Description
EV 90 Interlocking Double- Evolution Model
3.3
Technical Specification
An all welded steel rotor with straight arms runs in a phosphor bronze bearing at the top and is sup-
ported by a maintenance free polymer bearing at the base.
Entry and exit can be made by card reader, push button or any other type of control device specified
by the client at the time of order. All controls are housed within the unit, therefore NO separate
switches or control boxes are required. Control of the rotor is achieved by an electromechanical head
mounted within the top section and accessible by removing the access panel, featuring,
– A positive action lock which prevents two passages at one time.
– A self-centring mechanism to ensure complete rotation of the head to the reset/home position.
– An anti-backup device prevents reverse rotation when the head has moved more than 32° from
the reset/home position.
