If the user has switched the light OFF (by a linked switch)
then it can be turned ON again by occupancy sensor input
only after
OccAutoOnDelay
(default 15 minutes).
Light Level Sensor
One light level sensor can be linked to enable open-loop
dimming for daylight harvesting. The system then adjusts
the output light level according to incoming natural light.
The light level sensor should therefore be placed at a
position facing the window or skylight where it is not or only
minimally influenced by light from the fixtures.
If a light level sensor is linked, the LED controller will by
default activate daylight harvesting with continuous open
loop dimming according to a user-defined dimming curve
based on 5 configurable supporting points and
RampSpeed
.
Each of these 5 supporting points defines the output light
level (
OUT1
…
OUT5
) to be set by the LED controller for a
given reported natural light level (
LEV1
…
LEV5
).
For natural light levels below LEV1, output light level OUT1
is set. Likewise, for natural light levels above LEV5, output
light level OUT5 is set. Linear interpolation is used between
the defined points (e.g. between LEV1/OUT1 and
LEV2/OUT2).
Setting the output light level to 0 will cause the output of
LEDR to go to OFF state.
If the output has been switched on by an occupancy Auto
on event, the
Auto On Light Level
value will replaced by the
dimming curve output value.
If the dimming curve defined light level has been adjusted
by user rocker interaction, the selected light level will be
temporary maintained for a period defined by
LlsAdjustmentDelay
(default 15 minutes).
The light level sensor can alternatively be used to activate an
automatic switching mode between 0% (OFF) and 100%
(
MaxVoltageLevel)
based on light intensity (twilight switch).
This can be achieved by configuring
DaylightingMode
to
2-level mode via remote commissioning.
The thresholds for switching between the two levels are
defined by
PhotoOnThres
and
PhotoOffThres
.
Repeater function
The LED controller provides the option to activate one-level
(repeat only original telegrams) or two-level (repeat original
telegrams or telegrams that were repeated once) repeater
mode for EnOcean radio telegrams.
By default (
RepeatLinkedDevicesOnly
=ON) only messages
from linked devices are repeated. Setting this parameter to 0
will cause all messages to be repeated.
Note:
2-level repeating function and repeating of all
messages (
RepeatLinkedDevicesOnly
=OFF) should only be
used if really needed! Otherwise the system function can be
compromised by collisions of telegrams.
Status messages
The LED controller will transmit a status message
defined by the selected outbound EEP for every change of
its output state or after
StatusMessageTimer
has elapsed.
By setting
StatusMessageTimer
to 0 status messages can be
switched off completely. By setting it to
0xFFFF only event
based messages will be sent.

Troubleshooting
Problem
Solution Checklist
The device does not power up
Check the wiring for errors
Check the circuit breaker
Use a voltage meter to confirm power
The device does not control
linked load
Click the DIM button to open/close
the relay manually
Turn off the power and then restore it
Cannot link a device
Move closer to the device; it may be
out of range
Try linking a different device
Check for environmental conditions
that interfere with RF signals
Verify the maximum number of 32
inbound devices has not been
exceeded and not more than 1 Light
Level sensor has been linked
The device does not respond to
wireless messages or selected
settings
Check for environment or range issues
Verify the device is linked
Extend the antenna to amplify the
range: remove it from the groove in
the module, and straighten it.
