Ignition protection
“ec” and “tb”
Do not disconnect the BKS-S_ _ _ connector of the
transducer in explosive areas if it is under voltage! This is
why the following warning label is affixed to transducers
with plug connections.
The connection cable must be routed in a permanent
location and protected against tension and rotary loads
using an additional clamp. Drag chains may not be used.
The open line ends are to be connected outside the
classified zones or inside an approved housing.
The transducer’s IP protection must also be maintained
when unplugged. If dust or water accumulates, a suitable
protective cap must be attached to the connector.
The calibration box is not approved for gas-explosive
areas. As a result, the transducer may not be adjusted in a
potentially explosive atmosphere. The calibration box must
be removed from the installation for operation.
2.6
Connectors and magnets
Permissible connectors and magnets are listed in section
11 “Accessories”.
For transducers with plug connections, only the following
connectors with cables that have been preassembled at
the factory are tested and approved:
– BKS-S 32M-_ _
– BKS-S 33M-_ _
Only the magnet versions listed in section 11 “Accessories”
may be used.
If another connector, cable, or magnet is used, the
operator must ensure compliance with the explosion
protection requirements.
2.7
Maintenance, inspection, repair
The measuring principle used in this transducer is
maintenance-free and wear-free. The operator must
regularly inspect the transducer for signs of damage or
malfunctions in line with the operating conditions and
environmental influences. If any damage or wear is found,
the transducer must be immediately taken out of
operation.
Only service technicians from Balluff GmbH may repair
defective transducers. Intervention in the product by the
operator is not permitted due to safety reasons.
The transducer’s housing may not be opened or loosened!
This is why the following warning label is affixed over a gap
in the housing.
