Derui chamberQ: Do you provide remote technical support for installation, troubleshooting, and training?
A: Yes, absolutely. Comprehensive remote engineering support is a standard, non-expiring component of every Derui equipment purchase—never an add-on or paid upsell. Our global technical support architecture spans three dedicated operational layers to ensure 99.8% machine uptime for international laboratories.
1. Three-Layer Technical Support Implementation Matrix
| Deployment Phase | Engineering Deliverables & Protocols | Communication & Access Tools | Target Turnaround / Response Time |
|---|---|---|---|
| Phase 1: Pre-Installation Site Prep | CAD foundation layouts, power matching (220V/380V, 50/60Hz), pneumatic line specs (0.6–0.8 MPa header pressure). | Engineering Drawings + Pre-arrival Zoom/Teams Consultation | Provided 14 days prior to equipment arrival |
| Phase 2: Remote Commissioning & DAQ Calibration | Live axis homing, S-beam load cell zeroing, pneumatic closed-loop PID tuning, and ISO 17025 baseline verification. | TeamViewer PC remote desktop + WhatsApp/WeChat 4K Live Video | Scheduled on shipment delivery day (1-on-1 session) |
| Phase 3: Lifetime Troubleshooting & Parts Delivery | Diagnostic PLC log analysis, sensor drift correction, express DHL/FedEx dispatch of replacement valves and encoders. | 24/7 Ticketing System + Global Service Desk Hotline | < 4 Hours initial response; parts shipped within 24h |
2. Standard Remote Commissioning SOP (Step-by-Step)
On delivery day, your plant technician works directly with a senior Derui application engineer to execute the live power-up sequence:
- Utility Connection Audit: Engineer verifies main air supply pressure stability (minimum 1,200 L/min FAD for multi-station rigs like the DR-J501 Multi-Station Sofa Tester).
- Software Desktop Connection: Remote login to the industrial PC touchscreen via TeamViewer to load factory-calibrated PLC firmware.
- Load Cell & Encoder Calibration: Execution of baseline load cell verification using certified standard deadweights, validating accuracy within ±0.2% FS.
- Operator Training Run: Guided execution of a mock 1,000-cycle test run (e.g., BIFMA X5.1 Section 8 & 10 protocols on the DR-J609 Dual-Axis Tester).
3. Model-Specific On-Demand Video Training Portal
Every equipment purchase grants unlimited access to Derui’s high-definition video engineering library, including step-by-step operator guides:
- DR-J103 Mattress Rollator Portal: Hexagonal drum changing, surface profile laser zeroing, and EN 1957 hardness calculation setup.
- DR-J605 Star Base Fatigue Portal: 20,000 N hydraulic platen alignment and BIFMA Section 16 proof load clamping.
- DR-J801 Foam IFD Tester Portal: ASTM D3574 pre-flexing routines and hysteresis loss percentage software reporting.
🛠️ Express Hardware Replacement Guarantee:
Over 90% of technical inquiries are solved remotely within one business day via PLC parameter adjustment. In the rare event of a hardware component failure (e.g., solenoid valve, S-beam transducer, optical encoder), replacement parts are dispatched via priority international express (DHL/FedEx) within 24 hours, accompanied by a live video-guided swap tutorial.
