Cold Junction Compensation
This parameter is active if process input is selected TC input.
Cold junction compensation is active.
Cold junction compensation is not active.
Operating Scale Maximum Value
(Scale Low Point, Scale High Point)Unit
Used for Proportional band calculation and display blink.
Scale:
The difference, between high point and low point of the process
input type. Example: If tCSL = 2 (low point is -200, high point is 900),
then scale is 1100. If input type is Voltage/Current, then the scale is
difference between tPoH and tPoLparameters.

then Proportional Band = ( - ) * / 100.0
Proportional Band = (1000-0)*50.0/100.0 = 500 °C
INTEGRAL TIME (0, 3600)Second
Can be changed by the user. After complated the tunning
correctly, integral time value changes automatically. If it is 0,
integral control is deactivated.
DERIVATIVE TIME (0.0, 999.9)Second
Can be changed by the user. After complated the tunning
correctly, integral time value changes automatically. If it is 0,
derivative control is deactivated.

MINIMUM CONTROL OUTPUT (0.0, )%
Even as a result of the PID calculation device calculates the
%output value less than this parameter, heating or cooling
output is active minimum for OLLparameter.
MAXIMUM CONTROL OUTPUT ( , 100.0)%
Even as a result of the PID calculation device calculates the %
output value greater than this parameter, heating or cooling
output is active maximum for OULparameter.
HEATING MINIMUM CONTROL OUTPUT TIME
(0.0, )sec
Heating output can not be active less than this parameter.
Even if this parameter is 0, this parameter is accepted
50 msecs for security.
COOLING PROPORTIONAL BAND COEFFICIENT
(0.0, 100.0)
If heating and cooling PID is used in a system, tune operation is
performed by heating output.Cooling proportional parameter is
calculated with heating proportional band value and coefficient

COOLING
INTEGRAL

It can be changed by the user. When tune operation finishes,
it can be changed by the device. If it is 0, integral control
part does not perform.
COOLING
DERIVATIVE TIME (000.0 sec, 999.9 secs)
It can be changed by the user. When tune operation finishes, it can be
changed by the device. If it is 0, derivative control part does not perform.
When tune operation finishes if this parameter is 0, it can not
be changed because derivative control part does not perform.
COOLING OUTPUT PERIOD TIME (1 sec, 150 secs)
It is control period of cooling output.
COOLING MINIMUM CONTROL OUTPUT

,100.0)%
It is % of cooling minimum output. If heating and cooling PID
control functions operate together, this parameter is not
considered. Even as a result of the cooling PID calculation device
calculates the output value less than this parameter, cooling
output is active minimumor OLLC parameter.
