Mounting and start-up
5.1
Movement mounting
The dial must be adequately stable. The mounting drill
hole must have a diameter of 12.3 mm. The movement
must be mounted in a vertical position.
The position of the mounting parts is shown in fig. 1.
The disc nut (2*) M12 x 1 is to be carefully tightened with
a special wrench tool (Art. no. 36761) and a torque
wrench with a torque of 4.5 Nm +/- 0.2 Nm.
Attention:
After tightening of the disc nut (2*), the movement must
not be moved anymore!
5.2
Mounting of hands and start-up
5.2.1
Mounting of hands
The shafts of the hour, minute and second hand are
positioned ex-work on the 12 o'clock position. The hands are
to be fixed and tightened on the shafts without rotating the
shafts. Enough space must be provided between the hands.
See Fig. 2.
For the mounting of the hands, the movement should be
rested on a flat surface. The hands should be mounted
without using too much force. Excessive pressure on the axis
can damage the movement!
The 12 o'clock position must be checked on each movement
after mounting the hands (chap. 5.2.2).
5.2.2
Start-up and checking the hand position
•
Connect time signal
•
Hold down push-button for 5s (12 o'clock position)
Are the hands exactly on the 12 o'clock position?
•
If the hand position is incorrect, carefully loosen the hand, adjust and then tighten
it again (shaft must not be rotated during this).
•
If the hand position is correct, hold down the push-button for 5s again. The clock is
now ready for operation and sets itself.
