What to do if hot steam escapes from GESTRA Measuring Instruments?
If hot steam escapes from GESTRA Measuring Instruments, immediately reduce the boiler pressure to 0 psi (0 bar) and verify the pressure before unscrewing the level electrode. Ensure the level electrode is only removed when the boiler pressure is at 0 psi (0 bar).
How to prevent burns from a hot GESTRA Measuring Instruments level electrode?
To prevent burns from a hot level electrode on GESTRA Measuring Instruments, always allow the level electrode to cool down before starting any installation or maintenance work. Only remove level electrodes after they have cooled down completely.
What to do if LED alarm 1 or 2 and Diagnosis LED 3 are illuminated on GESTRA Switch?
If the LED alarm 1 or 2 and Diagnosis LED 3 are illuminated on your GESTRA Switch, and pressing and holding down key 1 or 2 doesn't resolve the issue, it could be due to a malfunction in the processor or a stand-by fault. Refer to the operating instructions for the logic unit SRL and consider replacing the level switch. It could also indicate an internal voltage fault, in which case you should replace the level switch.
Why is the Diagnosis LED 3 flashing on my GESTRA Switch?
If the Diagnosis LED 3 is flashing on your GESTRA Switch, it may be due to interference voltage causing a malfunction, or the boiler earth may be without PE. To resolve this, provide screen and earthing, and connect the boiler with PE.
What to do if LED alarm 1 and diagnosis LED 1 are illuminated on GESTRA Switch?
If LED alarm 1 and diagnosis LED 1 are illuminated on your GESTRA Switch, and pressing and holding down key 1 doesn't resolve the issue, it could indicate a malfunction in the level electrode or level switch, faulty wiring, or a faulty measuring voltage. Check the wiring, measure electrode voltages, clean and, if necessary, exchange the level electrode, and exchange the level switch.
