General information prior to installation
1.1
Description and main functions
The basic function of this safety device is to detect
overspeed, open the safety circuit and trigger the
safety gear via governor rope - in one or both direc-
tions.
An additional function is also available for supervi-
sion of car movement with open doors (UCM).
Also the acceleration can be measured to engage
the safety gear in case of excessive acceleration -
even before tripping speed is reached.
A tension weight is needed to tighten the rope of
the governor.
The operating range is defined as follows:
EOS D 200mm
The rotary pulley movement is detected by sensors.
This information is derived by a two channel and
self checking safety electronics.
In normal run operation the solenoids are powered
on and do compress internal springs. If the safety
electronics detects any dangerous ride situation
(e.g. overspeed) then the safety circuit is opened
and the electric supply of the solenoids is switched
off. This causes the preloaded springs to expand.
Successively the plungers contact the rotating brake
discs. This mechanical contact causes the synchroni-
sation plate to twist and trigger the internal brake.
