
5. Add IO-Link master module in PLC hardware catalog, assign IP address
6. Set master port to IO-Link mode, scan and detect TA2502
7. Import TA2502 IODD file, modify ASP/AEP, damping in device parameter page, download hardware configuration
8. Read from PLC process data area:

Process data: Raw temperature value (16قليل)

Status byte: Sensor diagnostic bits (كسر الأسلاك, over-range, خطأ في الأجهزة)

5. IO-Link Diagnostic Reading (استكشاف الأخطاء وإصلاحها)

Diagnostic data available real-time:

1. Sensor identification: نموذج, serial number, firmware version
2. Current measured temperature (raw Pt1000 reading, independent of 4~20mA scaling)
3. Fault codes:

Element wire break: below 4mA (<3.8أماه)

Over upper / lower range alarm

Internal hardware fault → analogue output jumps to 21.5mA

4. Peak memory: الأعلى / min temperature record (resettable)
5. Parameter Backup & Sensor Replacement (Automatic Parameter Download)
6. moneo|configure can save TA2502 parameter set as file
7. After replacing faulty sensor with same model, import parameters in one click, no manual re-entry, ideal for fast line replacement in food production.
8. القيود & ملحوظات
9. ASP and AEP cannot exceed hardware range -50 ~ +200°C. AEP can be smaller than ASP (reverse span: 4mA for high temperature, 20mA for low temperature)
10. Larger dAP gives slower response and stronger noise suppression; do not use large damping for dynamic pasteurization process
11. IO-Link communication and 4~20mA share the same 2-wire loop. Communication reading does not affect analogue current output
12. If only 4~20mA is required without IO-Link communication, switch master port to analogue mode. Sensor still outputs per saved ASP/AEP settings.
13. القضايا المشتركة

Parameter write failure: Check master port in IO-Link mode, supply voltage ≥18V, M12 connector contact integrity

4~20mA unchanged after span modification: Sensor not power cycled after writing; or ASP/AEP set outside -50~200°C hardware limit

IO-Link temperature reading normal, but 4~20mA drifts: Check loop load resistance, max load 300Ω
