Specification
Mounting method as confirmed by shipyard (top or side)
Mounting size: As confirmed by shipyard (JIS or DIN, others)

Flange SS41, SUS304, SUS 316L
Sensor Pipe SUS 304, SUS 316L
Operating Principle
Level switches of the KD30 series have reed
switches mounted within a sealed tube inserted
via the top of the storage tank.
One or more float assemblies are arranged on the
sealed tube and contain a magnet which operates
the reed switch in the event that the liquid level
rises (high aklarm) or falls (low alarm) past the
level of the reed switch
Testing
Ensure the system is connected to the correct
power source
Check the float level switch operates (contacts
close) by lifting the lest lever (high level) or by
pushing sown lthe lever (low level)
When the sensors have been tested ensure the
test levers are set back to their normal positions
Fault finding if installed
Is the liquid already at alarm level?
Is the power connected and working?
Check operation with the test lever
Installation
Check instrument for any duty tags to confirm the
switch is being installed at the correct location
and as intended for either high (make on rise) or
low (make on fall)
Ensure the switch test levers are set in their normal operational position
When installing the float level switch in the tank take care not to damage the floats or sensor pipe.
