English Multi-Timer
4. Operation overview
The Multi-Timer has 4 outputs to control downstream circuits. In order
to release the switching operations, the contacts of the 4 related
switching inputs have to be closed. The switching duration can be set
via trim-pots individually for the different switching operations.
There are four different modes of operation available:
when used in analogue or digital layouts:
1. time switch,
2. pulse delay,
3. random switch;
when used in analogue layouts:
4. start-brake-stopover switch.
The mode of operation has to be set by means of jumpers. The
operation modes 1 and 2 are set to the 4 outputs of the Multi-Timer
individually. Thus using one Multi-Timer as a combined time switch and
pulse delay is possible. When using one Multi-Timer as a ramdom
switch or a start-brake-stopover switch, the setting is effective for the
whole module.
The Multi-Timer works like a switch and does not provide current for
the operation of downstream circuits at it´s outputs. Therefore the
downstream circuits have to be provided externally with current. It is
possible to use d.c. as well as a.c. voltage for the power supply.
Operation mode 1 "Time Switch"
The activating time has to be set individually at a trim-pot for each
output. The maximum activating time is 4,5 minutes.
After the closure of the contacts of a switching input the related output
is switched on for the set time. In order to release a switching pulse
push-buttons or comparable external circuits can be used.
