SMARTPro 8968 Introduction Section 1.0 1.1 General Description The SMARTPro 8968 is HART© compatible Microcontroller based two wire transmitter. It takes inputs from Polarographic /Amperometric type of Dissolved Oxygen sensor and transmits it in terms of 4-20mA HART© output. This transmitter is capable of measuring DO and temperature. Thus DO sensor in combination with inbuilt temperature sensor is used for measurement. The measurement results are displayed on LCD display.

For DO, automatic temperature compensation through NTC sensor is provided The transmitter has rugged, weatherproof housing. The enclosure meets IP67 Protection. The output of this transmitter is fully scalable over the total range of sensor. During fault conditions the output can be programmed for 3.55mA or 22mA as per need.

SMARTPro 8968 Installation Section 2.0 2.3 Location and Mounting

For best results install the transmitter in area where temperature extremes, vibrations, electromagnetic and Radio frequency interference are at its minimum.

Use Weatherproof cable glands to keep the water, oil and moisture entering inside the transmitter.

Mount the transmitter as near to the sensor as possible so as to keep the sensor cable length minimum.

With help of the U Clamp provided, mount the transmitter on 50mm OD pipe.

Ensure that the transmitter and the mounting bracket are held properly on the pipe.

SMARTPro 8968 Installation Section 2.0 2.4 Cabling

Supply cable wires should be clearly marked/color coded for +24V and ground to avoid polarity reversal

If conduit is used, Ensure the conduit end is properly terminated in cable gland on transmitter side.

The cable used for 24V supply to transmitter should be routed through cable gland

The Supply cable should be routed away from the Power cabling.

8 Use proper size of lug suitable for 0.5 to 1 sq mm wire with length of 0.6-0.8 mm for terminations on transmitter side.

2.5 Power Supply requirements

The SMARTPro 8968 works on wide range of supply voltage from 12VDC to 36VDC.

The supply voltage at the transmitter input terminals must be at least 12VDC.

The power supply should be capable of taking the loads (minimum 250 Ohms for HART©) and the cable resistance.

For HART© communication the minimum load resistance of 250 Ohms is a must. To supply 12VDC at Transmitter end the power supply voltage must be at least 17.5VDC

The power supply should be capable of supplying the surge current at start up.

SMARTPro 8968 Installation Section 2.0 2.7 Power Supply wiring

Remove the rear cover for wiring of power supply as shown in section 2.6

Use 2 core shielded cable. Terminate the wires at power supply side. Connect the cable shield to earth point at supply side.

Measure the supply at the transmitter side with the help of multimeter. It should be within 12VDC to 36VDC. (Refer section 2.5 for more details)

Mark, color code, Ferrule the wires with +ve and gnd.

Switch OFF the supply before connecting it to transmitter.

Route the cable through conduit to avoid mechanical damages to cable.

Route this cable through a cable gland provided on the transmitter.

Tighten the cable gland nuts tightly so that cables are hold firmly by the rubber seal. This is necessary to prevent ingress of dust and moisture.

SMARTPro 8968 Installation Section 2.0 2.8 Power Supply wiring precautions

Please follow the transmitter grounding guidelines as shown in the diagram

1. Use 2 core shielded wire.

2. Ground the shield at the power supply point.

3. Do not run signal wire nearby high voltage wire.

4. Use separate cable trays and conduits for signal and power cables.

5. Keep power supply and signals wire at least 2m away from motor cable, VFD cables and heavy electrical cables.


SMARTPro 8968 Installation Section 2.0 2.9 Open Collector contacts wiring (Optional)

You have already removed the rear cover as shown in section 2.6

Use 2 core cable with each core 0.5 sq mm. Do the relay wiring on the panel side/Control side.

Measure the voltage at the transmitter end of the cable, With help of multimeter. It should be within 12VDC to 24VDC.

Mark, color code, Ferrule the wires with +ve and gnd.

Switch OFF the Relay supply before connecting it to transmitter.

Route the cable through conduit to avoid mechanical damages to cable.

Route this cable through a cable gland provided on the transmitter.

Tighten the cable gland nuts tightly so that cables are hold firmly by the rubber seal. This is necessary to prevent ingress of dust and moisture.
