1.4.3. Switches
Safety gear electric safety device [5.6.2.1.5]:
D4N-4132. IP67. AC15 (240V/3A) / DC13 (250V/0.27A).
Monitoring of activation shaft
safety switch: D4N-4132. IP67. AC15 (240V/3A) / DC13 (250V/0.27A),
Monitoring of suction cup:
microswitch:
Monitoring of reset coil shaft position
microswitch:
[2] only for PRT83.2.1500/1
[3] only for PRT83.2.1500/2 with coil shaft decoupled from the sliding carriage
1.4.4. Environmental operating conditions
The equipment supports the operating range:
1.4.5. Delays
The delays measured between the opening of the holding coil supply and detection of the roller in the actuation
position are less than 100 ms.
1.5. Conditions and remarks
1.5.1. Each safety gear of the car's safety gear set, has an individual activation system as described in section 1.4.1 and
1.4.2
1.5.2. The activation means is designed to be used together with an electronic overspeed governor (encoder), which
must be designed according to SIL 3 integrity level.
1.5.3. The activation means is designed to be used exclusively with safety gears type DYNATECH's ASG UD for
downwards & upwards activation, according to certificates:
ASG-100UD, ASG-65UD, ASG-120UD, ASG-121UD
ASG-221UD
Note. The measurement of the required activation force is for these devices.
1.5.4. The force that the activation system is able to provide is less than that stated by [5.6.2.2.1.1.d)] of EN 81-20 for the
tripping force of a conventional overspeed governor rope. This deviation of the standard requirement must be
considered by the NoBo assessing the integration of the electronic overspeed governor and the activation system
in the safety technical dossier of the elevator. The measuring of the force required for the activation of the safety
gear and that provided by the activation spring along its entire operating length shows that the safety factor is
always greater than 2, which is the minimum required by the same clause of EN 81-20.
1.5.5. Concerning what is said in 1.5.4, it is required the checking of the required force and activation force by the
manufacturer of 100% of the products delivered, in order to ensure the safety factor is always at least 2.
1.5.6. Concerning what is stated in [5.6.2.1.6.4] of EN 81-20, the activation operation is performed by mechanical means
due to the energy stored in the compression spring, while the holding is electrically operated.
1.5.7. The safety electric device as required per [5.6.2.1.5] of EN 81-20 is included in the activation assembly. The
electric device stated in 1.4.3 can be replaced by another of equivalent characteristics.
1.5.8. Each subtype has monitoring means for position of the activation cams. The device types stated in 1.4.3, can be
replaced by others of equivalent characteristics. These monitoring means must be used by the elevator controller
to decide when to put safely the elevator into motion, preventing unwanted performance of the safety gear, also to
know if the safety gear has been correctly retracted and keep it on position, etc. The proper connection of these
inputs to the controller is responsibility of the designer that integrates the system into the elevator.
