1 INTRODUCTION

Thank you for selecting an Alpha COND 500 2-Wire Transmitter. This isolated output 4-20mA transmitter is a sturdy microprocessor-based instrument that measures conductivity and temperature and transmits its output via the 2-wire power supply loop.

This transmitter has many user-friendly features – all of which are completely accessible through the water-resistant membrane keypad. Your transmitter includes an instruction manual and a warranty card.

Please read this manual thoroughly before operating your transmitter.

2-wire Conductivity Transmitter

2 PREPARATION

Remove screws from the four corners at the back of the Transmitter, and remove back cover.

Connectors should be exposed as follows:

Figure 1 – Connection Guide

All wiring is done on 2 detachable connectors: –

1.9-pin connector (located on SL1 position) for Conductivity electrode and temperature sensor; &

2.3-pin connector (located on SL2 position) for power supply.

Using a suitable screwdriver, loosen screws from top of connector.

When inserting the wires, always hold connector with top screws facing up.

2.1Power Supply Requirements (SL2 Position)

The Alpha COND 500 transmitter requires a 12 to 24V DC power supply. Other Transmitters and/or a chart recorder may be connected in the loop.

1.Insert positive loop wire from power supply to pin 1, tighten screw.

2.Insert negative loop wire to pin 2, tighten screw. This wire may be linked to a chart recorder or to negative terminal of power supply.

2.2Connecting the Electrode and Temperature Sensor (SL1 Position)

2.2.1To connect the Conductivity electrode:

The Alpha COND 500 transmitter accepts any industrial electrodes for conductivity measurements and they are usually offered with bare wires.

1.Insert the electrode’s conductivity wire Low into pin 3 of SL1 connector. Tighten the screw.

2.Insert the electrode’s conductivity wire High into pin 4 of SL1 connector. Tighten the screw.

2.2.2To connect ATC temperature sensor:

For Automatic Temperature Compensated (ATC) Conductivity readings, an in-built temperature sensor is usually integrated in the industrial conductivity electrodes. Otherwise, a separate 100Ω Pt RTD temperature probe can be used.

3 wire temperature sensor

1.Insert the Pt100 input wire to pin 5 of SL1 connector. Tighten the screw.

2.Insert the Pt100 sense wire to pin 6 of SL1 connector. Tighten the screw.

3.Insert the Pt100 return wire and the shield wire to pin 7 of SL1 connector. Tighten the screw.

2 wire temperature sensor

1.Take a small length of wire and short pins 5 and 6 of SL1 connector. Insert Pt 100 sense wire into pin 6 of SL1 connector and tighten the screws.

2.Insert Pt 100 return wire and the shield wire to pin 7 of SL1 connector. Tighten the screw.

IMPORTANT: It is necessary to connect the SHIELD wire to the pin 7 as stated above to eliminate possible oscillation of the conductivity and/or temperature reading due to electrical noise or interference.

Ensure that no bare wires are exposed and all screws are tightened for proper contact.
