CONNECTION TO A SIEMENS T400
To simplify connecting the MOVA unit to a Siemens Type 400 traffic controller, an
alternative cableform is available.
This cableform connects the first BUS / MOVA (Digital) I/O Board’s connectors PL1 and
PL2 directly to the controller’s UTC Expansion I/O Board’s four connectors PLB, PLC,
PLD and PLE. This cable also commons the 24V and 0V connections and thus only
requires two wires to be connected to the controller’s 24V and 0V supplies.
It cannot however replace the detector cables and these still have to be connected
during installation. Note that the colours of these wires are the same as the colours
used in the standard cableform that is detailed on the previous page.
