Safety information for GM700 Ex Cross-Duct and Probe
2.1
Intended use and main instructions for operation
Purpose of the device
The GM700 serves exclusively for emission and process monitoring of gases
in industrial plants.
GM700 measures continuously directly in the gas duct (in-situ).
Work on the device
WARNING
Risk of explosion
Work on the device assumes an Ex free zone at the installation
location otherwise there is an explosion risk.
Ensure the work area is Ex free when working on the device.
DANGER
Risk for system safety through work on the device not described in
these Operating Instructions
Carrying out work on the device not described in these Operating
Instructions or associated documents can lead to unsafe operation of
the measuring system and therefore endanger plant safety.
Only carry out the work on the device described in the associated
Operating Instructions or the associated documents.
DANGER
Risk of explosion through incorrect performance of work described
in these Operating Instructions
Incorrect performance of work in potentially explosive atmospheres
can cause serious injuries to people and damage during operation.
Maintenance and commissioning tasks as well as checks should
●
only be carried out by experienced/trained personnel with
knowledge of the rules and regulations for potentially explosive
atmospheres, especially:
– Ignition protection types
– Installation regulations
– Zone classification
Standards to be applied:
●
– EN/IEC 60079-14, Annex A: Knowledge, skills and competencies
of responsible persons, operatives and designers
– EN/IEC 60079-17: Electrical installations, inspection and
maintenance
– EN/IEC 60079-19: Equipment repair, overhaul and reclamation

Product description
Operation in potentially explosive atmosphere
3G / Zone 2: Connection unit and sender/receiver unit
The GM700 Ex corresponds to the ATEX category (according to
●
2014/34/EC ATEX):
II 3/-G Ex pzc op is [ia] IIC T4 Gc/-
●
Special conditions (X identification)
●
A measuring function for explosion protection is not part of the EC
•
type approval
The Ex identification is on the type plate. Example:
●
SICK
GM700-xxx-EXG (xxx=internal type number)
SN: yyyy yyyyy (serial number)
II 3G
II 3/-G Ex pzc op is [ia] IIC T4 Gc/-
-20 °C ≤ Ta ≤ 55 °C
Explosion protection relating to optical radiation in the measuring
●
channel
The explosion protection relating to optical radiation in the
measuring channel is satisfied in accordance with the temperature
range (-20°... +60 °C) specified by ATX/IECEx. The plant operator
must evaluate Ex atmospheres possibly present for exhaust gas
temperatures exceeding this range separately and take suitable
protective measures!
E
Location of Ex relevant subassemblies, see Chapter "Design and
Function".
Do not remove, add or modify any components to or on the device
unless described and specified in the official manufacturer
information. Otherwise the approval for use in potentially
explosive atmospheres becomes void.
Adhere to the maintenance intervals, see Chapter "Maintenance
plan".
Wait 20 minutes after switching off the main power supply before
opening the enclosure.
2.2.1 Safety functions
GM700 Ex category 3G
Malfunction of pressurized enclosure: An alarm signal is output.
WARNING
Risk of explosion through incorrect parameter settings
Unauthorized changing of parameters can cause an explosion with
fatal consequences.
Never change parameters without authorization.
NOTICE
The operating company is responsible for the evaluation of the alarm
signal. See the Pressurized Enclosure System Manual.
2.3
Mounting
DANGER
Risk of explosion through incorrect installation
Incorrect assessment of the installation location as well as all further
installation work in potentially explosive atmospheres can cause
serious injuries to people and damage during operation.
Installation, commissioning, maintenance and inspection may only
●
be carried out by skilled persons having knowledge of the relevant
rules and regulations for potentially explosive atmospheres,
especially:
– Ignition protection types
– Installation regulations
– Zone classification
Applicable standards (examples):
●
– EN/IEC 60079-14, Annex A: Knowledge, skills and competencies
of responsible persons, operatives and designers
– EN/IEC 60079-17: Electrical installations, inspection and mainte-
nance
– EN/IEC 60079-19: Equipment repair, overhaul and reclamation
Local work safety regulations
●
NOTICE
Hazard when exceeding the temperature classes for hot gas ducts
Temperature class T4 (max. 135 °C), for which the explosion protection
of this device is designed, can be exceeded on hot gas ducts.
Plan appropriate insulation of the duct and the flange during project
planning/assembly.
When necessary, ensure adequate ventilation or cooling.
