5. ADVANCED FUNCTIONS
This procedure must be carried out ONLY by an installer and ONLY during setting up of the system.
For correct setting, before carrying out alterations, bring the chain to the completely closed position (up) (see paragraph 4.2).
5.1 RESET
In case if it is necessary to reset the control unit proceed as follows (total erasing of the memory and deactivation of pre-blinking, photocell test and multi-user function):
1. Remove power supply from the system.
2. Set the selector SW1 on AUT (automatic).
3. Press the red button.
4. Keep it pressed while reconnecting the power supply.
5. Keep it pressed until the flashing signal lights up for the 3rd time.
6. Release the button and wait until the flashing light turns off. The reset is done
6. ENABLING AND DESABLING THE PRE-FLASHING, PHOTOCELL TEST AND
THE MULTI-USER FUNCTION
To modify the status of any of these functions it is necessary to enable the setting mode. in the
phase of learning the control unit automatically goes through all possible functions in which
it is possible to intervene.
The led of the flashing light and the POWER led on the control board indicate that the selected
function each time with a variable number of flashings.
The passage from a function to another one is executed automatically (it is enough to maintain
always pressed the red button).
The control unit starts selecting the first function ( signaled by 1 flashing), successively,
keeping pressed the red button you pass at the second function (signaled by 2 flashings) and
so on. To enable the setting / learning mode proceed as follows:
1. Raise the chain to its upper position (the SW1 switch ha sto be turned to the AUT position).
2. Press and keep pressed the red button.
3. After 4 - 5 seconds the led of the flashing - light executes a series of 8 flashings (notifying
the next entry to the learning mode). Once the series of flashings end the control unit is in
the learning mode. Do not release the red button yet.
4. Once individualized (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 control unit puts in evidence the setting by flashing with a slow
frequence (1 flashing/second) or with a rapid frequence (2 flashings / second) as pointed
out on the next table.
5. Press now the button (see table) correspondant to the new status you wish set for the
selected function. The frequency of flashing will vary according to the chosen mode.
At this point it is possible to modify further functions or, if you have finished, go out from the
setting phase.
7. PROBLEMS AND THEIR SOLUTIONS
Type of 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.
Once a lower command is pressed, the chain rises.
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
In case you want to modify other functions, press and keep pressed the red button.
After few seconds, the control unit will start again to select in sequence the several functions.
Instead if you want to exit from the learning mode, it is sufficient to bring the lever of the
selector Sw1 in manual position, wait 1-2 sec and successively report it in automatic position.
6.1 PRE-FLASHING
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
Connect just one pair of photocells (max 150mA)
Every time the motor is switched on, the control unit 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 executed immediately after that the control unit has received an order of "moving",
but before power is applied to the motor.
In this way, the control unit gets out of the learning mode and prepares itself for the normal
functioning.

Check the presence of the electrical voltage and all the

Replace the fuse with a similar one
Check the connections of the encoder's wires
Invert the Jumpers.
Lift the chain with the manual procedure.
If the chain is already lifted, turn SW1 to MAN, wait 1
second, turn SW1 to AUT.
Try again.
Check the photocell, stop and limit switch input.
If not used they must be bridged to the common.
