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.
The circuit is triggered by a positive switching pulse at the module´s
input, for instance via a key switch or a reed contact. Then the output
is grounded for the preset time.
Devices with a current up to 100 mA intended to be switched on can be
connected directly to the minitimer´s output. Devices with a higher
current or devices intended to be switched off, can be controlled via a
relay. It is also possible to switch over between two devices by
connecting a relay.
Minitimer MT-2 "Delayed switching"
The minitimer MT-2 switches on or off operations in model railways
with a time delay between 0 and 25 seconds. The desired time delay is
set via a trimming potentiometer.
Examples of use: Delay of a locomotive´s start after changing the
signal to "go" (= the engine driver´s reaction time).
The circuit is triggered by grounding the module´s input, e.g. via a
switch. The module´s output is grounded after the preset delay time
has elapsed, the connected device consequently is not switched on until
the delay time is over.
If the earth connection at the module´s input is interrupted, the
connected device is switched off with a time delay of approx. 1 second.
If the time passing between making and interrupting the earth
