Tension produced in the connection between the driving bar and the governor:
–
Greater than 300 N
–
Pulley diameter: 200 mm
–
Overspeed contact.
Explained in Section 3.3.
-
Serial remote interlocking:
Explained in Section 3.2.
-
Other features:
Possibility of assembling an encoder to report the position of the car at all times. (Star Plus Model)
The governor has 3 engagement points, in this way the distance between two consecutive interlocking
points is limited to a maximum of 200 mm.
STAR overspeed governors will always be assembled with first quality bearings. SKF Explorer bearings
Possibility of mounting an anti-creep system (Parking System) that locks the overspeed governor when
there is no current.
Possibility of installing types of tensioners of greater versatility when mounting.
Option to install a rectifier for the coils
Can be downwards or bidirectional.
Possibility of ordering the pulley groove hardened
-
Safety gears with which it may be used:
All safety gears whose tripping speed can be reached by the overspeed governor.
Remark: For tripping speeds below 1 m/s (generally instantaneous safety gears) a specifically designed
version for low speeds will be supplied (STAR BV). This overspeed governor has the same dimensions
and technical features than the standard one.
For performance speeds between 0.35 m/s – 0.6 m/s the STAR LS limiter will be fitted and has a
DOWNWARDS system.
8 TYPE OF ADJUSTMENT.
Tripping speed adjusting is carried out by means of a regulating screw which tenses or detenses the centrifugal
system spring. When tensing the spring, the speed required to drive the centrifugal system will be higher. In this way,
tripping speed can be adjusted within the speed range.

INSTRUCTIONS FOR USE AND MAINTENANCE
Positioning of the governor on the sling can be varied: at the top, at the bottom, in a cross-sectional or horizontal
position... End location will depend on frame manufacturer's criteria. However, the marks and technical information
supplied for that purpose must be taken into account, so that the governor functions accordingly.
The frame manufacturer must provide for the positioning of an articulated driving system between the governor and
the driving bar. Depending on the distance between them, said system must bear the compression stress produced
by wedging without causing bending. For this reason, it is recommended to place the governor as close as possible
to the safety gear, so that the driving system is light, simple and does not send an inappropriate torque to the
governor.
To avoid unnecessary risks that may cause incorrect governor functioning, two basic criteria must be taken into
account: cleaning and monitoring for corrosion. There are moving elements in any governor that will carry out the
action of interlocking. Dirt accumulation in these elements can cause malfunctioning. It is of vital importance that both
the installer and the maintenance staff ensure that these elements are perfectly cleaned.
On the other hand, Dynatech governors have rustproof protection in all cases but it is important that the maintenance
staff determine the possible existence of a corrosive process that may affect any mobile part of the element and stop
its natural movement. This check will be carried out by visually inspecting the surface condition and by carrying out
a wedging using the remote interlocking system. The frequency of these inspections is at the discretion of the
