ZX300M Basic Maintenance for On-site Personnel

Overview

This article describes the routine maintenance tasks that on-site personnel can carry out on the ZX300M lidar system every six months. These checks are intended to maintain reliability and data quality between scheduled return-to-base services. This article does not replace manufacturer servicing requirements.

Who this is for

This article is for on-site personnel responsible for routine inspection and upkeep of an installed ZX300M system. It is written for non-certified personnel with basic technical competence.

Prerequisites

ZX300M installed and commissioned
Safe access to the unit in accordance with site rules
Approved access equipment if working at height
Clean water and lint-free cloths
Manufacturer-approved grease for Subconn connectors
Completed maintenance log or site record sheet

Safety notes

The ZX300M contains a laser system. The lidar must not be powered during cleaning or inspection.
The ZX300M has no internal power switch. Power is isolated only by removing the external power supply.
Do not rely on visual indicators alone to confirm the system is safe.
Electrical isolation must be completed before any maintenance activity.
There are no user-serviceable parts inside the ZX300M. Do not open the unit housing.
Tasks beyond those listed in this article must be escalated to WISE Group or the ZX300M manufacturer. For current WISE Group contact details, refer to your service agreement or the WISE Group support portal.
If any defect, damage, or abnormality is observed during inspection, do not restore power. Tag the unit as out of service and report immediately to your supervisor and WISE Group support.

Step-by-step

The following checks may be carried out by on-site personnel as part of routine six-monthly basic maintenance. These checks are visual and non-invasive.

Periodic maintenance checklist (6‑monthly)

Washer fluid level – check and top up if required using approved fluid
Subconn connectors – visually inspect and ensure connectors are seated; apply approved grease if dry
Lidar window – clean using a damp, lint-free cloth and clean water only
Wiper blade condition – visually check for wear or damage
Lidar base fasteners – visually confirm fasteners are present and secure

Do not dismantle, open, or adjust the ZX300M as part of basic maintenance.

Validation / What “good” looks like

All checklist items completed with no defects found

Lidar window is clean and unobstructed
No visible damage, loose connectors, or alarms after power is restored
ZX300M powers up without alarms
Window is clean and unobstructed
Wiper operates normally during rain or test cycles
No loose connectors or visible damage
System resumes normal data collection
Recording your maintenance
After completing all checks, record the date, findings, and any actions taken in the site maintenance log. If any items were escalated, note the escalation reference. Retain records for audit purposes.

Troubleshooting

Symptom: Lidar does not power up
Possible cause: Power not restored or temperature out of range
Action: Verify external power and allow warm-up time

Symptom: Poor data quality after cleaning
Possible cause: Residue on window
Action: Re-clean using clean water only

Symptom: Repeated wiper faults
Possible cause: Worn blade
Action: Escalate for service
