Operating Manual
Introduction
A proportional–integral–derivative controller (PID controller or three
term controller) is a control loop feedback mechanism widely used in
industrial control systems and a variety of other applications requiring
continuously modulated control. A PID controller continuously
calculates an error value as the difference between a desired
setpoint (SV) and a measured process variable (PV) and applies a
correction based on proportional, integral, and derivative terms
(denoted P, I, and D respectively) which give the controller its name.
Caution for your safety
WIRING: The probe and its corresponding wires should never be
installed in a conduit next to control or power supply lines. The
electrical wiring should be done as shown in the diagram. The
power supply circuit should be connected to a protection switch.
The terminals admit wires of upto 2.5sq mm.
WARNING: Improper wiring may cause irreparable damage and
personal injury. Kindly ensure that wiring is done by qualified
personnel only.
Maintenance: Cleaning: Clean the surface of the controller with a
soft moist cloth. Do not use abrasive detergents, petrol, alcohol or
solvents.

Controller:Controller should be installed in a place
protected by vibration, water and corrosive gasses and
where ambient temperature does not exceed the values
specified in the technical data.
Probe :To give a correct reading, the probe must be installed
in a place protected from thermal influences, which may
affect the temperature to be controlled.

Working
1. Auto tuning
The Auto-tuning function automatically computes and sets the
proportional band (P), Integral time (I), Derivative time (D) as
per process characteristics.
While Auto-tune is in progress "AUTO" led will turn ON.
After Auto-tuning is complete the "AUTO" led will turn OFF.
PID-time proportional
with auto reset & rate
If auto -tuning is not complete after 3-4 cycles, it is suspected to
fail. In this case, check the wiring & parameters such as the
control action, input type etc.
Carry out the auto-tuning again, if there is a change in setpoint
or process parameters.
Note : In Auto Tunning running time, user can not change
the parameter value.
2. ON/OFF control action (For reverse mode)
The relay is 'ON' up to the set temperature and cuts"OFF"
above the set temperature . As the temperature of the system
drops ,the relay is switched 'ON' at a temperature slightly
lower than the set point .
HYSTERESIS:
The difference between the temperature at which relay
switches 'OFF' is the hysteresis or dead band.

Parameter
While changing the sensor type
parameters of level1 will reset accordingly.

3
Function: Sets input correction.
Parameter
In time it may be possible that the display may be offset by a
degree or so.
To compensate for this error, user may need to add or minus the
degrees required to achieve the correct temperature.
Example : The temperature on the display is 28 C, whereas the
O
actual temperature is 30 C. User will have to set the "

Function: Sets the lower limit of PV input.
Parameter
Sets the minimum limit for set point adjustment. It can be set
from minimum specified range of selected sensor to HSV-1

Once set at a particular value, this will not allow the set point
to go below this value.
When changing the setting value and SV < LSV, SV is reset

5
Function: Sets the upper limit of PV input.
Parameter
Sets the maximum limit for set point adjustment. It can be
set from LSV+1 value to maximum specified range of

Once set at a particular value, this will not allow the set point
to go above this value.
When changing the setting value and SV > HSV, SV is reset
as HSV.
6
Function : To set service time.
Parameter
Service Time notify the machine user to carry out the machine
maintenance setted at predefined time or to indicate that, the

Example: If user set Service time to 10 days, then after 10
days of continuous service of machine, the SVC icon on
controller will lit to indicate that service time has been elapsed
or its time to service the machine

Example : With a 20 second cycle time, an on time of 10
seconds and an OFF time of 10 seconds represents a 50
percent power output. The controller will cycle ON and OFF
while within the proportional band.

Function: Sets integration time.
Parameter
Sets the integration time of PID parameter.
Term I accounts for past values of the SV-PV error and
integrates them over time to produce the I term.
Example : If there is a residual SV-PV error after the
application of proportional control, the integral term seeks to
O
eliminate the residual error by adding a control effect due to the
"
historic cumulative value of the error.

Parameter
Sets the differential time of PID parameter.
Term D is a best estimate of the future trend of the SV-PV error,
based on its current rate of change. It is sometimes called
"anticipatory control", as it is effectively seeking to reduce the
effect of the SV-PV error by exerting a control influence
generated by the rate of error change. The more rapid the
change, the greater the controlling or dampening effect.
Setting "0" will turn OFF differential.
