HIGH LIMIT - When this is exceeded, the PPC4000 will proceed to lockout.
The user programs both HIGH MARGINAL and HIGH LIMIT for the temperature or pressure sen-
sors based on the input signal received. The HIGH MARGINAL cannot be set higher than the HIGH
LIMIT nor can either be set lower than the sum of SETPOINT plus CUT OUT. Alarm points for
stack monitoring can be set anywhere within the sensor range.
Both INTEGRAL and DERIVATIVE terms are used to eliminate steady-state error and reduce over-
shoot. They each have a range of 0 to 100%. This value determines how much of the error to factor
in the calculation. A value of 0 turns the function off.
When completed, press the BACK key to get back to the top layer menu at the point of exiting or
press the HOME key to go directly to the home screen.
