Mounting the gas sampling hose
In order for the HYGROPHIL unit to be operated, it is vital that the gas
sampling hose is mounted precisely. You should therefore observe the
following instructions.
Attention:
Before mounting the gas sampling hose, make sure that it is designed for the
same voltage as the unit. Please note that the gas sampling hose consumes
100 W of power per meter. Without additional measures, the maximum length
for the gas sampling hose is 12 m at 230 V and 6 m at 115 V!.

Mounting instructions
No condensed water can be collected during normal operation of the unit if it
has been installed and programmed correctly. However, there is a risk of
condensed water being formed during operating breaks and in the case of
irregular operating states (compressed air or heating switched off).
You should therefore position the gas sampling hose in such a way that no
condensed water is able to gather in a sagging arc to form a 'water sack' that
blocks the flow of air.
Even when the compressed air is switched on again later, this alone will not
be enough to remove such a water sack, making manual intervention
necessary.
The hose should run either at a slant from the extraction point to the
measuring unit or upwards in the form of an arc.
Any condensed water that is formed should be able to flow either to the
measuring unit or to the extraction point. You must check whether
condensed water is allowed to flow back to the extraction point.
If condensed water runs into the HYGROPHIL
®
H 4230 unit, temporary faults
in the measured values may result. This must be noted in the case of
connected closed-loop controls. The HYGROPHIL
®
H 4230 measuring unit
will not be damaged.
Attention:
During mounting, make sure that the bending radius for the gas sampling
hose does not fall below the smallest permissible value of 160 mm.he unit is
the last user in the PROFIBUS, the two jumpers must be closed.
Please also observe the following instructions with regard to positioning the
gas sampling hose.
Handling the gas sampling hose properly plays a key role in ensuring that it
remains fully intact for longer.
