Duon System Co.,Ltd.

Chapter 2 Handling Cautions

This chapter consists of cautions for transmitter handling and storage, selection of installation locations,

insulation and explosion structure, etc.

[Quick Reference Manual]

Step Job Job Details Instrument

1 Unpacking - Unpack transmitter packing

Model and

Specifications

Check

- Make sure whether the delivered transmitter is same

as options attached on its nameplate

3 Storage

- Places not exposed to water, non-vibration and non-

impact area

- Ambient temperature 25 deg C and relative humidity

65% RH

Calibration on a

Calibration Room

- Configuration of Range, Zero/Span, Unit, Tag,

Damping Time, Transfer Function, DA Trim and other

parameters

- HHT

- Pressure

Source

(requested)

- Galvanometer

Installation

Locations

- Where ambient temperature is not fluctuated

- Where corrosion happens by chemical materials, etc.

- Where vibration and impact is not severe

- Where non-explosion area is matched on

explosionproof regulations

- Where maintenance is very easy

(Engineering)

Mechanical

Considerations

- Where transmitter can be handled easily

- Be cautious not leaking the pressure.

(Engineering)

Electrical

Considerations

- Connect 24 Vdc

(Power Supply is 11.9 Vdc – 45 Vdc)

- For HART communication, total resistance on

transmitter terminal loop should be 250 – 550 Ohm.

(Engineering)

Mounting and

Installation

- For mounting transmitter, an appropriate bracket

should be used.

- Transmitter should be fixed well against swing.

(Mounting and

Installation)

Calibration on

Spot

- Sensor Zero Trim has to be done after ten seconds,

namely, differential pressure become zero and

stabilized.

- Make sure that PV value of transmitter is zero and

current is 4 mA.

HHT or

Zero/Span

button

10 Pressure

- Do not apply the regulated differential and line

pressure.

- Close equalizing valve of 3 valve manifold, Then,

open stop valve on high and low side slowly and

simultaneously.

(Applying

pressure)

11 Operation - Make sure whether transmitter operates well or not Eye or HHT
