figure 3- 821HSX fully featured handset configuration
The configuration shown in
figure 3
encompasses the many differentiations to the handset
controls. Feel free to experiment by adding or deleting functions. Experiment with the values of
the components and observe their effect on the operation of the throttle. When you have decided
on the final configuration, choose a suitable enclosure and plan the control and switch placement
for comfortable operation. One-handed control is very desirable and your handset should be
maximized with this goal in mind.
ADJUSTMENTS
The trimpot labeled “VOLTS” is located within the heat sink area. This should be adjusted to your
desired full speed voltage. This can be done by running a locomotive up to the full speed setting
of the throttle and adjusting until the optimal full speed is established. The “FREQ” adjustment is
factory set at 60Hz and shouldn’t need to be adjusted unless you have a “stubborn” locomotive
that may be more responsive at a different setting. Run the locomotive at very low speed and
then adjust for maximum controllability in conjunction with the speed control at low speeds.
