2. Safety notes and warnings
The manufacturer is not liable for damages which are caused as a result of failure to observe safety notes
and warnings.
•
Burn hazard! Work on hot magnetic level indicators can lead to bodily injuries and burns. The
surfaces of the float chambers and the process connections can become hot. Let the tank cool
down to ambient temperature prior to carrying out any work on the magnetic level indicator.
Wear appropriate PPE (gloves, face protection, possibly respiratory protection equipment).
Keep sufficient distance during operation.
•
The magnetic level indicator and thus also the transmitter can unnoticeably become
inoperative by a blocking of the float. Should you be unsure about the liquid level indicated
another method should be used to check the magnetic level indicator.
•
Should you suspect a defective function or should you find such defective function, it must be
remedied.
•
Only use the magnetic level indicator and the transmitter, once you have read and understood
the complete instruction manual.
•
The present instruction manual must also be accessible for later users.
•
Keep magnetic and magnetisable parts (magnets, construction steel, steel wire or clamps etc.)
away from the magnetic level indicator or accessories such as the transmitter. This also
applies to strong electromagnetic fields (transformers, welding equipment etc.), as both can
interfere with the magnetic force of the magnets contained in the magnetic level indicator or the
transmitter and can lead to malfunctions or failures of the indicator or the accessory parts
(switch, transmitter, measuring converter) attached.
•
Replace damaged or faulty components with original spare parts.
•
Solvents can blunt the plastic components used or can cause cracks. Clean the devices with
soap and water or a plastic cleaner.
