BOLLARD WITH SOLENOID VALVE (OPTIONAL ACCESSORY)
With the version of the bollard where a solenoid valve (24 Vdc) is fitted, in case of power failure, the post is allowed to lower by
itself flat to ground level.
If a solenoid valve is fitted, a voltage stabilizer is also required: this accessory is absolutely necessary and is to be fitted between
the solenoid valve power output (terminals 22 and 23) and the solenoid valve.
Be reminded that only one stabilizer can be fitted to each solenoid valve.

Pressure switch adjustment:
1)
Unscrew the
M5
pin
2)
Adjust the sensitivity using an
allen key size 6:
Clockwise
= increase detection
threshold (kg).
Anti-clockwise
= decrease
detection threshold (kg).
Once regulation is finished tighten

BOLLARD FITTED WITH PRESSURE SWITCH ie. PRESENCE DETECTOR (OPTIONAL ITEM)
In the version where the bollard is fitted with a pressure switch, any obstacle standing on the post prevents it from rising, or should
the post be in the rising phase it reverses movement and lowers completely flat to ground level. The pressure switch is factory preset
for a minimum weight of about 15 kg. A new setting is possible to be made though, in compliance with the installation requirements.
