Installation
Of The Switchmachine MAW02-S
Preparation
of the Layout Board
First,
mark the centre position of the turnouts tie bar.
At this location, drill a 12mm hole or a corresponding long slot.
Using the template provided, mark the mounting holes from underneath the
layout. Hole for flexible rod, left
or right, depending on space conditions. Instead of long slots, round holes of
12mm (1/2") may also be used.

Preparation of the Switch Machine
As
delivered, there are two flexible throw rods attached to the cover of the
mechanism. These should be removed
first.
3.
Attaching the Throw Rod
Depending
on the existing conditions (thickness of the layout plate, desired throw
pressure; etc.) select the thicker-or thinner rod and attach it to the
traversing rack, using the screws provided. For JHM-switches the use of the thinner throw rod (0.5 mm) is
recommended.
4.
Final Mounting
The
assembled switch machine may now be fastened under the layout plate.
The adjustment lever may be used to achieve small adjustments. In
addition, by using the red lever on top of the housing, it is easy to establish
the center position of the rack. Since
the traversing rack may be moved by hand, pressing the red lever on the housing
makes it possible to locate the center position of the rack.
This makes an exact adjustment of the flexible rod possible. It is important that there is no obstruction to prevent the
traversing rack from traveling to its full extent in both directions, in order
to activate the automatic shut-off and permit reverse operation.

Wiring
Operating
Voltage: Brown to Turnout Controls, Red to Power Pack (16 Volts AC, 1 Ampere).
Polarization of the Turnout: Yellow to the Turnout Frog, Blue to the
Turnout Points. Since the switch
machine includes an automatic shut-off device, it is possible to use either push
buttons or toggle switches to operate the machine.
If you mount your
points with a tiebar under the baseboard you will need an alternative way of
connecting the point machine. A way
I have found that works is to bend a 90-degree angle in the wire and connect as
shown below.
Accessory/Conversion
kit for Hoffmann point motor
Contents:
1 Conversion kit for Signals, 8 hole covers
The
conversion kit changes the direction of movement of the MWA 02-s point motor to
become vertical for use with signals etc.
All
necessary parts including a preformed wire for the throw rod are present.
The
slotted covers fit in the hole between the point motor and the tie bar. There
are eight covers with different size slots in them.
1.
Signal operation
Separate the necessary parts from the sprue.
Remove
one retaining screw from the point motor housing and the screw retaining the
point actuation lever.
Position
the cam between the actuation lever and the traversing rack and fasten with
screw.
Place
the throw rod (preformed wire) in the correct slot on the mounting plate.
Fasten
down with screw and position the wire over the cam.
Connect
the signal push rod to the throw rod and adjust for correct operation.
2.
Hole covers
Drill
a hole (10 or 12 mm) in the layout board using the template.
Push
the correct cover into place and make sure it is flush with the top of the
layout board.
Attention:
Make sure the slot is in line with the movement of the throw rod.
Place
the turnout.
Place
the point motor.
3.
Alternatives
If
you combine two covers with the slots at a 90 degree angle of each other you
create an extra joint for the movement (useful for thick layout boards to
preserve the right amount of movement and/or the correct pressure).
Auxiliary
switch for point machine
Assembly
instructions
On
the accessory free side or the point motor remove the retaining screw.
The
mounting plate for the switch is placed on the switch in such way that the lever
faces towards the traversing rack.
Install
the switch on the point machine.
Important:
The
lever must be placed in the hole on the traversing rack.
Install
point machine as per instructions.
The
switch is rated for 24 V and 4 A.
