6. If the LEDs are not lit, check the internal connector connections of
PWD22/52. The following measurement can be done:
- Measure the input voltage:
X1-5 = power GND, X1-4 = power + V
7. If the LEDs are lit but the sequence starts again and again, try the
following:
- Check the cable end for short-circuit with neighboring leads.
Unused wires of the PWD22/52 mast cable must be insulated
from each other, for example, by connecting them to void screw
terminals in the junction box.
- Try with a power with a higher current supply capability (the
power supply may go to current limiting state for a short while).
- Try with a higher supply voltage (max. 55 VDC.) This helps the
starting current need.
