3.2 Functional Description

The overspeed governors type 7/8/9 are safety components type approved inaccordance with EN 81. They serve for engaging the safety gear and switching offthe lift system at overspeed in upward or downward direction. The release speed(Va) has been factory set and sealed in accordance with EN 81-1.The governor works according to the pendulum principle.The safety switch on the overspeed governor is actuated at a speed of: Vn up to 1.00 m/S simultaneously with the mechanical safety gear



4/16


Version 07.02

Vn above 1.00 m/s max. 10% below the mechanical safety gear as a pre-cutoff

and the lift systems safety circuit is interrupted.The engaging force required fort he safety gear or brake system respectively isachieved by means of an according tension weight.The overspeed governors may be used for triggering safety systems on the cabin,counter-weight or balance weight.

The tensile force generated in the governor rope by the release overspeedgovernor must equivalent to the higher of the following values:a) the double of the force required to engage the safety gear orb) 300 N

The governors release speed on the counter-weight is set 10% higher thanthe one of the cabin.

A slack rope switch must be installed on the tension weight.

Description of the triggeringBy means of a pressure spring which is guided by a bolt and acts on the pendulum,the pendulum pulley s pressed to the cam shape of the governor wheel. If the pre-setrelease speed Va is exceeded the pendulum pulley is taken off the cam shape by thecentrifugal force.This initiates the following process:

The stop pendulum is moved so far that its safety catch engages in thecam on the governor wheel.- At Vn up to 1.00 m/s the safety switch is triggered by the stop platetogether with the mechanical gear.- At Vn above 1.00 m/s the pre-cutoff is triggered by the switch cambefore the mechanical gear.

The governor wheel is blocked. The governor rope is clamped due to the v-formation of the rope groove. This clamping causes the safety gear on the cabin or counter-weight to be

pressed in.

! The governor must not be commissioned until the lift system has been checkedand any causes of malfunctions have been eliminated by expert personnel.Resetting is made: Systems of up to Vn 1.00 m/s: by travelling the lift with the return control. Systems above Vn 1.00 m/s: by manually or electromechanically resetting the

pre-cutoff and subsequent travelling of the lift with the return control.The governor is then in operating condition again.

6 Installation Instructions

BODE Overspeed Governors may be installed in one of the following locations:

1. In the machinery room On the floor On the sub-structure

Installation with screws and dowels (not included) on the floor. The customer has toprovide a clean and even seating for the governor or the sub-structure. The governormust not be deformed when tightening the mounting screws.

2. In the pit head With console on the guiding rail On the pit ceiling On the pit wall

The console for the rail fastening is installed by means of clamping brackets. The typeplate has been applied suited for this type of installation.

!For governors with lateral tope outlet or suspending types, the settings have to bemade accordingly ex works. The type plate has been applied suited for this type ofinstallation.

3. On the pit floor On the tensile weight with guiding stand

The tension weight is vertically mounted to the floor with screws and dowels (not

included). A clean an even seating is to be provided.

! The governor is to be protected against intruding of foreign objects between camwheel and rope (EN 81-1). A suitable cover is available.The rope outlet is to be aligned vertically from the governor to the rope mounting of thesafety gear. The wrap angle must always be 180.When installing the governor in the machinery room or pit head, a suitable tension pulleymust be used.

7 Commissioning

Before commissioning, the following has to be checked: Operability of the governor Operability of the attachments Mounting of the governor Wiring of the safety switch Installation and wiring of additional parts. Unobstructed movement of the tension weight. Wiring of the slack rope switch. Vertical rope outlet.

!For testing purposes the governor has to be pressed in jerkily as otherwise therequired frictional resistance is not achieved. At low speeds the safety switch will bereliably actuated when the release speed is reached.

Version 07.02

8 Maintenance

The maintenance is to be made together with the lift system maintenance and is limitedto the following:The free movement of all movable parts is to be checked.Cam wheel, rope groove, and O-ring on the pendulum pulley are to be inspected fordamages and wear.The safety switch and additional parts are to be checked for their proper functioning.

Should the rope groove be run in in direction of the rope seat groove, the governor doesnot need to be replaced as it features a blank die (EN 81-1; EN81-2). The governor is tobe replaced if the blank die is less than 3 mm.

9 Repairs

As the governors release speed has been factory preset, an on-site repair is not possible.In case repairs or re-settings are required, these must be either made at themanufacturers or the governor is to be replaced. In case of repairs BODE gladly providesa corresponding governor for the repair period. Replacing the governor does not requirethe governor rope to be loosened.The warranty becomes void if seal on the adjustment nut or the colour sealing on thesafety switches are damaged.

10 Description and Wiring of the Safety Switch

10.1 Safety Switch 1563 (without arrest)

Switch 1563 is standard on governors designed for a nominal speed of up to 1.00 m/s. Itcomes without snap-on contact and the NCC is automatically closed when turning out ofthe gear. It is triggered by the dent in the stop plate.

13/16


Version 07.02

Note on InstallationThe remote release unit is pre-fixed in its position by means of a heavy-duty dowel pin.For installing it the holders M8 screw is put in the right hole of the stop plate andtightened with a torque of 10 N/m.Then, wire the unit. The supply voltage is 230 V AC, 50 Hz. The coil connection is pre-mounted with a 0.75 qmm pigtail. Test the operability of the unit and, if need be,readjust the FA.Governors with a FA always include the safety switch 1563 without snap-on contact. Incase, a pre-cutoff is required, switch 1489 or only switch 2239 is to be additionallyinstalled. Switch 1489 has to be bridged and manually reset after actuating the remoterelease unit and engaging of the governor.

!When retrofitting the governor with a remote release unit modifications have to bemade. A dent has to be filed on the switch cam so that the remote release unitscone presses down the pendulum. Laterally, the remote release unit has to be put in

the right position. The operability of the unit is to be tested. When actuating the remote release unit the max. ED of 15% must not be

exceeded. The remote release units switch is to be clearly marked by means of a

warning sign.

11.2 Governor with Anti-Creep Protection (AS)

The governor can be equipped with an AS. The AS provides for several functions.

Functional description:A magnetic coil including push rod is additionally mounted on the governor. During the

controlled cabin movement, the magnetic coil is excited and holds the push rod in its endposition. The stop pendulum can swing freely. When the cabin comes to a halt themagnetic coil goes dead and drops out after a delay period preset at the time relay.Depending on the position of the cam disc the magnetic coils push rod is pushed againstthe switch cam or slides over it. If the cabin now starts moving due to overloading orother reasons, the push rod keeps the stop pendulum in release position. The cam wheelis blocked and engages the safety gear. The safety circuit is interrupted by the switch onthe AS.Depending on the respective position of the stop cam to the stop pendulum the releasedistance varies between 9 cm and 25 cm.

Version 07.02

Functional description when used to secure the installation:With lift systems where the drive unit is installed in the pit the AS may serve as a safetydevice during installation. When opening the lower lift door for maintenance works in thepit, the magnetic coil goes dead and drops out.

Functional description for securing when enlarging the cabin without modifying itsnominal load:If the cabin is enlarged without modifying its nominal load the AS in combination with aload weighing unit can be activated when exceeding the nominal load. Sinking andfurther travel of the cabin is then prevented by the safety gear.

Functional description when used to prevent from overtravel:The AS may serve as a safety device if the safety space is short. For this, a contact hasto set the AS voltageless when reaching the safety space so that the governor is blockedand the safety gear is engaged.

Notes on Installation:The AS is supplied unattached together with the governor. For installing it the M8 screwof the AS holder is inserted in the right hole of the stop plate. Now, the 4 mm split pin isinserted in the hole in the holder and thereby fixed. Tighten the holder firmly with thenut. Wiring is to be made in accordance with the wiring diagram.Wiring diagram

! When retrofitting the governor with anti-creep protection modifications are required. Adent must be filed on the switch cam so that the coils cone presses the pendulum down.Laterally, the anti-creep protection unit has to be set in the correct position. Theoperability of the unit is to be tested. The holder of the anti-creep protection is to betightened with a torque of max. 10Nm .

When installing the anti-creep protection no remote release unit can beadditionally installed. However, the anti-creep protection may additionally serveas remote release unit, if it is set voltageless for this purpose.

The switch for the remote release function is to be clearly marked with a warningsign.

The AS should be battery buffered as the governor would otherwise be blocked inthe event of a power failure.

11.3 Incremental Encoder Attachment

An incremental encoder can be mounted to the governor, the tension or diverter pulley.For this purpose, the tension or diverter pulley must feature a V-groove. Retrofitting aencoder attachment is not possible.

!Take care to use tension weights suited for the respective governor type.

When sliding on the pinion take care that the set screw does not extend intothe borehole.

Tighten the toothed belt only slightly.

12. Tension weights

Different tension weights can be used for operating the overspeed governor. The type oftension weight depends on the mounting type. For all tension weights a slack rope switchis supplied.

12.1 Tension weight for mounting on the guiding rail; stopping in downwards directionOrder number: 580 031 (300) / 580 034 (200)For this tension weight a shifting bracket for mounting on the guiding rail is required. Thetension pulley is to be mounted in a way allowing for sufficient play below the tensionpulley so that the slack rope switch can be safely switched and shut down the lift systemin case the governor rope is stretched or tears. The tension pulley is to be protectedagainst down falling objects.

12.2 Tension weight for mounting on the guiding rail; stopping in upwards direction

(Order number: 580 160 (300) / 580 161 (200)For this tension weight a shifting bracket for mounting on the guiding rail is required. The

shifting bracket features a preventer mechanism for stopping at upwards travel. Thesleeve of the preventer arm has to be loosely shifted over the grooved bolt. The armloosely rests on the tension pulley holder. All parts must be free-moving.The tension pulley is to be mounted in a way allowing for sufficient play below thetension pulley so that the slack rope switch can be safely switched and shut down the liftsystem in case the governor rope is stretched or tears. The tension pulley is to beprotected against down falling objects.

12.3 Tension weight with governor or diverter pulley mounted on the pit floor

There are two types of guiding stands to be distinguished: tension weights with a singletype guiding stand with integrated diverter pulley and a duplex type guiding stand. Both

are suited to be employed with a duplex safety gear. If the governor is mounted directlyon the tension weight, a heavier weight is to be used. The guiding stands are to be
