SETTING THE JOULE THRESHOLD

PROCESS → CONTROL → JOULES → THRESHOLD
This option allows you to set a level of output power that must be met or exceeded before
Joule calculation begins. You can use this feature to improve the accuracy for processes that
have long ignition times.
To set the joule threshold, follow these steps:
1. Press PROCESS → CONTROL → JOULES → THRESHOLD.
2. Rotate the MODIFY knob to select a value between 10 W and maximum unit power
divided by 8.
3. Press ENTER to accept and exit.

Setting the Ramp

Use this option to ramp the output to a process setpoint. This option allows you to enable the
feature, set a ramp start setpoint percentage, and set a ramp time. The ramp time is set in 10 ms
increments. The minimum ramp time is .05 seconds. The maximum ramp time is 600.00
seconds.
Note: If your unit has the 100 ms ramp feature enabled, the range is 0.5 seconds to 6000.0
seconds.
Ramping, recipes, and TCC modes are mutually exclusive. The out-of-setpoint timer is
disabled while output is ramping. The following equation is used to determine if the ramp is
achievable by the processor:
(setpoint - start_setpoint / ramp steps (in 10 ms increments)) = delta_setpoint
The start_setpoint is equal to (truncation)((setpoint * ramp_start_setpoint_percentage) / 100).
Note: Because this calculation does not allow a fractional portion, the ramp will be more
accurate with a greater separation between start and end setpoints.
If you want to allow the ramp, make sure (delta_setpoint * 65535) > 100.
If the ramp is not achievable by the processor, error messages will flash on the display.
However, output will turn on and the output will step directly to the requested setpoint.
Note: In current regulation there are two implied decimal places thus 1000 = 10.00amps.
PROCESS → CONTROL → RAMP
To enable ramp mode, follow these steps:
1. Press PROCESS → CONTROL → RAMP → ENABLE.
2. Rotate the MODIFY knob to select Yes or No to enable or disable ramp mode.
3. Press ENTER to accept and exit.
