1. PRESENTATION
1.1. General features:
This manual describes the commissioning and operation of the SIEMENS LOGO! PLC for the
management of URBACO pneumatic- and hydraulic-driven automatic retractable bollards (1
programme for each type of drive).
This PLC shows 8 inputs, 4 outputs, a LCD display screen and a keypad with 6 keys.
The PLC runs one complete access site with traffic lights.
The use of the upper limit switch is not mandatory. On the other hand, the lower limit switch must be
connected! Both limit switches together ensure the safe operationality and the detection of fails within
the system.
The screen and the keypad are designed to analyse defaults, to programme operations, to set the
date and the time and to visualise real time input/output status.
Programming is done by the user and subject to memory backup conservation (at least 80 hours) in
case of a power outage.
In case of memory loss (e.g. power outage for more than 48 hours), the original programming is
automatically reloaded.
This PLC can only be used in stand-alone configurations. It cannot be connected to any centralisation
network.
The expansion module gives additional functions (control inputs, safety device input, default
indications, bollard position status and vehicle detection).
It is recommended to comply with the following to ensure good use of an access site
controlled by one or several automatic retractable bollards:
SECURITY RULES FOR A GOOD USE OF AN ACCESS SITE CONTROLLED BY
AUTOMATIC RETRACTABLE BOLLARD(S)
So as to ensure a good functioning of the access site, URBACO recommends the following:
- Place a vertical sign post showing «retractable bollard obstacle» ahead;
- Equip automatic systems with traffic lights warning of bollard status or position (red and
amber, blinking)
For access control systems, URBACO recommends that vehicles necessarily stop before the bollard
and wait until it is fully retracted (and respect the red turning to blinking amber if the access site is
equipped with traffic lights) before proceeding.
During the automatic rise of bollards once a vehicle has passed, other vehicles should by no means try
and drive one after the other through access without each stopping before the bollard.
INFORMATION AND EDUCATION OF USERS
The access operator must absolutely inform users how the system works and how properly to use it.
URBACO will not be held responsible in case of mishandling or security rules not being respected.

6.3.2. Operation parameters:
CompTime
CompTime:
Time: Compressor surveillance time
For pneumatic installations: it stands for the maximum length of time the compressor can be operational.
Beyond that limit, it is admitted there must be an air leak.
Default value: set on 5 minutes in our factory.
For optimal operationality, this value must not be less than 1 minute.
For hydraulic installations: it stands for the maximum length of time the hydraulic group can be
operational.
The group only works during bollard rise.
Default value: set on 10 seconds in our factory.
As a general rule, this value must not be changed.
Autom.:
Autom.: Type of operation mode (automatic or manual)
For pneumatic and hydraulic installations:
ON = automatic operation mode: the bollard will automatically rise once vehicle clears access.
OFF = manual operation mode: the bollard needs to be actuated upward again.
Default value: ON (automatic operation mode).
PreWarn
PreWarn:
Warn: Notification time
For pneumatic and hydraulic installations:
Notification (warning) time triggers signal (red light) on for the length of time programmed before the
bollard rises again.
Default value: set on 2 seconds in our factory.
If this value is too high, it favours vehicles following one another.
U.L.S.
U.L.S.: Connection of the upper limit switch
Only for pneumatic installations:
ON = operation mode with upper limit switch
OFF = operation mode without upper limit switch
Default value = OFF (without upper limit switch).
For hydraulic installations, the upper limit switch is mandatory.
URBACO
- 17 -
URBACO S.A.
FreeExit:
FreeExit: Time set for free exit
For pneumatic and hydraulic installations:
This value stands for the length of time a vehicle must be over the free exit loop and on the 2nd safety
loop to trigger the bollard descent.
Default value = set on 2 seconds in our factory
YL
Fix:
Fix: Operation mode of amber light
For pneumatic and hydraulic installations:
ON = amber light is steady
OFF = amber light is flashing
Default value: OFF (flashing).
RL
Fix: Operation mode of red light
For pneumatic and hydraulic installations:
ON = red light is steady
OFF = red light is flashing
Default value: OFF (flashing).
Ctrl.Act
Ctrl.Act:
.Act: Condition sur une commande descente
For pneumatic and hydraulic installations:
ON = descent actuation with vehicle detected present on presence / safety loop N°1.
OFF = descent actuation without presence detection
Default value: ON.
LLS Time:
Time: Operation time of lower limit switch
For pneumatic and hydraulic installations:
This value defines a maximum length of time for detection of lower limit switch default.
If the PLC doesn’t see the lower limit switch has been reached in a preset time, default is reported.
Default value: set on 7 seconds in our factory
If this value is too short, the lower limit switch defaults may be reported too frequently when in fact
bollard is working correctly.
ULS Time:
Time: Operation time of upper limit switch
For pneumatic and hydraulic installations:
This value defines a maximum length of time for detection of lower limit switch default.
If the PLC doesn’t see the upper limit switch has been reached in a preset time, default is reported.
Default value: set on 7 seconds in our factory
If this value is too short, the upper limit switch defaults may be reported too frequently when in fact
bollard is working correctly.
For pneumatic installations, if FDC H = OFF, the time for upper limit switch detection is like simulating a
bollard upward.
SecuTime
SecuTime:
Time: Safety time lapse
For pneumatic and hydraulic installations:
This value defines the time set for activation of safety zone once the bollard is triggered upward. During
that temporisation, any vehicle detected will trigger the bollard down.
Default value set on 5 seconds in our factory.
If this value is too high, it favours vehicles following one another.
Lock:
Lock Time set for bollard locking up.
For hydraulic installations only:
This value defines pressure setting of the hydraulic group when the bollard reaches its upward position.
Default value set on 1 second in our factory.
This value must not be too high to avoid premature wearing and deterioration of the group.
URBACO
- 18 -
User’s manual for the Siemens LOGO! PLC
SVLate: Triggering of solenoid valve delayed
For hydraulics only:
This value is set to delay the solenoid valve command so as to launch the hydraulic group at full rate
Pre-set value: 0.5 second
This value must not be set beyond 3 seconds so as to avoid premature deterioration of the group.
7. OPERATION
7.1. Power on:
(When all connections have been done and when a programme has been downloaded into the PLC)
The bollard is retracted (down).
When PLC is switched on, the programme starts running.
If the loops are clear, the red light flashes for a while before bollard starts rising (adjustable).
The red light flashes or remains steady depending on programming while the bollard is rising.
Once the bollard is upward, the light stays steady red.
7.2. Power outage:
The bollard goes down (retracts).
When power is back on, see §V.7.1.
7.3. Operation on an automatic descent actuation (normal passage):
Autom. = ON and Ctrl.Act = ON:
The descent actuation is only considered if a vehicle presence is detected over presence / safety loop
N°1. In this situation, the bollard immediately goe s down (retracts underground), the vehicle drives
through and the bollard rises again once the safety loops B1 and B2 have been cleared and after time
lapse delay before rise (depending on programming).
Autom. = ON and Ctrl.Act = OFF:
The descent actuation is considered without a vehicle presence being detected over presence / safety
loop N°1. In this situation, the bollard immediatel y goes down (retracts underground), the vehicle drives
through and the bollard rises again once the safety loops B1 and B2 have been cleared and after time
lapse delay before rise (depending on programming)
7.4. Operation: manual mode:
Autom. = OFF:
The bollard goes down with a control impulse on CMD and rises again with another control impulse on
CMD; or the bollard goes down with a control impulse on CD and rises again with a control impulse on
CM (expansion module)
7.5. Operation: forced descent:
When the push button is engaged (I7=0), the bollard immediately goes down (retracts underground) and
remains as such for as long as the button is engaged. When the push button is released, (I7=1), the
bollard rises again as for a normal passage.
7.6. Operation on free exit:
If a vehicle presence is detected at the same time over the free exit loop and the safety loop N°2 for as
long as 2 seconds (adjustable), the bollard will automatically go down (retract).
The bollard rises again as for a normal passage.
7.7. Safety during bollard rise:
When the bollard is rising, any presence detected over safety loops will result in the immediate descent
of the bollard for as long as the upper limit switch is not activated.
URBACO
- 19 -
URBACO S.A.
7.8. Locking in the upward position:
As soon as the upper limit switch is activated (bollard in the upward position), the bollard is locked up
and no detection on loops will make it go down (retract).
7.9. Operation of compressor surveillance (for pneumatic installations):
A dry contact from the pressure gauge is used to control the length of time when the compressor is on
duty. When the motor is on, the contact is closed; when the motor stops, the contact opens. As soon as
the compressor starts, time lapse delay starts as well and if, after 5 minutes (adjustable) the compressor
is still on, one will assume there is an air leak somewhere and operating will stop.
7.10. Compressor management (for pneumatic installations):
The compressor works on its own. The 230V power supply is continuous in normal operating mode. The
pressure gauge built in the compressor controls the start / stop status of the compressor to maintain air
pressure within the circuit.
7.11. Operation of the hydraulic groups (for hydraulic installations):
Motor start / stop actuation is operated from the PLC. The group is only powered to make the bollard go
up. When the upper limit switch is activated, power is supplied to the group for 1 second to set circuit
under pressure before it stops. The solenoid valve built in circulates the oil between the tank and the
cylinder.
Detail of operation stages (standard group):
EV=1 and motor =1: the bollard rises
EV=1 and motor =0: the bollard is maintained upward
EV=0 and motor =0: the bollard goes down (retracts)
7.12. Fail-safe device (negative security) (option):
For pneumatic installations, a NF solenoid valve is connected to the main solenoid valve exhaust. This
solenoid valve is permanently powered (exhaust possible). In case of a power outage, exhaust is no
longer possible and the bollard remains upward.
For hydraulic installations, a specific group is designed with NF solenoid valve and manual descent
lever. The LOGO! programme will also be specific.
7.13. Maximum number of bollards per access site:
For pneumatic installations, the number of bollards is determined by:
1) The solenoids valves used. Each PLC output only tolerates a maximum of 10A current.
2) The type of compressor used. A table chart gives indications on how many bollards are suitable by
compressor.
For hydraulic installations, the number of bollards is determined by:
1) The volume of oil taken from the group tank for the whole circuit.
2) How much time it takes for the bollards to rise compared to applicable standards (max 10 seconds)
7.14. Position Lights:
Red Light:
- Steady when the bollard is upward.
- Flashing when the bollard is in motion (adjustable)
Amber Light:
- Flashing or steady when the bollard is down (adjustable)

Inputs:
A rise actuation and a descent actuation are available to differentiate both actions ordered for situations
with a specific actuator.
The bollard may be forced upward. No descent actuation will then be considered.
A safety input with ‘normally open’ contact allows the use of photocells for instance.
Outputs:
Relay 4 types of information about the access site: Defaults, bollard down, bollard upward and presence

8. MAINTENANCE
No special maintenance is prescribed for the PLC. Technical checkups are however recommended
every now and then to control the overall state of equipment (dust, humidity…), safety elements (vehicle
detection, sensors), operationality of actuators (beepers, contactless cards…) as well as to tighten loose
screws if necessary.
Periodicity of checkups is left to operator’s judgement depending on where the system is installed and
how often it is on duty (intensive use or not).
