SAFETY PRECAUTIONS

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.

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

WARNING:

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

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

three wires.

have

5. 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.

INSTALLATION GUIDELINES

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.

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

mentioned in this manual.

CAUTION

1. output connections.

2. 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)

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

5. Do not connect anything to unused terminals.

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.

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 amps it is always necessary to use an interposing relay or

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.

LOAD

Electrical noise generated by switching of inductive loads can create momentary disruption, erratic display, latch up, data loss or permanent damage to the instrument.

a) Use of snubber circuits across loads as shown

above, is recommended.

b) Use separate shielded wires for inputs.

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
