Schneider XY2CH13250 สวิตช์ดึงเชือกหยุดฉุกเฉินแบบล็อค

คำอธิบายโมเดล: XY2CH series, booted push-button reset, 1NC+1NO, without indicator lamp; XY2CH13250H29 = cable entry thread changed to M20; standard version is Pg13.5.

Comparison with XY2CH13290: 13250 features only one safety NC contact; 13290 adopts dual-channel safety with two NC contacts — this is the core difference.

ข้อมูลจำเพาะพื้นฐาน

Terminal Assignment

⚠️ วิกฤติ: Only one safety NC contact; no second hardware safety channel.

สภาวะปกติ: 21-22 ปิด, 13-14 เปิด. Pulling the rope triggers mechanical latching: 21-22 เปิด, 13-14 ปิด. Restore by pressing the blue reset push-button.

Wiring Schemes

Scheme 1: High-Safety Level (PL e requires safety-relay monitoring)

1. ลวด 21-22 (เอ็นซี) to one input channel of safety relay.
2. ลวด 13-14 (เลขที่) to PLC DI for alarm feedback signal.

Since the hardware provides only one NC channel, Category 4 / PL e can only be achieved when the safety relay implements contact short-circuit monitoring. Without monitoring, max achievable safety level is PL c.

❗Do NOT externally parallel contacts; hardware only supplies one safety contact.

Scheme 2: Low-risk general-purpose equipment (PL e not satisfied)

ลวด 21-22 in series into equipment emergency-stop circuit; 13-14 for alarm feedback.

Suitable for light-duty general-purpose conveyors. Strictly prohibited for high-risk conveyor systems.

ข้อควรระวังในการเดินสายไฟ

1. Use only one cable entry; fit sealing plugs on the remaining two unused entries, otherwise IP65 protection is lost.
2. Connect metal housing reliably to PE protective earth.
3. Tighten terminals strictly to 0.8-1.2 N·m to avoid loose connections.

การติดตั้งเครื่องกล

Mechanical installation requirements are identical to XY2CH13290. Refer to the full installation manual below:

1. Max rope span 30 m; use φ3-5 mm plastic-coated steel wire rope.
2. End-position tension spring is mandatory. Rope breakage shall also trigger emergency stop.
3. First deflection pulley shall be mounted 100 mm away from switch body. Install rope clamps/support points every 5 m.
4. Mount onto rigid metal brackets only; allow slight rope sag — do not over-tension nor allow excessive slack.

Pre-power-on Commissioning (de-energised, multimeter test)

1. Reset completed: 21-22 ปิด, 13-14 เปิด.
2. Pull rope to trigger latching: 21-22 เปิด, 13-14 ปิด.
3. Press reset push-button to restore contact states.
4. Test actuation at multiple positions all along the rope path to confirm reliable triggering even at far-end positions.

การเปรียบเทียบแบบจำลอง: XY2CH13250 vs XY2CH13290

การแจ้งเตือนการเลือก: Prefer 13290 for belt conveyors and heavy-duty lines; 13250 is acceptable for light-duty general-purpose machines.

การแก้ไขปัญหาทั่วไป

1. Unintended nuisance tripping: Excessive rope tension, bracket vibration. Reduce tension via turnbuckle; reinforce mounting structure.
2. No actuation from far-end pull: Insufficient rope tension, seized deflection pulleys. Adjust tension; service pulleys.
3. Cannot reset after tripping: Persistent tensile load remains on rope. Release rope residual tension before pressing reset button.

ประเภทสินค้า: Latching emergency-stop rope-pull safety switch. Pulling the steel wire rope triggers emergency stop with mechanical latching; manual reset is mandatory. Applied to long-run conveyors, สายการประกอบ, เครื่องบรรจุภัณฑ์, belt conveyors and other machinery safety protection.

Schneider XY2CH13290 (Telemecanique Rope-Pull Emergency-Stop Switch)

รายชื่อผู้ติดต่อ: 2NC+1NO, booted push-button reset, no pilot lamp; max rope length 30  m; IP65; Pg13.5 cable entries. Suffix H29 = M20 thread.

1. Terminal Assignment

Non-actuated state: 21-22 ปิด, 31-32 ปิด, 13-14 เปิด.

Rope-pull latching: 21-22 และ 31-32 open simultaneously; 13-14 ปิด. Reset only via blue local push-button.

2. Wiring Schemes

Scheme A: Safety-relay connection (achieve PL e / แมว.4 / SIL3 — Recommended)

1. Feed independent dual NC channels 21-22 และ 31-32 separately into dual-channel safety-relay inputs. Never externally short-circuit the two NC contacts — this invalidates safety rating.
2. ลวด 13-14 NO contact to PLC digital input for rope-pull-triggered alarm.
3. แรงบิดในการขันขั้วต่อ: 0.8-1.2 น.ม. คอนดักเตอร์: 0.34-1 mm² single-wire / max 0.75 mm² for two-wire parallel.
4. Cable glands: 3 × Pg13.5; use one only; seal remaining two with blanking plugs to preserve IP65.

Scheme B: Simplified stand-alone wiring (PL e not satisfied, for basic stop-function only)

Wire both NC contacts in series into emergency-stop circuit; NO for alarm output. Cannot reach Category 4; only for low-hazard machinery.

⚠️สำคัญ: This is a mechanically latched device. It will NOT auto-reset after rope-pull actuation; manual push-button reset is required.

3. Mechanical Installation Key-Points
4. Steel wire rope: φ3-5 mm plastic-coated; max total length 30  m; fit tension springs at both ends.
5. Rope clamps: install every ≤ 5  m; add deflection pulleys to prevent rope-to-housing friction.
6. Rope tension: avoid over-tightening (nuisance tripping) and excessive slack; permit minor sag.
7. ขายึด: rigid metal construction; no flexible supports. Switch can accept rope entry from left or right side.
8. อุณหภูมิแวดล้อม: −25 ℃ ~ +70 ℃.
9. ขนาดโดยรวม (มม)

7. การแก้ไขปัญหา
8. Frequent nuisance tripping: Excessive rope tension, seized pulleys, deformed brackets, heavy machine vibration. Reduce rope tension; inspect deflection pulleys.
9. Cannot reset after tripping: Residual rope tension keeps mechanism locked. Release rope tension before pressing reset button.
10. Intermittent open safety circuit: Under-torqued terminals. Retighten terminals to 0.8-1.2 N·m; re-crimp conductors.
11. Water ingress damage: Unused cable entries not sealed with blanking plugs.

Complete Installation Operating Guide for Schneider XY2CH-Series Rope-Pull Emergency-Stop Switches

รุ่นที่ใช้งานได้: XY2CH13290, XY2CH13270, XY2CH13250 etc. Complies with EN/ISO 13850, IEC 60947-5-5, Machinery-Safety Directives.

⚠️ Safety Precondition: Perform all installation, wiring and commissioning with equipment de-energised under Lock-Out-Tag-Out (หัวใจ). This is a tension-type rope-pull switch; proper pre-tension is required. Rope breakage shall also trigger emergency-stop protection.

1. การเตรียมการก่อนการติดตั้ง

1.1 เครื่องมือ & Accessories List

1.2 Environmental Verification

1. อุณหภูมิในการทำงาน: −25 ℃ ~ +70 ℃; ระดับ IP65. Avoid heavily corrosive and high-impact locations.
2. Max effective rope-protected length 30  m. Install an additional rope-pull switch if span exceeds this limit.
3. Operating rope height above ground: 0.6-1.1 ม, easily reachable by personnel; no obstacles obstructing the rope path.
4. All mounting brackets must be rigid metal. Thin-sheet / flexible supports are forbidden; vibration will cause false triggering.
5. Mechanical-body Mounting Procedure
6. Secure the switch body

Fasten with M8 bolts through the two side mounting holes onto rigid machine frame; tightening torque 4 N·m. Align switch rope-exit direction with rope routing; do not twist the rope-pull lever mechanism.

Maintain 100 mm distance between switch body and first deflection-support point. Larger distance causes insufficient actuation stroke.

2. Fit deflection pulleys

Fit deflection pulleys wherever the rope changes direction. Total deflection-angle sum ≤ 180°. Sharp bends and hard kinks are prohibited.

Install support / rope-clamp assemblies every 5 m along straight runs to limit rope sag.

Pulleys shall rotate freely without binding. Rope must not rub against machine frames or enclosures.

3. Steel-wire-rope & end-spring assembly (ขั้นตอนที่สำคัญ)

1) Attach one rope end to the XY2CH rope-pull eyelet.

2) Thread rope through all deflection pulleys.

3) Fit end-position tension spring at the far rope end. Anchor the spring’s opposite end to rigid machine frame. Omission of this spring is a major safety hazard — pulling towards the switch will fail to trigger E-stop.

4) Secure rope with at least two rope clamps. Do not clamp over the sheath-stripping transition zone.

5) Adjust total rope tension via turnbuckle: keep rope moderately taut with minor sag. Do not over-tighten; do not allow excessive slack.

Over-tension: vibration-induced nuisance tripping. Under-tension: no reliable actuation from far-end positions.

4. Mechanical acceptance check

Rope free of twist, kinks and abrasion. Avoid large-area sheath stripping to prevent corrosion.

Full-rope-travel movement is smooth without binding.

ตรวจสอบ: rope breakage will cause spring retraction and trigger emergency-stop.

3. Electrical Wiring Procedure

XY2CH13290 terminals: 21-22 เอ็นซี1; 31-32 เอ็นซี2; 13-14 เลขที่. Metal housing includes PE earth terminal. Housing must be reliably connected to PE protective earth.

1. Remove four cover screws and open housing.
2. Cable-entry handling:

Standard units: 3 × Pg13.5 threaded entries; H29 variants: ม20.

Use only one entry for control-cable feed-through. Tighten original sealing blanking plugs on the other two unused entries (torque 1 N·m). Failure destroys IP65 protection and causes water ingress.

3. การเดินสายไฟเทอร์มินัล (for PL e / แมว.4 / SIL3 safety-loop):

Feed dual safety NC contacts 21-22 และ 31-32 into separate safety-relay dual-channel inputs. Never externally short-circuit the two NC contacts — safety rating will be lost.

ลวด 13-14 NO contact to PLC input for rope-pull-trigger-alarm signal.

หน้าตัดของตัวนำ: single-wire 0.34-1 mm²; max 0.75 mm² for two-wire parallel. Terminal tightening torque 0.8-1.2 N·m.

4. Connect PE protective-earth wire to housing earth terminal for EMC and shock-hazard protection.
5. Refit cover and evenly tighten four cover screws.

❗Simplified wiring (not for high-hazard machinery): Series-connect both NC contacts into general-purpose emergency-stop circuit. This provides only basic stop-function and does not achieve Category 4 safety rating. For low-risk equipment only.

4. Pre-power-on Static Commissioning (de-energised, multimeter measurements)
5. Normal reset-completed state

Multimeter readings: 21-22 ปิด, 31-32 ปิด; 13-14 เปิด.

2. Manually pull rope to trigger mechanical latching

Multimeter readings: 21-22 เปิด, 31-32 เปิด; 13-14 ปิด.

Latching is maintained; contacts will not auto-recover.

3. Press blue booted reset push-button; contacts return to initial status.
4. Simulate actuation at multiple positions along rope path: near switch, mid-span and far-end. Reliable latching actuation must occur at every position.

Poor far-end actuation: reduce rope tension or check for seized pulleys.

5. Simulate rope breakage: spring retraction must trigger emergency-stop latching.
6. Live-machine Functional Test
7. Energise machine and safety-relay system.
8. Test 1: Pull rope near switch → controlled machine shutdown; safety-relay fault indication. Manual reset at switch body AND safety-relay reset are required before machine restart. No automatic-power-on after supply restoration permitted.
9. Test 2: Pull rope at mid-span and far-end positions. Confirm controlled emergency-stop at all points.
10. Test 3: Verify PLC alarm signal (13-14 เลขที่) correctly reports rope-pull-trigger events.
11. Installation Acceptance Criteria
12. เครื่องกล: Rigid mounting brackets, free-running pulleys, intact tension springs, correct rope tension, no mechanical interference or friction.
13. การป้องกัน: All unused cable entries sealed with blanking plugs; cover screws tightened; PE-earth connection intact.
14. ไฟฟ้า: Dual-channel NC contacts fed independently to safety-relay inputs (no external short-circuit). Multimeter test sequences fully compliant.
15. มีประโยชน์ใช้สอย: Reliable latching E-stop from any rope-span position; manual-only reset; rope-break triggers emergency-stop.
16. Installation-related Fault-Finding Table

8. Periodic-maintenance Requirements (to be documented in machine-maintenance manual)
9. Weekly visual inspection: rope abrasion, loose rope clamps, deformed springs, loose mounting brackets.
10. Monthly full-functional test: trigger emergency-stop at multiple rope-span positions.
11. Quarterly inspection: re-verify terminal torque and PE-earth integrity; inspect rope-sheath wear.
12. Immediately replace steel-wire rope if wire-strand breakage or sheath damage is observed.

Supplementary note: XY2CH shall not be treated as a general-purpose limit switch. Permanent rope anchoring without end-position tension spring constitutes a serious safety violation.
