ABB ZS1 Instruction Manual page 62

Releasing the blocking magnet Y0:
• Remove front plate 13.17,
• Disengage blocking magnet Y0 by pulling the
magnet armature,
• While doing so, turn crank 121 about one half
turn (either direction of rotation is permissible).
The blocking magnet is only active in the test
position and service position. In intermediate
positions it has no effect.
6. Disconnection of the control wiring plug 10.2 as
well as later insertion must be blocked in the
withdrawable part's service position.
Check this condition:
7. Operation of the earthing switch must only be
possible when withdrawable part 13 is in the
test/disconnected position or the removed
position (subject to any additional electro-
magnetic interlocks in individual cases!).
Check this condition:
• With the withdrawable part in the test/
disconnected position, it must be possible to
press slide 14.2 in front of the earthing switch
operating shaft 14.1 downwards to the
opening position. The earthing switch can
then be operated.
• With the slide pressed down, it must also be
impossible to start the travel motor on motor-
driven withdrawable parts.
• If the slide is pressed down slightly when the
travel motor is running, the motor must then
automatically switch off immediately.
The selected travel direction is continued by
pressing the button.
It is only possible to press slide 14.2 down
fully with a running travel motor when the
latter is in the start-up phase.
• When the withdrawable part is moved
inwards
pressing down of the slide 14.2 must be
blocked after only one and a half clockwise
turns on the crank.

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 auxiliary switch 11.4 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.

Note:
Check the direction of rotation of the motor
after repair work.
Do not allow the motor to run up against a
block if the direction of rotation is incorrect
