9.1 Personal Node troubleshooting
A 'lock out, tag out' program could require, for example:
• A physical tag be attached to the device identified as, eg 'tagged out of service'.
• Tagging to occur before taking a replacement device.
• The device set aside and not replaced in the dock.
• Reporting to the Supervisor, or equivalent, before starting your next scheduled task.
Table 15 Personal Node troubleshooting table
Problem
Test
Action for failed test
1) Physical
damage.
Inspect the device for obvious
physical damage and ensure that it
appears to be in good physical
order.
Check for:
• Signs of breakage or dropping.
• Tampering.
Stop using the device. Have the device
checked by qualified and authorised
personnel. See your Supervisor to obtain a
replacement.
2) Environmental
problems.
• Device is wet (eg
condensation).
• Device covered in dirt or mud.
Clean and dry the device.
3) Battery fault or
dirty charging
contacts
A flashing red Charge LED with the
Personal Node docked could be a
faulty battery OR dirty charging
contacts on the Personal Node or
Charging Dock.
Note that a solid red Charge LED is
charging OK and solid green Charge LED is
fully charged.
• Clean contacts on Personal Node and
dock.
Refer MSDS for electrical contact cleaner used at
your site.
• Try a different charging slot.
• If a slot is faulty, mark the slot as U/S
(eg paper tape and marker pen) and
advise Supervisor.
• If Charge LED flashes in different slots
and after cleaning all contacts then
battery is faulty.
4) Incorrect start-
up sequence.
• Status LED flashing at startup.
• LEDs flash red continuously.
• All LEDs are red and remain
on.
• No audible alarm at start-up.
Return to dock for at least 10 minutes and
until the Charge LED on the device
indicates solid green. See Supervisor if
problem persists.
If a Personal Node is deemed unserviceable, implement the site 'lock out, tag out'
program and return for repair using the
RMA Procedure
on page 66.
Wear protective gloves if handling electrical contact cleaner and refer to the MSDS.
