Resetting Power Supply & Interpreting LED Indicators (LYN Series)

This article explains how to safely reset the power supply, interpret common LED indicators on LYN-series units (LYN‑X200 / LYN‑X300 / LYN‑X500), run diagnostics, collect logs and photos, and—if required—how to request and order a replacement power supply (PSU). Follow the Safety & Pre-checks before opening any covers. If the reset and diagnostics do not clear the fault, use the Spare Parts webform (link at the end) and include the required fields listed below.

Who should use this article

• On-site technicians and trained customer staff performing first-line troubleshooting.
• Support agents using AI or manual workflows to respond to customer inquiries about power / LED faults.
• Spare Parts and Fulfillment teams to validate orders and shipment information.

Symptoms (common)

• Amber or red LED on the power panel after startup.
• Unit fails to boot or repeatedly reboots.
• Audible fan noise or unusual PSU vibration.
• Intermittent operation or sudden shutdowns.
• PSU diagnostic codes such as PWR‑01 or PWR‑02 (see Diagnostics section).

Safety & prerequisites (must read)

1. Only trained personnel should remove covers or work inside the unit. Observe local safety regulations.
2. Isolate mains power and engage lockout/tagout where required.
3. Use ESD precautions when touching internal components.
4. Have basic tools: insulated screwdriver, camera (phone), USB drive (or USB port access to export logs).
5. Record the machine model and serial number before beginning (e.g., LYN‑X300 — Serial: LYNX300‑SN‑A12345).

Step 1 — Safe power reset (quick attempt)

1. Save any active work and perform a controlled shutdown via the device UI (Menu → System → Shutdown).
2. Isolate mains power at the breaker or mains switch. Wait at least 60 seconds to let capacitors discharge.
3. Remove the chassis access cover following the user manual. Keep screws in a safe place.
4. Visually inspect the PSU area for loose connectors, burnt smells, or damaged cables. Reseat the 24V and mains connectors by unplugging and plugging them back in.
5. Reinstall the cover, restore mains power, and perform a controlled power on.
6. Observe the LED sequence:
   • Green steady — normal operation.
   • Amber steady or blinking — degraded PSU or warning.
   • Red steady — critical fault; replacement likely.

If the LED returns to green: monitor the unit for 48 hours and consider scheduling a preventative inspection if intermittent problems occur. Log this interaction in the ticket and attach confirmation photos if available.

Step 2 — Run built‑in diagnostics and export logs

1. From the control panel: Menu → Diagnostics → PSU Test (or Diagnostics → Run All Tests).
2. Run the PSU Test and note any returned error codes. Typical codes:
   • PWR‑01 — PSU voltage out of range (degraded).
   • PWR‑02 — PSU failed self‑test (recommend replacement).
     (Note: actual code list may vary by firmware — include the code shown in the diagnostic log.)
3. Export the diagnostics log: Menu → Diagnostics → Export Log → save to USB (or Export → DiagnosticLog.txt).
4. Attach the exported DiagnosticLog.txt to the support ticket or webform. If possible, also take a photo of the PSU label (serial/manufacturer sticker) and the power panel.

Interpreting common outcomes

• Reset → Green LED = resolved (monitor for recurrence). Mark ticket Resolved.
• Amber LED + no diagnostic codes = monitor and request additional logging; consider scheduling on‑site inspection if intermittent.
• Amber + PWR‑01 or Red + PWR‑02 = escalate to Spare Parts (replacement PSU likely). Proceed to “Ordering a replacement” below.

When to contact Spare Parts / escalate Contact Spare Parts if ANY of the following:

• LED remains amber or red after reset and diagnostics.
• Diagnostics return PWR‑01 or PWR‑02 (or equivalent critical PSU codes).
• Visible damage, burnt smell, blown capacitors, or fan failure.
• Unit still under intermittent failures that affect production and passive fixes fail.

How to order a replacement PSU (information Spare Parts requires) 

When creating a spare-part request, provide the following exact information. This ensures the Spare Parts team can verify compatibility, check stock, and process shipment without delay:

Required information (include in the webform or email)

• Customer number / account number (if available)
• Shipping method (select one): Standard (5–7 days) / Express (2–3 days) / Next Business Day (overnight)
• Full customer shipping address (include recipient contact & phone)
• Machine model & Serial number (e.g., LYN‑X300 — LYNX300‑SN‑A12345)
• Part name and/or part number requested (e.g., PSU‑1200) — if unknown, state “PSU — please verify fit for model”
• Diagnostics log file (attach DiagnosticLog.txt)
• Photos: power panel, PSU label, any visible damage
• Preferred delivery date / SLA requirement (if urgent)
