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 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 LED1 on the receiver is red and slowly flashing (approx. 1 Hz) on Leuze MLD 500 Security Sensors?
If LED1 on the receiver of Leuze Security Sensors is red and slowly flashing (approx. 1 Hz), it indicates an external error. Check the connection of the cables.
How to troubleshoot if the LED at the transmitter per light axis is off on Leuze MLD 500 Security Sensors?
If the LED at the transmitter per light axis is off on Leuze Security Sensors, it is because the transmitter beam is inactive or there is no supply voltage. Check the power supply unit and the electrical connection. If necessary, replace the power supply unit.
What to do if Leuze MLD 500 Security Sensors show error E30, E31, E32, or E33?
If the Leuze Security Sensors display error E30, E31, E32 or E33, it indicates an issue with the feedback contact of contactor monitoring. Check the functionality of the contactor and its cable connections. If necessary, replace the contactor.
What to do if Leuze MLD 500 Security Sensors display error E27?
If the Leuze Security Sensors display error E27, it indicates a short-circuit in the local interface between the start button and MS1 (pins 4 and 5). To resolve this, check the wiring.
What to do if Leuze MLD 500 Security Sensors display error E24?
If the Leuze Security Sensors display error E24, it means the start button on the connector plug is connected to 0 V. Check the wiring to correct this.
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 MLD 500 Security Sensors display error E14?
If the Leuze Security Sensors display error E14, it indicates undervoltage 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.
