1 Safety instructions
Electrical devices may only be mounted and connected by electrically skilled
persons.
Serious injuries, fire or property damage possible. Please read and follow manual
fully.
Danger of electric shock. Always disconnect before carrying out work on the device
or load.
Danger of electric shock. Device is not suitable for disconnection from supply voltage
because mains potential even is applied on the load when the output is switched off.
Always disconnect before carrying out work on the device or load. To do so, switch
off all associated circuit breakers.
Risk of destruction of the dimmer and load if the set operating mode and load type do
not match. Set the correct dimming principle before connecting or exchanging the
load.
Fire hazard. For operation with inductive transformers, each transformer must be
fused on the primary side in accordance with the manufacturer's instructions. Only
safety transformers according to EN 61558-2-6 may be used.

7 Troubleshooting
Connected LED lamps or compact fluorescent lamps switch off in the lowest dimming
position or flicker
The set minimum brightness is too low.
Increase minimum brightness.
Connected LED lamps or compact fluorescent lamps flicker
Cause 1: Lamps are not dimmable.
Check manufacturer's instructions.
Exchange lamps for another type.
Cause 2: Dimming principle and lamps do not optimally match.
For HV-LED: Check operation in another dimming principle, reduce connected
load as well if necessary.
11 / 17
82402732 07.06.2021
Dimming actuator, 4-gang Standard

For LV-LED: Check the lamp operating device and replace as necessary.
With the "Universal" setting: Define the dimming principle manually.
Connected HV-LED lamps or compact fluorescent lamps in the lowest dimming
position are too bright; dimming range is too small
Cause 1: The set minimum brightness is too high.
Reduce minimum brightness.
Cause 2: LED dimming principle (trailing edge phase control) does not optimally
match the connected lamps.
Check operation in the "LED (leading edge phase control)" setting, reduce con-
nected load as well if necessary.
Exchange lamps for another type.
Output has switched off.
Cause 1: Overheating protection has tripped.
Disconnect all outputs from the mains, switch-off the corresponding circuit
breakers.
LED (trailing edge phase control): Reduce the connected load. Exchange
lamps for another type.
LED (leading edge phase control): Reduce the connected load. Check opera-
tion in the setting "LED (trailing edge phase control)". Exchange lamps for an-
other type.
Let device cool down for at least 15 minutes. Check installation situation, en-
sure cooling, e.g. provide distance from surrounding devices.
Cause 2: Overvoltage protection has tripped.
LED (trailing edge phase control): Check operation in the setting "LED (leading
edge phase control)", reduce connected load as well if necessary.
Exchange lamps for another type.
Cause 3: short-circuit in output circuit
Disconnect all outputs from the mains.
Eliminate short-circuit.
Switch on mains voltage to the outputs again. Switch the affected output off
and on again.
When a short-circuit occurs the affected output switches off. Automatic restart
when short-circuit is eliminated within 100 ms (inductive load) or 7 seconds
(capacitive or ohmic load). After that lasting switch-off.
.When a short-circuit occurs during the calibration process, the load calibrates
itself again after the short-circuit is eliminated.
Cause 4: load failure.
12 / 17
82402732 07.06.2021
Dimming actuator, 4-gang Standard

Check load, replace lamp. For inductive transformers, check primary fuse and
replace if necessary.
None of the outputs can be operated.
Cause: Manual mode active.
Deactivate manual mode (switch off continuous manual mode).
All outputs off and not possible to switch on
Cause 1: bus voltage failure.
Check bus voltage.
Luminaires flicker or buzz, proper dimming not possible, device buzzes
Cause: wrong dimming principle set.
Installation or commissioning error. Disconnect device and luminaire, switch off
circuit breaker.
Check installation and correct.
If the wrong dimming principle has been preselected: Set correct dimming prin-
ciple.
If dimming actuator calibrates itself incorrectly, e.g. with highly inductive mains
or long load cables: preselect correct dimming principle with commissioning.
LED lamp is dimly lit when dimmer is switched off
Cause: LED lamp is not optimally suited for this dimmer.
Use a compensation module, see accessories.
Use another type of LED lamp or an LED lamp of another manufacturer.

82402732 07.06.2021
Dimming actuator, 4-gang Standard

Load type universal (with automatic calibration pro-
cedure)
electr. transformer (capacitive / trailing
edge phase control)
conv. transformer (inductive / leading
edge phase control)
LED (trailing edge phase control)
LED (leading edge phase control)
The dimming principle of the dimming channel is specified here.
– universal (with automatic calibration procedure):
The dimming channel automatically sets the connected load type. After pro-
gramming, after bus voltage return (without mains voltage) or after switching
on the mains voltage supply of a load output, the actuator calibrates itself
automatically to the connected load. The calibration procedure becomes no-
ticeable during ohmic loads by a brief flicker and lasts up to 10 seconds de-
pending on the network conditions.
– electr. transformer (capacitive / trailing edge phase control):
The dimming channel is set to the trailing edge phase control principle. Ohmic
loads or electronic transformers can be connected to the output.
– conv. transformer (inductive / leading edge phase control):
The dimming channel is set to the leading edge phase control principle. Con-
ventional transformers can be connected to the output.
– LED (trailing edge phase control):
The dimming channel is set to an optimised trailing edge phase control prin-
ciple. HV LED or compact fluorescent lamps optimised for this dimming prin-
ciple can be connected to the output.
– LED (leading edge phase control):
The dimming channel is set to an optimised leading edge phase control prin-
ciple. HV LED or compact fluorescent lamps optimized for this dimming prin-
ciple can be connected to the output.

Level 2
...
Level 7
Level 8 (brighter)
The step value set here is a gauge for the minimum adjustable residual phase angle
of the output signal.
The value set here cannot be undershot in any switched-on operating state of the
dimming channel, i.e. under no circumstances can the light be dimmed darker than
the value set here.

This parameter is used for setting the duration of the switch-on delay.
After receipt of an ON-telegram, the time that can be configured here is started. The
lamp is switched on after the set time has elapsed.
A further ON-telegram during the switch-on delay time re-triggers the time, i.e. the
time set here is started again.
An OFF-telegram received during the ON-delay will end the delay and sets the
switching status to "OFF".
Switch-off delay 0 ... 3599 s (0 ... 59:59 min)
This parameter is used for setting the duration of the switch-off delay.
After receipt of an OFF-telegram, the time that can be configured here is started.
The lamp is switched off after the set time has elapsed.
A further OFF-telegram during the switch-off delay time re-triggers the time, i.e. the
time set here is started again.
An ON-telegram received during the OFF-delay will end the delay and sets the
switching status to "ON".
