1. General description of movement LMV
The movement LMV is based on a 230V synchronous motor which moves the hands every minute via an
echange gear mechanism.
The movement is driven by 24V reversing impulses from a master clock, which are collected by a special
Device, so-called impuls collector.
The impulse collector includes an impulse controller which based on a cam and a micro switcher controls the
current to the synchronus motor. When the contact points of the switcher are closed the motor starts. The LMV
movement has a minute graded disc which indicates the position of the minute hand. This arrangement enable
setting of correct time.
The hour hand has not this feature and thus the position of the hour hand has to manually calculated and
adjusted.
The version LMV-UV complies to the feature and performance of LMV version with the exception that this
movement only has one shaft for minute drive. This version is used for installations with separate gear for the
hand.

3. Check of motor before mounting of hands
At delivery the device is set to full hour (e.g 12.00). The red arrow (6) then points to 0-mark of the setting
plate (1).
1. Check that the arm of the micro switch (10) is in position shown as 10 B on the sketch above.
- If so, continue to 2.
- If not, (which means (10) is in the same position as 10B on the sketch) carry on as follows:
Turn wheel (2) clockwise or anti -clockwise until the arm of the micro switch enters the notch position 10 B
in the wheel underneath the curve (11).
2. Check that the pin (3) fit straight into the hole (4), which should be positioned straight under the pin (3),
when the P-arm (5) is pressed down. In this position the red arrow (6) should point straight to the 0-mark on
the graded disc. (1)
- If so , continue mounting the hands. ( see p.5.1 below)
- If not adjust as follows:
A. Move the brass wheel (2) slightly anti-clockwise until pin (3) is just over hole (4)
B. Press the P-arm (5) so the pin (3) enters hole (4) and keep it pressed down. This step releases the
synchronous motor.
C. Turn the minute hand drive (9) anti-clockwise until the red arrow (6) points straight to 0-mark on the
setting plate.
D. Release the ‘press down’ of the P-arm.
Proceed to mounting of hands p.5.1 (see below).
4. Mounting of hands.
1. Mount the hour hand on the shaft with it´s needle point aiming straight to 12.
2. Fasten the hour hand carefully.
3. Mount the minute hand on the shaft wit it’s needle point aiming straight to 12.
4. IMPORTANT! There should be some space on the shaft between the minute- and hours hand.
5. Fasten the minute hand carefully.

Mounting of hands version 115014-00 LMV-UV
1. Mount the movement to the gear for the hands.
2. Mount the hand(s) on the shaft with needlepoint(s) aming straight to 12.
3. Fasten the hour hand(s) carefully.
4. Mount the minute hand(s) on the shaft with needlepoint(s) aiming straight to 12.
IMPORTANT! There should be some space on the shaft between the minute- and hours hand.
5. Fasten the minute hand(s) carefully.
5. Installation and test.
1. Connect to 230 VAC via the terminal (8A) and protective earth to terminal (8B). When installed a readily
accessible disconnect device shall be incorporated in the fixed wiring.
2. Connect the impulse wire from the master clock via the plug inclosed in delivery.
3. Check that the movement setting remains on full hour, e.g the red arrow (6) points straight to 0-mark.
4. Connect the plug to the movement at (7).
5. Switch on the mains.
6. Wait for a minute impulse for step forward to odd minute.
7. Now the setting plate (1) should turn one mark anti-clockwise and the hands are moving one minute forward.
- If so, the movement are ready for operation.
- If not, the connection to impulse (7) is wrongly polarized. Adjust as follows:
A. Disconnect mains
B. Tur the connector to impulse around or swap wires in the connector.
C. Check procedure from step 3 above.

6. Resetting / Setting of correct time.
In the example below we describe setting of time to 13:15. starting from the settings actual at delivery, that is
12:00.
Disconnect connection to 230V.
1. Disconnect the wire from masterclock (plug at 7). Observe how the connector is applied.
2. Check that the arm of the micro switch (10) is in the same position as 10 B on the sketch,
-If it does, continue to point 3.
-If not (which means the arm is in position 10 A) carry on as follows:
Turn wheel (2) clockwise or anti-clockwise until the arm of the micro switch enters
the notch, position 10 B in the wheel underneath the curve (11). Check so that the pin (3) has position
straight above the hole (4) . Proceed to p.4 below.
3. Move the brass wheel (2) slightly anti-clockwise until pin (3) is straight over hole (4).
4. Press the P-arm (5) so the pin (3) enters hole (4) and keep it pressed down. This release the synchronous
motor.
5. Check that the arrow (6) points straight to 0-mark on the setting plate (1). If not turn theminute wheel (9)
anti-clockwise until that position.
When the red arrow (6) points at 0 on the setting plate (1) this means that the movement is
set to full hour, (the minute hand pointing at 12 and the hour’s hand pointing at full hour 12).
6. Press the P-arm (5) again.
7. Turn the minute wheel (9) anti-clockwise. In this example first a full turn around, then continue until the
arrow (6) points straight to minute mark 14 on the setting plate (1).
8. Check correct time for synchronisation to master clock.
9. Connect impulse wire (7) from master clock. Note! Apply the connector correct.
10. Connect 230V mains.
11. Wait for the right minute impulse. (In this example for stepping forward to odd minute)
12. When the minute impulse comes from the master clock the setting plate (1) is
moving one mark clockwise and the hands are moving 1 minute forward.
The clock now shows 13:15 and it is synchronised to the master clock.
If the movement does not step forward within this odd minute the connection (7) is wrongly polarized.
Adjust by repeat the procedure from p.1 to p.5 above.
Turn the movement manually to even minute (e.g.16) by turning the minute wheel (9) anti-clockwise.
Release the P-arm (5)
Turn the connection (7) the other way around and repeat procedure from p.9 above.

7. Power failure
In case of power failure, the consequences are as follows:
-The master clock does not distribute any impulses. The impulses are stored in the memory of
the master clock. IMPORTANT!! Impulses are collected for max. 10 hours.
-When power returns the master clock wi11 distribute the stored impulses to the movement by
rapid impulses (15 imp./min.).
-Then the movement begins to forward the hands to correct time.
-It will take some minutes (the time depends on how long the power failure has lasted) until
the movement has reset the hands).
-After the movement has reached correct time it returns to normal operation.
8. Maintenance
Lubrication of the movement must be done minimum once a year.All positions marked in the
pictures on the following pages must be lubricated.
Movement placed in aggressive environment should be lubricated at more frequent intervals, particulary the
bearrings on the shafts and the gear mechanism.
Use high-grade lithium-soap paste, for specification please contact Westerstrand Urfabrik AB.
In case of negligence of maitenance the movement may be damaged or the life cycle considerable reduced.
