The memory input
. (A normally-open potential-free input). The
memory input counts and stores each trigger impulse. The boom pole
will stay raised until the same number of closing signals is applied to
the closing input, such as the closing loop. This input is typically used
in conjunction with the Complex (CMX) Mode of Operation
LCK/STP
Holiday lockout or boom stop input
. (A normally-closed potential-
free input). For as long as a connection between this input and Com
is maintained the controller will behave normally, but when the
connection to Com is broken all inputs are inhibited
ILP
The inductive loop detector input
. (A normally-closed potential-
free input). As long as a connection between this input and Com is
maintained the controller will behave normally. When this connection
is broken, i.e. a vehicle drives onto the inductive ground loop, it will
prevent the barrier from lowering if it is stationary, and will stop and
raise the barrier if it is lowering
Aux 12V
Out
Auxiliary power connection
. Pr12V DC supply for auxiliary
equipment such as a radio receiver, photo cells, etc. It is electronically
limited to 300mA
RELAY/
RELAY
Ticket vending interlock
. These two terminals provide a normally-
open potential-free contact which is generally used to introduce an
electronic “lock” to ticket vending devices, meaning that tickets cannot
be dispensed while the boom pole is raised or raising. Alternatively, the
terminals can be used to connect a courtesy or security light which will
illuminate whenever the barrier is operated. Com will cause the boom
pole to raise, stop or lower depending on the operating mode selected.
Each trigger impulse received will cause the barrier to react accordingly
