A dwell timer is used to control a process at a fixed temperature
for a defined period. Once the process reaches the setpoint,
dwell timer starts to count until time out . After the time
completes, control output goes OFF and auxiliary output
energises as an alarm.

After Auto-tuning is complete the
"AUTO"
led will turn OFF.
While Auto-tune is in progress
"AUTO"
led will turn ON.
The Auto-tuning function automatically computes and sets the
proportional band (P), Integral time (I), Derivative time (D) as
per process characteristics.
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 lower than
the set point .
HYSTERESIS:
The difference between the temperature at which relay
switches ‘OFF’ is the hysteresis or dead band.

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

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.
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.

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.
PT244-TX is a two set point PID controller. It is available in touch with
RS-485 communication. Customized iconic display interprets status
easily.
