Our desks comply with CE marking and all European directives for machinery.
One of the safety directives we adhere to is that you have to be in physical contact with the control switch in order for the desk to move.
Cheap Chinese imports often have the feature of a 'one touch' switch, enabling you to press the switch once and leave the desk to move to its pre-set position, (whether you are in the room or not) this is specifically not approved by EU/UK law and could potentially result in injury, especially to pets and children.
Our anti-collision sensor operates in both directions and is actually an overload sensor, so when the desktop hits something solid, the sensor in the control box trips the current immediately. It doesn’t operate when hitting something soft like a chair, only when the desk comes to a dead stop. This is the standard 'anti-collision' device found on the majority of electric height adjustable desks and is really a safety cut-out on collision, rather than collision avoidance.
The main control box has a number of clever protection devices within it, mainly to protect the electronics from 'dirty' electricity, voltage spikes, surges and harmonic distortion.
Although the safety cut out rarely triggers, when it does, it will partially shut the desk down for safety. You'll know if the desk has gone into 'limp-home' mode if the desk will only allow you to lower it (at about half the normal speed) but you get no response when pressing the up button.
To reset the desk when it is in safety shut down state, ensure the space under the desk is totally clear, press the down button until the lowest point is reached, release your finger from the button and then press the down button again for at least 10 seconds, until you hear a click and see the whole desk jig down and up a small amount. This has now reset and you're good to go.
