The 230/400VAC electric line which powers the control unit must be protected by
a differential magnetothermal switch. In particular, it is necessary to check that it
stops the power supply in case of earth fault (electric leakage) or electric shock,
providing either direct or indirect protection to persons (lifesaving). By means of
the suitable instrument (loop tester) check the proper operation with regard to the
isolation and the continuity. In addition push the TEST button of the switch and
verify that it springs in OFF position to confirm the proper functionality.
Check the correct function if the bollard system is equipped with induction loops
and a loop detector installed in the control. For this, place a test metal mass (e.g.
a metal box with metal tools inside) on different sections of the induction loops
and check whether the LED on the loop detector is illuminated in red (when
induction loops are free, the LED is blue). Perform the same test during
extension of the bollard. The bollard must stop and return to the lowered position
if it is functioning correctly. Check and correct the cause in case of incorrect
function.
If the bollard system is equipped with automatic lowering device, rise the bollard
to up position then turn the power in the control unit off and check that it lowers
automatically.
If the system is not equipped with automatic lowering device, check that the
manual lowering device works properly. Read chapter 10: SPECIFIC
OPERATIONS.
If the system is equipped with radio receiver and transmitters, check the correct
operation from a distance of about 30m and, as far as possible, verify the wear of
the transmitters and the built-in batteries.
Check visually the overall status of the control unit and in particular verify that
there are no slack wires in the terminals, sparking relay contacts, oxidised
terminals or similar. Check the general conditions of the case and the door
gasket which must ensure the IP protection class.
If the bollard is equipped with the multiled flashing light, check the overall
conditions and the operation of the 25 led points. In case of partial or total failure,
restore the operation of the flashing light. Read chapter 10: SPECIFIC
OPERATIONS.
If the bollard is equipped with traffic lights, check their overall conditions. In case
of fault of one or more light sectors, replace the filament bulb (traffic light - old
version) or the LED (traffic lights - current version).
Check the proper operation of
the differential magnetothermal
switch of the electrical circuit.
