Rectification of the errors under points 1 – 4 (gas supply error)
The following action can be taken if an error occurs in the gas supply, for example abnormal loss of
calibration gas.
.
Action: Gas supply error rectification
Complete a tightness test by checking the entire gas route (from the
cylinder/pipeline to the device) using a gas detector.
Set the regulators and valves to the required values.
Disconnect blocked lines from the switched-off device and flush the pipeline with
non-flammable gas to remove any blockages and deposits not exceeding the
maximum pressure.
Rectification of the errors under point 5 (electrical supply and insulation errors)
The following action can be taken if an error occurs in the electrical power supply. The use of a
voltmeter is required to locate the error. If the device is not supplied with electricity or the supply
voltage/current is too low, the following effects may occur:
• The interactive screen is dark, the Status LEDs are off.
• The interactive screen is dark, the right Status LED flashes or is off.
Action: Testing the electrical supply
Check all switchgear and fuses outside the device and replace any defective parts.
Check the cable connection between the device and the electrical supply (no break in
the wiring). Ensure that a low-resistance electrical contact is established.
Reconnect the cores if necessary.
Check that voltage is being supplied to the inlet point and that the voltage is not
impaired or reduced by overload, insulation errors or defective components. Remove
or replace these components if necessary.
