Description This setpoint adjusts the maximum allowed positive difference between a
particular cylinder temperature and average cylinder temperature at minimum
power level adjusted by setpoint PminCylDifEval. This setpoint is one of four
setpoints that define the allowed area of cylinder temperature differencies
depending on gen-set power. See the picture below.

LLOWED AREA OF CYLINDER TEMPERATURE DIFFERENCIES DEPENDING ON GENSET
POWER
If the difference of actual cylinder temperature from the average temperature is out
of the allowed range at one or more cylinders the alarm Wrn CylTemp is issued
after the delay
there is a problem with combustion at the particular cylinders.
N
OTE
Logical analog inputs Cyl temp "n" must be configured onto the appropriate
physical analog inputs where the cylinder temperature sensors are connected. Use
the "Cylinder temperature configuration wizard" in GenConfig - Analog inputs tab
for easy configuration of cylinder temperature sensors.

The cylinder temperature difference protection is available in IS-NT only.
