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.

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
(5
Ω
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.
