8) Optional accessories
• "RADIO" Card
The control unit has a connector for fitting a 4 channel radio card
complete with SM slot. This remote control device functions by
means of transmitters which act on the inputs as per the following
table:
Output Receiver
Control unit input
N° 1
STEP-BY-STEP
N° 2
AUX (reset value: Partially Open 1)
N° 3
"Open only"
N° 4
"Only close"
9) POA1 control unit maintenance
As the POA1 control unit is electronic it requires no particular mainte-
nance. However, at least every six months the efficiency of the entire
9.1) Disposal
This product is made from various kinds of material, some of which
can be recycled. Make sure you recycle or dispose of the product in
compliance with laws and regulations locally in force.
10) What to do if...
This section will help fitters to solve some of the most common prob-
lems that may arise during installation.
No LEDs are on:
• Check whether the control unit is powered (measure a voltage of
about 32Vdc at terminals 9-10).
• Check the 2 fuses, if not even the P1 Led is on or flashing a seri-
ous fault has probably occurred and the control unit must there-
fore be replaced.
The P1 LED flashes regularly but the INPUT LED's do not
reflect the state of the respective inputs.
• Switch the unit off for the moment in order to exit a possible pro-
gramming phase.
• Carefully check the connections on terminals 11 to 16.
The "Automatic search" procedure does not start up.
• The "Automatic search" procedure only starts if it has never been
performed before or if the memory has been deleted. To check
whether the memory is empty switch off the unit for a moment.
When it is switched on again, all the Leds should flash rapidly for
about 6 seconds. If they only flash for 3 seconds, the memory
already contains valid values. If a new "Automatic search" is
required, the memory must be completely deleted.
The "Automatic search" procedure has never been per-
formed but it either does not start or it behaves incorrectly
• The system and all the safety devices must be operative in order
to activate the "Automatic search" procedure.
• Make sure that no device connected to the inputs cuts in during
the "Automatic search" procedure.
• In order for the "Automatic search" procedure to start correctly,
the input Leds must be on as shown, the P1 Led must flash once
a second.
• PS124 Buffer Battery
PS124 buffer batteries can be used to supply the control unit in
case of network blackouts.
system must be checked according to the information described in
the "Testing" chapter.

Some electric components may contain polluting sub-
stances; do not dump them.
The "Automatic search" procedure was performed cor-
rectly but the manoeuvre does not start
• Check that the safety device (STOP, PHOTO, PHOTO1 and, if
installed, PHOTO2) Leds are on and that the relative command
Led (STEP-BY-STEP or AUX) remains on for the entire duration of
the command.
• If the "phototest" function is activated but the photocells do not
function correctly, the DIAGNOSTICS LED indicates the fault by
flashing four times.
The gate inverts the direction while moving
An inversion is caused by:
• The photocells triggering (PHOTO2 during the opening manoeu-
vre, PHOTO or PHOTO1 during the closing manoeuvre). In this
case, check the photocell connections and input LEDs.
• The current sensitivity device triggers while the motors are moving
(not near the mechanical stops, therefore). This is considered as
an obstacle and causes an inversion. To find out if the current sen-
sitivity device has triggered, count how many times the DIAG-
NOSTICS LED flashes: 1 flash indicates that the current sensitivi-
ty device triggered on account of motor M1, 2 flashes indicate that
this was caused by motor M2.
