M1, M2 – INLET GAUGES
Each regulator R1 and R2 is equipped with high pressure gauge. These gauges show pressure
in the left and right collecting pipelines. If the product is equipped with contact gauges then
these gauges send information about pressure to the alarm system.
EN
T1, T2 – PRESSURE SENSORS
Pressure sensor is installed in each pressure regulator. Main function is to check a leakage on
reserve side and sends information to the alarm. When leakage on reserve side is detected by
pressure drop then alarm starts inform the technical personal. Variant with the transmitters send
information about pressure to the alarm unit.
5.2. LOW PRESSURE SIDE OF THE MANIFOLD:
S1, S2 – SAFETY VALVES
The manifold contains two safety valves on each side. When the outlet pressure increase up to
pre-set limit, the safety valve activates and gas is purged out. According to the version can be
equipped with safety valves with manual drain.
P1, P2 – PLUGS FOR SERVICING PURPOSES
Instead of these plugs (G1/4") an external low pressure gauge or other device can be used to
check the manifold parameters, such as outlet pressure or closing pressure.
E1 – PURGE PIPE FROM SAFETY VALVES
Purge pipe from safety valves have external dimension 10 mm. The purge pipe must go outside
of the manifold room as is described in installation standard.
V5, V6 – SERVICE VALVES
The manifold contains two service valves. These valves are only used for the service. It is not
allowed to operate the service valve with exception of trained service technician. Using these
valves is possible to service the manifold without interruption of the gas supply.
T3, T4 – PRESSURE SENSORS
Pressure sensor installed in the outlet block to the slot with marking LP sends information to
the alarm about empty of supplying side. Pressure sensor installed in the slot with marking HP
sends information to the alarm about too high outlet pressure. Variant with pressure transmitter
has only one sensor and other side is sealed only by a plug. Transmitters send information
about pressure to the alarm unit.
M3 – OUTLET GAUGE
Outlet block is equipped with outlet gauge. The gauge shows outlet pressure of the manifold
that is supplied to the stabilizer. If the product is equipped with contact gauge then the gauge
sends information about preset pressure to alarm system.
V10 – OUTLET SHUT OFF VALVES
Gas supply to the hospital pipeline system from the manifold unit is possible to close by outlet
shut off valve.
T5, T6 – MICRO SWITCHES
The manifold contains two micro switches that control the lever position. When the lever is in an
incorrect position Gas Alarm informs the technical personnel.
O1 - OUTLET CONNECTION
Outlet connecting must be soldered to the pipeline. Outlet connection is equipped with male
thread G1/2.
L – LEVER
Manual lever is control part of the manifold that makes it possible to decide which side is an
operational and which side is a reserve one. When the manual lever is in upper position left side
is the operational and right side is as the reserve. When the manual lever is in lower position
right side is the operational and left side is as the reserve. The MM40 semiautomatic medical
manifold can be delivered with HP accessories. The accessories contain parts for connecting
gas cylinders. Basic parts of accessories are in picture bellow.
