Optional extras

Function programming
The option of configuring drive parameters (e.g. the stroke) individually using software and the related service tools, for drives fitted with PLP, BSY or BSY+ electronics.
BRV signal
Confirmation from the drive, via the control cable, that the drive has fully extended or retracted. When used with the AT 41 and ERM 44 modules, this signal is sent to the central building management system, to the modules themselves or to the locking drive. The BRV signal is not potential-free.
SGI signal (position reporting)
In combination with the D+H servo plug-in unit SE 622 or the BSY gateway BSY-GW-024-010-U, drives can be controlled with precise positioning.
Acoustic signal (corresponding to the protection class)
AS2 corresponds to “protection class 2” of the ZVEI risk assessment by means of an acoustic warning signal in the “CLOSED” running direction. AS3 corresponds to “protection class 3” of the ZVEI risk assessment: in addition to AS2, it stops the drive for 11 s with a remaining stroke of 28 mm.
SBU (bendable chain)
The drive chain with a rigid back bends in the direction of the hinges. The drive is fixed in place (it does not pivot).
SBD (bendable chain)
The drive chain with a rigid back bends in the direction of the hinges. The drive is fixed in place (it does not pivot).
