5. The withdrawable part with blocking magnet
Y0 (if ordered) may not be moved if the control
voltage fails or is not avail able. Do not use
force to move the blocked withdrawable part!
Removing the block:
• Remove front plate 50.6 and 50.7
• Release the blocking magnet Y0 by pressing
the armature continuously when moving the
withdrawable part by using the hand crank
146 for 1/2 right or left
• The blocking magnet is effective only in the
service and test/disconnected position and
is not effective in the intermediate position
6. Removal of control wiring plug 10.2 and reinser
tion of the plug must be blocked with the
with drawable part in the service position.
Check this condition.
7. Operation of the earthing switch must only
be possible when withdrawable part 50 is in
the test/disconnected position or the removed
position (subject to any additional
electromagnetic inter locks in individual
cases!).
Check these conditions as follows:
• With the withdrawable part in the test/
disconnected position, it must be possible
to press slide 14.2 in front of the earthing
switch drive shaft 14.1 downwards to the
opening position. The earthing switch can
then be operated
• When the withdrawable part is moved inwards
towards the service position, pressing down
of the slide 14.2 must be blocked after only
one and a half clockwise turns on the crank
7.5 Tests on the switchgear panel
7.5.1 Auxiliary switch setting on the earthing
switch
(Figures 6/8 and 6/9)
1. There must be a run-on of 0.5 mm in the fully
operated position before the plunger reaches
the stop (for safety reasons).
2. Limit position auxiliary switch Q8S2 for
earthing switch ON must be operated
immediately after the dead centre position
of the toggle spring mechanism is reached
in the closing process and the automatic
quick-closing process has started.
3. Limit position auxiliary switch Q8S1 for earthing
switch OFF must be operated on earthing
switches with manual mech anisms during
the opening motion of the slide 14.2 before
half of the hexagon shaft has become visible,
or 1 mm before the tongue of the slide makes
contact with the armature of the unexcited
blocking magnet.
