2 GENERAL INFORMATION
The safety control unit F3SP-U4P-TGR has been designed to be used
with the dedicated light curtains. (Please refer to sec.11) It cannot be
connected to other light curtains.
The system conforms with the requirements for safety devices of type 4 in
compliance with the international standards stated e.g. IEC 61496-1.
However, the safety system category depends on the light curtain’s type as
follows:
Type 4 light curtain : Safety system category 4 (EN954-1)
Type 2 light curtain : Safety system category 2 (EN954-1)
This safety device is made up of a control unit protected by a plastic housing
so that it can be installed on a DIN/OMEGA rail; it has 32 removable screw
terminals to which it is possible to connect from 1 to 2 pairs of light curtains.
This control unit has the double ‘muting’ function. This function makes it
possible to obtain a “temporarily automatic suspension” of one or both safety
light curtains in order to allow, for instance, the objects passage without
stopping the machine.
The ‘override’ function enables system, to keep the output relays closed even
with intruded rays to enable material transport after a system shutdown.
Both muting and override functions represent a system that require additional
precautions to limit the reduction of the safety level. This precautions have to
be considered carefully.
The muting and override function is available by simply connecting the
F39-A11 muting lamp (or similar yellow bulb type lamp for 24VDC / 3W to
5W) supplied separately.
The presence of a limb or an object interrupting a beam causes the opening
of the safety outputs and the consequent stopping of the connected machine.
It is necessary for the safety sensors to be connected in the right position in
such a way that there isn’t any possibility to climb over or defeat the system.
Do not install the control unit in the corrosive, flammable or explosive gas.
Do not use the cellular phone or transceivers near the control unit.

The unit has been designed in accordance to the following standards:
IEC 61496-1: 1997. Safety of machinery: electro-sensitive
protective devices
- General requirements and test.
FDIS IEC 61496-2: 1997. Safety of machinery: electro-sensitive
protective devices
- Particular requirements for system using
active opto-electronic devices.

3 OPERATION.
The electronic control system of the device is made up of a microprocessor.
By means of the suitable hardware, it continuously control and check the
connected photocells. No interference among the safety sensors is possible
as they are controlled sequentially; it will be thus possible to install one or two
adjacent safety sensors. When one or more beams are interrupted, the
electronic system opens the outputs.
The SLC have been triggered are displayed by LEDs on the housing.
The control-unit can work in two different modes (please refer to par. 7 page
17) which he can carry out the following operations:
The two external buttons that have to be connected are for:
•TEST : This is used to check if the whole system works effectively. By
pressing the TEST button (opening of the contact), this simulates the
interruption of one or more safety sensors. This operation makes the
machine stop, so the system checks can be made according to the
established time and modes. If pressed after a failure detection of the
unit (see the table error code), reset of the system is required.
•RESET button: It is used to start the system, also for manual reset
condition after relay triggering or after an error which can be reset (see
table related to the error codes).
Two different operating modes are available:
1. Automatic reset: The system will start automatically after the beam
intrusion have been removed.
2. Manual reset: The system will remain in safe off condition until the
RESET button have been pressed. This manual reset allows to start
the system only on a wanted action of the user.
During the unit working, no operation set by the user interface involves
functions which can influence the system safety.

4 PRECAUTIONS AND INSTALLATION CRITERIA.
The safety products used must be suitable for the required application,
other influences must also be taken into account such as room
temperature, electromagnetic interference, intense light sources etc.
Please refer to the manual for specification or contact the manufacturer for
details.
4.1 CALCULATION OF THE MINIMUM INSTALLATION DISTANCE.
The safety distance ‘S’ must be sufficient to guarantee that the hazardous
area cannot be reached by the operator up to the moment in which the
hazardous movement stops. Please refer to EN999 or corresponding C-
standards and the safety light curtain’s instruction manual;
The EN 999 uses this general formula
S = ( K x T ) + C
S = safety distance.
T = T1 + T2 +T3
whereas T1 = machine response time in seconds.
T2 = light curtains response time in seconds.
T3 = controller response time in seconds.
K = speed of the body approaching the hazardous area.
C = additional distance calculated or defined based on the optical resolution of the
light curtain.

Notice
•To configure the control unit in such a way that it works with one
single safety light curtain, it is necessary to connect the terminal 31
and 32 to the terminal 29.
•DC power supply units must satisfy all the conditions below in order to
conform to the application directives.
1) The power supply voltage should be within rating (24VDC +/- 10%)
2) The power supply conforms to EMC Directive (industrial environment)
and LOW-Voltage Directive.
3) The power supply uses double insulation between the primary and
secondary circuits.
4) The power supply should include over current protection limited up

align the light curtains. Follow the operating guide as follows:
•Turn off the power supplying the control unit.
•Open the test contact.
•Power the control unit.
•Align the light curtain by observing the LEDs on the control unit: If
the alignment of the light curtain 1 is correct, the LED 1 and 2 are
turned on. If the alignment of the light curtain 2 is correct, the LED 3
and 4 are turned on.
•After the alignment, turn off the power supplying the control unit,
close the test contact and power the control unit again.
•Wait for the control unit to carry out the initial tests.
•At the end of this operation, the unit indicates the right alignment
with the guard led green on.
•Carry out all the checks described in the final checks and in the
routine maintenance operations.
During aligning operations or normal working, check that the light curtains
connected to the same or other units do not interfere with each other.

7.2 MUTING FUNCTION.
7.2.1 DESCRIPTION.
The muting function makes it possible to obtain a “temporarily automatic
suspension” of one or both light curtains in order to allow, for instance, the
objects passage without stopping the machine. As required by the standard, the
control unit has two inputs for the activation of this function. Two separate
muting functions are possible to use.
It is necessary to position and connect the muting sensors in order to avoid void
muting input condition. It is important to remember that the muting function
forces the system keep working and for this reason the muting functionality must
be designed and handled with care.
To use the muting function, it is mandatory to have the F39-A11 muting
lamp connected to the control unit, otherwise the control unit is locked.
7.2.2 INSTALLATION CRITERIA
1 The muting sensors must recognise the material (pallets, vehicles,
etc.) over its full length.
2 The sensors must be arranged in such a way that the material is
recognised even when it is on a pallet or other transporting medium.
3 In case of different transport speeds through the muting area,
consideration must be used on the muting duration.
4 All the light curtains and the muting sensors must be arranged in
such a way that the previous material has already passed the last
muting sensor before the new material has reached the first muting
sensors.
