Oil leaks See point 1 See point 1
Manual unlock is open See point 3 (O-Ring unlock damaged) See point 3
electric valves are open Cylinder seal Replace cylinder seal
Faulty valve seals Break of the seal valve Replace the O-Ring in the distributor
6
CLIMB GETS SLOWER
(very viscous oil)
Low temperature See point 3 See point 3
Exhausted Oil Replace the oil
Install a resistance
Very high pressure of the bollard
ascent
Too tense pressure valves Relax the maximum pressure valves
Incorrect supply voltage
See point 3 See point 3
Insuffi cient condenser
7 NOISY PUMP Presence of air in the circuit (the
bollard doesn’t go up)
See point 1 See point 1
Too viscous oil Worn oil Replace the oil
(irregular bollard ascent) See point 2 See point 2
Wear pump Excessive inner backlash Replace oil
Dirty oil Replace the pump
8 SEAL OIL LEAKS abrasive substances in the oil Crack on the seal Replace the oil and the seal
Worn seals
High oil temperature Collapsed seal
Refrigerate the oil and replace the
seals

EXCESSIVE CONTROL UNIT SUPER
HEATING
(oil too hot)
Intensive use of the control unit Wear pump Replace the pump
More movements than expected Respect the opera ng cycles
Worn oil Replace the oil
Manual unlock is open See point 1 See point 1
electric valves are open See point 1
Irregular set of the limit switch sensors Wrong reading of the limit switch
Set the limit switch in the right
posi on (check the limit switch
sensor and magnet func oning)
Too high pressure Very ght maximum pressure valves
Set the right pressure by consul ng
“Adjustment of the bollard rising
force”
Oil leaks with loss of pressure See point 1 See point 1
High external temperature See point 3 See point 3
Wrongly regulated valves Oil overhea ng Respect the func on temperature
Low regulated valves Ask the constructor
10
THE BOLLARD DOESN’T
COMPLETELY GO UP
(incorrect regula ons)
Low oil level in the tank See point 1 See point 1
Irregular set of the limit switch sensors See point 10 See point 10
Insuffi cient condenser See point 3 See point 3
Too high pressure See point 10 See point 10
incorrect ming Adjust me on the brain
11 HIGH WATER LEVEL OF THE
FORMWORK
Obstructed sewer
Foliage / debris slow down the waste
water
Do maintenance (clean the well)
non-draining soil The soil absorbs li le water
Build a well or a sewer with pump to
draw waste water
Request an IP67 hydraulic control
unit
12 LIGHTING HEAD NOT WORKING Faulty or wrong regulated limit
switches
Wrong cable installa on
Rewiring respec ng the polarity of
the cables
Wrong connec ons Faulty cables Cables replacement
Socket not connected
Connect the plug into the head
socket
