1_Connect terminal 22 of the control board "A" to terminal 6 of the control board "B".
2_Terminal 22 of the control board "B" must be connected to terminal 6 of the control board "A"
3_Connect the GND of both control boards.
4_In order to enable the INTERLOCK function, put DIP 9 in ON on both control boards.
5_Decide which boad must open first in case of simultaneous opening. Put DIP 10 in OFF on the
control board with HIGH priority. Put DIP 10 in ON on the control board with LOW priority.
With DIP9 in ON, the entry of terminal 24 (Stop/No panic) changes use. By
connecting a switch between 21 and 24, it is possible to DISABLE the interlock
function.
LEARNING
WARNING: During programming there must be no obstacles in the door's area or within sen-
sor's detection range, otherwise programming will fail and must be repeated.
The door can't be "helped" manually and the trimmers cannot be changed.
In case one of the following parameters are changed, programming must be repeated: door
leaves' travel, door leaves' weight, opening direction, (see DIP # 4 on SW2).
Press without releasing button P1 on the board. LED DL1 will start flashing yellow, and at the same
time the door will start opening and closing slowly to find the limit switches. At the end the door
will open and close at normal speed.
Once the travel setup is complete, the door must be closed and LED DL1 must flash green.
SENSOR TEST SETTING
• Use only sensors which feature testing wires, connecting these to the wire terminals 17 and 18
of the controller DC20;
• Set DIP #11 and #12 on SW1 to ON in order to enable the test;
• Test will be performed at the beginning of each cycle (except when reversing motion).
