Note: These functions require certain inputs. Before
programming these functions, check the packet of drawings that
came with your control for I/O availability.

These functions tell the control to check the status of an
input. They wait either indefinitely for an input to be active,
or wait for only a specified number of cycles for the input to
be active.
If the input does not become active within the specified
delay, the processor generates the appropriate fault
condition, as listed below. (The wait functions with no
programmable delay will abort the schedule and generate the
fault if the initiate is removed while the weld processor is
waiting.)
• Functions #65 and #66: WELD PROCEED fault. Function
#65 will wait in the sequence for up to the specified
number of cycles, nnn for a given input to become either
activated or de-activated. Function #66 waits indefinitely.
Function #65 continues the sequence in No Weld mode to
inhibit weld current from flowing if the Weld Proceed
setup parameter is programmed as a FAULT. If this
parameter is programmed as an ALERT or as NONE, it
continues with the sequence as normal.
• Functions #68 and #69: PRESSURE SWITCH fault.
Function #68 waits in the sequence for up to the specified
number of cycles, nnn. Function #69 waits indefinitely.
Function #68 continues the sequence in No Weld mode to
inhibit weld current from flowing if the Pressure Switch
setup parameter is programmed as a FAULT. If
programming this parameter as an ALERT, it continues
with the sequence as normal.
