SOFTWARE ADDRESSING
After having done the hardware addressing of the card and the terminal, it is also necessary to do the
software addressing of the the local network components. The software configuration of the components of a
local pLAN network must be done:
−
−
During the first configuration of the pLAN local network
At every variation of the pLAN local network components
The software adressing procedure can be executed from a single terminal, as long as all the others have
previously been connected and adressed.

STRUCTURE OF THE MASKS OF THE REGULATION PROGRAM
On the display of the user terminal are visualized all the necessary information for a complete and precise
regulation. The visualization of all the parameters, both reading and writing, is organized in masks.
Every mask has the followings characteristic:
- It is made up of 4 lines and 20 columns.
- In the angle up on the right the identification of the mask is present. Subsequently this angle will be identified
with the wording position home.
- In the first line it is anticipated the space for the name of the same mask and for the visualization of the time and
the date(main mask).
Manuale cod. 75802507A.0411
Page 13 di 51
It is possible to flow down the masks with the keys arrow up/down
The cursor is normally positioned under the home position of the mask. If in the same mask there is some
modifiable fields (to es. password, set-point,) pushing the enter key (
) you moves the cursor from the
home position to the first available field. Using the arrow keys down/up it is possible to modify the field. To
memorize the value just inserted it is enough to press the enter key. Following this the cursor automatically moves
itself on the following available field. Instead, if in the mask they are no other modifiable fields present, the cursor
returns in the home position.
Structure of the mask
The masks of the regulation program are separated in groups. Every group of masks is accessible
pressing a precise key or a combination of keys.

MEANING AND USE OF THE KEYS OF THE USER TERMINAL
To access the masks fort the regulation program it is necessary to use the keyboard on the user
terminal. The keyboard of the termainl is figured.
Manuale cod. 75802507A.0411
Page 14 di 51
User terminal keyboard
The keyboard is made up of 15 keys which can be divided in three groups:
5.1.1
FIRST GROUP
Made by five keys: ON/OFF,Alarm, Up arrow, Down arrow and Enter:
Fisth group of keys
5.1.1.1 ON/OFF KEY
It allows the machine turning ON and OFF. If the unit is Off push one time this key permit to start the
unit. If the unit is already running pushing this key for more seconds permit to shut down the unit.
The status of the unit is shown in the main mask and also by the ON/OFF key led status.
Procedure to be followed:
press the On/Off key once.
Result of procedure:
-the On/Off key led turns ON.
-the On/Off key turns OFF.
5.1.1.2 ALARM KEY
It allows the silencing of the buzzer which has been activated in case of alarm and the resetting of alarms
after the reasons that caused them had disappeared.
Procedure to be followed:
- press the Alarm key once.
Result of procedure:
- if, before following this procedure, there are no active alarms (Alarm
key OFF, buzzer OFF, no alarm messages on display), the display
will show a mask informing about the absence of any alarms. The
mask will disappear if another key is pressed.
- if, before following this procedure, there is at least one active alarm
(Alarm key ON, buzzer ON, alarm message on display), the pressing
Manuale cod. 75802507A.0411
Page 15 di 51
of the Alarm key silences the buzzer and on display appears the
exact message of the alarm which can be the only one or the first of
a series. Now you can check if there are more than one active alarms
and in that case which kind of alarms has been activated. It is
enough to press the Up or the Down keys. In this case if there are
more than one active alarms a list of alarm messages will be
displayed.
- if, before following this procedure, the buzzer has been silenced
and the display shows an alarm mask, you have two possibilities: if
the reasons which caused the alarms have disappeared, the Alarm
key will turn OFF and the programme will automatically return to the
menu mask (this function is called Clear); if the reasons which
caused the alarms have not disappeared, the buzzer will be
reactivated.
-if before following this procedure the buzzer has been silenced and
the display shows any masks (except an alarm mask), the
programme will automatically enter the alarm branch where you can
select the Clear function.
5.1.1.3 UP/DOWN KEYS
AND ENTER KEY
These three key have twice function:
They permit to show all the mask of the loop
Tey permit to change the parameter sown in the mask (set-point, etc.)
To modify the parameter is necessary press the enter key (a). The cursor skip under the parameter. With the up
and down key you can change the value (b). Press on more time the key enter to save the new parameter (c).

SECOND GROUP
This groups hve nine keys: Menù, Maintenance, Printing, Input/output, Clock, Set, Prog, Info and Orange
Key
Manuale cod. 75802507A.0411
Page 16 di 51
Second group of keys
They allow the user to perform any kind of procedures starting from the programming to the parameters simple
display.
Their function is to select the required loop. The above mentionned 5 rubber keys are used for
programming and for parameters display. Once completed the procedures in a loop, which has been
selected by pressing a key, the user only has to press another key to go at once to another mask loop.
The keys share the following peculiar features :
1)
2)
3)
5.2
A green led next to each key turns on when the key is pressed. The led remains ON as long as the loop
of masks is being used. The led is important if the user does not remember which mask loop has been
selected. It is important to point out that only one of the 8 grey keys can be ON, therefore activation of
one automatically deactivates the others. Moreover, the user must remember that the leds will never be
all OFF, because the mask menu is always on display; therefore, the led next to the menu key is ON
even if no procedure is being performed or after a RESET due to a blackout:
In the programme itself there is an automatic function which brings back to display the menu mask and
the led next to the menu key will be turned ON again.If, for example, the last procedure has been the
setting of the printer parameters, for some minutes the last selected mask will remain on display and the
led next to the printer key will remain ON: Once the selected time has elapsed, the led next to the printer
key will be turned OFF, the one next to the menu key will be turned ON and the temperature and
humidity values will be displayed.
Each loop of masks follows an order. This means that by pressing a key the first mask of the
corresponding loop will be displayed. If the user then moves to other masks of the loop and by chance
presses again the same key, the first mask will be displayed again.
6 KEY REMOTE TERMINAL
This display is an accessory and has limited menù access possibilities.
Only 6 keys can be found on the display:
-
ALARM KEY
PROG KEY
ESC KEY (It is the key MENU of the panel display)
UP & DOWN KEY
ENTER KEY
This display has the possibility of being wall mounted and is usefull for applications were it may be necessary to
show only information about the probe reedings or for changing the set-point.
This display gives the possibility of seeing the following loops:
-
MENU LOOP
SET-POINT LOOP + USER LOOP (only with the password)
ALARM CHECKING
Pay attention!
With this display it is impossible to switch the unit ON/OFF or to enter in the night stand-by and
sterilization menu.

power consuption by opening the dedicated terminal (see wiring diagram).
During the UPS working mode the component whith the bigger power consuption:
COMPRESSORS
INTERNAL HUMIDIFIER WHITH IMMERSED ELECRODES
HEATING END POST-HEATING ELECTRIC HEATER
The component not present in the previus list works normally.
6.3
HEAT RECOVERY SYSTEM (HR)
The heat recovery sistem work whith the difference beetween the external air temperature and the room
temperature. If this temperature is bigger or lower then the setted delta (see mask below) the unit start the
recovery system.
During the recovery working the unit control the state of cooling and heating to don’t have problem of not
necessary recovery (es: during cooling is not necessary recovery heat).
6.4
SUPPLY AIR CONTROL (LIMIT)
The high and low supply air temperature problem is solved by many type of working mode.
Manuale cod. 75802507A.0411
Page 18 di 51
High temperature control:
-
ONLY ALARM: after a delay the unit give an alarm.
-
STOP HOT: when the temperature is over the threshold the unit stop the heating component and if,
after a delay, the temperature is already over the unit give the alarm.
-
HEATING + COOLING: when the temperature is over the threshold the unit start modulating the
cooling component and if, after a delay, the temperature is already over the unit give the alarm.
Low temperature control:
6.5
-
ONLY ALARM: after a delay the unit give an alarm.
-
STOP COOLING: when the temperature is over the threshold the unit stop the cooling component
and if, after a delay, the temperature is already over the unit give the alarm.
-
COOLING + HEATING: when the temperature is over the threshold the unit start modulating the
heating component and if, after a delay, the temperature is already over the unit give the alarm.
-
COOLING + POST: when the temperature is over the threshold the unit start modulating the postheating component and if, after a delay, the temperature is already over the unit give the alarm.
ANTIFREEZE SYSTEM
This system work only if the probe and the heating component is installed. This system is used to reduce
the freezing problem on the water coil and work in two different way:
NORMAL WORKING: If the atifreese temperature is below 6°C, durino normal working mode, the
system open the heating at 100%. And if, after a dealy, the temperature is already out of the range the
fan was stopped and appear a signal on the main mask. If the temperature come beck to the normal
status the unit restart whit the normal working.
ATTENTION!
THERE ARE NOT ALARM SIGNALLING!
NIGHT: If durino the night the unt is OFF end the antifreeze temperature is below 6°C the unit open the
hot water coil at 50% to reduce the possibility of freezing coil.
ATTENTION!
THE SISTEM IS ACTIVATED ONLY WHITH THE HOT WATER COIL!
6.6
STERILIZATION CYCLE
This function, activable by dedicated menù, gives the possibility to sterilize the room, the duct end the
unit whit specific gasses like Glutaraldeide. The cycle is splitted in three phases:

UNIT CONFIGURATION: MEANING AND USE OF THE MASKS
7.1
MANUFACTURER LOOP: MASKS FOR THE COMPONENTS CONFIGURATION
This operation is made by Tecnair during the test of the unit and must be repeated by skilled technicians
only in case of microprocessor substitution or anyway by Tecnair LB autorized personel. Through the
configuration we inform the microprocessor of the components ibnstaleld inside the unit, so that it can handle
them and display th eventual alarms.
The information relative to the components installed in the unit (number of compressors, fans, dampers,
humidifier dimensions etc) are all retrievable in the units technical specifications (provided with the oreder
confirmation) and in the electric diagram provided with the unit.
The unit configuration is protected by a password: 0694
ALL SET VALUES ARE STORED WITHIN A PERMANENT MEMORY TO AVOID THEIR LOSS AT THE

ALARM MASKS MEANING
Each alarm situation is signaled by:
Activation of the buzzer incorporated in the user terminal;
Lightening of the red led on the front of the user terminal;
Visualization of the words "AL" on the right hand side angle of the display.
Each alarm mask is identified with a code of two characters situated in the higher left hand side angle of
the display, so to ease the recognition of the mask itself.
Pressing the alarm key the message corresponding to the last activated alarm s visualised. With the

pCO2 TROUBLESHOOTING
9.1
THE UNIT DOESN’T SWITCH ON
The LED on the main board signalling network presence is off, the LCD is off, other LEDs are off
1)
2)
3)
4)
5)
6)
9.2
Check:
the presence of mains power;
that the output voltage of the power transformer is 24Vac/Vdc;
that the 24Vac/Vdc power connector is correctly inserted;
that the overload fuse is in tact;
that the telephone-type cable connecting the terminal (if present)
and the main board is correctly connected.
ON SWITCHING ON ONE OF THESE SITUATIONS ACCURS
the alarm LED is on;
the LCD is blank or displays random characters;
the buzzer is on.
Check:
1)
2)
3)
4)
that the is EPROM correctly inserted
that the pins of the EPROM were not bent when it was inserted;
that the microprocessor chip has not been tampered with:
if so, call the service department.
9.3
ERRONEUS READING OF THE INPUTS SIGNAL
Check:
1) the calibration of the inputs (from the program);
2) the correct power to the main board and the feelers;
2
3) that the power to the digital inputs and power to the pCO are separated. A 24Vac/24Vac, 12VA
transformer can be used.
4) that the connection to the wires from the feelers is as per the instructions;
5) that the probe cables are located far enough away from possible sources of electromagnetic disturbance
(power cables, contactors, high-voltage cables or cables connected to devices with high peak
absorption);
Manuale cod. 75802507A.0411
Page 47 di 51
6)
7)
9.4
that there is not a high degree of heat resistance between the sensor and the probe cap (if present). If
necessary introduce conductive paste or oil into the caps to ensure good temperature transfer;
if there is a probe error or pCO2 conversion error, the checks to be carried out vary according to the type
of probe.
UNUSUAL ALARM SIGNALFROM THE DIGITAL INPUTS
Check:
1) If the alarm signal is present at the input, measure the voltage between the common terminal “C” and
digital input terminal which indicates the alarm, “Cn”:
2) if voltage is present (24Vac or Vdc depending on the power used for the digital inputs) the contact of the
connected alarm device is closed;
3) if the voltage is 0Vac or 0Vdc (see above) the contact is open.
4) If not expressly stated otherwise, the control creates an alarm when it detects open contacts.
9.5
THE PCO CONTINUES TO REPEATEDLY GO INTO WATCH-DOG MODE
That is switches off and on again as if there were a temporary power cut, or randomly activates some
outputs (digital and/or analogue)
Check:
1) that the power cables do not pass near the microprocessors on the main board;
2) that the ratings of the power transformer are correct.
3) that the metal turrets supplied have been used for mounting the main board in the electrical panel.
9.6
THE SERIAL CONNECTION TO THE LOCAL SUPERVISOR DOESN’T WORK
Check:
1) the presence and the correct connection of the serial card RS485 or RS232;
2) that the pCO2 unit’s identification number has been set correctly (see manual on the application
programs);
3) the codes of the serial cables used;
4) that the serial cables have been connected correctly as per the CAREL diagram provided in the
documentation on the supervisor network;
5) that the serial cables are not disconnected.
9.7
THE CONNECTION TO THE REMOTE SUPERVISOR DOSEN’T WORK
Check:
1) that there is power to the Gateway (if present) and the modems;
2) that the Gateway (if present) has been programmed correctly;
3) that the modem used is compatible with that used.
9.8
THE USER TERMINAL IS LOCKED-OUT
Does not respond to the pressing of the buttons
Check that the terminal has not been non disconnected and then reconnected to main board without waiting 2÷3
seconds. In this case turn the pCO2 off and on again with the terminal connected.
