Racking Pump Handle; Drawout Position Indicator - Siemens SBA 800 Information And Instruction Manual

Operating Instructions
Part Two - Manipulating the Moveable Drawout Element

Racking Pump Handle

A low-force pump handle is used to rack the moveable
drawout element. The pump handle is an integral part of the
racking mechanism, eliminating the need for an auxiliary
racking device. If there is any resistance in returning the pump
handle to the stowed position. set the directional shift lever to
the neutral position. The racking pump handle can then be
returned to the stowed position.

Drawout Position Indicator

A color-coded indicator displays the position of the moveable
drawout element: connected (red), test (yellow), and un-
locked (yellow). When the moveable drawout element is
being racked from one position to another position, the
indicator will display the more critical position. The connected
position is defined to be more critical than the test position
and the test position to be more critical than the unlocked
position. This means that when racking the moveable drawout
element from the connected position to the test position, the
indicator will continue to display the connected position until
the moveable drawout element has been racked all the way
to the test position. Conversely. when racking from the test
to the connected position, the indicator will display the
connected position as soon as the SB breaker is moved
toward the connected position. The process is the same
when racking between the test and unlocked positions.
