Mode of Operation
The I/O-units use three
wires
for the communication
with all the other I/O-units of
an installation, for the sup-
ply of the I/O-units and for
the loads connected to the
outputs of the units. This
implies, that the “common”
of the communication signal
is identical to the “minus” of
the supply.
The DC-supply voltage must
connect
to
through a G 2196 0000 700,
which also performs the chan-
the
system
nel generator function and the
RS485 communication link to
the elevator controller (please
refer to the data sheet for G
21960 000 700 for details)
Each I/O-unit has 2 inputs
(NPN/contact) and 2 PNP-
outputs. Every input and
output is given its individual
address with the coding unit
GAP 1605 (please refer to
the respective data sheet for
details). The ON/OFF-signal
that is applied to the input
of an I/O-unit is associated
to the address given to that
input. Any output of an I/O-
unit that is given the identi-
cal address will now follow
that input signal and switch
its output signal ON or OFF.
This means that a signal
which is input at one loca-
tion (for example as an out-
put from the lift controller)
may be output wherever
required and as many times
as required.
An input pulse stretcher is
used on every input to
assure that the changes of
input signals (even extreme-
ly short ones) are communi-
cated by the system.
The output status of all out-
puts of an I/O-unit may be
pre-defined for cases like
loss of power and loss of
communication. Please refer
to the paragraph “Output
status setting” of the data
sheet for the GAP 1605 to
change the default setting
(all outputs OFF).
