4 ON: the deceleration function is on and can be adjusted by means of the TL trimmer;
OFF: the deceleration function is off;
N.B. The FIXED time of slowing down in opening phase: last 13 sec. of the planned work time.
The FIXED time of slowing down in closing phase: last 19 sec. of the planned work time.
Increasing the work time (T.L.), the time of slowing down decreases (the slowing down
retards and fi nishes as soon the manoeuvring has already done). We advise to faster the
total work time (T.L.) for few seconds more than the necessary time for the manoeuvring.
5 ON: the pre-fl ashing function enabled;
OFF: the pre-fl ashing function disabled;
6 ON: the "photocell test" function is enabled;
OFF: the "photocell test" function is disabled. N.B.: to be used when the photocells are not
used;
7 ON: monostable function of the CH2 control relay (terminals 21 and 22) enabled;
OFF: bistable (or STEP-BY-STEP) function of the CH2 control relay (terminals 21 and 22)
enabled;
8 ON: with dip-switch 7 ON (monostable function), the N.O. contact remains closed for 180 secs.
(fi xed invariable delay for the timed control of the lights);
OFF: with dip-switch 7 ON (monostable function), the N.O. contact remains closed for 2 secs.
(fi xed invariable delay for commanding a second automatic system);
9 ON: the "opening ram blow" function is on. This permits the release of the electric lock (to be
used only in the presence of an electric lock);
OFF: the "opening ram blow" function is off;
10 not used.

IMPORTANT:

Each pair of terminals attached to an NC contact that is not in use must be short-circuited in order
to ensure the proper operation of the board.
The door's earthing system must comply with current standards. The manufacturer will accept no
liability for any damage deriving from failure to comply with this requirement.
The radio receiver can learn up to a maximum of 8 dip-switches (TXD2, TXD4, BUG2, BUG4,
SLIM, SLIM-C) or rolling codes (BUG2R, BUG4R, SLIM-R) which can be set on the two channels
as required.
The fi rst channel directly commands the control board for opening the automatic device; the second
channel commands a relay for a N.O. no-voltage output contact (terminals 21 and 22, max. 24 Vac,
1 A).
The learning mode (dip-switch or rolling code) is determined by the fi rst radio control device and
remains unchanged until all the codes have been cancelled.
