What does a calibration failure message on my Dräger Controller mean?
If you see a calibration failure message on the screen of your Dräger Controller, it indicates a potential fault with the remote sensor transmitter. Check and repair the transmitter wiring and recalibrate.
What to do if I am unable to transfer configuration to or from the Dräger Controller?
If you're unable to transfer the configuration to or from the Dräger Controller, this could be due to a lack of power supply to the controller or a fault with the interface unit (RS-232). You should check and repair the external supply and wiring. If the issue persists, check and repair or replace the interface unit.
Why is the Fault (F) LED illuminated for a single channel on my Dräger Controller?
If the Fault (F) LED is illuminated for a single channel on your Dräger Controller, it could be due to a transmitter wiring fault, incorrect loop current, a faulty transmitter, or a faulty input module. To resolve this: * Check and repair the transmitter wiring. * Recalibrate the loop current if it's incorrect. * Replace the transmitter if it's faulty. * Replace the input module if necessary.
What to do if Dräger Controller display screen shows: Under-range?
If the display screen of your Dräger Controller shows 'Under-range', it could be due to a faulty transmitter connection, incorrect loop current, or a faulty transmitter. You should check and repair the transmitter wiring. If the wiring is correct, recalibrate the loop current. If the problem persists, replace the transmitter.
What to do if Dräger Controller display screen shows: Over-range?
If the display screen on your Dräger Controller displays 'Over-range', the issue likely stems from a short-circuit in the remote sensor transmitter wiring or a fault with the remote sensor transmitter itself. To fix this, you should check and repair the transmitter wiring. If the wiring is not the issue, check and repair the transmitter.
What to do if there is water ingress in my Dräger Controller?
If there is water ingress in your Dräger Controller, it is probably due to a faulty seal. You should check and repair the cover sealing ring, cable entries, and the front cover information label.
What to do if the LED and display screen test fails on my Dräger Controller?
If the LED and display screen test fails on your Dräger Controller, the problem is probably a faulty display board. Replace the display board.
Why is the output signal too low on my Dräger Controller?
If the output signal is too low or will not reach 20 mA on your Dräger Controller, the load resistance may be too high. Reduce the load resistance.
Why is the output constant at 1 ± 0.3 mA on my Dräger Controller?
If the output is constant at 1 ± 0.3 mA on your Dräger Controller, it could be due to no signal from the input modules or a faulty output module. Check and connect or repair the ribbon cable. If the issue persists, replace the output module.
Why is the Power DC / LED not illuminated but the display screen is on on my Dräger Controller?
If the Power DC / LED is not illuminated, but the display screen is on for your Dräger Controller, the issue might be a controller supply fault or a faulty display board. Check and repair the external or internal 24 Vdc supply. If the LED still doesn't illuminate, replace the display board.
