Extended Warranty
For permanently installed systems, the standard 2-year warranty can be extended in 2-year
increments. This must be ordered less than 6 months after the original LKAT system is
shipped.
2.2
ADDITIONAL MEASURING HEAD DETAIL
LKAT Measuring Heads contain an arrangement of Hall Effect sensor ICs and signal
conditioning electronics. The tubular enclosure is constructed of flame retardant plastic
materials. Insulation from the bus is provided by the homogeneous (sealed) construction of
the head. In the event that the head enclosure components become cracked, the bonding
fails, or the weather-tight seal is broken in any way; a replacement head must be substituted.
The Measuring Head is not designed to be repaired.
The LKAT Measuring Head may be mounted on the bus bar using channels and spring-
loaded clamps. Mounting hardware is supplied with each system. When properly installed,
the mounting hardware maintains the position of the measuring head in the event of
temperature fluctuation and / or bus vibration.
An interconnection cable assembly is integral to each half of the Measuring Head. The
standard length is 33 feet (10 meters). Heads with extra-long interconnection cables are also
available - consult the factory for details. Standard measuring head cable assemblies are
terminated with keyed connectors to ensure correct hookup. The interconnection cables from
the measuring head are identified as “A” and “B”. Connecting head cable “A” to Metering Unit
“B” will not result in damage to the head or electronics, but may degrade the calibration
accuracy of the system.
2.3
ADDITIONAL METERING UNIT DETAIL
The Metering Unit electronics are housed in a NEMA 4X enclosure. The enclosure cover
must remain closed during normal operation. The Metering Unit is rated IP65, which
stipulates the following characteristics:
•
Protection from electrical shock as hazardous voltages are inaccessible
•
Limited ingress of dust into the enclosure
•
Limited ingress of water into the enclosure via dripping, spray, or jets from any direction.
