Safe OPENING edge safety input. (A normally-closed potential-free input).
OPN As long as a connection between this input and COM is maintained the
controller will behave normally. When this connection is broken it will
prevent the gate from opening if it is stationary, and will stop and reverse
the gate if it is opening. This input has no effect if the gate is closing.
Safe CLS CLOSING edge safety 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 it will prevent the gate from
closing if it is stationary, and will stop and reverse the gate if it is closing. This
input has no effect if the gate is opening.
LED External gate status indicator. (A low-current output signal.)
An output terminal which provides a low-drive (approx. 4,5V DC, 20mA)
to an 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.
Aux 12V
Auxiliary power connection. Provides a +12V DC supply for auxiliary
equipment such as a radio receiver, Safety Beam(s) etc. It is linked directly
to the battery positive via a 3A resettable fuse.
Safe Used for switching the power supply to the Safety Beam(s). If automatic
Common beam testing is required, the negative power supply connection of the
beam transmitters must be wired to this point.
When setting up the controller for the first time or after a full reset back to factory
default has been performed, the system will electronically override the Safety Inputs
and allow the system to function without the links. However, if safeties are connected to
either or both inputs thereafter, there must be a normally-closed circuit maintained for
the system to operate correctly. I.e. if beams are fitted and then removed, the circuit
which is affected must be replaced with a wire link to create the normally-closed circuit.

If the Safe OPN function is not required a link must be fitted between safe
OPE and COM for the controller to operate normally.
