ELX1052, ELX1054 and ELX1058 32 Version: 2.0.0
LED Display
The ELX1058 has a signal LED for each channel, combining a green input LED with a red error LED. When
both LEDs are on, the result is an orange color - in this case both the input and the error LED are "on".
The following tables are assigned to the respective LED number of a channel.
The ELX1058 allows the software to invert the input signal of individual channels. Depending on the setting,
one of the following two tables applies to the interpretation of the signal.
LED indicators, if the signal of the corresponding channel is not inverted (default):
Input LED Error LED Meaning
off on Error detection: open-circuit on channel (I < 200 µA typ.)
off off Usual operation: NAMUR sensor on channel in non-conductive state
("0"; according to IEC 60947-5-6)
on on Error detection: short-circuit on channel (I > 6.3 mA typ.)
on off Usual operation: NAMUR sensor on channel in conducting state
("1"; according to IEC 60947-5-6)
LED indicators, if the signal of the corresponding channel is inverted::
Input-LED Error LED Meaning
off on Error detection: short circuit at the channel (I > 6.3 mA typ.)
off off Usual operation: NAMUR sensor on channel in conductive state
("1"; according to IEC 60947-5-6)
on on Error detection open-circuit on channel (I < 200 μA typ.)
on off Usual operation: NAMUR sensor on channel in non-conductive state
("0"; according to IEC 60947-5-6)
In addition to the channel-related LEDs, the ELX1058 also has a general error LED, which indicates an error
in the power supply (24 V). This LED is located at the top right of the LED prism.
