Functional test
4.4.1. Self-test
Figure 4-7:
Self-test
When the argon device is switched on, it runs a self-test that checks the controls
and indicators, acoustic signal, microprocessor and hardware for proper operation.
The argon device performs a new self-test when it is again activated after being
switched off for at least 15 seconds or after being in standby mode for at least
8 hours.
4.4.2. Cyclical test during operation
During operation, safety-relevant functions and signals are tested cyclically. If
serious faults are detected, the argon device switches off and the fault indicator on
the display lights up red. For further information, see Section “Detecting and
Correcting Faults“, page 34.

Operation
5.1.
Activation and alarm signals
When the purging process is active, the ARC PLUS emits a continuous acoustic
signal at a fixed volume.
Activation and alarm signals are generated by the HF generator.
The volume of the activation signal should be increased as necessary for use in
relatively noisy surroundings. This can be done using the menu of the HF
generator.
5.2.
Emergency stop
The argon device can be switched off at any time by using on/off switch
16
as an
emergency stop switch.
