Power Limit
A high side power limit and low side power limit set the maximum output power
within two ranges
A low side power limit limits the output to a percentage of the maximum output
power while the process temperature or value is below the power limit set point.
The high side power limit limits the output to a percentage of the maximum output
power while the process temperature or value is above the power limit set point.
The low side power limit can be viewed or changed with Low Side Power Limit
(Control Output Group).
The high side power limit can be viewed or changed with High Side Power Limit
(Control Output Group).
The power limit set point can be viewed or changed with Power Limit Set Point
(Control Output Group).
The actual output power can be viewed with Output Power (Control Output
Power Group).
