1. Settings in the area of the test/disconnected
position:
• Move the withdrawable part out of the test/
disconnected position towards the service
position with a few turns of the crank.
• Slowly move the withdrawable part back to
the stop.
Auxiliary switch S8 must then switch over just
before the stop is reached.
• Slowly insert the withdrawable part from the
test/disconnected
service position until auxiliary switch S8 just
operates.
In this position, it must still just be possible to
move closing push rod 13.2.1. For this test,
the function of the blocking magnet Y0 must
be deactivated manually.
This condition ensures that the electrical
interlock takes effect before the mechanical
interlock in the motion sequence involved.
2. Settings in the area of the service position:
• Move the withdrawable part out of the limit
position towards
position with a few turns of the crank.
• Slowly move the withdrawable part forwards
again to the stop.
Auxiliary switch S9 must then switch over just
before the stop is reached.
7.5.4 Checking the direction of rotation of the travel
motors on motor-driven withdrawable parts
• Move the withdrawable part by hand into a
central position between the test/disconnected
position and the service position.
• Remove the hand crank.
• Switch the auxiliary voltage for the travel motor
on.
• Use the local electrical controls to check that the
withdrawable part moves in the correct
direction.
Caution:
Do not allow the withdrawable part to run up
against a block when the travel direction is
incorrect! Switch the motor voltage off immediately
(the travel process functions electrically by a seal-in
system with limit position switch-off).
There may be a danger of injury when the door is
open!
7.5.5 Testing of interlock conditions
(Figures 3/8, 3/21, 6/5 to 6/7, 7/6 and 7/7)
1. The withdrawable part must only be movable
from the test/disconnected position into the
service position when the circuit-breaker is open
and the earthing switch is open.

position towards the
the test/disconnected
Check the following conditions individually:
• With the circuit-breaker closed, insertion of the
withdrawable part towards the service position
must be blocked after only half a turn of the
crank in the clockwise direction, and the travel
motor on motor-operated withdrawable parts
must not be capable of being switched on.
• With the earthing switch closed, insertion of
the withdrawable part towards the service
position must be blocked after only two
clockwise turns of the crank, and the travel
motor on motor-operated parts must not be
capable of being switched on.
Use no force!
2. The withdrawable part must only be movable from
the service position into the test/disconnected
position with the circuit-breaker open.
Check this condition as follows:
• With the circuit-breaker closed, withdrawal
movement of the withdrawable part must be
blocked after only half a turn of the crank in
anti-clockwise direction, and the travel motor
on motor-operated withdrawable parts must
not be capable of being switched on.
3. Closing of the circuit-breaker must only be
possible when the withdrawable part is in the
defined test/disconnected position or service
position.
The control wiring plug 10.2 must previously
have been inserted.
Check this condition as follows:
• It must not be possible to close the circuit-
breaker with the withdrawable part in any
position between
position and the service position.
Enabling of switching when the withdrawable
part moves into the service position is effected
electrically by operation of auxiliary switch S9
in the withdrawable assembly, and mecha-
nically slightly earlier; the latter corresponds to
a position approximately half a turn of the
crank before stop.
• For motion into
position, the same enabling conditions apply
analogously, in this case by means of auxiliary
switch S8 in the withdrawably assembly.
4. It must only be possible to open the circuit-
breaker (manually) when the withdrawable part is
in the service position or test/disconnected
position and the control voltage has failed.
Check this condition.
5. Withdrawable parts with order-related blocking
magnet Y0 may not be moved in case of control
voltage failure, or when there is no control voltage.
Do not forcibly move blocked withdrawable
parts! The blocking magnet Y0 is only present on
manually operated withdrawable parts.
