The bollard rises
of about 10 cm,
stops and then
returns in low
position (without
any lowering
control). (C001)
The bollard rises
but not
completely.
(C002)
Once the bollard
is in down
position, the
cylinder is about 7
mm lower than the
frame cover.
(C003)
The safety pressure switch which
detects the presence of about 40
Kg weight on the bollard head is
constantly in ON position and for
this reason it must be adjusted or
replaced.
• There is too little oil in the
hydraulic pump tank.
• Bollard's connecting cables are
not well placed in the foundation
box. If the upper limit switch gets
stuck in the cable, the function of
the bollard may be impared.
The vulcanized hard rubber of the
lower base supports is worn.
PROBLEM
POSSIBLE CAUSE
SOLUTION
When the bollard is in low position check the leds L1 on
the master and/or the slave unit in the control unit:
switched off = the pressure switch is ok – turned on = the
pressure switch is in alarm (it is on) – if the led is always
turned On or turns On when the bollard starts rising, the
problem is caused by the dafety pressure switch which
must be adjusted or replaced.
For the pressure switch adjustment please consult
chapter 10: SPECIFIC OPERATIONS.
Note: generally only the pressure switches of old supply
are adjustable and recognizable from a waterproof
protection made by black soft rubber; the current
pressure switches are pre-adjusted and hermetic to
increase the IP grade of protection.
• Check whether oil is leaking from the hydraulic
assembly, hydraulic lines or connections. Check
whether all hydraulic connections are properly
tightened using a corresponding open ended spanner.
Refill oil into the hydraulic assembly once the oil leak
has been remedied. Read chapter 10: SPECIFIC
OPERATIONS.
• Pull the bollard out from the foundation box and check
if the bollard can fully rise. If the test is positive, put the
bollard back into the foundation box and make sure that
the connecting cables are positioned correctly.
Replace the lower support bases.

This guide shows the most common problems that can occur while using a GI.BI.DI.
Client's technicians can solve some problems indipendently (especially if they are equipped with spare parts), while
for other troubles it may be necessary to be supported by GI.BI.DI. S.r.l assistance department.
In this case they have to contact GI.BI.DI. S.r.l., communicate the reference number of the system (or the reference
number of the order confirmation).
