Check Standard
Input voltage: 90–240 V AC
Output voltage: 90–240 V AC
Steady on: The power supply is
normal.
Off: No power supply is available.
Steady on: A fault alarm is raised.
Off: No fault alarm is raised.
Off: The power supply is
abnormal.
Blinking at long intervals: The
device successfully registers with
the ECC800-Pro and the software
runs properly (the indicator blinks
at 0.5 Hz, on for 1s and then off
for 1s).
Blinking at short intervals: The
communication is disconnected or
the device fails to register with
the ECC800-Pro (the indicator
blinks at 4 Hz, on for 0.125s and
then off for 0.125s).
Blinking: The indicator blinks at
super short intervals for 0.5s
(blinking at 10 Hz, on for 0.05s
and then off for 0.05s) and then
turns off for 0.5s. The cycle lasts
for 10s.

3 Routine Maintenance
Troubleshooting
Check the input power
cables if the input voltage
is abnormal.
For details, contact Huawei
technical support.
Check the input power
cables.
Clear alarms by referring to
the ECC800-Pro documents.
Check the power supply.
If the RUN indicator blinks
at short intervals, check
whether the RF_Z antenna
of the ECC800-Pro is
normal and whether the
antenna is shielded. If so,
install the antenna in a
different position. If not,
replace the AC actuator.
