2.6 Channel-LEDs
Every channel contains of a LED, which shows the current state of the channel. Additional to the
status, these LEDs show errors of the channels.
The errors are shown as described below:
only one of the channel-LEDs flashes
7 fast flashi g, short ra k, 7 fast flashi g, …
The belonging channel is at the overload mode or has a short circuit at the output.
At the 230V mode a mains voltage failure can additional be recognized. Because often 4
channels are supplied in common, all 4 channels are flashing.
all channel-LEDs flashing
At the four fold actuator, the first channel must be always connected to a load. At the 8-fold
actuator, additional the fifth channel must be connected to a load. Otherwise the actuator
will switch to the error mode and show this by a flashing off all channel-LEDs.
The normal behavior of the actuator is also shown via these LEDs as described below:
switching mode (1 Bit)
The LED shows the switching behavior of the output. If the 2-step controller sends a 1-signal,
the LED is switched on.
continuous mode (1 Byte)/ integrated controller
The LED operates at the PWM mode with the fixed period of 4s and flashes with the cadence
of the control value. At a control value of 50%, the LED will shine for 2s and will be off for 2s.

2.8. Starting up
After wiring, the allocation of the physical address and the parameterization of every channel follow:
(1)
Connect the interface with the bus, e.g. MDT USB interface
(2)
Set bus power up
(3)
Press the programming button at the device(red programming LED lights)
(4)
Loading of the physical address out of the ETS-Software by using the interface(red LED goes
out, as well this process was completed successful)
(5)
Loading of the application, with requested parameterization
(6)
Switch the power supply on
(7)
If the device is enabled you can test the requested functions(also possible by using the ETS-
Software)
