around to facilitate heat dissipation.
Temperature and Humidity Requirements
1. To ensure the normal operation and the service life of the equipment, temperature and humidity
in the operating environment should be up to standard.
2. Long-term operation in an environment that does not meet the temperature and humidity
requirements will cause damage to the equipment.
3. Operation in an environment with high relative humidity is most likely to cause poor insulation of
the insulating material and even leakage. Sometimes, changes in the mechanical properties of
materials and corrosion of metal parts are also prone to occur.
4. Operation in an environment with low relative humidity will cause the insulating sheet to dry and
shrink, and meanwhile, most likely generate static electricity, which will harm the circuits in the
equipment.
5. Operation in an environment with excessively high temperature will be more harmful and will
greatly reduce the reliability of the equipment. The long-term high temperature will also affect the
service life and accelerate aging.
Cleanliness Requirements
For the environment where the equipment is located, there are strict requirements on the salt, acid,
and sulfide contained in the air. Some harmful substances will accelerate the corrosion of metals and
the aging of certain parts. Intrusion of harmful gases (sulfur dioxide, hydrogen sulfide, nitrogen dioxide,
chlorine, etc.) should be avoided.
Power Requirements
Kit voltage input:
1.The input voltage should be within the range of 12±1V; a lower input voltage is allowed, but it will
affect the accuracy.
2.The input voltage should be within the range of 24±1.5V. The impact on accuracy will be reduced
after the excavator is started.
