ELECTRICAL PRECAUTIONS DURING USE
Electrical noise generated by switching of inductive
loads can create momentary disruption, erratic display,
latch up, data loss or permanent damage to the
instrument.
To reduce noise :
a) Use of snubber circuits across loads as shown above,
is recommended.
b) Use separate shielded wires for inputs.

Operating Instructions
OP723-V03
LOAD CONNECTIONS
1. The service life of the output relays depends on the
switching capacity and switching conditions. Consider
the actual application conditions and use the product
within the rated load and electrical service life.
2. Although the relay output is rated at 5/10 amps it is
always necessary to use an interposing relay or
contactor that will switch the load. This avoids damage to
the controller in the event of a fault short developing on
the power output circuit.
3. Always use a separate fused supply for the “power load
circuit”and do not take this from the live and neutral
terminals supplying power to the controller.
All safety related codifications, symbols and instructions
that appear in this operating manual or on the equipment must
be strictly followed to ensure the safety of the operating
personnel as well as the instrument.
If the equipment is not handled in a manner specified by
the manufacturer it might impair the protection provided by the
equipment.
Read complete instructions prior to installation and
operation of the unit.
WARNING : Risk of electric shock.
WIRING GUIDELINES
1. To prevent the risk of electric shock power supply to the
equipment must be kept OFF while doing the wiring
arrangement. Do not touch the terminals while power is
being supplied.
2. To eliminate electromagnetic interference use short wire
with adequate ratings; twists of the same in equal size shall
be made. For the input and output signal lines, be sure to
use shielded wires and keep them away from each other.
3. Cable used for connection to power source, must have a
2
cross section of 1mm or greater. These wires shall have
insulation capacity made of at least 1.5kV.
4. When extending the thermocouple lead wires, always use
thermocouple compensation wires for wiring. For the RTD
type, use a wiring material with a small lead resistance (5Ω
max per line) and no resistance differentials among three
wires.
5. A better anti-noise effect can be expected by using
standard power supply cable for the instrument.
MAINTENANCE
1. The equipment should be cleaned regularly to avoid
blockage of ventilating parts.
2. Clean the equipment with a clean soft cloth. Do not use
Isopropyl alcohol or any other cleaning agent.
SAFETY PRECAUTIONS
WARNING :
TERMINAL CONNECTIONS
1. When powering up for the first time, disconnect the
output connections.
2. Fuse Protection : The unit is normally supplied without a
power switch and fuses. Make wiring so that the fuse is
placed between the mains power supply switch and the
controller. (2 pole breaker fuse - rating : 275V AC,1A for
electrical circuitry is highly recommended)
3. Since this is a built-in-type equipment (finds place in main
control panel), its output terminals get connected to host
equipment. Such equipment shall also comply with basic
EMI/EMC and other safety requirements like BSEN61326-1
and BSEN 61010 respectively.
4. Thermal dissipation of equipment is met through
ventilation holes provided on chassis of equipment. Such
ventilation holes shall not be obstructed else it can lead to a
safety hazard.
5. The output terminals shall be strictly loaded to the
manufacturer specified values / range.
1. This equipment, being built-in-type, normally becomes a
part of main control panel and in such case the terminals do
not remain accessible to the end user after installation and
Internal wiring.
2. Do not allow pieces of metal, wire clippings, or fine metallic
fillings from installation to enter the product or else it may
lead to a safety hazard that may in turn endanger life or
cause electrical shock to the operator.
3. Circuit breaker or mains switch must be installed between
power source and supply terminals to facilitate power 'ON'
or ‘OFF’ function. However this switch or breaker must be
installed in a convenient position normally accessible to the
operator.
4. Use and store the temperature controller within the
specified ambient temperature and humidity ranges as
mentioned in this manual.
CAUTION
INSTALLATION GUIDELINES
1. Prepare the panel cutout with proper dimensions as shown
above.
2. Fit the unit into the panel with the help of clamp given.
3. The equipment in its installed state must not come in close
proximity to any heating sources, caustic vapors, oils,
steam or other unwanted process by-products.
4. Use the specified size of crimp terminals (M3.5 screws) to
wire the terminal block. Tighten the screws on the terminal
block using the tightening torque within the range of 1.2
N.m.
5. Do not connect anything to unused terminals.
MECHANICAL INSTALLATION
EMC GUIDELINES
1. Use proper input power cables with shortest
connections and twisted type.
2. Layout of connecting cables shall be away from any
internal EMI source.

Use only the correct thermocouple wire or
compensating cable from the probe to instrument
terminals avoiding joints in the cable if possible.
Failure to use the correct wire type will lead to
inaccurate readings.
Ensure that the input sensor connected at the
terminals and the input type set in the temperature
controller configuration are the same.
USER GUIDEUSER GUIDE
1. Display Bias : 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.
2. Filter Time Constant : The input filter is used to filter out
quick changes that occur to the process variable in a
dynamic or quick responding application which causes
erratic control.
The digital filter also aids in controlling processes where
the electrical noise affects the input signal.
Larger the value of FTC entered, greater the filter added
and the slower the controller reacts to the process and
vice versa.
3. Auto tune (AT) : The Auto-tuning function automatically
computes and sets the proportional band (P),
integral time (I), Derivative time (D), ARW% and
cycle time (CY.T) as per process characteristics.
Tune LED blinks at faster rate when auto-tuning is in
progress.
At the completion of Auto-tuning, Tune LED stops
blinking.
If the power goes OFF before auto-tuning is completed,
Auto-tuning will be restarted at next power ON.

Self-tuning is initiated under the following conditions :
1) When setpoint is altered.
2) When tune mode is altered. (TUNE=ST)
ST will start only if PV < 50% of setpoint.
ST will work only when ACT=RE.
6. Self Tune (ST) : It is used where modification of PID
parameters is required repeatedly due to frequent
change in process condition eg. Setpoint.
Tune LED blinks at slower rate when Self-tuning is in
progress.
At the completion of self-tuning, Tune LED stop
blinking.

Set point

5. Manual Reset (for PID control & I = 0) : After some
time the process temperature settles at some point
and there is a difference between the set temperature
& the controlled temperature. This difference can be
removed by setting the manual reset value equal &
opposite to the offset.
!
!
If auto-tuning is not completed after 3-4 cycles, the auto-
tuning 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.
4. 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 ‘ON’ and at which the relay switches
‘OFF’ is the hysteresis or dead band.
