KSM-3

5. Checklist for troubleshooting and error correction

Warning: If you notice a strong heat development, immediately disconnect the
!
connection to the supply voltage. Fire hazard!
Possible causes:

One or more connections are faulty. à Check the connections.

"Kit" version: one or more components are soldered incorrectly. à Carry out a visual
inspection (à section 3.6.) and eliminate the faults, if necessary.

The current consumption of the vehicles in the terminal loop exceeds 8 A. à Reduce the
current consumption.

The module is defective. à Send the feedback module in for inspection.
When setting the trimming pot the rlay does not switch.
Possible causes:

"Kit" version: One or more components are soldered incorrectly.  Perform a visual check.

"Kit" version: The IC has been inserted into the IC-socket in the wrong direction.  The IC
has consequently been destroyed and must be replaced. (The programmed IC can only be
purchased directly from Tams Elektronik!)
During operation the central unit switches off.
Possible causes:

"Kit" version: One or more components are soldered incorrectly.  Perform a visual check.

The trimming pot is set incorrectly.  Set the trimming pot according to the section
"Setting the operating point" and repeat the test.
When the train is driving out of the loop the points are switched incorrectly.
Possible causes:

The connections X3-1 and X3-3 have been assigned incorrectly.  Interchange the
connections.
When switching the points, a short circuit occurs, possibly the points clatter.
Possible causes:

The current needed to switch the points is higher than 1 A.  Solder a choke (e.g. 3,3 µH)
into the conductor to the points´voltage supply (middle connector).
