The guide pulley is used to re-divert the rope towards the tensor placed in the pit. This pulley rotates whenever there
is movement of the car, even when the main pulley is locked. That is why we can assure that said pulley follows the
car movement perfectly.
This is very important as it allows us to know the position of the lift at any time, by installing an Encoder on said
pulley. (Dynatech offers its customers this possibility in the "Star Plus" governor).
Another important part of the Governor set is the rope tensing system. Below, the workings are briefly explained.
4.1 ROPE TENSING SYSTEM
The rope is anchored to the pit and ceiling of the lift well, by means of a tensing spring system.
The "detensing contacts" will be placed together with the anchorings. Said contacts must be connected parallel and,
in turn, to the installation security series line.
The aim of the two contacts is to detect rope breakage or detensing, as, in such a case, both springs will drive the
contacts. In the case of wedging, one of the springs will loosen and the other will tighten. As a result, therefore, only
one of the two contacts will open without modifying the series line.
Tensing is carried out by means of the "adjusting nut", as this will compress the spring to the maximum position
allowed by the driving plate.
Then apply tension to the rope using the nut.
Tighten the nut until the trigger plate touches the tensioner's U-support. See diagram below.
