Maintenance and storage

WD-20EFirmware: WD-20E mount build; AHC 1.1.0 interface reference

In this chapter

10.1 Routine inspection​

Before each session, inspect:

  • Tripod/pier attachment, leg locks, adapters and extension joints.
  • Saddle clamps, dovetail engagement and telescope attachment hardware.
  • Counterweight shaft engagement, weight locks and end-retention hardware.
  • Latitude range fastener, latitude locks, azimuth locks and adjuster condition.
  • Cable insulation, connector retention, controlled slack and snag points.
  • Housing condition and any damage or looseness after transport.

Perform these checks with the equipment stopped and supported. Remove a damaged cable from service. Investigate new play, resistance or abnormal noise rather than tightening unrelated components or changing motor settings.

10.2 Cleaning and care​

CAUTION · Liquids and solvents

Isopropyl alcohol may be used to clean the mount's exterior surfaces. Apply it to a soft cloth, not directly to the mount. Do not spray cleaner into the mount, rinse it, or use abrasives or other strong solvents on the housing, labels or display. The operating-temperature specification does not establish a waterproof rating.

  1. Stop the equipment, make the mechanical load safe, switch off and disconnect the supply.
  2. Remove loose dust with a soft, clean brush or cloth.
  3. Wipe the mount's exterior surfaces with a soft cloth, lightly moistened with isopropyl alcohol if needed; keep liquid away from ports, openings, labels and the controller display.
  4. Inspect connectors without scraping contacts or introducing conductive debris.
  5. Allow damp equipment to dry in a clean, ventilated environment before storage or reconnection.

After a dewy session, disconnect power safely and dry the exterior. Do not seal wet equipment in the foam case. If water entered a connector or housing, leave it unpowered and seek advice before restarting.

The drive does not need user belt-tension adjustment. Do not open the reducer or add lubricant to internal components without an approved service procedure.

10.3 Disassembly and transport​

WARNING · Changing load distribution

The tripod can become unstable as one side of a counterweighted assembly is unloaded. Support the equipment and plan the removal sequence for your actual setup. Never leave an unsecured weight on its shaft or an unsupported telescope in a loosened saddle.

  1. End the sequence, stop guiding, and use a safe Home/Park position if its movement route is clear.
  2. Wait for motion to stop. Support or reduce the load so power-off is safe within the brake's holding capability.
  3. Switch off, disconnect the power source and remove connected cables without pulling on their wires.
  4. Support the telescope, release its clamps and lift it away. Remove accessories separately when that makes handling safer.
  5. Remove counterweights while supporting each weight, then remove the shaft as appropriate.
  6. Hold the mount securely while releasing its attachment to the tripod/adapter.
  7. For case fit, change coarse latitude only with the telescope removed and the body supported. Secure the range fastener and locks afterwards.
  8. Remove the azimuth fine-adjustment handles before transport and store them securely with the other removable parts.
  9. Place the dry mount and controller in the fitted case. Arrange cables, connectors, handles and accessories so they cannot press against or strike the mount's surface during transport; contact and vibration can leave scratches. Ensure nothing is compressed by the lid.

Carry the mount and support separately rather than moving a fully assembled system over uneven ground. Keep the case cushioned and secured during transport; an aluminum case is not a reason to expose the contents to impacts.

10.4 Long-term storage​

Store the equipment clean, dry and unpowered, away from condensation, dust and corrosive environments. Keep fasteners and approved cables identified with their purpose so similar connector types are not confused on the next setup.

Before returning to service:

  1. Inspect the mount, support and cables for damage or corrosion.
  2. Reassemble and reassess payload/stability rather than relying on the last installation.
  3. Check versions, observing data, Home/Park state and safety settings.
  4. Review AEB calibration requirements if the attached equipment configuration changed.
  5. Perform a short supervised low-speed movement/STOP check before an automated session.

GPS reception may take longer after relocation or a long interval without use. Confirm valid time/location instead of starting from stale displayed data.

10.5 Service and repairs​

User care consists of external inspection, approved installation adjustments, cable replacement with compatible parts, cleaning and supported software/firmware procedures. Opening the housing, modifying wiring, changing internal components or recalibrating a suspect encoder reference requires a product-specific service procedure.

Contact support for impact damage, repeated motor or protection errors, unreliable Home/reference behavior, electrical damage, abnormal noise or unresolved movement problems. Supply the information in 8.8.

Before shipping for service, stop and unload the system, photograph the equipment's condition, preserve diagnostic records and follow the return instructions. Remove accessories not requested for diagnosis and use the fitted case plus appropriate outer shipping protection.

Warranty coverage and return arrangements follow the terms applicable to your purchase channel and region. Keep the invoice and serial number and ask your dealer or WarpAstron for the applicable service process.
