Turning clockwise increases the motor’s operating force.
BJ Trimmer that regulates the loosening of the belt/chain from the track at the end of the clo-
sing operation (available from version 5v12)
7. DIP-SWITCHES
1 on: at the end of opening, the door closes automatically after a time interval set on the trimmer
A.C.T.;
o: closure requires a manual command;
2 on: with the automation running, a sequence of open/close commands activates a door sequence
OPEN-CLOSE-OPEN-CLOSE, etc. (see also dip switch 4);
o: in the same conditions, a sequence of open/close commands activates a door sequence OPEN-
STOP-CLOSE-STOP-OPEN-STOP, etc. (step-step function);
3 on: slowdowns both during opening and closing operations are reduced by 30% (they start after the
factory settings’ ones)
o: factory settings’ slowdowns both during opening and closing operations
When changing the position of Dip-switch n°3, you must carry out the stroke setup
procedure through ENTER of PROG buttons.
4 on: NO-REVERSE function active; the door ignores the closing commands during opening and inverts
the direction of door travel only in the closing phase;
o: on activation of the open-close button, the direction of travel is inverted also in the opening phase;
5 on: the pre-ashing function is enabled;
o: the pre-ashing function is disabled;
6 on: the “photocell check” function is enabled;
o: the “photocell check” function is disabled. N.B. to be used when photocells are not used;
8. FEATURES OF K691M
LED - DL3
As well as indicating the presence of power, this led indicates any errors by means of a set series of
ashing signals:
• Continuous ashing: storage in progress or setup not completed;
• always lit: normal operation;
• 1 ash: backup battery voltage less than 11.3 Vdc;
Check the mains voltage, charge the battery, replace the battery;
• 2 ashes: fototest error;
Disable fototest (dipswitch 6 set to OFF), check photocell operation and relative connection;
• 3 ashes: mains power failure;
check thermal magnetic cut-out (upline of system), check fuses;
• 4 ashes: max. current limit exceeded;
Peak of excessive motor absorption, ensure absence of obstacles along door travel, check motor absorp-
tion under no load and applied on the door;
• 5 ashes: no encoder signal;
check wiring, check encoder, check that the motor rotates freely when powered directly by battery, check
fuse F1;
• 6 ashes: presence of obstacle;
Ensure absence of obstacles along door travel and smooth movement of the door;
• 7 ashes: no memorisation procedure performed;
Perform memorisation procedure.
• 8 ashes: no motor signal;
check wiring, check that the motor rotates freely when powered directly by battery, check fuse F1;
