l need to use lov3 descend by 200 meters, is it ok ?

There is no distance limit when using a LOV3. We only recommend that you descend slowly, so as not to overheat your device. As steel heats up, it tends to become more slippery.

I would like to know the recommendations when blocking the slack of the rope when using the Lov2 to block a tyrollean rope.

In the note “ADD-170516-VPO-a-rope-tyro-diameters-Fr.E”, it is stipulated that in the case of a load over 200kg, it is necessary to block the slack of the rope.
Is a mule releasable knot 1m behind the Lov2, enough?

As a member of the Technical Commission within the SNGEA (National Union of Tree Climbers), I try to understand the best practices.

Fabrice Fortner , member of the Technical Commission at SNGEA / EGA

Thank you for this relevant and interesting question.

The answer: we specify nothing more, because it depends on the user’s appreciation and his risk analysis assessment.

The reason why blocking:

  • You risk jolts and therefore overloads and therefore slip,
    The tool must be used with relevant margins and safety factors.
  • The standard requires the tool to block at 300 kg with slack, free rope output, static, knowing that our tests validate the tool around 500 kg.
    The standard also requires the tool to be able to hold a tension of 1500 kg with a lock at the tool exit.
  • We therefore keep a coefficient of 5 for a blocked use at max 3OO kg.
  • We also keep a margin for surges of overload, without blocking, up to 200 kg.

As a result, for your case, the risk of moving a mule-type releasable locking knot that can slide and give slack, is that the slip gives a lowering effect to the load: very good for the tension, which will decrease , much less good with respect to the free space and obstacles. The closer you get to the blocking knot, the lower the risk. You are also allowed to block the rope (releasable or not) on another reliable element.

Is it possible to use the TAZ LOV2 as a replacement for the Petzl ASAP? Can both the descender and LOV2 as back-up be operated simultaneously safely, or should it be done alternately?
You can replace Petzl Asap by our device only you will have to manage its descent. 
When you use the LOV2 as fall arrest and when you operate the descender handle during the descent, we recommend that you pull the LOV2  alternately and to avoid holding it permanently. Indeed, the risk in case of a fall is to have a reflex to grasp the tool, and thus prevent its normal fall arrest operation.
In the case  you dont’t do it alternately, you will have to pull LOV2 fall arrester very lightly, with two fingers grabbing the opposite holes. How to do this properly is explained in our video series, available on Youtube and on our website. 

When using LOV 2 as a fall arrester, what type of lanyard should be used?Is there a limit on the length of the lanyard?

Any normalized lanyard, no limit of length. Length defined by risk assessment in each situation. Using it as descender, max length 40 cm. (see User Manual ) .

When using a LOV 2, what type of connector do you recommend?

Any kind of automatic and alloy made connector ( see user manual).

When there is a 2 persons load on the LOV2 ( rescue scenario), do I have to use a brake carabiner?

yes

When using LOV 2 as a fall arrester or a descender, do you accept the load of two people?

For fall arrester no, for descender yes, in exceptional scenarios (see additional rescue note ).

How to verify that my LOV2 device from the first series (n° S0116 xxxx)  is of an upgraded version ?
