🛠️ Installation & メンテナンスガイドライン

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) 利用可能
4. Washdown: High-pressure spray permitted (IP69K). Avoid heavy mechanical impact on probe

⚠️ Troubleshooting

出力なし: 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 / センサーの損傷; read diagnostic information via IO-Link

📦 Optional Accessories

G1/2 welding boss, hygienic adapter

Factory calibration certificate (オプション)

IFM TA2502 Hygienic Temperature Transmitter｜Installation Method

1. プロセス接続

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. オプション: サーモウェル

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. 取付方向 (Critical for Hygiene & 正確さ)
3. 好ましい: 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. 中流量: 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. 機械的な取り付け手順
4. Shutdown & depressurize, クリーン: 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. 締め付け後, 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. 電気設備 (M12 4-pin A-coded connector, 2-wire 4~20mA + IO-Link multiplex)

Supply DC18~32V, 2-wire loop powered

M12 pin assignment:

Pin1: L+ (24V+)

Pin2: Not used

Pin3: L/ 4~20mA return, IO-Link signal

Pin4: Not used

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

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

5. Installation Limits & 注意事項
6. 振動: 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; 破損した場合は交換してください.
11. Common Installation Mistakes

❌ 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 + 4～20mA. 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

Pin1: L+ (24V+)

Pin3: 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 (4ミリアンペア), AEP (20ミリアンペア), 例えば. 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.

⚠️重要: 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 (16少し)

Status byte: Sensor diagnostic bits (wire break, over-range, hardware fault)

5. IO-Link Diagnostic Reading (トラブルシューティング)

Diagnostic data available real-time:

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

Element wire break: below 4mA (<3.8ミリアンペア)

Over upper / lower range alarm

Internal hardware fault → analogue output jumps to 21.5mA

4. Peak memory: マックス / min temperature record (resettable)
5. パラメータのバックアップ & 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. 制限事項 & 注意事項
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. よくある問題

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
