setup parameters. They apply only to the weld schedule where they
appear. They also take priority over any other limits established.
81
TRANSFORMER TURNS RATIO nnn:1 (nnn=1-256)
This parameter tells the control the turns ratio of the welding
transformer used. This lets the control determine secondary current
during a weld. (Secondary current equals the primary current multiplied
by the turns ratio.)
NOTE:
The function TRANSFORMER TURNS RATIO sets limits that are unique
to a given weld schedule. The new limits override the limits programmed
in the setup parameters. They apply only to the weld schedule where they
appear. They also take priority over any other limits established.
82
LINEAR STEPPER #nn ASSIGNED (0 = OFF)
Function #82 assigns a linear stepper to a weld schedule.
The MedWeld 5000 has 63 independent linear steppers. Linear steppers
have 5 programmable levels (called “steps”) to provide additional
energy. When either function appears in a weld schedule, the
appropriate stepper is advanced (incremented) each time you execute
the weld schedule.
If Function 82 is used in a weld schedule it MUST be the first function
in the schedule.
Valid stepper numbers are 1 – 63. To disable a stepper for a schedule,
assign the stepper as zero (#0).
85
PROCESS WELD FAULTS
This function provides a one-cycle delay in the weld schedule. It asks
the MedWeld 5000 to indicate any faults that may have been generated
so far in the schedule.
88
TURN ON ISOLATION CONTACTOR
The function TURN ON ISOLATION CONTACTOR will first check to
determine if the isolation contactor is already closed, and will pull in the
isolation contactor only if it is open. This is designed to improve the
process speed, bypassing the delay provided to wait for the isolation
contactor to close.
89
TURN OFF ISOLATION CONTACTOR
The function TURN OFF ISOLATION CONTACTOR will first check
to determine if the isolation contactor is closed, and will release the
isolation contactor only if it is open. Stepper Assignment Functions

PROCESS WELD FAULTS
This function provides a one-cycle delay in the weld schedule. It asks
the MedWeld 5000 to indicate any faults that may have been generated
so far in the schedule.
