Operating Instructions
Dupline Remote Actuator DFA-DI
9. General Information
The Dupline DFA-DI interface is a component of the Dupline installation system and en-
ables the Doepke DFA remote actuator to be triggered via the Dupline bus. With the
DFA-DI all functions of the DFA can be called up via the Dupline bus and the switching
status be indicated. Operation, display and further processing can take place e.g. via PC-
based visualisation programmes, text or touch screen displays or via relay outputs.
The control signals transmitted via the Dupline bus have equal parity with any control
commands supplied via the signal inputs of the DFA.
The board is inserted directly into the DFA which also provides its power supply. Con-
nection to the Dupline bus is established via the terminals of the DFA.
Please observe the directions in the 3930131 operating and installation instructions
which are supplied with the DFA remote actuator.
10. Coding
With the DHK 1 hand encoder each channel can be assigned any address between A1
and P8 via the pin strip on the upper side of the board. When connecting the program-
ming cable ensure that its dot marking is facing away from the board.
The allocation of the channels is as follows:
With channels 1 to 3 the relevant switching operation can be triggered; channels 5 to 7
reflect the actual status of the RCCB or MCB connected to the DFA. Channel 8 is respon-
sible for the feedback of the indicator status of the DFA's control LED.
Functions which are not required should remain uncoded. The coding of the DFA-DI can
be carried out without either supply voltage or Dupline signal. It is retained permanently
but may be overwritten at any time.
11. Installation
The installation may only be carried out by an authorised trained technician.
CAUTION!
The DFA-DI is an open, unprotected circuit board. When touching the DFA-DI any static
charge of the body could damage the board's components. Therefore, before mounting
it discharge body static by touching earthed objects with your hands
