ALLOWABLE SETPOINT DEVIATION

Allowable setpoint deviation lets you customize the MDXII unit's out-of-setpoint function.
If you specify a non-zero value for the out-of-setpoint timer, you can set an allowable
deviation of 1 to 99% for that setpoint; entering an out-of-setpoint value of zero disables this
feature. Enter a percentage that the MDXII unit can be out of setpoint before it starts the out-
of-setpoint timer.
You can set the allowable setpoint deviation from the control panel or through the serial port.

Steps and Recipes

This manual defines a process step as a ramp/run combination or simply as a run time.
A recipe can have up to five steps. Once you program a recipe, you can run that sequence of
steps any time. You can program a recipe from the control panel or through the serial port.
To program each step, you set:
• A ramp time, if the process requires one (see page 5-2)
• A setpoint level for the output in kilowatts, volts, or amperes (see page 5-3)
• A run time (see page 5-2)
• The method of output regulation, if necessary (see page 5-1)
Once a programmed recipe is running, modifications to the ramp or run timers, output
setpoint, or method of regulation for the active ramp/run sequence have no immediate effect.
However, any change you make to one of these parameters is accepted and stored for future
use.
Also, you can modify ramp/run sequences that occur later in the recipe. That is, if step 2 is
running, you can modify the parameters for steps 3 to 5; and the new parameters, rather than
the original parameters, are used.
You can program a recipe from the control panel or through the serial port.
To "disable" a recipe, simply set the number of steps to zero (see page 5-3) by pressing the
MODIFY knob from within the TIMERS menu on the control panel or using commands
through the serial port.

TARGET CONTROLS

Target control functions let you choose an operating target, set the length of life for the target,
and monitor target life left while the process is running.
All target control functions are available from the control panel, through the serial port, and
through the User port, except you cannot set target life through the User port.
The target life value is entered and displayed in kilowatt-hours. Enter a value in 10 kWh
increments. The maximum target life setting is 15,000 kWh for an MDXII 15k unit and
30,000 kWh for an MDXII 30k unit. If the end of the target life is reached, the message
"EOTL" (end of target life) displays on the control panel, but output does not shut off. The
