i3GLIDE Extended installation and balancing instructions

This article is for those who require more specialised background information than provided in the supplied user manual and for troubleshooting the balancing of the counter weights.

📘 Instructions

1. the balancing weights that come with the Glide are just that: for balancing. Due to tolerances of the weight of display, boards and frame materials, and also to tweak to user preferences (e.g. more easy downwards movement), these balancing elements can be used. Not necessarily all of them.

2. The Glide uses a double pulley system to cut in half the force needed to slide the display up or down.

3. The initial force needed to start the movement is always higher, as this is a law of physics. The more heavy that the display is, the more this effect counts. Still, due to the weight of the display, and despite being perfectly balanced and the use of a double pulley system, one will need more force to start to move an Interactive Display, than a normal traditional whiteboard. An Interactive Display can easily be 4x the weight of a traditional whiteboard.

4. The force needed to initialize the movement is initially about 100N and drops quickly to 30N or less after the movement starts . The norm EN14434 allows 105N in case of operation by hand. If the force is higher than that, the installation is considered ‘defective’ and needs correction.

5. We specialized calibrated tools to do the measurements in the factory. This tool can record the occurring peak forces as well as the mean forces. This is a very expensive tool! Alternatively, one can use a simple digital hanging scale that will do an approximate job for a lot less. Or, if you want a quick and dirty check if the requirements are met, then just attach 5 pieces of 2Lbottles of water to the handle, and see if it starts to move down. If the upwards movement has about the same feel, it is roughly within specs.

6. If a Glide system needs excessive force, the first thing to do will be to check the installation: if the columns are not perfectly vertical and aligned to each other in the front and side plane, then too much friction will occur. If the columns are not at the correct distance to each other, too much friction will occur as well. To test this and to try to correct this, the installer can loosen all fixtures and brackets and slowly move the display up and down. If there is an improvement, the system can ‘settle’ itself. Try to fix it in the new position. This only works when minor corrections are needed.

7. Also check if the frame on which the display is hung, is perfectly parallel. To do so, measure the diagonals. They should be the same within 1.5mm. Otherwise, try to correct.
