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.
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.
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.
Maintenance:
Cleaning: Clean the surface of the controller with a
soft moist cloth. Do not use abrasive detergents, petrol, alcohol or
solvents.

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.

Example :
If the (SV-PV) error is large and positive, the
control output will be proportionately large and positive and
vice versa if error is negative.
Term P is proportional to the current value of the SV-PV
error .
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
eliminate the residual error by adding a control effect due to the
historic cumulative value of the error.
Setting "0" will turn OFF integration.
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.

The Auto-tuning function automatically computes and sets the
proportional band (P), Integral time (I), Derivative time (D) as
per process characteristics.
After Auto-tuning is complete the
"AUTO"
led will turn OFF.
While Auto-tune is in progress
"AUTO"
led will turn ON.
Carry out the auto-tuning again, if there is a change in setpoint
or process parameters.
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.

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 .
The difference between the temperature at which relay
switches ‘OFF’ is the hysteresis or dead band.
