Operational status display

As soon as the actuator is switched on, the device LED is illumi-
nated continually.
After configuring the actuator with the center or a programming
tool, the device LED indicates other device states besides those
described.
More relevant information is provided in the configuration ins-
tructions for the devices and in the system manual.

Behavior after power restoration

After switching the operating voltage on (mains voltage retur-
ned), the actuator checks the respective components. If an error
is detected during this test, it is indicated by a flashing LED. This
is repeated continually and the device starts to work with the
respective functionality.
If the test runs without any errors, the actuator sends a radio te-
legram with the respective status information. The actuator waits
a random delay time before sending so that all actuators are not
sending at the same time when the power returns (after a power
outage or shut-down). During this time, the device LED flashes
(like in teach mode). If the delay time is short, the flashing may
not even be noticeable.

Maintenance and cleaning

This product is maintenance-free. Repairs are only to be done by
trained professionals.
Dimming actuator:
The dimmer HM-LC-Dim1L-Pl has an internal device
fuse! This fuse protects the Triac from greater current
load. If the device becomes overloaded and the fuse is
blown, it can be replaced!
Test the connected load for a defect before putting back into
operation!
Replace fuses with same type fuses only (micro-fuse 5 x
20 mm, 1.25 A slow)!
