10.8. Appendix 8. Terminal descriptions
12V +
Positive battery connection.
Tip: Battery terminal normally indicated as + or red terminal
12V -
Negative battery connection.
Tip: Battery terminal normally indicated as - or black terminal

Aux IO
The
Aux IO
terminal provides an open collector output which can be
used for alarm or auto-function purposes. If the collision alarm output
or the Presence Alarm output has been configured to
Aux IO
, then
the negative of the alarm device must be connected to this terminal.
The positive of the alarm device must be connected to the Aux 12V
Out terminal. Similarly, if
Aux IO
is auto-activated via a ChronoGuard
auto-activation Time-period, the device being switched (typically a 12V
relay) must be powered from the Aux 12V Out terminal, and have its
negative switched by
Aux IO
. If the
Aux IO
has not been selected
as either an alarm-indicator output or auto-activated output, the
Aux
IO
terminal will behave as a ‘Com’ (i.e. battery negative) termination
point. All trigger signals, etc., have their return path to one of the Com
terminals
Com
The common termination point
. All trigger signals, etc., have their
return path to one of the Com terminals
Status
External boom status indication
. (A low-current output signal).
An output terminal which provides a low-current drive (approximately
4,5V DC, 20mA) to a LED which can be used to indicate the boom
status remotely. If more than three LEDs are required, it is necessary
to fit the CP78 multi-LED driver card
Aux
The lowering input
. (A normally-open potential-free input).
Momentarily connecting this input to Com will cause the boom-pole
to immediately lower regardless of which position it is in, unless it is
already fully lowered
FRX
The raising input
. (A normally-open potential-free input).
Momentarily connecting this input to Com will cause the boom pole
to immediately raise regardless of which position it is in, unless it is
already fully raised
Com
A second common termination point
. All trigger signals, etc.; have
their return path to one of the Com terminals
NMI
The non-memory input
. (A normally-open potential-free input).
Momentarily connecting (e.g. using a normally-open pushbutton or
the Common and NO (normally-open) of a relay contact) the NMI to
Com will cause the boom pole to raise, stop or lower depending on the
operating mode selected
