During the rising
phase, the bollard
does not perform
the reversal
managed by the
pressure switch.
ATTENTION: when
bollards are
equipped with
E.F.O the reversal
function is not
operative. (C004)
The bollard rises
completely but the
hydraulic unit
continues working
for about 10”.
(C005)
The bollard
completes the
rising phase, but it
performs the
reversal and turns
back in lower
position. (C006)
• The dip switch 5 of the master
unit is in ON position (stop
function by pressure switch is
excluded).
• The pressure switch does not
detect any pressure increase in
the hydraulic circuit.
• The hydraulic unit does not
generate the correct operating
pressure.
• The dip switch 4 of the master
unit is in ON position (the stop
function by pressure switch is
excluded).
• The pressure switch does not
detect any pressure increase in
the hydraulic circuit.
• The hydraulic unit does not
generate the correct operating
pressure.
The adjustable parameter in the
master board which corresponds
to the reversal time in case of
alarm of to pressure switch pre-
adjusted, must be lowered of 1”.
• Only for cold territories: there is
no heating device or it does not
work.
• The piston rod is “dry” and must
be lubricated.
• The bollard was bumped
violently when in high position so
the piston rod is crooked.
• Set the dip switch 5 of the master board in OFF position
(reversal function by pressure switch enabled).
• If it is possible adjust the pressure switch sensibility
(adjustable old version) or replace the pressure switch
(pre-adjusted and hermetic new version to increase the
IP grade of protection and the system reliabilty). For the
pressure switch adjustment please consult the chapter
10: SPECIFIC OPERATIONS.
• Adjust the maximum rising pressure in the hydraulic
unit. For the adjustment, please consult the chapter10 :
SPECIFIC OPERATIONS.
• Set the dip switch 4 of the master board in OFF position
(the stop function by pressure switch is enabled).
• If it is possible adjust the pressure switch sensibility
(adjustable old version) or replace the pressure switch
(pre-adjusted and hermetic new version to increase the
IP grade of protection and the system reliabilty). For the
pressure switch adjustment please consult the chapter
10: SPECIFIC OPERATIONS.
• Adjust the maximum rising pressure in the hydraulic
unit. For the adjustment, please consult the chapter10 :
SPECIFIC OPERATIONS.
Request to Gi.Bi.Di. S.r.l. the specific document for the
programming software, communicating the code on the
master board; perform the parameter 1 adjustment
lowering the time of about 1”.
• If there is no heating device, install one in each bollard;
in presence of heating device, check the proper
operation of the resistance and the thermostat.
• Lubricate the piston rod.
• Replace the piston.
UK
The bollard is in
high position and
a lowering com-
mand is given, but
the bollard
remains up and
lowers only after
an initial pressure
downward. (C007)
