6 Maintenance
6.1 General information
HYGROPHIL
®
4230 is as good as maintenance-free. The only maintenance
necessary during operation is to refill the water tank and add a surfactant.
Depending on the conditions of use, it may be necessary for the measuring
chamber and any filters installed to be cleaned periodically.
The water separator on the external reducing valve should be checked
occasionally. If necessary, this must be emptied and the filter must be
cleaned.
In rare cases when particular types of dirt occur, it is also necessary for the
gas sampling hose to be inspected and cleaned on a regular basis.
Particular attention must be paid to making sure that the entire air supply
system is completely leak-proof. There is always negative pressure in the
measuring chamber. Leaks cause leakage air to be inducted.
Note:
Even small quantities of leakage air seriously falsify the measurement
result. You must therefore make sure that the air supply system is
completely leak-proof.
Attention:
Check hoses, lines and connections periodically for leakages, wear and tear
or damage. Repair any parts that need repairing.
6.2 Testing the analogue outputs
With a precise mA-meter you can test the analogue outputs. For it you must
call up a test mode (press key
F7
). In this mode you can enter a current for
each analogue output. The entered value is to measure at the corresponding
output.
The following chart provides you with an overview of the structure of the test
mode.
