General
The DC control unit GS2 is a power supply unit for controlling 24V Becker DC drives.
The performance figures for the control unit are tailored to these drives. If the trans-
former is overloaded, a thermoswitch in the transformer will deactivate and will only re-
activate when the control unit has been disconnected from the mains.
Parallel operation with the DC control unit GS1 is possible, i.e. the drive is powered by
DC control unit GS2 when mains voltage is present, and is automatically switched to
GS1 battery mode in the event of a power failure. The tubular drive is powered by the
supplied voltage at terminal A.
The control unit is encased in a splash-proof housing as a compact unit.
Explanation of pictograms
CAUTION CAUTION indicates a hazardous situation
which, if not avoided, could result in injury.
ATTENTION ATTENTION indicates measures that must be
taken to avoid damage to property.
Denotes user tips and other useful information.
Warranty
Structural modifications and incorrect installation which are not in accordance with
these and our other instructions can result in serious injuries, e.g., crushing of limbs.
Therefore, structural modifications may only be carried out with our prior approval and
strictly in accordance with our instructions, particularly the information contained in
these Assembly and Operating Instructions.
Any further processing of the products which does not comply with their intended use is
not permitted.
The end product manufacturer and fitter have to ensure that all the relevant current
statutory, official and, in particular, EMC regulations are adhered to during utilisation of
our products, especially with regard to end product manufacture, installation and cus-
tomer advice.

Safety instructions
General information
•Only use in dry rooms.
•Only use unmodified original parts from the control unit manufac-
turer.
•Keep children away from control units.
•Observe all pertinent country-specific regulations.
Caution
•Risk of injury due to electric shock.
•The limits given in the technical data must not be ex-
ceeded.
•Connections to the 230V mains must always be estab-
lished by an authorised specialist.
•Disconnect the connecting cable from the power supply
prior to assembly.
•Always comply with the regulations of local energy sup-
ply companies as well as the VDE 100 provisions for wet
and damp rooms during installation.
•Keep people out of the system’s range of travel.
•If the system is controlled by one or more devices, the
system’s range of travel must always be visible during
operation.
•When connecting the control cables (protected extra-
low voltages), only use cables with sufficient electric
strength.

Intended use
The control unit type in these instructions is intended for the supply and control of
24VDC tubular drives from the company Becker-Antriebe, which are used for sun pro-
tection, roller shutters, roller doors and similar blinds or shutters.
The connection of external devices must be carried out in consultation with specialist
retailers.
Installation
Caution
•Before installation, the control unit must be checked for
any damage sustained in transport or elsewhere. Dam-
age to the interior of the control unit may lead to consid-
erable consequential damage to the control unit and
jeopardise the safety of the operator.
•It must be ensured that the control unit is installed dis-
tortion-free.
•During assembly, it must be ensured that the cable
glands are pointing downwards.
•Any unused cable entries must be closed off by appro-
priate means in order to maintain the degree of protec-
tion of the housing.
•The cable entries must not be exposed to any mechan-
ical load, in particularly tensile loads.
•The mains plug must be clearly visible and accessible
from the control unit.

Opening the control unit
Installation on the wall
Fix the control unit to the wall with the holes provided for this purpose in the corners,
using 4 screws (max. screw head diameter: 7.5 mm) that are suitable for the nature of
the wall.

Electrical connection
Battery connection
At terminal A and 0V, power can be supplied either by DC control unit GS1 or by battery.
In the event of a power failure, the voltage at terminal A will be used.

Operation
The green LED serves as a control for the 24 V supply voltage.
The red LED indicates impermissibly high generator operation.
If the tubular drive is powered at over double the rated
speed, the voltage will increase to over 50 V, which will be
indicated by the red LED. This operating situation must be
avoided by means of design-based measures.
As the load on the tubular drive increases, the transformer voltage and the duty cycle
decrease.
