CHAPTER 1INTRODUCTION

1.1 Application

1.3 Note

1.4 Ordeing Informations

1.5 Typical Application with a Junior or a Senior Gauge

When used in conjunction with a Rochester junior or senior Hall Effect transmitter (6320S*207*E) or a Rochester Magnetel Voltage Transmitter (6323S*0071*), this unit will convert the transmitter’s signal into a 4-20mA signal proportional to the liquid level in cylindrical horizontal tank. This converter includes a 24Vdc power supply for the 4-20mA loop.

1.2 Description and Features

- Plastic housing W=100mm, H=76mm & D=58mm for Din Rail mounting- Connections on screw terminals for maximum 4mm² cable- Power supply : 230Vac / 50 or 60Hz- Current consumption : 50mA max.- Maximum resistance of 4-20mA loop : 250W- Maximum resistance of transmitter loop : ±200W (including line resistance and intrinsically safety barrier resistance)- Fuse protection : Solder Fuse - 250mA Fast - 250V- Zero and Gain adjustment- Temperature range : -20°C to +50°C

When used with junior and senior transmitter for flammable liquid, this converter should be used with intrinsically safety barrier « MTL : 7761ac » for exemple (0146-00075E).This intrinsically safety barrier has 107W (Maximum) of internal resistance.

Receiver model number (6390S00523E).Transmitter type : junior or senior Hall Effect transmitter or Magnetel voltage (0-10V) transmitter.

1.7 Calibration of the 4-20mA Output to the Actual 4-20mA Loop

1.8 Transmitter Electrical Wiring

1.6 General Information

To calibrate the 4-20mA signal to the actual 4-20mA loop, proceed as follows :1. Set transmitter on 50%. Turn the potentiometer of 50% adjustment until receiver indicates 50% (clockwise

to decrease and counter clockwise to increase).2. Set transmitter on 10% and adjust receiver to 10% with potentiometer Z (Zero fine adjustement).3. Set transmitter on 90% and adjust receiver to 90% with potentiometer G (Gain fine adjustement).

Note : The “G” and the “Z” potentiometer allow only a fine adjustement of ±3%.

In order to realize correct wiring this documentation should be compared with the one that has been supplied with the transmitter. As a standard our transmitters are supplied with a shielded cable of 2m long LiYCY-OB type with 3 wires of the size (0.75mm²). The transmitter connection to the receiver has to be done with the same type of cable by means of a junction box (not supplied).

For a Magnetel Transmitter (6323S*0071*) : The cable shield is wired to the technical box. The white wire is the positive (Hi) one, the brown wire is the GND (Lo) one, the green wire is the signal (Wi) one (refer to the specific documentation). For this type of transmitter the junction box must be an explosion proof type.

For a Hall Effect Transmitter (6320S*207*E) : The white wire is the positive (Hi) one, the brown wire is the GND one, the green wire is the signal (S) one (refer to the specific documentation).
