3.i) PISTONS WORKING TIME PROGRAMMING:
PROCEDURE:
1) Push and keep pushed the PROG button (the led OK and the led EXT are on, fixed)
2) After about 3 seconds, the led OK starts flashing
3) Release the PROG button, the led OK keeps on flashing
4) open the contact f2(4) for the time you wish to memorize
5) When the contact F2(4) is closed, the led OK turns off and the procedure is finished
3.l) CLOCK PROGRAMMING:
to program the clock, the DIP1 must in on.
note: connect the clock contact without tension in place of the CH input (terminals 5-7).
thanks to this function, the road will be open until the contact of the clock is closed and it will close when the
clock contact is open.
In case of power failure, at the revival of power the central guarantees the reopening or the reclosing even if the
clock has commuted while the central was off.
When the clock contact is closed, the pause management is excluded. If during the automatic reclosing of the
clock, the security f2(4) intervenes, the bollard reopens and it will try to reclose after 5minutes the closing
attempts will continue until the bollard isn’t closed or coming a user’s command.
3.m) ACTIVATION OF HYDRAULIC PRESSURE RETENTION:
to activate this function, DIP 2 must be in “on”.
When the system is in CLoSe state, the control board check the position of closing limit switches.
If the limit switches have inverted their state, due to pistons lowering, the control board commands the closing of
the bollard. the control is done every 10 minutes and the forced closing lasts up to the reaching of the limit switches
or to a maximum of 3 seconds. Before the forced closing the bollard makes some signalling flashes. The flashing
light doesn’t work during the forced closing. During the forced closing the safeties f2(4) don’t order the inversion but
only the stop.
3.n) EXCLUSION OF THE DELAY TIME OF THE LIMIT SWITCHES:
Usually, the engines stop after 250ms from the opening of the contact of the limit switches. thanks to this
procedure it is possible to exclude the delay letting stop the engines as soon as the limit switch contact is open.
It turns on placing the DIP4 in on.
