2 Product description
SI GN O is an electromechanical barrier operator including foundation plate, bracket for attachment of a rectangular section arm, and control unit.
The automation system is designed to reach its stroke limit positions (opening and closing strokes) with a deceleration phase, while monitoring motor load during the movement.
Thanks to these control systems any obstacles encountered in the range of the stroke are identified immediately causing reversal of the direction of movement (current sensor function). The system can be used in "manual",
"semiautomatic” and "automatic" mode with functions such as “Close 0 sec. after Photo”, “Always close" and two types of traffic light signalling. The control unit includes a cycle counter that allows management through time of system maintenance interventions, and it is also prearranged for inclusion of radio receivers with SM slot.
Optional accessories are available for all versions.

Notes on electrical connections
To ensure the safety of the operator and prevent damage to components, while making connections or plugging in the radio receiver the control unit must be disconnected from the mains power supply and the back-up batteries (if present).
To make the connections refer to the electrical diagram in heading 3.5, taking account of the following:
The control unit must be powered via a 3 x 1.5mm
2
cable (phase, neutral and earth); if the distance between the control unit and earth ground is greater than 100 ft an earth electrode must be installed in the immediate vicinity of the control unit
To connect the flashing light and electric lock we recommend using a cable with minimum wire section of 1 mm
2
For connections of the safety low voltage part of the safety circuit use wires with a minimum section of
0.25 mm
2
; (use shielded cables if the length exceeds 100 ft, connecting the shield to ground only on the control unit side).
Pay attention to devices with polarity (flashing light, electric lock, phototest, services, etc.).
NC (normally closed) type inputs, when unused, must be jumpered with the "24 Vdc Common"; NO
(normally open) type inputs, when unused, must be left open.
Contacts must be strictly mechanical and free of any type of electrical potential; "PNP, "NPN", "Open
Collector" etc. type switching inputs are not permitted.
3.8
Description of the Stop input
The control unit can be programmed to operate with two types of STOP input:
NC type STOP input: for connection of devices with a normal closed output (factory setting).
Constant resistance STOP: for connection of devices with a constant resistance output of 8.2K
(e.g.
safety edges). In this latter case the control unit measures the resistance connected across the STOP input and the services common terminal and disables the activation when the measured value moves outside the range defined by 8.2K
+/- 50%.
10
To program the STOP input:
1. Set the dip switches as shown
1 2 3 4 5 6 7 8 9 10 11 12
2. Execute the "save procedure" (heading 4.4), which in this case is required to save the status of the STOP input in teach-in mode.
3. Return the dip switches to the setting indicated
1 2 3 4 5 6 7 8 9 10 11 12
Note.
When the programming procedure is terminated the STOP LED must remain illuminated to confirm that the data have been saved correctly.

3.9
Phototest
The Phototest function is an ideal solution in terms of reliability in relation to safety devices and it makes it possible to achieve "category 2" in compliance with UNI EN 954-1 (edition 12/1998), in relation to the combination of control unit and safety devices. To implement this solution connect the photocells as shown in the following diagram and set dip switch 7 to On (Phototest activation).
FOTO FOTO
Whenever an activation is started all the safety devices are tested and the activation is effectively started only when the test gives positive results.
3.10 Checking the connections.
The following operations involve work being carried out on live circuits. Some parts carry mains voltage and are therefore extremely dangerous! Pay maximum attention to what you are doing and never work alone!
When you have finished making the connections it is good practice to perform a general check as follows:
Power on the control unit and immediately check for the presence of mains voltage on terminals 1-2 and between 28 and 33 volts on terminals 9-10 (services output). If the values do not correspond to the above specifications, disconnect the unit immediately and check the connections and power supply voltage carefully.
Approximately 2 seconds after power-on the OK LED should start flashing at regular intervals of one second to indicate that the control unit is functioning correctly.
Check that the LEDs relative to the STOP and Photo inputs are illuminated (safety devices active), while the LEDs relative to the step-by-step and open/close inputs must be extinguished (no command present); if this is not the case check the connections and ensure that the various devices are functioning correctly
Check that all the safety devices in the system are functioning correctly (emergency stop, photocells, pneumatic safety edges, etc.); whenever the safety devices trip the relative STOP and Photo LEDs must switch off.
Release the barrier and check that: the arm is balanced – if it is not, adjust the balancing spring the arm is free to move without undue resistance throughout the entire range of motion the limit switches are functioning correctly: with the bar closed only the closed limit switch LED
11
must switch off; when the arm is open only the open limit switch LED must switch off; if this is not the case, disconnect the power supply and invert the limit switches connector leave the arm at an angle of approximately 45° so that it is free to move in the opening and closing directions, and then lock the barrier
Check that the arm moves in the correct direction, i.e.: press the Close button and check that the arm moves in the closing direction if the arm moves in the opening direction press the Close button again to stop the movement, then disconnect the power supply and invert the positions of two of the motor feeding wires irrespective of the direction of movement of the arm, it is advisable to stop the movement immediately by pressing the Close button again
4 Programming and adjustments
If the check performed on the various connections produces positive results, you can now start the mechanical stops search phase. This procedure is necessary because the SIA20 control unit must measure the distance travelled by the gear motor to bring the arm from fully closed (position 0) to fully open (position 1).
The mechanical stops search procedure can be performed using initial search mode or automatic search mode.
Following the "initial search" or "automatic search", if you wish you can edit the RA and RC deceleration positions by means of a manual programming procedure.
1
RA
Position 0: this is the point at which the arm is in the closed condition, corresponding to the closing stroke mechanical stop.
Position RC: this is the position at which the arm must start its deceleration phase during the closing cycle.
Position RA: this is the position at which the arm must start its deceleration phase during the opening cycle.
Position 1: this is the point at which the arm is in the fully open condition, corresponding to the opening stroke mechanical stop.
RC
0
4.1
Mechanical stops initial search
The "mechanical stops initial search" procedure is executed automatically as the first activation following installation of the barrier.
To activate the mechanical stops initial search:
1. release the barrier, move it clear of the mechanical stops so that it is free to move in the opening and closing directions, and then lock the barrier
2. briefly press the Close button on the board or generate a command pulse on the inputs and wait for the control unit to perform a low speed closing to position 0, a low speed opening to position 1, and a high speed closing to position 0.
Note if after transmitting the command the first movement is an opening, transmit a second command to stop the procedure and then invert the polarity of the motor feeding wires.
3. When the sequence described above is concluded, a mathematical operation is executed to calculate the deceleration positions (RA and RC) automatically.
4. The mechanical stops "initial search" procedure is now terminated and the gear motor is ready for use. Set up the "functions" dip switches as required.
Note 1.
If one of the safety devices should trip or another command pulse is received during the "initial search" procedure, movement of the arm will be interrupted immediately; in this case the above procedure must be repeated starting from step 1.
4.2
Mechanical stops automatic search
As an alternative to the "Initial search" procedure the "Mechanical stops automatic search" procedure can be activated at any time without having to clear the memory. The procedure performs the mechanical stops
12
(positions 0 and 1) search procedure automatically using the same method as that described above for the
"Initial Search" procedure.
To activate the mechanical stops search
1. Set up the dip switches as shown:
1 2 3 4 5 6 7 8 9 10 11 12
2. release the barrier, move it clear of the mechanical stops so that it is free to move in the opening and closing directions, and then lock the barrier
3. Briefly press the Close button on the board and wait for the control unit to perform a low speed closing to position 0, a low speed opening to position 1, and a high speed closing to position 0.
Note if after transmitting the command the first movement is an opening, transmit a second command to stop the procedure and then invert the polarity of the motor feeding wires.
4. When the sequence described above is concluded, a mathematical operation is executed to calculate the deceleration positions automatically.
5. Return the dip switches to the positions shown:
1 2 3 4 5 6 7 8 9 10 11 12
6. The mechanical stops "automatic search" procedure is now terminated and the gear motor is ready for use.
Set up the "functions" dip switches as required.
Note 1.
If one of the safety devices should trip or another command pulse is received during the
"automatic search procedure", movement of the arm will be interrupted immediately; in this case the above procedure must be repeated starting from step 1.
4.3
Manual programming of deceleration positions.
This procedure involves the manual input of the positions for the start of deceleration as an alternative to the positions calculated automatically with the initial or automatic mechanical stops search procedure.
To program the deceleration positions manually:
1.
Set up the dip switches in accordance with one of the following diagrams depending on the parameter to be saved
POSITION RC: Deceleration start position during the closing cycle
1 2 3 4 5 6 7 8 9 10 11 12
POSITION RA: Deceleration start position during the opening cycle
1 2 3 4 5 6 7 8 9 10 11 12
2. Press the Open or Close button on the board and hold it down until the required position has been reached.
Note.
Press the Stop button if you wish to accelerate movement of the bar.
3. Once the position has been reached release the buttons and execute the "Save procedure" ( heading 4.4)
4. Return the dip switches to the positions shown:
1 2 3 4 5 6 7 8 9 10 11 12
4.4
Save procedure
This operation serves to upload the value of the parameter you wish to program to the control unit permanent memory.
13
To perform the save procedure:
1. Hold down the Stop button for at least 3 seconds, after which the OK LED will start flashing at high frequency
2. Release the Stop button. The OK LED will continue to flash at high frequency for a further 3 seconds.
3. Within three seconds press the Open and Close buttons simultaneously and only momentarily ; when the two buttons are pressed simultaneously the OK LED will extinguish and then illuminate for 2 seconds to confirm that the selected parameter has been correctly saved in the memory.
4.5
Memory delete
All programmable parameters are recorded in a non-volatile memory that retains the information also in the event of a mains power loss; in certain cases it may prove necessary to remove all the data you have saved in this memory.
To delete the contents of the memory:
1. Set the dip switches as shown:
1 2 3 4 5 6 7 8 9 10 11 12
2.
Execute the "save procedure" (heading 4.4), which in this case is required to confirm the delete procedure.
3. Return the dip switches to the setting indicated
1 2 3 4 5 6 7 8 9 10 11 12
Note.
When the memory has been reset the system assumes the same status as when the control unit has never been programmed so no movements will be possible; in this case the first command that is transmitted to the inputs or pressing either the Open or Close buttons serves to activate a "Mechanical stops initial search" procedure
Note 1.
This operation does not delete the counter values for the number of cycles executed and the number of cycles programmed.
4.6
Adjustments
When the programming phase is terminated you can make the small number of indispensable adjustments necessary to ensure correct and safe operation of the automation system.
4.6.1 Torque adjustment
To limit the torque levels delivered by the transmission system in accordance with established standards, the control unit is equipped with a trimmer (TR1) that serves to adjust motor torque. Turn the trimmer clockwise to increase torque. If an obstacle is encountered during movement of the arm (motor torque demand higher than programmed torque), the system will stop and, if a semiautomatic or automatic movement was in progress the arm will reverse in the opposite direction. To increase safety levels, if the detection of an obstacle occurs three times in succession before the bar has reached its correct closed position, the system will execute a brief inversion of travel direction and then stop.
4.6.2 Speed adjustment
To limit the kinetic energy of the bar in the event of impact with possible obstacles, apart from restricting motor torque it is also possible to reduce the speed of motion. The speed can be adjusted at any time by means of trimmer TR2: turn the trimmer clockwise to increase speed. When the trimmer is set to the maximum speed position barrier opening time is approximately 3 seconds; with the trimmer at its minimum speed position the opening time is approximately 6 seconds.
4.6.3 Pause time adjustment
When the automatic closing function is selected, after an opening movement a timer is triggered (pause time); when the timer interval elapses the close cycle is started automatically. Pause time can be adjusted by means of trimmer TR3. With the trimmer in its minimum time position the pause time is 0 seconds; with the trimmer in the maximum time position (fully clockwise) the pause time is 120 seconds.
14
5 Testing and commissioning
This is the most important operation, designed to guarantee the maximum safety and reliability of the automation system. The testing procedure can also be used as a periodic check of the devices that make up the automation.
Testing of the entire system must be performed by qualified and experienced personnel who must establish which tests to conduct on the basis of the risks involved, and verify the compliance of the system with applicable regulations, legislation and standards.
Each component of the system, e.g. the emergency stop device, photocells, etc. may require a specific testing phase. We therefore recommend observing the procedures shown in the relative instruction manuals.
Execute the following steps for the testing procedure:
1.
Ensure that the instructions outlined in the "WARNINGS" chapter have been observed in full.
2. Set the dip switches as shown:
(all functions disabled and semiautomatic operating mode)
1 2 3 4 5 6 7 8 9 10 11 12
1. Press the Open button and check that: the flashing light is activated an opening cycle is started with the acceleration phase the movement is decelerated and then stops when the arm is in the open position.
2. Press the Close button and check that: the flashing light is activated a closing cycle is started the movement stops when the arm is closed.
3. Start an opening cycle and check that tripping of a safety device connected to the:
Stop input – causes immediate interruption of the movement
Photo input – has no effect
4. Start a closing cycle and check that tripping of a safety device connected to the:
Stop input – causes immediate interruption of the movement
Photo input – causes the movement to be stopped and restarted in the opposite direction
5. Engage a safety device connected to: the Stop input, and check that when a command input is activated the system will not operate.
the Photo input, and check that when a close command input is activated the system will not operate.
6. During an opening or closing cycle, impede movement of the arm with an obstacle and check that the gear motor performs a direction reversal before the torque level specified by applicable standards is exceeded.
7. Measure the impact force. If control of "motor torque" is used to assist the system for the reduction of impact force, search for the setting that provides the best results
8. Check that the activation of the inputs (if connected) causes a step in the following sequence for the Step-by-Step input: Open – Stop – Close – Stop, for the Open input: Open – Stop – Open – Stop, for the Close input: Close – Stop – Close – Stop
9. Return the dip switches to the setting indicated

Functions description
Man Present Function
The movement is performed only when the command is present. The movement stops as soon as the command is suspended, when one of the safety devices trips ("Stop" or "Photo") or if the current sensor trips.
Once the cycle has been interrupted the input command must be deactivated before another command can be transmitted to activate the arm.
Semiautomatic and automatic function
In "Semiautomatic" or “Automatic” mode following a command pulse the entire movement is executed until the specified position is reached. A second pulse on the same input that started the movement will cause a system Stop. If a control input is supplied with a continuous signal instead of a pulse, this will result in a priority condition wherein all the other control inputs are disabled (this function is useful, for example, if a clock is to be connected to the opening input). Tripping of the current sensor or a photocell involved in the direction of motion during a cycle ("Photo" during the closing cycle) will result in a direction reversal.
In Automatic operating mode, an opening cycle will be followed by a pause and then a closing cycle. If the
"Photo" safety device trips during the pause interval, the timer will be reset with the preset pause time; if the
"Stop" input trips during the pause interval the re-close function will be cancelled and the system will assume
Stop status.
Always Close function
Automatically starts a close cycle preceded by 5 seconds of preflashing if "arm open" status is detected when power is restored.
Condominium Function
In "Condominium" mode an opening cycle cannot be interrupted by control pulses except for those that result in a closing cycle. During the closing cycle a new control pulse will cause the arm to reverse.
Preflashing
A command impulse activates the flashing light, followed by movement 5 seconds later (2 seconds later in manual mode).
Re-close 0 seconds after Photo if in automatic mode or re-close after Photo if in semiautomatic mode
In automatic mode tripping of the photo safety device in the opening or closing cycle reduces the pause time to
0 seconds irrespective of the preset pause time. In semiautomatic mode tripping of the photo safety device during the closing cycle activates automatic closing with the preset pause time.
Photo also during opening
With this function tripping of the "Photo" safety device causes an interruption of the movement also during the opening cycle; if the "Semiautomatic" or "Automatic" function is selected, after the "Photo" device is disengaged the opening cycle will be resumed.
Phototest activation
16
This function makes it possible to execute a check of the efficiency of all photocells at the start of every cycle, thereby increasing the overall safety level of the system. For further details consult heading 3.9.

The function makes it possible to assign the following type of operation to the Electric lock output (terminals 5 and 6): electric lock (Switch 8 Off) – the output is activated for a few seconds in the opening cycle with the arm closed suction cup (Switch 8 On) – the output is activated at the end of the closing movement and it remains activated for the entire time that the arm remains in the closed position.
Traffic light in one-way mode.
In this mode the SCA output is active with the arm open and during the opening cycle it remains switched on, while it is deactivated when closing and with the arm closed. This makes it possible to connect a green traffic light to the output to signal free transit when illuminated.
Traffic light in both directions.
Setting switch 10 to On, irrespective of the position of switch 9, serves to activate the function "Traffic light in both directions"; the following changes occur in the control unit: the "Open" input becomes "Step-by-Step 2", while the "Courtesy Light" (COR) and "Barrier open indicator light" (SCA) outputs become green traffic light for one direction and green traffic light for the opposite direction as specified in Fig. 5. For each direction of transit a different opening command is set: “Step-by-Step” (PP) to enter and “Step-by-Step 2” (PP2) to exit; in this case two traffic lights are installed with Red and Green signals, connected to the SCA and COR outputs.

Common
In normal conditions the SCA and COR outputs are switched off and consequently also the traffic lights are switched off; when a command is transmitted with PP to enter the protected area, the opening cycle is started and simultaneously output SCA is activated and the green traffic light in the entry direction is activated together with the red traffic light in the exit direction.
On the contrary, if the command for opening is given by PP2 the COR output is activated to activate the green traffic light in the exit direction and the red traffic light in the entry direction. The light will remain illuminated for the entire duration of the opening phase and during the pause phase, if programmed; in contrast, during the closing phase the green and red lights will be illuminated together to signal that the transit priority situation is no longer valid.
The two outputs can be used to drive low power 24 Vdc lamps for a maximum of 10 W per output. If higher power lamps are required then it will be necessary to use relays driven by the control unit outputs to control the traffic lights.
7 What to do if…
The following section describes some of the more common problems that may be encountered during installation of the system.
No LED is on: check for the presence of mains voltage on terminals 1 and 2 and ensure that fuses F1 and F3 are not blown.
The unit fails to start: check that the Stop and Photo safety device input LEDs are active and the motor is locked (release LED extinguished).
A direction reversal occurs during a cycle:
Check whether one of the safety devices has tripped (Photo during the closing cycle) or whether the current sensor has tripped; in this latter case check that the current sensor setting is sufficiently high to allow movement of the arm. If the value is insufficient increase the level by turning the torque trimmer (TR1) in a clockwise direction.
17
High frequency flashing of the OK LED: the power supply voltage is insufficient or an incorrect combination has been selected on the dip switches.
The motor moves slowly: the control unit is executing an alignment procedure; the first trip of the current sensor is interpreted as a mechanical stop.
The motor performs the acceleration phase and then stops: check whether or not the encoder LED is flashing during movement of the motor. The flashing frequency may be higher or lower in relation to the speed of movement. With the motor at a standstill the LED may be
On or Off, depending on the exact angular position at which the motor shaft has stopped.
OK LED steadily illuminated for a few seconds immediately after a command: this indicates a fault in the motor control stage; check the wiring and ground insulation of the motor; if no problems are found, install a new control unit.
8 Manual or release operation
Warning: the release operation must be performed only when the arm is stopped.
Manual operation Fig. 12 must be adopted in the event of a power failure or in the case of system faults. The manual operation will allow free movement of the arm only if installed correctly and with genuine original accessories.
1.
Lift the lock cover disk. Insert the key and turn it clockwise
2.
Turn the release handle counter-clockwise. Move the arm manually
To lock the arm: return the release handle to its original position, turn the key and extract it.
9 Maintenance
Maintenance operations must be performed in strict compliance with the safety directions provided in this manual and in accordance with applicable legislation and standards. Although Signo does not require any special maintenance operations, regular inspections carried out at programmed intervals will ensure longer life of the system and reliable operation of the safety devices. For this purpose all the tests and checks specified in heading 4.1 "Testing" should be performed.
If other devices are installed, adhere strictly to the directions given in the relative maintenance plan.

Planning of maintenance work
To assist planning of maintenance interventions for the entire system the control unit is equipped with a cycle counter that increases its value at each opening cycle. The increase is signalled by a flash of the maintenance
LED (MAN). The cycles counter value is constantly compared to an alarm threshold value (programmable by the system installer) and checked against a warning threshold (set automatically at approximately 6 % below the alarm threshold). When the number of cycles executed exceeds the warning threshold the maintenance LED flashes only during operation of the barrier, while if the alarm threshold is exceeded this LED flashes constantly (when the motor is stopped and during movements) thereby signalling the urgent need for maintenance.
The alarm threshold can be programmed from a minimum value of 1000 to a maximum of 255000 cycles in multiples of 1000.

9.1 Alarm
To program the alarm threshold
1. Set the dip switches as shown
2. Divide the number of cycles to be programmed by 1000
3. In the following table find the combination of dip switches the sum of which is equivalent to the number you have just calculated and set the relative dip switches to On.
