Problem/cause
Remedy
Gas is released from the relief valve.
Impermissible increase in the outlet
pressure.
Close all valves immediately.
Have the pressure control panel checked immediately by the
manufacturer or an authorised specialist company.
The pressure regulator is making noises.
This indicates a defect.
Close all valves immediately.
Have the pressure control panel checked immediately by the
manufacturer or an authorised specialist company.
The pressure regulator is frozen.
This indicates that too much gas is
being drawn.
Reduce the amount of gas drawn or – if technically, chemically
and physically possible – add a heater to pre-heat the gas.
There is a leak.
This indicates a defect in a pressure
regulator component.
Close all valves immediately.
Have the pressure control panel checked immediately by the
manufacturer or an authorised specialist company.
The outlet pressure level is unstable and
is not adhering to the usual range of
variation. This indicates that too much
gas is being drawn.
Reduce the amount of gas drawn.
It is also possible that there is dirt in the inlet filter. In this case,
the pressure control panel must be checked by the manufacturer
or an authorised specialist company.
The inlet pressure or gas cylinder
pressure of the side indicated as the
reserve side by the position of the lever
is falling.
The reserve side is also supplying gas to the downstream process.
This could either be because too much gas is being drawn or
because the pressure regulator has a defect.
Reduce the amount of gas drawn. If this is not possible or if this
does not correct the problem, contact the manufacturer or have
the pressure control panel checked by the manufacturer or an
authorised specialist company.
