20AP2:9 Gas flo w monitor
AristoMig, AristoTig
Terminals G4 and G5 are intended for use with a gas flow monitor. The
processor reacts to voltage flanks from the input.
The AristoMig and AristoTig units are not normally fitted with gas flow monitors,
which means that this input must be short --circuited by a link. If the link is open
the control panel shows fault code 32.
AristoArc
Terminals G4, G5 and resistors R8 -- R10 are not mounted on the board that is
delivered with the machine.
Spare part circuit boards are delivered with all components fitted. Terminals G4
and G5 are intended for u se with a gas flow monitor. AristoArc 400 units are
not fitted with gas flow monitors, which means that G4 -- G5 must be short--
circuited by a link. If the link is open the control panel shows fault code 32.
If version no. 1 of control board 20AP1 is used there is no need to use the link.
20AP2 Component positions
The circuit diagram and component positions shows all the components with
which the board may be fitted: the exact choice of components varies,
depending on in which machine the board is used.
Spare part circuit boards are delivered with all components fitted.
