6. CLEANING AND MAINTENANCE.
●
Disconnect the ZRi02 power supplier from mains.
●
Check the earthing connection quality.
Clean the scale and the housing with a slightly moistened cloth. You can use typical
domestic cleaning agents.
For clearing an overlay of the indicator do not use agents that can mechanically
scratch the surface. It includes an internal conductive layer that is important for save
operation.
Platform levelling feet and shock absorbers are made of rubber. Within the
hazardous area they need to be cleaned with a slightly moistened cloth. Moisture
protects against gathering electrostatic charges.
Cleaning should be performed when there are no explosive gases in the
atmosphere.
There is forbidden to us concentrated acids, bases, solvents or alcohol for
cleaning WPT/4P…H/EX scales.
There is also forbidden to use compressed air and high pressure washing
equipment.
7. TECHNICAL SURVEYS.
Technical surveys performed by the trained personnel at least once during every
three months.
●
During every survey following things should be checked:
−
earthing quality: the quality of fastening to the housing and the resistance of
connection - max. 100
Ω
,
−
quality of the connection between the platform and the indicator (pliant steel pipe
connecting the two subassemblies).
The damage and loosing one of connection is inadmissible.
−
electrical connection between the housing and the platform - max. resistance
between the weight pan (put on) and the housing should be lower than 100
Ω
.
−
stability and levelling of the scale.
