Safety equipment / protective measures
Danger posed by
electrical equipment
The LT 2/KS1-DK system parts constitute equipment for use in industrial power
installations. Switch off the supply voltage to the mains cables when working on
mains connections or parts that conduct mains voltage. Refit any protection
against electric shock that has been removed before switching on the supply
voltage.
Unskilled use or inexpert handling can result in risks to health or material
damages. Therefore, always observe the relevant safety notes to prevent
damage.
Preventive measures to
improve operational
safety
If the LT 2/KS1-DK is employed as a sensor in combination with closed and open-
loop control systems, the plant operator must ensure that a failure or fault in the
LT 2/KS1-DK cannot result in impermissible damages or dangerous operating
states.
In order to prevent faults that may themselves result in direct or indirect personal
injury or material damages, the plant operator must ensure that:
• The responsible maintenance personnel can be notified at any time and as
quickly as possible
• Maintenance personnel are trained to react appropriately to faults in the
LT 2/KS1-DK and associated system malfunctions
• The faulty equipment is switched off immediately in cases of uncertainty
•
Switching off equipment does not result in direct consequential faults
Avoidance of
consequential damages
In order to prevent faults that may themselves result in direct or indirect personal
injury or material damages, take care to ensure that qualified personnel evaluate
the faults and initiate the appropriate measures.
Protection against
escaping gas from the
gas-bearing duct
The KS1-DK combination probe is mounted directly on the gas-bearing duct by
means of a counter-flange. If the probe is detached, depending on the system -
and particularly in the case of excess pressure - aggressive and/or hot gas may
flow out of the duct and severely harm the health of unprotected operators, if
suitable protective measures have not previously been introduced.
WARNING
In the event of excess pressure and temperatures higher than 200 °C in the gas
duct, gas escapes when the KS1-DK combination probe is removed.
• Switch off the system before opening; if this is not possible, wear protective
clothing and a protective mask.
• Set up warning signs to this effect in the vicinity of the probe mounting point.
• Seal the opening immediately after the work.
