Pantograph Installation
The pantographs are packed the in the compartments in the top of the styrafoam
box lid. One pantograph is stored in each of the compartments in the lid. Carefully
remove the pantographs from the compartments and install them on the top of
the body shell. Please note that each pantograph has two small arms extending
from the bottom. These arms are used to raise and lower the pantographs. To
insure proper operation the arms must position between the 2 sliding blocks that
can be seen in the slots on the top of the body shell.
To install the pantographs, place the engine on the track and apply power. If you
are using the MTH DCS system you will need to initiate the start up function.
After the pantograph motors go through the initialization the sliding blocks for the
rear pantographs should be apart. If they are not completely separated, move the
blocks away from each other using a small jeweler's screwdriver, then install the
pantograph as described below.
Installation
To install the rear pantograph, gently collapse one of the pantographs and place it
in the location for the rear pantograph. Be sure that the small arms on the bottom
of the pantograph fit in between the slots between the sliding blocks, then align the
center pin and the four insulators, before applying downward pressure to seat the
pantograph in place. The rear pantograph should now be at maximum height. If
not the hold down latch may be engaged. To disengage the hold down latch, hold
on to the base of the pantograph and gently pull up on the contact slider.
To install the front pantograph reverse the direction of the engine (using the
control transformer, power pack or the DCS Remote) so that the rear pantograph
collapses. Then make sure the sliding blocks for the front pantograph are spread
apart and install the front pantograph using the same procedure as the rear
pantograph.
If the pantographs are installed properly, at each direction change the down
pantograph will raise and then the raised pantograph will lower. This insures that at
least one pantograph is in contact with the overhead catenary. This is important if
you are operating using catenary power. If both pantog raphs loose contact with the
catenary the engine will loose power.
