Assembly Of A 4700E Or 4800E Positioner On A Valve; Pneumatic Connection Of Positioner 4700 E / 4800 E; Installation And Start Up; Installation - GE 4700E Instruction Manual

6. ASSEMBLY OF A 4700E OR 4800E POSITIONER ON A VALVE

Comply with current national and local regulations for electrical installation work.

Comply with national and local explosive atmosphere regulations.

 Before carrying out any work on the device, power off the instrument or make sure that the local
conditions in the potentially explosive atmosphere permit the safe opening of the cover.
Before switching on or after doing any work on the device, always tighten the cover (C) with a seal (J)

in good condition and put back the safety screw (V).
Note:
Before installation, check that the device is undamaged. In the event of damage, inform the
manufacturer whose address is shown on the serial plate;
If the positioner is supplied mounted on a valve, GE Energy installs it, make the pneumatic connection and
configure and calibrate it.
When the positioner is shipped alone, the user is responsible for its installation, electrical and pneumatic
connections and its calibration.
Please refer to operating instruction manual GEA19730 for more detail.

7. PNEUMATIC CONNECTION OF POSITIONER 4700 E / 4800 E

 Make sure that the air supply pressure is suitable for the installation and for the instrument.
When using a positioner make sure that the air supply pressure matches the one specified on the

serial plate without exceeding 700 kPa (100 psi).
If the instrument has been shipped alone, make pneumatic connections as per § 2.2:
air supply pressure to input (S) and output (O) to the actuator.
Minimum diameter of tubing:
- 4700 E : 4 x 6 mm
- 4800 E : 10 x 12 mm

8. INSTALLATION and START UP

These operations must be put into service in conformance with EN/IEC 60079-17 and / or national and local
regulations applicable for explosive atmospheres.
Before carrying out any work on the device, check that the local conditions in the potentially explosive atmosphere
zone permit the safe opening of the covers.

8.1. Installation

Explosionproof instrument can be installed in flammable gas explosive atmosphere groups IIA, IIB, IIC for the
zones 1 and 2 or in flammable dust explosive atmosphere group IIIC zones 21 and 22.
Intrinsically safe instrument can be installed in flammable gas explosive atmospheres groups IIA, IIB, IIC for the
zones 0, 1 and 2 or in flammable dust explosive atmosphere group IIIC zones 20, 21 and 22.
Note: Since the apparatus has a multiple certifications: ia, d, nA or nL, it is recommended that the type of
installation Ex ia, Ex d, Ex nA nL is identified on or next to the apparatus.

8.2. Start up

NOTE
Before start up, proceed, if required, with instrument calibration as per § 9 and/or ensure that all the safety
:
instructions in the preceding paragraphs have been strictly followed.
Before switching on or after doing any work on the device, always tighten the cover (C) with a seal (J)

in good condition and put back the safety screw (V).
 Check that the cable gland is certified for the intended use and that the electrical data are suitable
for the operating zone.
