Maintenance

5.1

Safety information

For GMS841 (ATEX/ IECEx) and GMS842 (

CSA

US)

Before commencing maintenance work

Purge the sample gas path for 15 minutes with 60 l/h with a dry, neutral gas before
commencing maintenance work.

5.2

Maintenance interval

●

Maintenance interval: 1 year

5.3

Maintenance work on the enclosure

▸

Check all connections for tight seat. Especially check the grounding cable to the cover.

▸

Check the device and the connections for corrosion.

▸

Switch device free from voltage.

▸

Open the device.
Also observe:

“Safety measures before opening the enclosure”, page 11

– Check the inside of the device for contamination.
– Check if the seals are clean and free of damage.
– Check all lines for tight seat.

5.4

Cleaning of the enclosure

WARNING: Observe the safety information

Observe the safety information in Chapter

“Opening the enclosure cover”,

page 11

WARNING: Risk of explosion

▸

Do not carry out work on the device in potentially explosive atmospheres.

▸

Only use tools approved for Ex zones.

WARNING: Endangerment of electrical safety by cleaning the enclosure with
liquids

Cleaning with water or other cleaning liquids can damage the electronics and therefore
compromise safe operation of the device.

▸

Always clean signs and other surfaces only with a damp cloth.

WARNING: Hazardous situation when liquids penetrate the system

If liquids have penetrated the equipment:

▸

Do not touch the device any more.

▸

Shut the device down immediately by disconnecting the main power voltage

at an external station (e.g. pull out the power cable at the socket or switch
off the external power fuse).

▸

Contact the manufacturer’s customer service or other trained skilled

persons able to repair the device.
