Maintenance - RIB INDUSTRIAL Handbuch

L
IMIT SWITCH SETTING
Normally the barrier is supplied to you with the limit switches already set
to allow optimum barrier movement.
If the base plate has not been cemented in on a level plane, the boom
might be not perfectly horizontal or vertical, with the result that the
aesthetic appearance of the installation is poor.
To prevent this, the mechanical travel of the boom arm can be modified
by means of the limit switches, using two N° 9 wrenches.
Now adjust the electric limit switches by means of pawls "A" (Pic. 5)
mounted on the disk, using a N° 10 setscrew wrench to slacken the bolts
that lock them on the same.
A
DJUSTMENT OF THE SAFETY CLUTCH
To be undertaken after disconnecting power supply.
N.B.: These operations must be executed only after the power supply
has been suspended.
1 - Unscrew the unit with a 19 mm wrench (4).
2 - Hold the motor with a 15 mm wrench and turn the screw (3)
clockwise (with the given wrench) if you want more force or unscrew
it if you need less.
3 - After regulating the clutch do not forget to clamp the nut (4) at the
shaft's end.
E
MERGENCY RELEASE
The mod. INDUSTRIAL barrier can be manually operated in a blackout
by inserting the crank into the hole on one side (Pic. 7).
When the crank has been inserted, a switch will depress and disconnect
the line. This prevents the operator from being injured by sudden
unexpected manoeuvres if the electricity supply returns.
M
AINTENANCE
To be undertaken by specialized staff after disconnecting power
supply.
After every 50.000 cycles check the tightness of the boom holding
attachment, and the wear on the mechanical stops.
Grease the bearings of the boom carrier shaft.
