6.1 - Connecting a radio receiver
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
"Close only"
6.2 - Connecting model PS124 buffer battery
PS124 buffer batteries can be used to supply the control unit in case of network
blackouts. To install and connect the battery, proceed as shown in fig. 10.
6.3 - Connecting the Solemyo system
The control unit is designed to be powered with the "Solemyo" photovoltaic
system (photovoltaic panel and 24 V battery). To connect the Solemyo battery
to the control unit, use the socket on the control unit that is normally used for
the buffer battery (see paragraph 6.2).
IMPORTANT!
- When the automation is powered by the "Solemyo" system, it MUST
NOT BE POWERED at the same time from the electrical mains.
- The Solemyo system can be used only if the "Everything in stand by"
function on the con trol unit is ON and the connections are as shown in
the diagram in fig. 5a.

TROUBLESHOOTING
(troubleshooting guide)
No LEDs are on:
• Check whether the control unit is powered (measure a voltage of about
30Vdc at terminals 9-10 (or 24 Vdc with battery power).
• Check the 2 fuses, if not even the P1 Led is on or flashing a serious fault has
probably occurred and the control unit must therefore be replaced.
The P1 LED flashes regularly but the input LED's L1, L2...L5 do not
reflect the state of the respective inputs
• Switch the unit off for the moment in order to exit a possible programming
phase.
• Carefully check the connections on terminals 11 to 16.
LED P1 flashes every 4 seconds
• The control unit is in "Everything in stand by" status.
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 sec-
onds, 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 performed 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 "Auto-
matic search" procedure.
• In order for the "Automatic search" procedure to start correctly, the input
Leds must be on as shown in fig. 11, the P1 Led must flash once a second.
The "Automatic search" procedure was performed correctly 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 cor-
rectly, 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 manoeuvre, 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 sensitivity device has triggered,
count how many times the Diagnostics LED flashes: 1 flash indicates that the
current sensitivity device triggered on account of motor 1, 2 flashes indicate
that this was caused by motor 2.

PRODUCT MAINTENANCE
As the MC424 control unit is electronic it requires no particular maintenance.
However, at least every six months the efficiency of the entire system must be
checked according to the information described in chapter 3.
