4.6 RESYNCHRONIZATION.
This operation must be carried out ONLY if it is repeatedly observed that the chain does not
reach the correct climbing position (or if it try to go beyond it).
The resynchronization operation consists in the upward activation of the chain at reduced
speed in order to find the total climb point.
The movement stops automatically at the point where a mechanical stop is found that hinders
its movement. This position is identified as the end of climb position.
1 - Press the step-by-step button for more than 6 seconds, then release it.
2 - The chain stops momentarily (if moving) and then restarts uphill at a reduced speed (if it
does not happen, restart from point 1)
⚠
3 - The window stops in the presence of a mechanical stop, memorizing the end of ascent
position at this point.
during the resynchronization operation, the intervention of the current sensor
is interpreted as identification of the end-of-raise position. To avoid involuntary
intervention, the sensitivity of the sensor must be significantly reduced compared to
normal operating conditions.
5. ADVANCED FEATURES
This procedure must be carried out ONLY by an installer and ONLY during setting up of the
system.
For correct setting, before carrying out changements, bring the chain completely up (see
paragraph 4.2).
5.1 RESET
In case it is necessary to reset the control board, proceed as follows (total erasing of the race
data and deactivation of pre-blinking, photocell test and multi-user functions):
1. Remove power supply from the system.
2. Set the selector SW1 to AUT (automatic).
3. Press the RED button.
4. Keep it pressed while reconnecting the power supply.
5. Keep it pressed until the FUNC LIGHT led lights up for the 3rd time.
6. Release the button and wait until the FUNC LIGHT led turns off.
The reset is done
6. ENABLING AND DESABLING THE PRE-FLASHING, PHOTOCELL TEST AND THE MULTI-
USER FEATURES
To modify the status of any of these features it is necessary to enable the setting mode.
During the learning phase the control board automatically goes through all possible features in
which it is possible to intervene.
The FUNC LIGHT led on the control board show the selected function with a different number
of flashings.
The passage from a function to another one is made automatically (it is enough to maintain
always pressed the RED button).

7. PROBLEMS AND THEIR SOLUTIONS
Problem
Once a lift command is pressed, the chain does not move.
Once a lift command is pressed, the chain rises for brief time and
then stops.
The programming procedure cannot be activated.
The control panel is powered but the chain does not move.

The chain is not completely lifted.
A normally closed input is not active
The control board starts selecting the first function (showed by 1 flashing), successively,
keeping pressed the RED button you pass at the second function (showed by 2 flashings) and
so on.
To enable the setting/learning mode proceed as follows:
1. Raise the chain to its upper position (SW1 has to be set on AUT).
2. Press and keep pressed the RED button.
3. After 4 - 5 s the led FUNC LIGHT does a series of 8 flashings (notifying the next entry to the
learning mode). Once the series of flashings ends, the control board is in the learning mode.
Do not release the RED button yet.
4. Once found (through the number of flashings of the flashing-light led) the function that
you want to modify, release the RED button. In this way the function is selected. Once
selected the function, the FUNC LIGHT led puts in evidence the setting by flashing with a
slow frequence (1 flash each second) or with a rapid frequence (2 flashes each second) as
pointed out on the next table.
5. Press now the button correspondant to the new status you wish set for the selected
function (see table). The frequency of FUNC LIGHT led flashes will vary according to the
chosen mode.
At this point it is possible to modify further features or, if you have ended, go out from the
setting phase.
In case you want to modify other features, press and keep pressed the RED button.
After few seconds, the control board will start again to select in sequence the several functions.
If you want to exit from the learning mode, it is sufficient to set SW1 to MAN, wait 1 - 2 s and set
SW1 to AUT.
6.1 PRE-FLASHING FUNCTION
The chain movement is always signalized by a pre-blinking, advising the user that the chain is
next to move.
6.2 MULTI-USER FUNCTION
During the opening phase of the chain, every other command is ignored.
Once opened the chain (completely down, it is possible to close it using the step-by-step
command or using the automatic re-closure.
During the closing phase, a step-by-step command blocks and inverts the movement.
6.3 PHOTOCELL TEST FUNCTION
Connect just one pair of photocells (max 150 mA)
Every time the motor is switched on, the control board automatically controls if the photocells
are functioning properly.
This operation increases the security system.
If a photocell is damaged (for instance: output relay stuck) or in case of undesired photocell
input short circuit.
This test is performed immediately after that the control board has received a command to
move, but before power is supplied to the motor.

Check the presence of the electrical voltage and all the connections to the electrical network
Replace the fuse with a similar one
Check the connections of the encoder's wires
Lift the chain with the manual procedure.
If the chain is already lifted, turn SW1 to MAN, wait 1 s, turn SW1 to AUT and try again.
Check the photocell, stop and limit switch inputs.
If not used, they must be bridged to the common.
