Instructions for Faac induction loops.
You need to think carefully about how they should work, i.e. whether the loop should be from the street or from the courtyard (or both), at what distance from the gate you want to install it and in general how it should work.
To describe the simpler loop (single channel) - it has two relay outputs. One reflects the state of the loop - without the car the relay is open, with the presence of the car in the loop the relay shorts (or vice versa, depending on the setting of the micro switch). The second output, pulse output, is short-circuited for 0.2 s when a car leaves the loop.
The pulse output can be used by connecting it to the control unit's OPEN A input, but it must be far from the gate, i.e. more likely only from the courtyard, and when the gate is open and entering from the street, passing through the loop will cause it to close. It is also possible to set the control unit for two-channel operation, i.e. the loop will only cause the gate to open and closing from the remote control with the second button, or to set the gate control unit for estate operation, i.e. the impulse from OPEN A will only open the gate, and closing will be automatic after a time delay.
