PARAMETER EXPLANATION :
• Temperature Unit :
The temperature unit is selectable between °C and °F. when temperature unit is changed, the temperature ranges will
also be changed according to the present selection of unit. if changed, be sure to check all parameter.
• Resolution :
The resolution is selectable between 1 and 0.1 for TC and RTD inputs whereas it is Selectable between 1, 0.1, 0.01,
0.001 for analog inputs. If changed, be sure to check all parametres.
To scale the controller, two scaling points are necessary.
Each scaling point has a coordinate pair of Display
Values and Input Values. It is recommended that the two
scaling points be at the low and high ends of the input
signal being measured. Process value scaling will be
linear between and continue past the entered points to
the limits of the input range. (Factory settings example
will display 0.0 at 0 mA input and display 9999 at
20.00 mA input.)
• SCALING FOR ANALOG INPUT :
Reverse acting indication can be accomplished by
setting reverse scaling parameter as YES. In this
case referring the above eg. for 0.00 mA input the
display will show 9999 and 20.00 mA input the display
will show 0.0
NOTE : This change will not be visible in the
programming menu.
• SET POINT LIMIT VALUES :
The controller has programmable high and low set point limit values to restrict the setting range of the set point.
Set the limit values so that the temperature set point value cannot be set outside the safe operating area of the
process.
Note : 1. Whenever resolution is changed from 1 to 0.1 SPLL and SPHL is limited to -199 and 999 respectively.
2. #1- Display is with fixed 1° resolution for TC / RTD and as per decimal point selected for analog input.

PARAMETER EXPLANATIONS :
ŸHAND OUTPUT PERCENTAGE :
This parameter can be used when a fixed percentage of output is desired. For eg. if 4-20mA analog output is
being used and the desired output is 12mA,the hand percentage can be programmed as 50%.this will ensure
that the analog output available is fixed 12mA i.e. 50%.
NOTE : if Hand Output % is set as OFF Unit is in Retransmission Mode.
ŸCUSTOM DISPLAY :
User can select any of the default Upper Display contents or can create its own 4 digit customized upper
Display.
ŸANALOG RETRANSMISSION :
In case of analog retransmission only the following parameters will be promoted :
1) A-LO : Analog low scaling.
2) A-HI : Analog high scaling.
3) S.ERR : Sensor error level.
Display is with fixed 1° resolution for TC / RTD and as per decimal point selected for analog input.
ŸSENSOR ERROR LEVEL :
This parameter determines the analog retransmission output level in case sensor failure. For eg : ln case of
4-20mA retransmission output, if the sensor error level is set to High, 20mA will be Available at the output at all
times incase of input sensor failure.
ŸPV BIAS : (DISPLAY OFFSET) This function is used to adjust the PV value in cases where it is necessary for
PV value to agree with another recorder or indicator or when the sensor cannot be Mounted in correct location.
ŸFILTER TIME CONSTANT : The filter is an adaptive digital filter that discriminates between measurement noise
and actual process changes.if the input signal is increasing too greatly due to measurement noise, increse the
filter value.if accurate control is desired,increse the filter time constant whereas if the fastest controller response
is required,decrese the filter time constant.
ŸROUNDING INCREMENT : This feature can be used to round off the display to a higher value than "1" in cases
Where the process input and in turn the display is fluctuating. Rounding selections other than 1 cause the
process value to round to the nearest rounding selected. For Example: A rounding increment value of 5 causes
122 to round to 120 & 123 to round to 125.This parameter is not applicable when the resolution is
0.1(forTC/RTD) Set point values, set point limits, Alarnn values, input scalling values, and Analog scalling
values are not affected by rounding. The rounding increment is for controller Display only and does not
affect(improve or degrade)the control accuracy of the unit.
ŸSTANDBY MODE : This feature is useful during machine wiring. if standby mode is selected as YES, the
Following condition exist :
a. All displays are OFF.
b. All outputs are OFF i.e.OUT1,OUT2,MAN & LED's are OFF.
c. Analog output is limited to the lower range.
d. All front keys are disabled.
e. Access to configuration enabled.
The STND status is preserved on power OFF.
