Check of the GSM activator for
remote control (optional item).
(A020)
If the bollard system is equipped with GSM activator for remote control, check the
correct operation performing some rising/lowering movements from a telephone
and/or a mobile phone enabled for the operation of the system.

Topping up of the hydraulic
unit. (B001)
Check/replacement of the
lowering solenoid valve.

Operation
Procedure
• Lift the bollard out of pit, lower it to down position then turn the power off
230/400VAC.
• Check that the oil level is at least half of the sight glass; if necessary, top up.
• Unfasten and remove the cap of the hydraulic pump (placed on the top of the
hydraulic unit) and fill it with the same oil up to half of the sight glass.
• ATTENTION: USE ONLY ORIGINAL OIL.
• ATTENTION: CHECK IF IT IS MINERAL OIL OR BIODEGRADABLE OIL.
• Turn the 230/400VAC power supply on and rise the bollard to up position.
Check that the oil level lowers at the beginning of the rising phase.
• Once the bollard is up and the hydraulic unit is still (end of the rising cycle),
close the cap of the hydraulic pump.
Lift the bollard out of pit, lower it to down position then turn the power off.
• Unfasten the black cap of the hydraulic pump of about 2 turns (to reset the
internal pressure of the pump).
• Remove the coil from the solenoid valve.
• Unfasten and remove the solenoid valve by means of a fixed wrench size 24
(some oil leaks may occur, use cloth to wipe it clean).
• Verify that the lower part of the solenoid valve is not mechanically obstructed by
impurities such as metal swarf or similar (in presence of impurities, it is
suggested to clean, reassemble the solenoid valve and run functional tests;
otherwise use a new solenoid valve).
• Fasten the solenoid valve and the coil.
• In case of negative logic solenoid valve, on the top there is a push button for
emergency manual lowering, it is recommended to lubricate it and check the
proper operation.
• Turn the 230V power supply on and perform the necessary functional tests.
• When the bollard is in down position check the oil level and, if necessary, top it
up with the same oil type.
• When the bollard is in up position and the hydraulic pump is still (end of the
rising cycle) close the black cap of the hydraulic pump.
