The cycle is started by pressing the two-hand release. The output READY_
OUT is deactivated and the power loss measurement (Pv) is signalled by the
output US_ACTIVE_OUT.
After a successful Pv measurement, the solenoid valves (MV_1,2_OUT) are
actuated and the press leaves the rest position. This is signalled by the
output RESTPOS_OUT.
When the trigger pressure has been reached, the ultrasound starts. This is
signalled by the output US_ACTIVE_OUT.
After the welding and solidification phase, the outputs MV_1_OUT and
MV_2_OUT are reset. This returns the press to the rest position. The output
RESTPOS_OUT is displayed when the press has reached the rest position.
As soon as the generator is ready for the next welding process, the output
READY_OUT is activated. The output GOOD_PART_COUNT_OUT signals
that no errors occurred during welding. The signal is active until the next
cycle starts.
