Using the Target Conditioning Cycle (TCC)

PROCESS → CONTROL → TCC
The TCC menu lets you enable the TCC (Target Conditioning Cycle) algorithm and
set the TCC "idle" timer. Enabling the TCC algorithm places setpoint and arc
handling under microprocessor control, letting you achieve fast, automated target
conditioning. Before enabling the TCC algorithm, ensure that you have first entered a
setpoint and set values for the arc handling parameters.
When TCC algorithm is enabled and the unit receives an on command, the
microprocessor sets the arc detect time to 20 µs (in "custom" arc handling, the
shutdown time remains unchanged) and initiates a series of trials (or "steps") to reach
your desired setpoint ("the final setpoint"). To begin, the microprocessor sets an initial
setpoint equal to 50% of the final setpoint. After 10 ms, the microprocessor checks the
output level and sets a new interim setpoint equal to 125% of the output level. The
microprocessor continues to check the output level and to set a new interim setpoint
(always 125% of the output level) every 10 ms until the output level is equal to 80% of
the final setpoint. When 80% of the final setpoint is reached, the interim setpoint is set
equal to the final setpoint, the TCC algorithm ends, and arc handling is returned to the
parameters you set up previously.

ENABLING TARGET CONDITIONING CYCLE (TCC)

PROCESS → CONTROL → TCC
This function enables or disables the TCC algorithm.
To enable TCC mode:
1. Press PROCESS → CONTROL → TCC → ENABLE.
2. Rotate the MODIFY knob to select Yes or No to enable or disable TCC mode.
3. Press ENTER to accept and exit.

SETTING THE TARGET CONDITIONING CYCLE (TCC) TIMER

PROCESS → CONTROL → TCC
When TCC is enabled, the TCC algorithm executes automatically the first time the
output is turned on. The TCC timer feature lets you set an acceptable idle time for
subsequent runs. If the output is off for less than the idle time, the TCC algorithm does
not re-initiate upon the next on command. If the output is off for longer than the idle
time, the TCC algorithm executes with the next on command.
Note: If the timer is set to 0 and the TCC algorithm has been enabled, the unit will
initiate the TCC algorithm every time output is turned on.
To enable the TCC timer:
1. Press PROCESS → CONROL → TCC → TIMER.
