SAFETY
DEVICES
“
COM - FSW OP
”terminals. Normally closed contact. Connect, to these terminals, any safety device (e.g. photocell,
safety edge, pressure switch etc..) which, by opening a contact, affects the gate’s opening motion, causing it to stop
immediately. When the safety device has been reset, the gate resumes its memory-stored cycle. The status of this
input is signalled by LED “
FSW-OP
”.
• If no safety devices are connected, jumper connect the inputs.
• To connect several safety devices, connect the devices in series.
5. INSTALLING THE RADIO CONTROL RECEIVER BOARD
The control unit is designed to house a 5-pin radio-receiver module. Installation procedure: turn off power and fit the
module in connector
CN5
on the control unit.
To avoid damaging the receiver and thus irreparably compromising its operation, the receiver must be installed
while observing the fitting direction specified in paragraph 13 (connection lay-out).
This done, observe the radio-receiver instructions to store the radio control in the memory.
6. OPERATION WITH ENCODER OR AMPEROMETRIC OPERATION
The control unit has 4
DIP SWITCHES
, which enable selection of either amperometric operation or operation with
Encoder.
Operation with encoder provides greater safety in detecting obstacles and greater repeatability of the deceleration
point.
Operation with encoder requires mechanical stops, or limit-switches, for both opening and closing.
To select operation with encoder, position
DIP-SWITCHES 1
and
2
to
ON
and
DIP-SWITCHES 3
and
4
to
OFF
(Fig.01).
To select amperometric operation, position
DIP-SWITCHES 1
and
2
to
OFF
and
DIP-SWITCHES 3
and
4
to
ON
(Fig.02).
For a correct programming procedure of the control
unit, carry out this operation before programming
the control unit because it radically modifies its
operation.

• Indicated in bold: status of LEDs with gate closed, control unit powered, and both limit-switches installed.
• If the limit-switches are not used, the relevant contacts must be jumper connected and LEDs

must be lighted.
• If no
STOP
devices are connected, jumper connect the input. The

LED must be lighted.
8. OPERATION OF DISPLAY
The control unit has a handy display for viewing and programming the operating parameters. Furthermore, it constantly
shows gate status during normal operation.
When operating parameters are being displayed and programmed, the display shows the se-
lected parameter on the left, and its set value on the right. Fig. 03 shows the viewing example of
parameter “
A
” at value “
2
”.
