ISOLATION CONTACTOR SAVER CSVR
This input tells the weld processor to enable the isolation contactor
delay timer. The delay timer (programmed in the setup parameters,
as described on page 5-13) holds the isolation contactor closed after
a weld schedule is completed, to prevent it from dropping out
between welds.
If this input is active at the end of a schedule, the weld processor
will hold the isolation contactor closed for the amount of time
programmed. For further details, see page 5-13.
If this input is not active, the isolation contactor will drop out at the
end of the weld schedule. However, if this input drops out during
the delay time, the remaining time on the delay timer is aborted and
the isolation contactor is immediately opened.
Setting this input to 0 means the input defaults to open. Setting to 1
means the input defaults to closed.
FAULT RESET Input FR
This input allows the user to remotely reset all faults.
TRANSFORMER OVERTEMP TROT
This input tells the state of the transformer and external cooling
system. It is provided as an external welding transformer over-
temperature switch. If not using this input and it is programmed,
jumper it HIGH.
If this input is not active when the control receives a schedule
initiate, a SYSTEM COOLING fault will be generated, and the NO
FAULT output will be de-energized.
A SYSTEM COOLING fault also occurs if a weld schedule
contains Function #79 (WAIT nnn CY FOR SYSTEM COOLING),
and this input does not become active within the number of cycles
specified.
Setting this input to 0 means the input defaults to open. Setting to 1
means the input defaults to closed.
NO STROKE/NO WELD Input NSNW
When this input is active, the control is in No Stroke/No Weld. This
tells the weld control to cycle without supplying current and
without turning on the valves. This input affects the weld valves
only. It does not affect any other outputs.
Setting this input to 0 means the input defaults to open. Setting to 1
means the input defaults to closed.
