Description of PRC7000 outputs

Description
• The started process is finished and the procedure was ok.
• The signal becomes active at the end of the welding cycle (end of the closing
time) and remains set until the start signal is reset.
• The "Weld complete" output remains set after the heatsealing process as long
as "Program start" is present.
• If the "Program start" was cancelled before the end of the process, or is not set
for "Reset fault with WC", the progress contact is output as a 10ms pulse.
• If the procedure was not correct, the "Welding fault" output is set or the "Timer
ready" output is removed if there was a general error.
• If a sequence has not reached the current time (e.g. due to activated
sequence lock), the WC is not set.
• In this case, if a start is pending, the WC is set by "Reset fault with WC" until
the start is reset.
• The system reports that at least one of the applied electrodes must be start
dressed, (depending on the setting of the electrode parameter "Dressing new
electrode" this message is activated or deactivated in the individual
electrodes).
• After setting the input "Query tip state", the inputs of the spot selection are
interpreted as electrode number.
• The status of the individual electrode is then set on the status outputs.
Changes of the electrode number must be confirmed with a positive edge on
input "New data for spot selection".
• This is followed by the status outputs of the electrode number.
• The system reports that at least one of the applied electrodes must be
dressed.
• After setting the "Query tip state" input, the inputs of the point selection are
interpreted as electrode number.
• The status of the single electrode is then set on the status outputs. Changes of
the electrode number must be confirmed with a positive edge on input "New
data for spot selection".
• This is followed by the status outputs of the electrode number.
With this pre-warning, the system reports that the maximum electrode life of the
active servo gun will soon be reached.
• The system reports that the level of at least one of the applied electrodes will
soon be reached or has been reached.
• After setting the "Query tip state" input, the inputs of the spot selection are
interpreted as electrode number.
• The status of the single electrode is then set on the status outputs. Changes of
the electrode number must be confirmed with a positive edge on input "New
data for spot selection".
• This is followed by the status outputs of the electrode number.
• The system reports that the level of at least one of the applied electrodes has
been reached.
• After setting the "Query tip state" input, the inputs of the spot selection are
interpreted as electrode number.
• The status of the individual electrode is then set on the status outputs.
Changes of the electrode number must be confirmed with a positive edge on
input "New data for spot selection".
• This is followed by the status outputs of the electrode number.
• The system reports that the timer part of the system is ready and does not
report any errors.
• This signal does not include the status of the servo gun, which may be in a
