Accessory Decoder LS 100/110
pulse duration a new switching command is received by the
LS100/110, the output remains active for another pulse
duration.
Constant output:
By pressing the ‘+’ key on the LH100, the function device
is activated and remains active until the ‘-’ key is
pressed at which time the - output is activated. Thus either the
+ or - terminal of an output is active, the output operates as a
toggle switch:
For example, if you were to connect a red lightbulb of a signal
to an output’s + terminal, and the green lightbulb to the -
terminal, then when you press the ‘+’ key, the red lightbulb will
be on (the signal shows ‘stop’). If you press the ‘-’ key, then the
green lightbulb is on (the signal shows ‘go’). This avoids the
need to use an additional relay on light signals.
Flashing:
In this mode an output’s + and - terminals are activated
alternatingly.
This mode of operation is suited for connecting the flashing
lights at a train crossing or signal. The flashing rate is
programmable; see the section “Programming the settings of
an output” for more information.
General notes: Only one of the output pairs on an LS100/110 is
active at any one time. For example if during pulse or constant
operation the + terminal is active and the - output is activated,
then the + terminal goes inactive, regardless of whether the
pulse duration time is up or not. This applies in the
corresponding manner when the - terminal is activated first and
the + terminal is then activated.
Caution!
When programming the outputs, please note that depending on
pulse duration, or with constant operation, several outputs may
be active at the same time. With all the connected power users,
you must then not exceed the maximum total current load
capacity of 3A for the accessory decoder.
