Description and examples of operation modes with the internal relays, connections
8.5.1. CASE 1: drive two electric locks with system powered with external power supply
In this example AA-514 activates the two separate electric locks with a voltage pulse common to its own supply
voltage. In the example the relay1 acts on the electric lock of driveway gate, while the relay2 acts the electric lock
of the pedestrian gate. Please note that is needed to connect the terminal blocks TB1, TB3, TB4 as shown, the
power supply is unique and common. The telephone line must be connected on the TB2 terminal block. The
connections to be made during the stages of installation are shown in dashed lines.
In this example, the correct values of the parameters involved in the management of the relays could be:
•
parameter 138 = 0
the relay1 is activated by telephone code
•
parameter 144 = 0
the relay2 is activated by telephone code
•
parameter 137 = 2
pulse time opening driveway gate, relay1, in seconds
•
parameter 142 = 2
pulse time opening pedestrian gate, relay2, in seconds
