Phototest

Phototest" is the best possible solution for safety devices in terms of reliability and it puts the control unit and safety photocells in "category 2" according to UNI EN 954-1 standard (ed. 12/1998). Before every manoeuvre is begun, the relative safety devices are checked and only if everything is in order will the manoeuvre start. Should the test be unsuccessful (the photocell is blinded by the sun, cables have short circuited, etc.) the failure is identified and the manoeuvre is not carried out. To obtain the Phototest function:

• Set Dip-Switch 10 to ON
• Connect the two photocells as shown in fig. 4a (when using a single pair of photocells) or as shown in fig. 4b (when using two pairs of photocells), where the power supply for the photocell transmitters is not taken directly from the service output but from the "Phototest" output between the terminals (8-10). The maximum current available at the "Phototest" output is 50mA (2 pairs of Nice TX)
• Power the receivers directly from the service output of the control unit (terminals 8-9).

When using 2 pairs of photocells which may interfere with each other, activate the synchronisation function as described in the photocell instructions.

If at a later time the Phototest function is no longer required, set Dip- Switch 10 to the OFF position.

The photocells are tested as follows: when movement is required, it is first checked that all the receivers involved in the movement give their consent, then power to the transmitters is disconnected after which it is checked that all the receivers signal the fact by removing their consent; the transmitters are then powered and the consent of all the receivers is verified once more. Only if this sequence is successfully carried out will the manoeuvre be performed.

Adjustments can be made with the trimmers that modify the following parameters:

Working time (TL):
Adjusts the maximum duration of the opening or closing manoeuvre.

To adjust the working time TL, select the "Semiautomatic" operating mode by moving Dip-Switch 1 to ON and adjust the TL trimmer to halfway along the travel distance. Then run a complete opening cycle followed by a complete closing cycle and readjust the TL trimmer in order to leave enough time for the whole manoeuvre plus a margin of about 2 to 3 s.

If the trimmer is at maximum and there still is not enough time, cut the TLM jumper on the printed circuit near the TL trimmer, in order to provide more working time. If you wish to use the deceleration function, adjust the Trimmer so that the deceleration stage starts 50 - 70cm before the limit switch is triggered. The modification of the working time will be effective starting with the next opening manoeuvre.

Pause Time (TP):
In the "Automatic" mode, this adjusts the delay between the end of the opening manoeuvre and the beginning of the closing manoeuvre.

To adjust Pause Time TP, select the "Automatic" operating mode by moving Dip-Switch 2 to ON and adjust the TP trimmer as required.

Then carry out an opening manoeuvre and check the time elapsed before "Automatic" closing manoeuvre.

Force (F):
Take great care when adjusting the Force (F) trimmer as this may affect the level of safety of the automatic system. Trial by error is required to adjust this parameter, measuring the force applied to the leaf and comparing it with regulatory values.

After the above checks and adjustments, the system can now be tested.

The automation system must be tested by qualified and expert personnel who must establish what tests to perform according to the relative risk.

Testing is the most important part of the whole installation phase. Each single component, e.g. the gearmotor, emergency stop, photocells, etc., may require a specific test phase; please follow the procedures shown in the respective instructions manuals.

To test the control unit, perform the following operations:

1. Function selection:
   • Set Dip-Switch 1 to ON ("Semiautomatic" operation)
   • Set all the other Dip-Switches to OFF
2. Press the "Step-by-Step" button and check that:
   • An opening manoeuvre starts
   • The flashing lamp activates
   • The movement stops when the opening limit switch FCA is reached.
3. Press the "Step-by-Step" button again and check that:
   • A closing manoeuvre starts
   • The flashing lamp activates
   • The movement stops when the closing limit switch FCC is reached CC
4. Start an opening manoeuvre and check that during the manoeuvre the triggering of a device:
   • Connected to the "Stop" input causes an immediate stop and a short reverse run
   • Connected to the "Photo" input stops and reverses the manoeuvre
5. Start a closing manoeuvre and check that during the manoeuvre the cut-in of a device:
   • Connected to the "Stop" input causes an immediate stop and a short reverse run
   • Connected to the "Photo" input stops and reverses the manoeuvre
6. Press the "Step-by-Step" button and make sure that each activation of the input generates a step in the following sequence: • "Open" – "Stop" – "Close" – "Stop"
7. If the "Phototest" function is used, check the test is efficient:
   • Interrupt the "Photo" photocell, then start a manoeuvre and check this is not performed
   • Short the "Photo" photocell contact, then start a manoeuvre and check this is not performed.
8. Perform the tests for detecting Impact Forces as required by EN 12445.

If further functions are activated after testing has finished that could reduce the safety of the system, specific testing of these functions must be performed.

The unit features a set of microswitches used to operate various functions so as to make the system more suitable to user needs and safer in various conditions of use. All the functions can be activated by moving the relative Dip-Switch to the "On" position and deactivated by moving them to "Off".

Some of the programmable functions are linked to safety aspects; carefully evaluate the effects of a function and see which gives the highest possible level of safety.

Use the Dip-Switches to select the various operating modes and add the functions required according to this table:

Description of functions

Here is a brief description of the functions that can be added by moving the relative Dip-Switch to "ON".

In the "Manual" operating mode, the gate will only move as long as the relative control button is held down.
In the "Semiautomatic" operating mode a command impulse will perform the whole movement until the Working Time limit expires or the mechanical stop is reached. In the "Automatic" operating mode, an opening manoeuvre is followed by a pause and then an automatic closing manoeuvre.
The "Always Closes" function comes into play following a power failure; if the gate is open, a closing manoeuvre takes place, automatically preceded by 5 seconds of pre-flashing.

Switch 3: On = Condominium operating mode (not available in the Manual mode)
In the Condominium operating mode, once an opening manoeuvre has started it cannot be interrupted by other command pulses on "Stepby-Step" until the gate has finished opening.
During a closing manoeuvre, a new command pulse will stop the gate and reverse the direction of movement in order to open the gate.

Switch 4: On = Pre-flashing
A command impulse activates the flashing lamp followed by movement 5 s later (2 s later in the manual mode).

Switch 5: On = "Close" 5 s. after Photo <in the "Automatic" mode > or "Close" after Photo <in the "Semiautomatic" mode >
This function, if in the "Automatic" mode, allows the gate to be kept open only for the time required for transit; when "Photo" finishes, the manoeuvre stops. After 5 s a closing manoeuvre will automatically begin. If "Photo" triggers in the "Semiautomatic" mode during a closing manoeuvre the "Automatic" closing manoeuvre is activated with the adjusted pause time.

Switch 6: On = Safety "Photo" also during the opening manoeuvre
The "Photo" safety device is normally just active during the closing manoeuvre; if Dip-Switch 6 is turned "On" the safety device will also trigger during the opening manoeuvre.
In the "Semiautomatic" or "Automatic" modes, the opening manoeuvre will start again immediately after the photocell has been disengaged.

Switch 7: On = Gradual departure
Starts the manoeuvre gradually, preventing the automatic system from being jolted.

Switch 8: On = Deceleration
Deceleration reduces speed to 30% of rated speed in order to limit the force of the impact in the gate's opening and closing areas.
Once the deceleration function has been activated, it will be necessary to adjust the Working Time Trimmer (TL), since the starting of deceleration is connected with the established working time. Therefore, adjust the working time to ensure that deceleration starts approximately 50-70 cm before the triggering of the limit switch.

As well as reducing the speed of the manoeuvre, the deceleration function also reduces motor torque by 70%. For systems requiring elevated torque, this decrease may cause the motor to stop immediately.

Switch 9: On = Brake
At the end of the movement a motor brake procedure is performed, initially slight and then more incisive in order to stop the gate rapidly but without jolts.

Switch 10: On = Phototest
This function controls photocell efficiency at the beginning of each manoeuvre. See the "Phototest" chapter.

Courtesy light in impulse mode:
In this mode, the clean contact of the courtesy light output will remain closed for 1 sec. at the starting of each opening or closing manoeuvre, thus enabling a command impulse to be sent to an external timer.

Courtesy light in standard mode:
In this mode, the clean contact of the courtesy light output will remain closed for as long as required by the opening or closing manoeuvre, plus an additional 60 seconds.

Installing the aerial

The receiver requires an ABF or ABFKIT type aerial to work properly; without an aerial the range is limited to just a few metres. The aerial must be installed as high as possible; if there are metal or reinforced concrete structures nearby you can install the aerial on top. If the cable supplied with the aerial is too short, use a coaxial cable with 50- Ohm impedance (e.g. low dispersion RG58), the cable must be no longer than 10 m.

If the aerial is installed in a place that is not connected to earth (masonry structures), the braid's terminal can be earthed to provide a larger range of action. The earth point must, of course, be local and of good quality. If an ABF or ABFKIT aerial cannot be installed, you can get quite good results using the length of wire supplied with the receiver as the aerial, laying it flat.

Memorising a remote control

When the memorisation phase is activated, any transmitter correctly recognised within the reception range of the radio is memorised. Consider this aspect with care and remove the aerial if necessary to reduce the capacity of the receiver.

The procedures for memorising the remote controls must be performed within a certain time limit; please read and understand the whole procedure before starting. In order to carry out the following procedure, it is necessary to use the button located on the box of the radio receiver (reference A, Fig. 1b), and the corresponding LED (reference B, Fig. 1b) to the left of the button.

Table "B1"	Mode I memorising (each button activates the corresponding output in the receiver)	Example
1.	Press and hold down the receiver button for at least 3 seconds
2.	Release the button when the Led lights up
3.	Within 10 seconds press the 1st button on the transmitter to be memorised, holding it down for at least 2 seconds
N.B.: If the procedure was memorised correctly, the Led on the receiver will flash 3 times. If there are other transmitters to memorise, repeat step 3 within another 10 seconds The memorisation phase finishes if no new codes are received for 10 seconds.
Table "B2"	Mode II memorising (each button can be associated with a particular output)	Example
1.	Press and release the receiver button as many times as the number of the desired output (twice for output no. 2)
2.	Make sure the Led flashes as many times as the number of the desired output (2 flashes for output no. 2).
3.	Within 10 seconds press the desired button on the transmitter to be memorised, holding it down for at least 2 seconds.
N.B.: If the procedure was memorised correctly, the Led on the receiver will flash 3 times. If there are other transmitters to memorise, repeat step 3 within another 10 seconds The memorisation phase finishes if no new codes are received for 10 seconds.

Remote memorising

It is possible to enter a new transmitter in the receiver memory without using the keypad. A previously memorised and operational remote control must be available. The new transmitter will "inherit" the characteristics of the previously memorised one. Therefore, if the first transmitter is memorised in mode I, the new one will also be memorised in mode I and any of the buttons of the transmitter can be pressed. If the first transmitter is memorised in mode II the new one will also be memorised in mode II but the button activating the required output must be pressed on the first transmitter as must the button required to be memorised on the second. You need to read all the instructions in advance so you can perform the operations in sequence without interruptions. Now, with the two remote controls (the NEW one requiring code memorisation and the OLD one that is already memorised), position yourself within the operating range of the radio controls (within maximum range) and carry out the instructions listed in the table.

Table "B3"	Remote Memorising	Example
1.	Press the button on the NEW transmitter for at least 5 seconds and then release
2.	Press the button on the OLD transmitter 3 times slowly
3.	TX Press the button on the NEW transmitter slowly and then release
N.B.: If there are other transmitters to memorise, repeat the above steps for each new transmitter

Deleting all transmitters
All the memorised codes can be deleted as follows:

Table "B4"	Deleting all transmitters	Example
1.	Press the receiver button and hold it down
2.	Wait for the Led to light up, then wait for it to switch off and then wait for it to flash 3 times
3.	Release the button exactly during the third flash
N.B.: if the procedure was performed correctly, the Led will flash 5 times after a few moments.
