Safe OPN OPENING 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 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.
Auxiliary power connection. Provides a +12V DC supply for auxiliary
Aux 12V
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 and receivers 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 OPE and reverse functions are not required a link
must be fitted between safe OPE and COM for the controller to
operate normally. )
