Bircher CoverLine Safety Edges

Designed for Automatic Sliding Gates, Ideal for Platforms, Stages & Lifts
ColverLine Safety Edges are idea for sliding gate
Product Info

Bircher CoverLine safety edges have been developed especially for sliding gate applications, however they are an excellent choice for use on lifting platforms such as stages or on automatic trollies.  There are four sizes within the range from 45 to 105 mm tall, which are clipped into the size of the special flat aluminium mounting rail.

There is no better choice of safety edges, safety ribs or bump strips for sliding gates.  The side mounting feature of the profile attaches them securely to the sliding gate and owing to them being fixed on both sides, they also react to side impacts of a moving object.  This secure method of installation and the higher over travel figures makes them suitable for moving platforms, automated trollies and large industrial doors.

Bircher safety edges comprise three elements:

  1. The aluminium mounting rail, which is flat with side ears for the safety edges are fitted to the device you want to protect.  Important, please make sure that the fixing heads of the screws used do not press on the rear of the safety edge as this will give you false triggers.
  2. The rubber profile, this is the external part of the safety edge that holds the switching strip in position and depending on the size of the profile will determine the all-important over travel distance.  Typically, the bigger the profile the larger the over travel figure and the greater the protection.  Important, please check the figures below to choose the correct profile for your application.
  3. The switching strip or contact strip, this is the heart of the edge which when compressed provides the signal to the switching or safety units to show when the edge has been activated.

Safety edges are manufactured in two formats a “pass through” or “link” version with two cables and the “end-of-line” version with 8k2 terminating resistors.  Up to four edges (as recommended by Bircher) can be are wired together in series with each other with the 8k2 version being the last link in the chain.  The switching unit monitors the resistance of the series of safety edges, if any of the edges in the chain are compressed this will cause the safety relays on the switching unit to open, also if any of the cables in the circuit are damaged the unit will show this as a fault and the safety relays will be opened.

All our safety edges are manufactured to order at Motion29, typically in 1 to 2 days from receipt of your order.  While we have fixed sizes available via our website, we manufacture all edges to order and it is no problem to make them to the size that you require, so please give us a call on 01495 360022 if you cannot find the size you need.

Over Travel Figures:

ELE040/055A0J – 250N = 11 mm, 400N = 15 mm

ELE040/067A0J – 250N = 30 mm, 400N = 32 mm

ELE040/080A0J – 250N = 27 mm, 400N = 32 mm

ELE040/081A0J – 250N = 38 mm, 400N = 41 mm

ELE040/105A0J – 250N = 37 mm, 400N = 53 mm

Installation: CoverLine safety edges should be clicked into the fixing channel by pushing on each side of the edge.  Pulling or sliding the profile into the channel may result in damage to the mounting foot and invalidate the warranty.  Ensure the edge is flush with the mounting channel and the heads of the fixing screws are not pushing on the rear of the profile as both can provide false readings from the safety edges.  If you are not sure, please contact us for advice on 01495 360022.

It is important that the correct profile is used as the type, size and speed of your automatic system (platform, door, gate, etc.) all influence the stopping distance and the force testing results set out in the standards.

ELE040/055A0J – 250N = 11 mm, 400N = 15 mm

ELE040/080A0J – 250N = 27 mm, 400N = 32 mm

ELE040/081A0J – 250N = 38 mm, 400N = 41 mm

ELE040/105A0J – 250N = 37 mm, 400N = 53 mm
