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.
