Switching on the maxium® smart Beam
The maxium® smart Beam is fed and controlled by the maxium® smart C. When switched on, independently
of the maxium® smart C it will perform a self-test, checking the functions of the gas flow control and the
status of the argon gas supply.
If the active program of the maxium® smart C does not comprise any argon-supported currents, after the
self-test the beamer will change to a passive mode, its status light remaining dark. If the program comprises
any argon-supported currents, after passing the self-test the status light will be lit green.
In case of an error the status light will be lit red, and the status line on the screen will show a message
together with an error number.
Typical messages during the self-test of the maxium® smart Beam are the following:
•
Argon Beamer Warning: Inlet pressure too low
The pressure measured at the gas inlet is too low to ensure the required gas flow at the end of the
applicator under all operation conditions. Make sure that the argon gas supply from the pressure
reducer is connected to the rear of the beamer, and the angle valve of the cylinder opened. If the
gauge at the pressure reducer indicates a pressure of less than 10 bar, operation with the residual
pressure is not expedient.
The cylinder should never be completely emptied!
•
Argon Beamer E55-59: Offset failure
The pressure sensors of the maxium® smart Beam are sensitive to temperature changes. In case of
temperature changes, the temperatures of the individual components of the unit will adapt to the new
temperature, but often with very different speeds. If components of the pressure sensors have
different temperatures, the pressure sensors will yield output signals which are liable to incorrect
interpretation. If a beamer is moved from a very cold to a warm environment, due to the resulting
temperature gradient the self-test may not be passed. In this case, allow the maxium® smart Beam to
warm up for half an hour with the unit switched on. If the self-test is again not completed successfully,
there is a malfunction.
For additional messages see section 13.5 “Messages from the Argon Beamer and the Fume Suction
System”, page 112.
9.3.1
Noise during operation
In intervals of a few minutes, the maxium® smart Beam will check the calibration of the gas flow control.
To this purpose, a small amount of gas is released into the inside of the beamer, and both the activity of the
solenoid valves and the gas flow will be heard. This is not a malfunction of the beamer, but serves to ensure
maintenance of the accuracy of the operating data.
