What to do if Leuze MLD 500 Security Sensors display error U51?
If the Leuze Security Sensors display error U51, only one muting signal is active during a protective field violation, and the second muting signal is missing. Check the mounting of the muting sensors and the triggering of the muting signals.
What to do if Leuze Security Sensors display error E02?
If the Leuze Security Sensors display error E02, it means there is an overload on OSSD1. To resolve this, check the wiring or replace the connected component, thus reducing the load.
What to do if Leuze Security Sensors display error E03?
If the Leuze Security Sensors display error E03, it indicates an overload on OSSD2. To fix this, examine the wiring or replace the connected component to reduce the load.
What to do if Leuze MLD 500 display error E04?
If the Leuze Security Sensors display error E04, it indicates a short-circuit against Vcc at OSSD1. To resolve this, check the wiring and replace the cable if needed.
What to do if Leuze Security Sensors display error U54?
If the Leuze Security Sensors display error U54, it indicates a missing additional muting control signal (muting-enable). Check the connection of the muting sensor and the triggering of the muting-enable signal. Reconnect the muting sensor, if applicable, and activate it with a restart.
What to do if Leuze MLD 500 display error U56?
If the Leuze Security Sensors display error U56, the muting restart was canceled. Check the connections of the muting sensors and carry out a muting restart again if required.
What to do if LED1 on the receiver is green and slowly flashing (approx. 1 Hz) on Leuze Security Sensors?
If LED1 on the receiver of Leuze Security Sensors is green and slowly flashing (approx. 1 Hz), it indicates a weak signal due to soiling or misalignment. Clean the front screen and check the alignment of the transmitter and receiver.
What to do if Leuze MLD 500 display error E19?
If the Leuze Security Sensors display error E19, it means a foreign transmitter has been detected. Remove any foreign transmitters and increase the distance to reflective surfaces.
What to do if Leuze Security Sensors display error E15?
If the Leuze Security Sensors display error E15, it indicates overvoltage at the supply. To resolve this, select a suitable current source.
What to do if Leuze Security Sensors display error E01?
If Leuze Security Sensors show error E01, it means there's a cross connection between OSSD1 and OSSD2. You should check the wiring between OSSD1 and OSSD2.
