Terminology
Term Explanation
Compressor
element 1/2 Element 1 and element 2 stands for the low-pressure and high-pressure compressor
element respectively.
The regulator does not accept illogical settings, e.g. if the warning level is programmed
at 210˚C, the minimum limit for the shut-down level changes into 211˚C. The
recommended difference between the warning level and shut-down level is 10 ˚C.
Compressor
element 1/2 Element 1 and element 2 stands for the low-pressure and high-pressure compressor
element respectively.
The regulator does not accept illogical settings, e.g. if the warning level is programmed
at 410 ˚F, the minimum limit for the shut-down level changes into 411 ˚F. The
recommended difference between the warning level and shut-down level is 18 ˚F.
Oil Use Atlas Copco Roto-Z oil. The change interval for this oil is after 16000 running hours
or 2-yearly.
Oil filters Use Atlas Copco filters. The change interval is after 8000 running hours or yearly.
Air filters Use Atlas Copco filters. Replace the filters when the warning level is reached or yearly.
Required stop
period/Minimum
stop time Once the compressor is automatically stopped, it will remain stopped for the minimum
stop time (approx. 20 seconds), whatever happens with the air net pressure. In
automatic operation, the compressor will not be stopped by the regulator until a
standstill period of at least the sum of the minimum stop time and required stop period is
expected. However, if the decrease in air net pressure should require a new start of the
compressor, the regulator will start the compressor after the minimum stop time.
Power recovery
time Is the period within which the voltage must be restored to have an automatic restart. Is
accessible if the automatic restart is activated. To activate the automatic restart function,
consult Atlas Copco.
