The carrier shall be modulated using a 50 % duty cycle square wave signal.
As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does not represent actual modulation, it would be worst
case.
If the environmental conditions are appropriate, is possible to install the device verifying that:
The installation floor is leveled and strong enough to withstand accelerations and vibrations to which the device could be subjected
during use on the medical vehicle. It’s suggested the use of a backplate.
The medical gas supply system has been regularly serviced or, in case of initial startup, the periodic maintenance has been programmed.
Fittings, pipes and all means of connection used in the system, are built according to the specific applicable standards.
Verify that purchased tubes and fittings respect the same standard requested for the device.
Distances between other electrical and electronic devices are like described in this manual.
The positioning of the device does not cause any type of obstruction inside the medical vehicle.
The power supply has the characteristics described in this manual. The pressure and flow delivered from the medical gas supply system,
have the characteristics specified in this manual.
The device must be installed using the dedicated surfaces on the lower side of the main body. Other fixation devices are available upon
request.
Any other type of installation, precludes the safety and functionality of the device.
The device must be connected to electrical power supply and to a source of medical gas having the following characteristics:
Power supply
Medical gas supply
Voltage
12 V/DC
(-15% + 25%)
Pressure
From 280 to 600 kPa

AC/DC adapter:
Manufacturer: Mean Well
Model: GSM25B12
Input: 100-240VAC, 50/60Hz, 0,7-0.35A
Output: 12Vcc 2,08A, 25W Max.
The power cable supplied with the device, must be connected to the device
and at the other side must be connected to a cigarette lighter socket
installed inside the ambulance.
The connector is placed on the connections side of the device.
Screw the connector ring to the device with a torque of approximately 2Nm,
until the device is connected safely.
If the device has to be serviced, it should be disconnected from the power
supply, or unplug the cigarette lighter.
