Safety
General instructions
The control unit must only be installed and put into operation by a qualied electrician.
The applicable safety regulations and accident prevention regulations must be ob-
served.
Safety instructions
WARNING!
Exposed, live cables.
Danger of electric shock!
• Only work on the control unit when it is de-energised.
CAUTION!
Destruction of the control unit and other devices through incorrect mounting!
• Ensure that the external pushbutton is designed for the mains voltage.
• Do not wire the control and pushbutton lines with an external voltage, especially
not a mains voltage of 230 V.
• Do not exceed the maximum number of connectable components.
• Only use the intended infrared receiver types.
Intended use
The OT EASY 60 II control unit may only be operated in the operating modes described
in the „Description“ section. All other applications are considered to be inappropriate
use.
If the OT EASY 60 II control unit is not used as intended, there is no guarantee that it
will operate safely.

Description
Description
Function and application
The OT EASY 60 II LED control unit can be used to implement static and dynamic light-
ing concepts.
Function
The OT EASY 60 II LED control unit enables the manual and automatic control of up to
four LED luminaire groups on separate channels. Up to 4 x 16 lighting scenes can be
programmed, called up individually or run through cyclically in up to 4 sequences (e.g.
to simulate daylight).
A colored light mixing system can be set up by assigning LED colors to the outputs.
The functions can be executed via a remote control, pushbutton, switch, timer switch,
motion detector or PC, depending on the installation.
Important denitions
Scene, lighting scene
A lighting scene denes the lighting situation in a room or the color resulting from the
mixing of individual LED colors (red, green, blue).
Example 1: Coloured effect lighting
The LEDs have different colors (red, green, blue, white). They are set to different
brightness levels according to the desired shade of color (mixed color of the room
lighting). This mixing color is a lighting scene.
Example 2: Daylight simulation
White LED modules with different colour temperatures of 3300 K and 6500 K in con-
junction with red and blue LED modules are suitable for daylight simulation in areas
at a great distance from a window front, ceiling lights and task lighting with variable
colour temperatures. Very slow cross fades are imperceptible to the human eye.
Sequence
A sequence is the automatic retrieval of stored lighting scenes and their cyclic play-
back.
Fade time
The fade time is the time in which the lighting system changes from one lighting scene
to the next in sequencer mode.
Cycle time
The cycle time is the time in which the daylight simulation system runs through a
complete daylight cycle.

Description
Operating modes
OT EASY 60 II has three operating modes:
• Lighting control mode: Brightness is adjusted manually, and luminaire groups and
lighting scenes are switched on and off manually.
• Sequencer mode: The stored lighting scenes are called up automatically one after
the other. The fade time between the lighting scenes is adjustable.
• Daylight simulation: The lighting scenes are called up automatically to simulate light
conditions as they change during the course of a day. Lighting scenes and cycle
time (= duration of the „day“) can be adjusted.
Behaviour after a power failure
The LED modules connected to the control unit behave as follows if there is a power
failure:
• Lighting control mode: The last state prior to a power failure is automatically re-
stored.
• Sequencer mode:After the power supply is switched back on, e.g. by a timer
switch, the sequence restarts with scene 1.
• Daylight simulation:After the power supply is switched back on, e.g. by a timer
switch, the simulation restarts with the scene 1.
Connections
The control unit has the following connections:
• Mains connection (A)
• Input for external pushbutton (B)
• Input for EASY signal (C)
• Outputs for connecting LED modules (D)

Installation
Connecting the inputs
Proceed as follows:
Step Task
1 Connect the 4p4c modular connector of the EASY signal line.
2 Strip the power cable, remove the insulation from the phase and neu-
tral wires and connect to the screw terminals.
3 Connect the line of the external pushbutton to the screw terminals, if
applicable.
4 Mount the cable strain relief: Use a rubber adapter and cable clamp
that are suitable for the power cable diameter; see gure.
5 Insulate the PE conductor, if necessary.

Master-slave circuit
In a master-slave circuit, up to 16 DALI EASY or OT EASY control units can be con-
trolled simultaneously via a single remote control, up to two pushbutton couplers or a
single PC.
Note:
Conguration of the master-slave circuit via a PC: see the operating instructions of
the EASY Color Control Software.
Procedure
Proceed as follows to set up a master-slave circuit:
Step Task
1 Disconnect all control units from the mains supply.
2 Connect an external pushbutton to the control unit that is to serve as the
master, or leave the input vacant.
3 For the remaining control units, which operate as slaves, use the bridge
at the input for the external pushbutton.
4 Connect the control units via Y-connectors and connect the connection
lines with each other.
5 Connect the infrared receiver and pushbutton coupler to one of the
Y-connectors (optional).
Note:
Connect a maximum of four infrared receivers and two pushbutton
couplers.
6 Reconnect all control units with the mains supply.
