ACB (Advanced Communication Bus)

Enables direct bus communication between the controller and the drive for, for example, control with perfect positioning or drive feedback. Com‑

munication is via the open source Modbus protocol, and it enables the drive to be combined with an ACB‑capable control panel or enables it to be

directly connected to higher‑level controllers such as a building management system.

Audible signal (corresponding to protection class)

AS2 corresponding to “Protection class 2” in accordance with ZVEI risk assessment through an audible warning signal in the “CLOSED” running direc‑

tion. AS3 corresponding to “Protection class 3” in accordance with ZVEI risk assessment, in addition to AS2, stops the drive for 11 s with a remaining

stroke of 28 mm.

End position message (OPEN / CLOSED)

Drive feedback via an integrated isolated switching contact. This happens if the chain / rack and pinion has moved completely out or in.

BRV signal

Acknowledgement from the drive, via a control cable, to confirm that it has been completely extended or retracted. When used with the AT 41

and ERM 44 modules, this signal is sent to the central building control system, the modules themselves, or to the lock drive. The BRV signal is not

isolated.

BSY+ (synchronisation of drives)

In addition to providing the same synchronisation function as BSY, BSY+ enables different components in the window to communicate with each

other. For example, the chain drives, during synchronous operation, or the window and lock drives (e.g. FRA 11 BSY+ or VLD‑BSY+).

HS “High‑Speed”

In the case of SHEV, the high‑speed function is used for reliably reaching the defined end position in 60 s. In daily ventilation mode, the drive runs

quietly and quickly, as usual.

Mechanical adjustment

Drive option for adjusting the overall length or design (e.g.: centred chain outlet).

Function programming

Option for customised configuring of drive parameters (e.g. stroke) via software and associated service tools for drives equipped with PLP, BSY or

BSY+ electronics.

SBD side bow chain

Drive chain with rigid backing, bends in the direction of the hinge. Drive is fixed in place (not rotatable).

SBU side bow chain

Drive chain with rigid backing, bends in the direction of the hinge. Drive is fixed in place (not rotatable).

SGI signal (position reporting)

In combination with the D+H servo plug‑in unit SE 622, the drives can be controlled with perfect positioning.

SKS (closing edge protection)

Drive option, which enables an anti‑trap strip or presence detector to be connected directly to the drive (terminal resistor 5.6 kΩ).
