7) Definitions of Trimmers
RV3 - Pause
It defines the duration of the gate's pause before automatic closure.
RV3 – Work time
It defines the motor's work time during the opening or closure phases.
8) Definitions of Dip Switches (Selection of Programs)
SW1 - Dip switch 1
It chooses whether the unit will operate in step-by-step mode or in automatic mode.
ON =Automatic OFF=Step by step
SW1 - Dip switch 2
It chooses whether the unit will operate in the mode determined by dip-switch 1 or in condominium mode.
ON=Codominium OFF=No effect
SW1 - Dip switch 3
It enables or excludes the "immediate closing " procedure.
ON=Immediate closing enabled
SW2 – Dip Fix
It determines the operation mode of the J5 auxiliary connector's terminal 5 output.
Opened Dip Fix = electrochain mode
9) Definitions of Protection Fuses
F1 – Mains power fuse (5A)
It disconnects the electronic unit from the power supply mains in case of short-circuit or electric current consumption anomalies.
F2 – Low voltage fuse (2A)
It protects the electronic unit in case of short circuits or overcurrents on photo-cells, electric lock or any other accessory devices connected to the
24 Vac power supply.

10) Technical features

Power regulator
It protects the electronic unit in case of short circuits or overcurrents on photo-cells, electric lock or any other accessory devices connected to the
24 Vac power supply.
Caution: In case failure or anomaly of the power regulator card the motor may operate at its maximum power value. This is why n° 7 note in
the previous chapter "limits to use" must absolutely be put into practice.
Starting of maximum start up power
When the motor starts the unit supplies the maximum power value for approx. 1 sec. Subsequently the unit's power regulator card, if present,
operates. This particular feature allows to overcome the high negative torque at the motor's start.
OFF=No effect
Closed Dip Fix = courtesy light mode
