2) Product description and applications

The electronic card is suitable for controlling road boom gates models "WIL 4" and "WIL 6" with 24 V d.c. motors.
The actuator has a limit switch with a speed control system that makes it possible to reach the travel limits by means of a slowing down
phase. In addition, the effort the motor is subject to during movement is promptly detected as well as any obstacles that may be in the path
and in such an even direction is reversed.
It can be controlled "manually", "semiautomatically" or "automatically". There are also certain functions like "Reclose immediately after Pho-
tocell" or "Reclose always", "Flashing also in pause" as well as other operating functions such as "Gradual Start-up" and "Slowing down" (a
standard feature) plus a sensitive "Brake" that only comes into play if movement has to be stopped hastily.

The task of the OK LED (7) is to signal the correct functioning of the internal logic; it must flash at 1 second intervals and indicates that the
internal microprocessor is working and waiting for commands. Whenever there is a variation in the state of the inputs or of the function dip-
switches (1), a double, quick flashing is generated even if the effects of the variation are not immediate.
When the unit is powered, the luminous indicators (16) on the inputs turn on if that particular input is active and if there is a control voltage
of 24 Vcc. As a rule, the LEDs on the safety device inputs STOP, PHOTOCELL and PHOTOCELL 2 and those on the limit switches are always
on while those on the STEP-BY-STEP, OPEN and CLOSE are normally off.
During movement, the current absorbed by the motor is measured; when it exceeds a certain limit (adjustable with the trimmer) the safety
system is activated which causes movement to stop with the aid of the brake (removing the residual part of accumulated kinetic energy);
then, if one of the automatic functioning modes is active, a movement in the opposite direction starts. To increase the level of safety still fur-
ther, if the STOP_AMPERE system comes into play three consecutive times without ever reaching any of the natural ends of the movement,
a final STOP is carried out.
