2 Safety instructions

2.1 Intended application

The COM 223/253 transmitter is a field-tested

and reliable measuring transmitter used to

determine the oxygen concentration of liquid

media.

The transmitter COM 223/253 is particularly

suitable for use in the following areas:

•Sewage treatment plants

•Sewage treatment

•Drinking water

•Water conditioning and monitoring

•Surface water (rivers, lakes, oceans)

•Fish farming

2.2 General safety instructions

This device has been manufactured for safe

operation according to the state of the art in

engineering and conforms to the applicable

regulations and European standards (see

Warning:

•Operating this instrument in any

way other than as described in

these instructions may compro-

mise the safety and function of the

measuring system and is therefore

impermissible.

•The notes and warnings in these

installation and operating instruc-

tions must be strictly adhered to!

2.3 Installation, start-up, operation

Warning:

•This device may only be installed,

connected electrically, commis-

sioned, operated and serviced by

rised by the system operator.

•The personnel must be familiar

with these operating instructions

and must adhere to the

instructions described therein.

•Make sure that the power supply

ratings match the data specified

on the nameplate before you

connect the instrument to a power

source.

•A clearly identified mains

disconnecting device must be

installed close to the instrument.

•Live components can be touched

through the vent slots in the

housing and the openings on the

rear of the housing. Do not insert

any tools, wires or similar objects

into these slits (only COM 223).

•Check that all connections have

been properly made before

powering up the system!

•Damaged equipment that may be

dangerous must not be operated

and should be clearly identified as

being defective.

•Any troubleshooting of the measur-

ing system is to be performed

exclusively by authorised, trained

personnel.

•If faults cannot be remedied, the

instrument must be removed from
