23. Description of terminal functions

12V + Positive battery connection.
12V - Negative battery connection.
Motor Motor output – connects to the thick blue motor wire
Motor Motor output – connects to the thick black motor wire
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
IRB 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 autoactivated via a ChronoGuard auto function 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
autoactivated output, the Aux IO terminal will behave as a Com
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 gate status indicator. (A low current output signal.) An output
terminal which provides a low current, drive (approx. 4,5V DC, 20mA) to a
LED which can be used to indicate the gate status remotely. If more than
three LEDs are required it is necessary to fit the CP78 multi-LED driver
card. For more details on the feedback about the status of the gate
provided by the status LED refer to Section 24.
Aux Activates the pillar light relay. (A normally-open potential-free input).
Momentarily connecting this input to Com will cause the light relay to
energize for a period of time as set in the courtesy light timer menu. If the
connection is made for a period exceeding three seconds the pillar light
relay will latch and remain latched indefinitely until a new momentary
connection to Com is given.
FRX Free-exit input. (A normally-open potential-free input). Momentarily
connecting this input to Com will cause a gate which is closed, or closing,
to open or re-open. If the gate is open, or opening, the signal has no
effect other than to reset the Autoclose timer (if selected). Free-exit (FRX)
never initiates a closing cycle. The only way to close a gate, if only the
FRX input is used, is to activate the Autoclose feature on the controller.
Com The common termination point. All trigger signals, etc. have their return
path to one of the Com terminals.
Battery terminal normally indicated as + or red (right hand
battery)
Battery terminal normally indicated as - or black (left hand
battery)
