The servo plug-in unit SE 622 is used as interface
module between Building Management System
(BMS) or Central air conditioning plant (ZLT) and
D+H Smoke extraction and vent system RZN
43xx-E. The unit is to convert an analogue preset
value from the BMS into a drive stroke between 0-
100% in conjunction with D+H drive with option
"-SGI". Opening width can be steplessly
controlled, depending on the BMS input value.
For the function of the SE 622,
are
additionally required to the drive with position
indicator for actual value feedback.
Cable connection BMS - servo plug-in unit:
- provide 2 wires Ø 0,8 mm per servo plug-in
unit.
- one group plug-in unit is required per servo
plug-in unit.
- all connected drives must have the same
stroke.
- Safe closing of all drives when the setpoint
value from the BMS < 5 %.

Function:
Power failure-synchronisation
Triggering is effected as analogue setpoint value
via a 2-wire circuit. Either current-controlled with
values 0 - 20 mA, 4 - 20 mA or voltage-controlled
with values 0 - 10V. This corresponds to an
opening width of 0 - 100%. BMS input is
electrically isolated from the D+H-system
voltage.
The servo plug-in unit compares the setpoint
value from BMS with the actual value of the drive
and operates the drive to the desired position,
using the group plug-in unit. The servo function
can be switched off at the plug-in unit or by
remote control. Then the drive group can be
manually opened or closed by built-in vent
buttons or external vent buttons LT. The actual
value can be checked on a digital display on the
plug-in unit. The feedback to the BMS is provided
as analogue signal with values 0 - 10 V.
The servo function is overridden in the case of an
alarm from the Smoke and heat vent system. The
function “Master CLOSE“, e.g. in the case of rain
or a timer, has a higher priority than the servo
function and can be activated by DIP-switch (5).
The drives are automatically closed in the case of
wire break or short circuit on the setpoint value
wire.
After a power failure with the DIP switch No. 6
switched to ON, the drive will go to its position
CLOSED in order to be able to open again up to
the given value (e.g. 50% from the BMS) in the

OPEN direction, after the power failure has been
resolved.
The drive is controlled
automatically, so there is a potential source of
danger of pinch or shear points in the area of the
drive. With the factory-setting “OFF“, the drive
must run to position „CLOSED“ after a power
failure, via a vent button with visual contact to the
drive. For this, the automatic operation of the
servo plug-in unit SE 622 must be switched OFF
beforehand.
are
equipped with a digital pulse generator. The
servo plug-in unit must know the total pulse
number of the drive so that the setpoint value
from the BMS can be equally distributed over the
opening width. For this purpose, there is an
operating mode “Measure opening width“.
The clamps 8 + 9 (-N + Auto I/O) must be bridged
on the plug-in slot of the servo plug-in unit for the
activation of this operating mode.
Please note:
D+H Drives with the option "-SGI"
This operating mode is activated with reset button
(S4). The button (S4) must be activated for at
least for 7 seconds.
