5.10 Process data monitoring (Phoenix / alpha Q)
On the RINT X12 in combination with welding machines in the Phoenix / alpha Q machine series; there
are 4 output signals available for monitoring the welding process. This provides cost-effective monitoring
options for the most critical process values.
The welding voltage, welding current, wire feed speed and motor current are monitored.
The parameters for the monitoring process are easy to set using the PC300.NET welding parameter
software.
The monitoring process functions for the duration of the welding process in the relevant process main
current phases to avoid errors being detected from transient procedures, which are common at the start
and end of the process.
There is a single tolerance value available for each of the following: welding voltage, welding current, and
wire speed. These can each be used to set a permissible, percentage deviation from the current nominal
value. The motor current is set as an absolute value.
A response speed can be set for each of the two parameters (welding voltage and welding current, or
wire speed and motor current).
Detection is triggered for a single channel when the actual process value exceeds or falls below the
current nominal value across the specified tolerance for the duration of the response time. The RINT X12
issues this message via a corresponding relay output.
A single monitoring channel can be excluded from the monitoring process by assigning the value 0 to the
relevant tolerance value.
