2.7 EFO (EMERGENCY FAST OPERATION -
OPTIONAL)
The bollard J355HA M50 can be equipped with an EFO (Emergency
Fast Operation) emergency activation system, which can be activated
at any time to raise the cylinder immediately. The EFO system consists
of a tank, a pressure switch and a solenoid control valve powered by
230V ~
In order to connect the solenoid valve (this varies depending on the
N.O. / N.C. option adopted), refer to
13
, terminals 4 and 5.
The N.O. solenoid valve (“Blackout” model) enables the EFO to be
activated, both on the command of the operator and in the event of
a power failure, while the N.C. version only allows for the voluntary
activation of the device.
