2.1 Intended use
The speed governor is produced in compliance with the state of the art for safe
and reliable use. It is forbidden to tamper with devices or functions designed to
prevent accidental contact.
It is prohibited to use the safety limiter for activities other than the one for
which it was produced and the conditions set out in the supply contract.
!

5. DESCRIPTION AND OPERATION
5.1 General description
The speed governor is a safety device that trips when the car reaches the inter-
vention speed at which it is calibrated.
Governor:
• One-way - it operates the safety gear lever in its downwards movement.
• Two-way - it operates in both travel direction.
Thespeed governoris designedfor detectingthe excessspeed andto intervene
both mechanically and electrically as below described:
• the mechanical part activates the safety gear
• the electric part stops the lift drive
Note: A tension device is required to tension the speed governor rope
(see for example TAB163.1 and TEV on product general catalogue of
Montanari Giulio & C.)
5.2 Components
The following figures show the parts forming the NOR - RG - RH governor in
standard version.

5.3 Mechanical intervention
Fig. 6 - 7 - 8: The wheel (1) rotates on the pulley square (2) and pulls the lever (3)
downwards.
In this way, the spring (4) prevents the lever from opening until the intervention
speed is reached.
The lever (3) rotates and engages one of the locking teeth (5).
The pulley does not rotate anymore and causes the mechanical intervention of
the safety gear.
5.4 Electrical intervention
Fig. 6 - 7 - 8: The wheel (1) rotates on the pulley square (2) and pulls the lever (3)
downwards. In this way, the spring (4) prevents the lever from opening until the
intervention speed is reached.
The pin rises, activates the safety contact (7) and opens the safety chain.
6. INSTALLATION AND FIXING
The speed governor must be installed in a building or in a closed travel com-
partment.
Do not use in an explosive atmosphere. Room temperature must range between
0°C e +40°C (for operating temperatures below or above, contact the Montanari
technical office unless expressly agreed/authorised).
Assembly and installation must be carried out with great care by qualified and
trained personnel. The manufacturer cannot be held responsible for damage
caused by incorrect assembly or incorrect installation. Before starting work,
make sure that adequate lifting and handling equipment is available. All fixing
points specified by the manufacturer must be used.
! !
Check the rotating direction: the speed governor can be on car side or coun-
terweight side. The arrow on the governor (Fig. 6) must be in the engagement
direction of the safety gear.
6.1 Installation surface - Fixing
The speed governor is suitable for being used both with room or without room.
The installation surface must be uniform, level and horizontal. The levelling to-
lerance is 0.2 mm. The installation surface must be rigid and robust enough to
withstand the forces involved.
Pay special attention to prevent shocks to the governor.
Place the unit on the installation surface and secure it. Do not force or hit the
fixings to position them; this could damage the governor.

FIXING: The speed governor must be fixed checking its vertical direction with
a bubble level or a lead wire.

MAX. ALLOWED SLOPING: The speed governor must be installed so that the
rope runs parallel in the pulley groove. The rope max. recommended sloping (A)
is ± 0.50°.

6.2 Installation of ropes
The speed governor only works in a perfect way if rope and tension device are
correctly installed.
1. Gather the rope close to the governor and thread one head through the
governor towards the safety gear levers.
2. Connect the first rope attachment to the same rope and secure it to the
safety gear lever.
3. Install the tension device following its installation instructions.
4. Connect the second head of the rope - passing through the tension device
- to the rope attachment and then to the safety gear lever.
