MERGENCY RELEASE
Carry out only after power supply to the motor has been interrupted!
In the event of a power supply failure, release the gearmotor, so that you
can move the boom by hand.
To do so, use the RIB key supplied and turn it in the clockwise sense,
until the stop is reached (Pic. 6).
By doing so, the barrier boom works independent from the gearmotor and
it can be moved by hand.
When power is supplied again, turn the key counterclockwise strongly
until you block it.
M
AINTENANCE
To be undertaken only by specialized staff after disconnecting
power supply.
After every 100.000 cycles check:
- boom balance (see the paragraph “ADJUSTING THE BALANCING
SPRINGS”);
- the tightness of the release knob (see the paragraph “EMERGENCY
RELEASE”);
- the tightness of the boom holding attachment and the implantation of
the boom (see the paragraph “ASSEMBLING THE BOOM”);
- the wear on the mechanical stops and the limiti switch setting (see the
paragraph “LIMIT SWITCH SETTING”).
- Grease the bearings of the boom carrier shaft and the threaded spring
guide bar.
The described maintenance is vital for the corrected operation of
the product in the time.
