8 MAINTENANCE ACTIVITIES
The Personal Nodes (nodes) and Personal Node Charging Docks (docks) do not require any
specialised maintenance other than basic operational checks and cleaning. Also, see Troubleshooting
on page 56.
For sites with many hundreds of nodes, consider identifying nodes with labels to indicate
a ‘maintenance group’ with groups being checked on a staggered maintenance cycle.
Personal Node configuration checks are not required unless the device is not functioning
as expected.
Each Minetec device should be checked according to the following Maintenance Schedule as a
minimum.

8.1 Personal Node checks
The Personal Node has an internal antenna and an LED interface shown in Figure 1 Personal Node -
isometric view and Figure 2 Personal Node - top view on page 12.
The Personal Node should be kept clean to provide:
• Ease of use (eg push button, belt clip).
• Ensure best charging performance.
• Visible alarms (LEDs) can be seen easily.
• Audible alarms can be heard. This is particularly important to prevent progressive degradation of
the audible alarms.
• Best RF conditions for communications.
The Personal Node has ingress protection of IP66/67 (Dust and water tight) and requires minimal
maintenance. In general, Personal Node care includes:
• Do not use harsh abrasive or conductive materials on the body or charging contacts.
• Keep the device free of dust and dirt build-up, as this may impact the devices RF path and
useability. If there is a large amount of dirt or dust, this can be cleaned off, using a firm brush or
compressed air, if permitted and available at your site.
• Persistent dirt can be removed using a slightly damp soft cloth (use only a mild detergent).
8.1.1 Before you start
Before commencing any work, ensure that you have:
• All required onsite permissions.
• Planning approval and permit to work documents per operational and HSE.
• Site 'lock out tag out' system (eg out of service tags).
