USER MANUAL
GENERAL SERIES
TEMPERATURE CONTROLLER

Safty Instructions
These instrument are meant for temperature control applications. It is advisesable to read the user manual before
installation of the unit. All safety related instructions in this manual should be strictly observed to ensure the safety of
operating personnel as well as the instrument.

The instrument must be configured correctly for intended operation. Incorrect configuration may damage the
instrument or the process under control or it may lead to personnel injury.

Warning
Dangerous voltages are present in this instrument. Before installation or begining of any trouble-shooting procedure
the power to the instrument must be switched off. Instrument suspected of being faulty must be disconnected &
removed to a properly equipped workshop for testing & repair.

To minimize the possibility of hazards like fire or shock,don't expose this instrument to excessive humidity or water.

Avoid using this instrument in areas subject to hazardous conditions like excessive vibration,dirt,excessive humidity
corrosive gases & oils etc. The average ambient conditions should not exceed the maximum ratings specified in
Technical Details section.
.
Unpacking
Upon receipt of the shipment remove the instrument from the carton & check for the instrument,mounting clamps,User
mannual. Inspect the instrument for shipping damages.In case of damage report it to your nearest dealer & shipping
agency for the claim.Write down the model no. Serial no. for future referance when corrosponding with our service
department.

Installation
The controller in its installed state in panel must not come in close proximity to any corrosive or combustible gases,
caustic vapors, oil, steam or any other process by-product.

The controller in its installed state should not be exposed to carbon dust, salty air, direct sunlight or radiant heat leading
to ambient temperature more than 55 0 C.

Ambient temperature and relative humidity surrounding the controller should not be exceed the limits specified.

The controller in its installed state must be protected against excessive electrostatic and electromagnetic interferences

Mounting
The instrument has been designed for panel mounting to afford ease in installation & inspection.

a) Cut the panel according to the illustration as shown. Then insert a series EAP control unit through the cutout into the
panel ( the panel mounting template shown, will assist panel cutting.)

b) Securely tighten the screws of the mounting clamp with a screw driver. Do not fully tighten one screw but do it
alternatly till the controller front panel is fitted snugly in the cutout.

Control unit is now mounted on panel.

Wiring
a) Before wiring, verify the lable for correct model no. & options. Switch off the power while checking.

b) Care must be taken to ensure that maximum voltage ratings specified in Technical deatails section are not
exceeded.

c) It is always recomonded that the power to the instrument be protected by fuses or circuit braker rated at the
minimum value possible.

d) The instrument must be installed inside a suitably grounded metal enclosure to prevent the live parts being accesible
to human hands & metal tools.

e) All wiring must conform to appropriate standards & regulations. Wiring must be suitable for voltage, current &
temperature ratings of the system.

f) Crimped terminal lugs are recomonded for power & sensor connections.

g)Take care not to over tighten the terminal screws.

h) Unused terminals should not be used as jumper points as they may be internally connected causing damage to the
instrument.

i) Verify that the ratings of the output relays & outputs are not exceeded.

j) Electric power in indusrial environments contains a certain amount of noise in the form of transient voltages & spikes.
The electrical noise can enter & adversaly affect the operation of the instrument to some certain extent. For this
reason it is recomonded that the use of shielded thermocouple extension wire which connects from the sensor to the
controller.

Power Supply Wiring
These controllerare supplied to operate at 90 - 270 VAC. Check that installation voltage corresponds with the
power rating.

Local requirements regarding electrical installation should be rigidly observed. Consideration should be given to
prevent from unauthorised person access to the power terminals

Input Wiring
Thermocouple and RTD wiring
For thermocouple input connections the correct type of thermocouple lead wire extension or proper compensating
cable must be used for entire distance between the thermocouple and the instrument, ensuring that the correct
polarity is observed throughout. Joints in cable must be avoided. If the length of thermocouple plus extension wire
is too long it may affect the measurement value. A 100 ohms lead resistance induce an error of about 2 0 C.

For RTD connections the single end leg wire(generally RED) is connected to terminal no. 1 while other two ends
are connected to terminals 2 & 3 respectivly. The three wire leg offers the capability of lead resistance
compensation provided that three leads should be of same length and gauge. For two wire RTD terminals 2 and 3
must be shorted.

Description of Operation
When mounting and wiring are complete unit is ready to turn on. Turn on the power supply. Display will show the current
process temperature. Press the selector switch/key, now it will show the set value. By means of set screw, set it to
desired value. For EAP series instrument again press the selector switch, process temperature will be on the display.

Now if wiring is done in relay energised mode the relay will be in energised state and the LED will be ON. Now process
temperature starts increasing, when it crosses the set value the relay will be off, disconnecting external electrical
circuit.The relay- on LED will go off. There are only two states that is relay on and relay off . Due to heat mass of the
system the temperature will go on rising to a certain value and starts decreasing. When it crosses the value about 2 0 C
below the set value, relay again goes on connecting the electrical circuit so that heaters will be on again. The process
temperature drops to a certain minimum value due to heat mass and again starts increasing. The cycle goes on
continuously. The nature of control is of oscillating type.

On--Off Control Action
This type of control action is widely used in industrial processes. There are only two states ON state & OFF state and
no intermidiate step is there. The controlled temperature cycles around the set point as shown in fig. The maximum
temp. above set point is called overshoot while minmum temp. below set point is called undershoot. The degree of
overshoot or undershoot depends upon the system characteristics & not upon the controller. It generally
depends upon sensor response time, time lag, capacity of heating systems, total heat mass of the systems etc.. When
heat mass of system >> than the heat mass of heating system, on-off controller shows good results with minimum

Sensor Placement
Proper sensor placement can eliminate many problems in a control systems. The sensor should be placed so that it can
detect any temperature change with minimum thermal lag. The sensor tip is the sensing element in the system & must
be in direct contact with the process material to provide optimum sensing accuracy. One inch immersion is usually
satisfactory for either liquid or solid applications.

In a process that requires fairly constant heat output,the sensor should be placed close to the heater . In a process
where heat demand is variable, the sensor should be closer to the operating area. Some experimenting with the sensor
location is often required to find the optimum location. In a liquid prosess, the use of stirrer will eliminate the thermal
lag. As thermocouples are point measuring devices placing more than one sensor in parallel will provide an average
temp. reading & produce better results in most processes. Proper sensor type is also a very important factor in
obtaining precise measurements. The sensor must have the correct temp. range to meet the process requirements.
Standard sensor limits of error are +2 degree celcius plus drift caused by improper protection or an over temp.
occurance. This error is far greater than the controller error & can not be corrected at the sensor end except by proper
selection & replacement.

Cautions
As the signals generated by the thermocouples & resistance bulbs are at low levels, complete protection
against induction noise of external origin should be provided.
1 ) Place the thermocouple circuit as wide apart as possible from the power supply circuit. Shielding wires
are recommended.

2 ) Keep the thermocouples at a distance from strong magnetic fields.

3 ) Extend the compensation conductors to the terminals of the
instruments.
