ENGLISH
7) Definitions of Trimmers
RV3 - Pause
It defines the duration of the gate’s pause before automatic closure.
RV2 - M2 Delay
It defines the delay between the first wing’s (M1) and the second wing’s (M2) start during the closure phase.
RV1 – Work time
It defines the motors’ work time during the opening or closure phases.
8) Definitions of Dip Switches (Selection of Programs)
SW1 - Dip switch 1
It enables or excludes the kickback (during the opening phase with closed gate) : ON= Kickback enabled OFF=No effect
SW1 - Dip switch 2
It chooses whether the unit will operate in condominium mode or not : ON=Condominium OFF=No effect
SW1 - Dip switch 3
It determines the operation mode of the optical barrier : ON=Photostop OFF=Photo-cell
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
The electronic unit is pre-set for the optional connection of an accessory card called “power regulator”. By means of this card the power supplied to the
motors can be reduced.
Caution: In case failure or anomaly of the power regulator card the motors may operate at their 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 any of the motors 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 motors’ start.
Radioreceiver
The electronic unit is pre-set for the optional connection of an accessory radio receiver card allowing remote control of the gate by means of the radio
transmitter. The channel 1 of the radio receiver card ends with a non-polarized electric contact (relay) directly connected to the
start input. The
channel 2 of the radio receiver card ends with a non-polarized electric contact (relay) directly connected to the 2nd radio channel output. This output
is usually connected to the pedestrian start input, although it may be used also for other applications.
