9.1.3 QUENCH TEMPER WITH CHAIN MODE
Schedules 03 and 04 are chained together to illustrate "Quench-Temper" operation. Schedule
03 performs the squeeze, weld and quench functions (using "Hold" for Quench), and 04
performs the temper and hold functions (using "Weld" for Temper). Valve output #3 is used.
The weld light gives a visual indication of the relative amplitude and duration of current
during weld and temper times.

9.1.4 UP AND DOWN SLOPE WITH CHAIN MODE
Schedules 05, 06, 07 and 08 are chained together to illustrate up-down slope operation.
Schedule 05 performs the squeeze function and establishes the percent current at which the
up slope will begin (bottom current). Schedule 06 performs the weld function and sets the
up slope time. Schedule 07 sets the downslope time and the % current it starts from.
Schedule 08 establishes the percent current at which the downslope will end, and performs
the hold function. The number in the schedule display will change as the sequence
progresses from one schedule to the next. Valve output #1 is used for this example.
