English KSM-3
Connecting points
Connecting points to the KSM-3 is optional. You can do without when
you do not intend to switch the points automatically.
Each of the two isolating points is assigned firmly to one position of
points. If the position is "branch" or "straight" depends on the particular
mounting situation.
For that reason you have to check after having connected them if the
points switch "correctly", when the locomotive passes the isolating
points on its way out of the loop. If not, you have to interchange the
connections of the points (X3-1 and X3-3).
Setting the sensitivity for the polarity reversal
Proceed accurately when setting the sensitivity for the polarity reversal
in order to make sure the KSM-3 already reacts at the beginning of the
voltage drop and alters the polarity within the loop as quickly as
possible. If the inevitably occuring short circuit lasts too long, wheels,
rails and current collectors possibly corrode or locomotives passing the
sectioning point possibly jerk. With a very high current the short circuit
interruption of the booster possibly reacts.
First set the trimm-pot by use of a small screwdriver as far to the left as
possible. Then turn it
1. slowly to the right, until the LED lights up or flashes
2. further to the right, until the LED goes out or the relay
switches (audible by a clicking sound)
3. carefully back to the left, until the LED lights up or flashes
again or the relay stops to switch
