WEL F automation can be used on fireproof doors. For doors opening outwards, on the actuator side, the automation features an articulated arm. Wel FFor heavy duty applications. For fireproof doors.

Product Applications andRange Unique Facilities and Features

This automation is available in four differentversions: E, M, S and F. To make sure the door is closed even in the event of power failure, it is advisable to select an automation opened by a motor and closed by a spring, preferably motor-assisted, such as Wel S. This solution allows the door to be manually opened and closed by a spring. Sturdy, reliable and quiet, these automations have been designed to offer a versatile and fully featured product, suitable for heavy duty applications, even with very heavy door wings. Wel S uses the Brake system to control the closing and approaching speed even in the event of power failure. Wel E is not fitted with a Brake system, but features a simplified version, still able to control the closing operation. The new Wel offers a wide range or electronic,mechanical and special facilities to ensure its suitability for different operational requirements. A must in all demanding environmental conditions, such as external doors exposed to the wind and to the elements. Wel E and Wel SPractical, reliable and quiet. Packed with features. Electronic facilities Wel MSturdy and versatile, ideal for very heavy duty applications. Automatic facilities: -thrust limiter; -obstacle detector with adjustable thrust. Operating modes: -Push and Go; -electrically operated lock control modes:· normal mode (working current or “fail secure” - wing remains shut even in the event of power failure); · anti-panic mode (idle current or “fail safe” - wing remains shut only if power is available. In the event of faults or power failures, users can still exit the room);-electrically operated lock latching control:the operating speed may be increased when approaching the electrically operated lock to ensure correct latching operation;-electrically operated lock release control:an option may be enabled to ensure that the electrically operated lock is correctly released; -wind-proof facility.Wel release system may be controlled by using theTEL2 or DMCS remote control. The automation can therefore be adapted to different types of existing locks, to the features of the door (weight - strength - opening problems) or to environmental conditions (different indoor-outdoor pressures).Wel E is a “simplified” product and therefore doesnot include the faculties listed below: obstacle detector with adjustable thrust, lock type control (Wel E only controls the normal lock) and electrically operated lock release control. For light to medium weight doors, the Wel E is a simpler and more cost effective alternative to version Wel S. Wel automation features a FA limit switch, which allows the following operations to be carried out: WEL S, WEL M, WEL F: The limit switch is used to control the wing opening angle or, by changing the connection, to bypass safety devices for the last opening section. Using the FA limit switch is optional therefore, if the automation is fitted with a door stop and does not open towards a wall, its use is not required. For applications where the wing opens towards a wall, the limit switch bypasses the operation of the sensors mounted on the wing so that they “do not see” the wall as an obstacle. WEL E: This version does not feature an encoder; the FA limit switch is therefore used to slow down the opening action, regardless of whether a door stop is fitted or not.
