Intended use
MonoControl CS is a safety gas pressure regulator for caravans and mo-tor homes. The gas pressure regulator ensures a uniform output pressure of 30 mbar with a permissible inlet pressure range of 0.3 – 16 bar. The integrated crash sensor (CS) interrupts the flow of gas in the event of an accident with directly acting deceleration of 4.0 g ± 1.0 g. The MonoControl CS gas pressure regulator with safety valve is a single-stage gas pressure regulator. If the gas pressure regulator is not working properly, for example due to dirt or other foreign material on the valve, the safety valve opens and blows off to a pressure of 110 bar. Using the MonoControl CS in closed rooms (e.g. at home), on boats or in EX Zone 0 (e.g. tankers) is prohibited. The national regulations must be observed if there is a possibility of it being used in mobile homes. Its use in mobile homes is prohibited in Germany.
An automatic PRV safety device integrated in the MonoControl CS with limited flow protects the connected consumers against impermissibly high pressure. As soon as an impermissibly high pressure arises on the output side, the PRV opens and blows out the overpressure into the air. The PRV closes automatically after the pressure is reduced. = Pressure Relief Valve MonoControl CS must not be used for commercial purposes.
Safety instructions’
- Do not connect any electrical appliances or other potential ignition sources if you can smell gas or if there is a leak in the gas system. Close the cylinder valve, have the gas system repaired by an expert immediately and do not open the valve in the meantime.
- The use of upright gas cylinders from which gas is extracted in the gas phase is mandatory when operating the MonoControl CS gas pressure regulator. Gas cylinders from which gas is taken in the liquid phase (e.g. for forklifts) must not be used, since they would result in damage to the gas system.
- A gas filter must be installed upstream of the gas pressure regulator inlet to provide reliable protection against dirt/oiling. A set of operating and installation instructions is supplied with the gas filter.
- A high-pressure hose with hose rupture protection (HRP) is mandatory for connecting the gas cylinder to the gas pressure regulator or gas filter. For this, Trauma provides the necessary high-pressure hos-es with the most commonly-used connection variants for European gas cylinders (see www.truma.com).
- In normal conditions of use, in order to ensure the correct operation of the installation, it is recommended that this device is changed within 10 years of the date of manufacture. National regulations must be observed. The operator is responsible for this.
Operating the gas system while driving:
- The appliance manufacturer’s instructions must be followed before operating a liquid gas appliance while driving.
- For heating, while driving, regulation (EC) No. 661/2009 and the binding UN/ECE regulation R 122 stipulate a safety shut-off device for motor homes and caravans.
- The MonoControl CS gas pressure regulator satisfies this requirement.
- Installing a safety shut-off device such as the MonoControl CS gas pressure regulator with appropriately configured gas installation means that a type-tested liquid gas heater may be used in line with the aforementioned regulation while driving throughout Europe. National regulations and rules must be followed.
- For vehicles manufactured before 01/2007 there are no restrictions for operating the gas system while driving *. Operating instructions Except for France:
- In France, operation of a gas system while driving is only permitted in type-tested vehicles with first registration as of 01.01.2007. In older vehicles the operation of the gas system while driving is also non-permissible in combination with a safety shut-off device.
- Gas cylinders that are not connected to the gas installation must be closed at all times and provided with protection caps. Connect-ed gas cylinders are considered to be operating materials and not hazardous materials (ADR exemption in accordance with sections 1.1.3.1 and 1.1.3.2 e).

Crash sensor
The crash sensor has a reset button, the position of which indicates its
status: “Ready for operation” position (Figure 2a) or “not ready for
operation” position (Figure 2b).
To reset, press the yellow reset button (7) firmly, turn it slightly clock- wise, hold it for 10 seconds and ensure that it stays in the “ready for operation” position (Figure 2a). If the reset is not successful, use the Torx T20 (12) on the screw aid (11) to support the clockwise rotation.
Changing the gas cylinder
Use the included screw aid (11) to attach and remove the high-pres-sure hose
(4). It will help you generate the necessary tightening torque and will
prevent damage to the union that may otherwise re-sult from using an improper
tool.
- Close the valve (1) of the empty gas cylinder (2).–
- Remove the high-pressure hose (4) from the gas cylinder (2) and remove the clip-on adapter, if present.
- Attach the high-pressure hose to the full gas cylinder and fit the clip-on adapter, if present. Change the filter pad of the gas filter.
- Open the full gas cylinder’s valve (1).
- Press the hose rupture protection (figure 1a – 3) and if necessary the yellow reset button (7), turn it slightly clockwise and hold it for 10 seconds.
After any intervention, check the hose connection to the cylin-der valve for leaks (see “Checking for leaks in the high-pressure section”).
Hose change
Use the included screw aid (11) to attach and remove the high-pres-sure hose
(4). It will help you generate the necessary tightening torque and will
prevent damage to the union that may otherwise re-sult from using an improper
tool.
WARNING
Residual gas: No smoking, no naked flames!
- Close the gas cylinder valve (1).
- Unscrew the high-pressure hose (4) from the gas cylinder (2 / or the clip-on adapter) and from the gas filter / MonoControl CS inlet.
WARNING : When changing the hose, ensure that the seal provided with the hose (hose outlet – gas filter/regulator inlet) is correctly installed and not damaged.
We recommend that the flat gasket G 13 (part no. 50020-76300) be replaced every time the hose is changed.
- Screw the country-specific high-pressure hose (4) to the gas filter (5) /MonoControl CS inlet and to the cylinder (2 / or the clip-on adapter).
