5.
RUN mode
In this condition, key in position "RUN", the CS-I start cycle inputs are checked, and if active
it is possible to start and manage the preset welding cycle.
5.1.
Start cycle inputs and concomitantly
If the start cycle inputs are present at CS-I power on, it remains in NOT READY! indicate
the presence and awaiting removal inputs.
For the start of welding cycle the CS-I operates a control signal connection between the
common Pb Com and each of the other signals Pb A, Pb B, Pb C, Pb D (pre-stroke)
The concomitantly time out is 400 ms, after which it is reported the request for removal of
the Push button inputs.
OTHERWISE IT REMAINS IN CHARGE AT THE CUSTOMER THE CERTIFICATION
RULES "DUAL HANDS CONTROL" AS OFFICIAL RULES AND BY ALL OF THE
SECURITY SYSTEMS OF OVERALL MACHINE.
If the start cycle is operated by pedals, signals for the start cycle 1 or 2 are given by the
inputs PEDAL1 or PEDAL2
In spot mode, the start of the cycle occurs with the assertion of the inputs as shown in the
table:
D
uring the spot cycle, the entry of Pb C causes the interruption of the welding, as if they were
made time set.
Seam-mode, the start of the cycle occurs with the assertion of the inputs as shown in the
table, the welding current depends on the initial presence or absence of inputs Pb B and
Pb C, at the beginning of the cycle:
D
During the welding cycle seam, the presence or absence of inputs Pb B and Pb C causes
the exchange Current, while the end of the cycle is determined by the removal of the signal
