5- Install the electrical panel at not more than 10-12 m from the motor reducers. When the control
circuits comprise very long lines (over 50 m) it should be decoupled with relays installed in the
control panel.
6- The ducts entering and leaving the equipment must be preferably installed by keeping the initial
level of protection unaltered (IP43).
7- If a fuse blows, it must be replaced with another one of the same type.
8- Connect the Normally Closed contacts that are not used to the common.
TESTING THE INSTALLATION
The small green LED's indicate N.C. inputs, if the contacts are closed the LED's must be on (if N.C. inputs
are not used, they must be connected to the common circuit).
L1 red Indicates the pedestrian command is working (on while signal is being received).
L2 red Indicates the step-by-step command is working (on while signal is being received).
L3 green Indicates the stop command is working (off while signal is being received).
L4 green Indicates the photocell input is working (off while signal is being received).
L5 green Indicates the fixed edge – photo device is working (off while signal is being received).
L6+L7 green/red Indicates the card is powered.
L7 green Indicates the card is battery powered at 12 Vdc.
L8 red Indicates terminals 32-33 are powered at 230 Vac.
DIP-SWITCH SETTING
N° 1A STOP BUTTON OPEN/CLOSE
When this dip-switch is OFF the open/close button works as described in under dip-switch
3A.When the dip-switch is ON and any start button is pressed the following phases will
occur:OPEN - STOP – CLOSE - STOP – OPEN etc..
N° 2A PHOTO DEVICE IN THE OPENING PHASE
When this dip-switch is OFF the photo device only cuts in during the CLOSING phase; it
blocks for about 2 seconds and then carries out an opening manoeuvre.
When this dip-switch is ON the photo device ALSO cuts in during the OPENING phase, the
gate stops moving until the obstacle interrupts the beam of the photo device and an opening
manoeuvre will be carried out after reset.
N° 3A OPEN/CLOSE BUTTON IN THE OPENING PHASE ON also enabled in the opening phase.
When the dip-switches are in the OFF position the open/close button only inverts the
direction
the open/close button ALSO inverts
the OPENING phase.
N° 4A AUTOMATIC RE-CLOSING
In the OFF position, the gate will only close after a manual command after it has opened.
In the ON position, the gate is AUTOMATICALLY CLOSED following a set PAUSE time after
it has opened.
N° 5A-6A SLOWING DOWN
The slowing down phase is the final part of the travel of the gate during which the motor
rotates at a lower speed in order to prevent it from stopping too suddenly. The duration of
this phase depends on the pulses read by the encoder during the memorising operation.
