* The input of the edge is an input with calibrated resistance.
If a resistive edge is being used, close the respective Jumper: J1 for ASC and J2 for ASA.
If a mechanical edge is being used, open the respective Jumper: J1 for ASC and J2 for ASA.
If you do not want to fit an edge, open the respective Jumper and turn ON the short-circuit DSW. 5-ASC, 6- ASA
N.B.: There are two dedicated inputs for the edge, NEVER CONNECT THE EDGE TO THE COMMON TERMINAL
LED
+5V
Power supply of the control circuits. If the LED is OFF, check the fuse F1 (2A).
+24V
Power supply of the motor. If the LED is OFF, check the fuse F3 (10A).
PROG
Flashing light during the normal operation of the control unit.
CH
It indicates that the motor is in the closing phase.
AP
It indicates that the motor is in the opening phase.
Trimmer
PA
It regulates the threshold of the motor torque in the opening phase (max. threshold= clockwise direction).
PC
It regulates the threshold of the motor torque in the closing phase (max. threshold= clockwise direction).
Installation of the control unit
1 After having assessed the characteristics and the risks of the installation, short-circuit all normally closed inputs which are not to be used: Stop (7), FCC (8), FCA
(9), Ftc(10), Asc (11), Asa (13) by using the 6 dip-switches near the removable terminal strip. The correspondences are: 1= Stop, 2= Fcc, 3= Fca, 4= Ftc, 5= Asc,
6= Asa.
N.B.: A microswitch is connected across terminals Com.Fc (1) and Com. (2) and calibrates the stroke when the motor is manually disengaged, if limit switches
are mounted their common terminal should be connected to terminal Com.Fc (1) together with one of the disengage microswitch cables (the other microswitch
cable remains connected to terminal Com. (2) together with any other common pushbutton wires. If the sensitive edge is fitted on the closing or opening edge,
the connections should be made to the inputs "ASC" and "ASA" respectively. Connect terminal "0V"(18) to the green-yellow cable of the earth plant.
2 Connect the control inputs: "P.P." - Step-by-step (6) ,"Apre" - Open (5), "Chiude" - Close (4).
3 Connect the power supply 24Vdc (14,15) to any possible devices connected to the control unit (photocells, receivers,...) keeping the correct polarity. Connect the
flashing light and the "open gate indicator", if present (lamps 24V-3W).
4 After having checked the connections again, power the control unit at input terminals 230Vac (28,29). When the unit is on the leds +5V, +24V, STOP, FTC should
be on. At least one of the FCA or FCC leds should be on. The PROG led should flash.
5 The first operation of the control unit is carried out at reduced speed to measure the gate movement.
• Adjust the trimmers PA and PC to half their value.
• Send an opening control signal (Apre, P.P., remote control).
• The control unit performs a pre-warning flashing and then starts the opening phase. The gate will stop when fully open by a mechanical stop or at the FCA if
this has been mounted. The flashing light does not switch off and after 3 seconds closing starts automatically. The calibration is complete at the end of the
closing phase i.e. on the closed mechanical stop or at the FCC if this has been mounted. The procedure is not completed if the motor is stopped by a control
signal ( PP, Stop, photocell, ...). After the stroke regulation the trimmers PA and PC must be adjusted, allowing limitation of the maximum power supplied to
the motor. To adjust the trimmer PA, while starting an opening operation, move the trimmer towards the minimum value (anti-clockwise) until the limiting
device is trig-gered with a subsequent short movement reversion. Then gradually increase the threshold until an optimal regulation is obtained. The proce-
dure for the trimmer PC is the same and concerns the closing operations.
6 Set the Dip-Switches and the programmable functions according to requirements (it is not necessary to switch the control unit off and on again).
WARNINGS
Manual release
When the motor is released, the normally closed contact connected between terminals Com. (2) and Com.Fc. (1) opens.
When the motor is engaged and a first open signal is given, the control unit will run a new stroke calibration.
Buffer batteries
•
If buffer batteries are used (2x12V in series), to remove completely the power supply to the control unit disconnect the terminal "0V" (18).
•
The built-in battery charger in the control unit needs some days to completely recharge the batteries.
•
During operation with batteries, the motor has a movement speed slightly lower than normal operation, irrespective of the charge level of the batteries.
•
Correct connection of the batteries is as follows:
