  • Page 9: Operation Overview

    English 4. Operation overview Minitimer MT-1 "Time Switch" The minitimer MT-1 is designed for controlling operations in model railways which are supposed to last for 1 to 100 seconds. The desired switching time is set via a trimming potentiometer. Examples of use: Automatic opening of the gate at a level crossing after a certain time, automatic stop of trains at the platform for a certain time.

  • Page 14 English MT-1 | MT-2 | MT-3 Trimm-potentiometers Trimm-potentiometers (abrv. "trimm-pots") are resistors which allow the value of resistance to be varied and that way to be adapted to the particular demands. In the middle they have a small slot into which a small screwdriver can be put in order to vary the value of resistance.
  • Page 15 MT-1 | MT-2 | MT-3 English Diodes and Zener diodes Diodes allow the current to pass through in one direction only (forward direction), simultaneously the voltage is reduced by 0,3 to 0,8 V. Exceeding of the limit voltage always will destroy the diode, and allow current to flow in the reverse direction.
