Mode of Operation
8-, 16- or 32-channel status
indicator with LED dot dis-
play.
The displays are used to
monitor 1, 2 or 4 Dupline®
channel groups.
The output dots turn on when
the respective channels of
the selected channel groups
are activated by transmitters.
Each dot represents the sta-
tus of one Dupline® chan-
nel. The lowest figure on the
front plate indicates the low-
est channel of the first chan-
nel group and the highest
figure indicates the highest
channel of the last channel
group selected by the code
module.
In case of Dupline® carrier
loss the fault LED and the
output (pins 2 & 5) turn on.
Reaction time typically 1 s.
Note:
• Upon
loss
of
Dupline®
carrier the channel dots of
an LED display turn off.
• If DC-supplied displays are
used the length of the sup-
ply bus must not exceed
3 m in order to avoid distur-
bances unbalancing the
Dupline®.
