30 - 31 - 32 ENCODER (M1)
IMPORTANT:
• Do not connect auxiliary relays or other devices tot he 18 V DC output (terminals 11 – 12)
to avoid malfunctions of the control unit. Use separated power supply / transformers
instead;
• do not connect switching feeders or similar apparatus close to the automation that
may be a source of disturbance.
LOGIC ADJUSTMENTS
Make the logic adjustments.
Note: when any adjusting devices (trimmers or dip-switches) on the control panel are oper-
ated, a complete manoeuvre must be carried out in order for the new settings to take effect.
TRIMMER
T.R.A. This trimmer may give some extra seconds – other than the ones already
set in learning mode – to the second gate leaf closing delay. Unless neces-
sary, leave it to the minimum value. By turning the trimmer clockwise will
increase the extra the second gate leaf closing delay;
T.C.A. Automatic Closing Time adjustment: from about 1 to 120 seconds (see dip-
switch no. 1);
FR. obstacle detection sensitivity adjustment.
Note: by rotating the TRIMMER FR. clockwise the sensitivity of the gear-
motor to obstacles diminishes and therefore the thrust force increases; vice-
versa, by rotating it counter-clockwise, the sensitivity of the gearmotor to
obstacles increases and therefore the thrust force diminishes.
