DuoControl CS is a safety gas pressure regulating system with automatic
switching for a two-bottle gas system and with crash sensor. The DuoCon-
trol regulating system automatically switches the gas supply from the pri-
mary bottle to the reserve bottle as soon as the primary bottle is either
empty or no longer ready for operation. The gas appliances may still con-
tinue operation. The DuoControl regulating system is suitable for all com-
mercial gas bottles with liquefied gas (propane/butane) and a pressure of
0.6 bar to 16 bar.
The DuoControl regulating system ensures a constant gas pressure for the
gas-operated devices, no matter which gas bottle is supplying the gas.
In the event of an accident, the crash sensor in the DuoControl regulating
system will interrupt the gas flow.
The gas bottles are connected via high pressure hoses. A hose break guard
prevents gas leakage in the event of a damaged hose.
The operation of gas-operated devices during the journey is permitted in all
of Europe if the vehicle is equipped with a gas pressure regulating system
with crash sensor and high-pressure hoses with hose break guard.

The DuoControl regulating system consists of a reversing valve (Fig. 122,4)
and a crash sensor (Fig. 122,5). The DuoControl regulating system is in-
stalled between the gas tubes (Fig. 122,3) with hose break guard
(Fig. 122,1). The knob (Fig. 123,1) on the reversing valve is used to select
which of the gas bottles is to be used as primary bottle and which is to be
used as reserve bottle.
The status of the gas supply is indicated in the inspection window
(Fig. 123,2):
Green: Gas is taken out of the primary bottle.
Red: Gas is taken out of the reserve bottle.
The operation with only one gas bottle is allowed but in this case the open
connection must be closed with a blind cover (Fig. 123,4).
The crash sensor blocks the gas supply in the event of a significant impact
(e.g. accident). The crash sensor is put into operation with the green reset
button (Fig. 123,3).
The hose break guard (Fig. 122,1) blocks the gas flow if the connected hose
breaks. The hose break guard must be activated by pressing the green but-
ton.
