5.1 Status and error displays
LED displays
The figure below shows you the LED displays (status and error displays) of the
DQ 16x24VDC/0.5A BA.The tables below explain the meaning of the status and error displays.
LED RUN/ERROR
Table 5- 1 RUN/ERROR status and error displays
LED Meaning Remedy
RUN ERROR
Off Off
Voltage missing or too low at backplane bus. • Switch on the CPU and/or the system power
supply modules.
• Verify that the U connectors are inserted.
• Check to see if too many modules are inserted.
Flashes Off
Module is starting up. ---
On Off
Module is ready.
Flashes Flashes
Hardware defective. Replace the module.
LED PWR1/PWR2
Table 5- 2 PWR1/PWR2 status display
LED PWRx Meaning Remedy
Off
Supply voltage L+ too low or missing. Check the L+ supply voltage.
On
Supply voltage L+ is present and OK. ---
