Tankvision Gauge Link Maintenance
Hauser 37
9 Maintenance
The Tankvision Gauge Link normally requires no routine / preventive maintenance other
than periodically checking for signs of the enclosure ventilation slots becoming blocked with
dust, etc.
9.1 Foreign object/liquid ingress
If (or it is suspected that) any liquid or conductive object or debris has entered the enclosure
of the Tankvision Gauge Link, the mains supply to the equipment must immediately be
isolated.
The enclosure is not intended to be opened or dismantled by the user. If possible the foreign
object may be retrieved by dismounting the Tankvision Gauge Link and gently tilting and
shaking the enclosure until the object falls out.
In the case of water ingress, place the Tankvision Gauge Link in a warm location and allow
the enclosure to thoroughly dry out.
Do not reinstall the Tankvision Gauge Link until it is certain that all foreign object / debris
or contamination has been completely removed from the enclosure. On first power-up check
for signs of unusual or incorrect operation, burning smells or smoke emanating from the
enclosure.
If there is any doubt that debris or contamination remains within the Tankvision Gauge Link
enclosure or that the internal parts may have been damaged, the unit should be returned to
the manufacturer or one of its authorised agents for repair.
9.2 Insulation/Hi-Pot testing
The Tankvision Gauge Link undergoes all necessary tests during manufacture. It is not
necessary, and indeed undesirable, to perform routine high voltage insulation testing on the
unit after installation. Repeated high voltage testing may cause degradation of insulation
characteristics which may impair safety.
If it is desired to perform high voltage insulation testing on the electrical installation/cabling
then it is recommended that the mains supply connector is unplugged at the Tankvision
Gauge Link and placed away from the enclosure.
