Page 7: Introduction
The purpose of this manual is to provide support for “Qualified personal” as described on the next page, when installing, main- taining and servicing the ATEX sensors of the LDS 6 laser gas ana- lyzer. This manual describes the preparations, installation, main- tenance, service of the ATEX sensors and the barrier units. - Page 8 Therefore only qualified personnel may install or maintain the LDS 6 and the associated ATEX equipment. Persons considered as qualified according to the safety informa-...

Page 9: Installation Guidelines
The chapter begins with some safety information, which is followed by installation instructions. Figure 2.1 below shows a schematic illustration of the set-up. Figure 2.1 The set-up of the LDS 6 and the ATEX sensor system Safety Information Electrical Safety... - Page 10 Laser Safety All lasers used by LDS 6 are of class 1. The emitted laser light is in most cases invisible (near infrared) and the intensity is so low that the unprotected eye is not damaged. However, if you look directly into the beam with focusing optics (such as binoculars) there is a risk of eye damage.

This cable is connected to the bottom of the barrier box when delivered (when an ATEX version of the LDS 6 is used). 2. Connect the hybrid cable to the central unit using the stan- dard procedure. -
Page 24: Instruction: Connecting Receiver To Transmitter Sensor
Installation Guidelines Connecting Receiver to Transmitter Sensor For ATEX versions of the LDS 6 the receiver sensor are pre- mounted with special ATEX electronics and surge protection. The green phoenix contact mounted on the sensor card is already connected with a red wire for + and a black wire for –. Two addi- tional wires should be connected to the phoenix connector. -
Page 25: Purging
Ex sensor must be used. Purging with oxygen free gas is also necessary when performing water vapor mea- surements. The sensors for sensor purging supplied by Siemens Laser Analytics include a needle valve and a check valve (see fig- ure 2.7). -
Page 26: Instruction: Purging Set-Up
Make sure all plugs and tube fittings are sealed with the enclosed pipe thread Sealant (Swagelok MS-PTS-6). (Instructions given on the sealant tube must be carefully followed). NOTE When using a plastic tube, be sure to use the rigid metal insert. ATEX manual for LDS 6 A5E01206710-02... -

1 to 12 months. When performing maintenance and service on the LDS 6 it is of upmost importance that all equip- ment and personnel are ESD protected. The chapter begins with a description of ESD and ESD protection. - Page 28 In many facilities, people are one of the prime generators of static electricity. Therefore, wrist straps must be used while car- rying out maintenance and service on the LDS 6, to keep the per- son wearing it connected to ground potential. A wrist strap con- sists of the cuff that goes around the person's wrist and the ground cord that connects the cuff to the common point ground.
