LK4 series master controller

• USE

    1、The LK4 series master controller is suitable in exchanges the 50HZ
voltage to 380 volt and the DC voltage to 220 volts electric circuits
in, for automation transmission device in control original part. The
master controller may be direct either after the reduction gear
AND-OPERATION machinery joint but the master controller contact basis
operating mechanism travelling schedule or the corner according to
certainly in turn closed or the separation. (Also may borrow
servomotor to actuate).
   1．1、The master controller basic original part has the cam assembly and the
contact assembly. The cam assembly but becomes by the axis and the
wheel disk combination. The cam drum is composed by two similar
semicircles blocks institute, on each opens has ten holes and a
circular slot, two gaps are 18 . On the cam piece opens has the
slot, may transfer 10 respectively to the set bolt about 30 ', thus
is controlled the cam the contact separation and the closed position
also may along with it adjustment. Because the master controller
contact breaks the arc ability and the organization partial abrasion
resistant limit, the cam drum arc of rotation speed does not have to
surpass 60 revolutions/Minute.
    1．2．Each cam drum affects an electric circuit, the cam drum number is
equal to the controller electricity way. When the master controller
has the many electricity way, then has two groups of cams assemblies,
moving contact assembly and static contact assembly. Meanwhile
according to the need, the master controller cam assembly may parallel
rotate, namely also two groups of cams assemblies revolves, also may
connect revolves, namely the first group of cam assembly and the
second group of cam assembly rotates in turn.
   1．3．May divide into according to the LK4 series master controller outer
covering equipment
   1．3．1Protected type master controller     LK4-0LK-1
   1．3．2Waterproof type master controller    LK4-6
   1．4．According to LK4 series master controller whether decelerates may
divide into two kinds:
   1．4．1．LK4-024LK4-044LK4-055 is the master controller which does not bring to
decelerate
   1．4．2．Eliminates LK4 master controller which 1.4.1 arranges in order,Other LK4 master controller brings the reduction gear
   1．5．LK4-148/3LK4-148/4LK4-168/3LK4-168/4LK4-188/4The master controller has two groups of cams assemblies, after the
reduction gear AND-OPERATION organization joint, decelerates may cause
two groups of cams assemblies parallel rotation or the series
rotation.
   1．6．The LK4-658 master controller is the waterproof type, has group of
cams assemblies, with installs the worm reducer and the drive shaft
joins in the master controller shell. Should the master controller
contact series have slightly is different with other master
controllers, in its 5 electric circuits 2 electric circuits may
install the extinguishing of arc installment, therefore above calmly
touches the headgear by the arc cover, establishes the magnetic field
by the arc-suppression coil to produce magnetism to blow the function
but to achieve the extinguishing of arc function.
