DT1 - Heating Hopper Heater Derivative Term
format:
xxxxx (constant)
function(s):
Heating hopper heater PID control loop derivative term. This term makes adjustments to
the heater output that are proportional to the slope of the error over time. The purpose
of this term is to make predictive adjustments to help mitigate overshoots (and
undershoots).
UT1 - Heating Hopper Heater Update Time
format:
xxxyy (seconds / seconds)
function(s):
xxx:
Amount of time between heating hopper heater PID updates when the actual
heating hopper inlet temperature is
above
setpoint.
yy:
Amount of time between heating hopper heater PID updates when the actual
heating hopper inlet temperature is
below
setpoint.
OT1 - Heating Hopper Heater Over-Temp Alarm
format:
xxxyy (seconds / °F or °C)
function(s):
xxx:
Amount of time that the heating hopper inlet air temperature must be above
setpoint before a Heating Hopper Over-Temperature alarm is triggered.
yy:
Number of degrees that the heating hopper inlet air temperature must be above
setpoint before a Heating Hopper Over-Temperature alarm is triggered.
NH1 - Heating Hopper Heater No Heat Alarm
format:
xxxxx (seconds)
function(s):
Maximum amount of time after a heat cycle begins during which one of the following two
conditions must be detected:
1. the temperature must climb 20 degrees
2. the temperature must move at least 20 percent toward the target
If neither condition is met, a “NO HEAT” alarm will be triggered.
SO1 - Heating Hopper Heater Setpoint Offset
format:
xxxyy (seconds / °F or °C)
function(s):
xxx:
Amount of time at the beginning of a heat cycle to temporarily target a
lower
temperature. This is to mitigate the inherent overshoot of a PID loop.
yy:
Difference, in degrees, from the current temperature target and the
temporary temperature target.
