Input "Weld Contactor Enable"
Output "Contactor open"
The Weld Contactor Output will be set with the receipt of a program start (internal
or external), if serial Input "Weld Contactor Enable" is high and ignition is set.
Output "Close Weld Contactor" will stay energized until serial Input "Weld
Contactor Enable" is set low, or a fault occurs, or E-Stop occurs, or a timeout
occurs.
A Timeout is defined as a period of time with no receipt of a "Start" signal. The
timeout is set for 60 seconds.
This input must be maintained high to allow Weld Contactor control logic to
function. The input may be used to open the Weld Contactor as necessary, i.e.
Tip Replacement. If this input is low during the receipt of a program start (with
ignition), an error message ("No weld contactor enable") is displayed.
This output is the inverted signal of input "Weld contactor feedback".
